I own a 2018 Ford Raptor. After a number of years, the stock leaf springs went flat…losing over an inch of ride height and completely losing the ability to carry any load whatsoever. I replaced my rear leafs with Icon leaf springs set in option 2, adding 2.5” to stock ride height. This adjustment made the stock bump stops functionally useless. In fact they are functionally useless from the factory altogether. I replaced the stock bump stops with Raptor specific Sumo Springs. I used their stock mount, two spacers (as recommended by Sumo after showing them pics and measurements), and added a SVC bump stop pad to the axle. These changes completely eliminated axle wrap, wheel hop, and improved ride and handling, and at least visually improved protection to the frame. Shortly thereafter, I changed the front springs to Geiser 3”. The truck drives better than new by a dramatic margin…with much better ability to carry a load and tow.
Good information
I use sumo springs under the back of my Frontier. As delivered, they were a little too tall, so I voided the warranty by cutting one and half "bubbles" out of the height. They now work perfectly. I've run them for a couple years. I pull either a 19' travel trailer or a small two horse bumper pull with it, and the sumo's are a great addition.
We've had a lot of customers do some "custom modification" since the material is so durable but malleable at the same time. Glad they're working for your Frontier Matt!
I love that you actually use these products on your personal vehicles to really see how well they work!!
Thanks
I have a set (yellow version) on my rear in my 2008 Tundra Crewmax. I love it. Definitely recommend if you don't want your rear to sag so much.
You're right about that damn blue locktite on the Fords they use to stop them falling apart. That I why I like my Chevy where it is not hard to take off any nuts or bolts since a lot of them have fallen out already. Like a Rock!
I use Sumo Springs on my Tacoma for squat. They work well.
Thanks for the review Mr. Truck!
You're welcome
I have been using Sumo Springs for about 3 years now and they are outstanding. I put the mid strength ones on the rear of my 2001 Sierra 1500 for pulling an 8,000-pound TT. I don't feel the front ones are necessary. My ride quality empty is virtually unchanged. Mine have about a 1/2 to 3/4" gap above the axle. There is very little squat when loaded, but I do use a Weight Distribution Hitch. The truck is very stable when towing and rides great. I put them on and now I don't even think about them because they are maintenance free. Highly recommend for the rear. It was nice to see your video of them in action.
Thanks
I put AIR LIFT bladder bags in the coil rear springs of my Sienna, adjustable, progressive compression, works like pneumatic sway bar
Too many cheap asses not wanting to spend the money on a proper system like Airlift.
Man, thats slicker than snot on a door knob. Placing an order for the the whole shoot and ka-bang front n rears now. 👍
We sell them at MrTruck.com
I bought a shocker hitch for my gooseneck and it made a world of difference
That's great, I sell them.
Thanks for the idea for my 3500 HD. I really didn't want to spend the money for air bags. Thanks for sharing this video and information Kent. Never heard of Sumo springs before.
You're welcome
Love my sumo springs on my 2019 trail boss Silverado. I tow 4 days a week. Love the no maintenance unlike air bags and maintain factory ride while not loaded
I will be putting these on a 21 Trail boss. What color did you go with? And with the trail boss having the 2" lift, did you use additional spacers?
The whole point of the bump stops is to not be in contact with the axle when parked. Its for situations that when you encounter a large bump and your nearing the end of of your suspension travel, so that your not pushing the axle into the frame rails. Resulting in cracks in the frame rails or axle housing. I am not saying that the sumo springs are not capable of working as advertised. Just saying that there seems to be some confusion about function of the factory bump stops. If your vehicle is loaded and your sitting on the factory bump stops. Than either you are overloaded or your suspension possibly needs replacement due to age and being out of spec.
Well stated. I couldn't agree more with your statement.
You must have a better suspension system on your truck. At 80% payload max, I would beat the hell out of bump stops. I don't know how they figure payloads, but when loaded the bump stop is way too close for the suspension to have effective travel. The squatting truck throws the entire handling and breaking system off not to mention changing the headlight angles, all within payload limits. The only confusion is someone thinking that bump stops are worth a shit.
It looks like the Summo springs are longer than the stock bump stops, just sayin
Very interesting. I installed air bags on my last pickup, so I'm familiar with the effects. They did require adjustments and some maintenance, so these look like a nice improvement.
"Sumo Springs," because you have to wrestle them into place! :)
Hello Mr Truck, it’s essentially a nascar spring rubber up front and a bump stop rear. If I am towing most the time, I have found a set of mono tube Bilstein shocks are the best for over all stability and confidence in white knuckle conditions. Plus Bilsteins only loose like 3% of their damping after a hundred thousand miles.
Someday I'll be able to afford Bilsteins. I know Mercedes likes and they are on top end RV's
MrTruckTV Have you tried Roadmasters Active Suspension?
@@MrTruckTV Not that expensive. Bilsteins are around $125. Install a pair of rears on my 2019 F-150 and the ride improvement was great. Towing is much improved too.
No
Frank The Pussyfooter I had the roadmasters on my 2018 f150. They did not work well with a WDH. I had them at max adjustment. Made hooking up the bars really hard. I had an e2 hitch. Don’t recommend that hitch either.
I have a very old version of these which is a steel coil spring that mounts just like these bolted to the axle harsh ride but they help loaded
I have them on my 15 Tundra Crewmax 4x4 and they make a huge difference when towing. I’ve been contemplating adding the front ones also.
Which color? Black or blue?
Glad to hear. I have a 14 and just ordered a set for front and rear
I think the words you were searching for to describe the factory piece was "jounce bumper" or "bump stop". I use a similar product called Timbrens. I like the install and forget quality of them.
I use sumo springs on my Silverado trail boss. Love them. I had to order from them directly and there great to work with. the 14-18 model Silverado sumo springs don't fit the new 2019 models. Love them.
Great, I'm going to review trailer Sumo next. They will be in my store
What part number and color did you go with? Have a 2019 GMC AT4 and looking to buy these. TIA
MrTruckTV awesome I didn’t know there was sumo springs for trailers. I’ll be waiting for the video. Thanks
Nice video. I have the 2015 F150 and the stock suspension is a joke when trying to tow. I didn't want air ride so we thought to put on the Timbren's on the rear but the space from the axle to the stock bumpstocks were so large you can tell they were probably never touched from driving. I couldn't see the Timbren's being much better. I'll never load or tow 12,000 lbs like you are, so I changed out the rear suspension from the typical 3 pack (2 long 1 short) leafs to a 5 pack (4 long 1 short) and boy what a different night and day. The truck tows perfectly like it should have all along. With no weight or towing it still drive relatively nice and frankly it's a truck so I'm good. After you loaded the front spacers, it would have been nice to see how the rear axles reacted to them installed. I couldn't help but think it might stiffen that up a bit more even. I wonder putting these on with the improved suspension I now have, boy that would be even better!
Thanks, overall handling improved
You need spacers. I have a 2" lifted Ram and needed their spacer kit to use the Timbrens.
I bought these helper springs to help with the sag while towing my TT, unloaded get ready to turn your truck into a horse carriage, when your suspension compress and hit the spring it causes a very harsh ride , I even took the spacer out and yes it was better on lighter bumps but still when the stock suspension compress and hit the spring again harsh ride, basically it stops the dynamics of your suspension travel, and when towing my TT I can fell the truck riding harsh and maybe cause the sumo spring are on my axle cause a very stiff ride and don't allow the suspension to flex down the highway, only good thing about these helper springs is it does reduce sag at a cost for comfort
I took a spacer out of mine to get more wheel travel when empty, which helps. Loaded with a trailer mine does ride smoother.
Yup, they are basically a longer bump stop. They help with sag (which is a visual thing) by not letting the back drop as much. For real leveling and towing safety a WDH is needed. But I could see the value of these if after all other sway and leveling issues are addressed properly, you still need your truck to have a stiffer rear suspension to lessen the squat. Just remember that a stiffer suspension equals a harsher ride for passangers.
@@treefiddy2470 the flip side is that WDH can cause issues and void travel trailer warranties when used off highways. I prefer to level with an adjustable hitch, load weight correctly as best as humanly possible, pull with a suitable truck (3/4 ton or better) and use Sumo springs for any possible sag. Knock on wood, it's worked so far.
I installed these a couple of weeks ago on my 2014 Frontier. They are awesome, especially when towing.
Great
Good info MrTruck
Thanks
I used Supersprings, SSA28, on my 09 F150 for 8 yrs. loved them. With the F150, you needed alternate shackles because the standard ones would contact the frame. Quick swap, back in business. I tower a 5th wheel, 1050 pin weight. Without these, I sagged. Highly recommend.
Good deal
Do not use a soap water mix if you don't want to spend forever getting the fronts on. Use a silicone spray. Works much better and installation is much faster and easier.
We used windex
Great explanation, thanks
You're welcome
Thank You, Mr. Truck.
Very welcome
I put the supersprings on my 2016 F250. It toes so much better but the unloaded ride is way more stiff. Still recommend though.
Sounds like a double blade SSA13, the single blades are smoother. That's why they developed Sumo, for softer ride.
MrTruckTV . Correct, also I can’t spell, toes🤦🏻♂️. Tows!
I've got SumoSprings (SSR-139-40-2) on my 2016 F250 and it rides like it did from the factory unloaded. If you check out our Instagram page you can see more! instagram.com/supersprings
These are game changers
Very nice and keeps your pickup from bouncing around and improves mpg while towing!
the single trucker
Aside from keeping the truck level (aerodynamic) they will not improve mpg. If anything they will decrease it due to added weight.
Good morning mr truck macy video excellent job suspension great 👍 f150 love ❤️
Thanks
My f350 tremor touched the bump stops a bunch with my 10,600lbs trailer. Installed yellow sumo springs and rode like trash!
Very interesting product! Thanks for your expert review. Unfortunately I don't think they make them for my 1995 F150 4wd. I'm getting too much squat even with the trailer tow package
The do make SuperSprings for your truck
95' F150👍💯
When I put my Timbrens on ( Install and camera shots like yours on my channel) , I couldn’t find much info on the sumo springs. It looks like they do a good job without punishing you with overly firm ride quality.I find the timbrens to work well but they really are overly firm for an F150. I took the spacer off for 4wd they were hitting to harsh too soon . They definitely help towing my 14 k gvwr dump trailer.
John DiMartino
Is it smart to pull a 14 k dump with a f150 , probably not legal
Anyone have preferences between these or Timbrens? I'd love to see a ride quality comparison.
The Sumos offer a softer and progressive compression. The Timbren are stiffer and are not remotely progressive in compression.
Maybe the blue ones are better but the black ones are harsh ride. Bouncy as hell
Do you buy the spacers separate?
They come with extra spacers
I prefer timbrens helps better with heavy loads and squat
Sumos on my 2015 f250 they work great
Sounds like this may be my solution to wind sway. 2019 F150 FWD, pulling a 20' TT. I feel like I'm floating all over the road.
Helper springs wont solve your problem with sway , I also use a F150 to tow a 30ft TT, problem is a lot of rv manufactures make ultra light trailers because most people show up at rv dealers with half-ton trucks , problem with the light trailers is the wind can easy push it around causing sway , the only solution is a propride 3p hitch, friction sway control like on the equalizer is not enough to stop sway with light weight TT,
I had a great experience hauling a 26' TT through Wyoming with my 1/2 ton on a windy day. I have the Sumo Springs and use a WDH with the Sway bar in place. Nice thing about the older style WDH is the sway bar is easily adjusted for windy conditions. I don't feel sway bar is necessary in town or in the mountains. You should have 10-12% of trailer weight on your hitch.
@@ramcummins7879
Sounds like a 3/4 ton truck would be an option as well.
Are these interchangeable with your factory bump stops when your not towing? Looking for a solution for being a weekend warrior towing a 5th wheel toy hauler with a Ram 3500.
Loved the video thanks for the info
What engine do you hav in that truck
3.5L EcoBoost
Don’t need them on front unless you have a plow or something up front
Exactly 👍
How about if you have one of those grill guards / bush guards / cow pushers / etc ? ... Plus a winch.
Sumo springs come in blue, black, and yellow with varying capacity/density. How did you choose your black ones?
Because I'm towing a trailer often
What type of recever do you recommend for a 2019 F150 xlt sport? Adjustable none Adjustable?
It would seem if you want to upgrade your suspension you would do it by having your leaf springs upgraded.
I noticed you already had a weight distribution hitch on your truck so obviously the SUMO doesn't take their place???
Would this work with a bigger block in the Rear differential?
Somes with extra spacers to use on the leaf springs
Will you feel or hear contact between your axle and the sumo spring when you're driving unloaded? With the small space between them I don't see how you wouldn't
Usually the spring will maintain contact with the axel
I absolutely never hear a thing and have had mine for 3 years.
How is the ride affected when your unloaded no trailer say hitting bumps ??
It does fine with empty or loaded trailer
Whose the blacksmith with the carpenter hammer and screwdriver?
My youngest son
Mr Truck, I've got a question. I have always run airbags. I'm considering alternatives on my 2021 F250 towing a Montana 5th wheel its about 11,500. Pin is just over 2000 lbs I'm getting about 4 inches of squat. So Summo or AirBags?
That's alot of squat for a light trailer. SuperSprings mrtrailer.com/supersprings.htm
Does the product for the front compress too or does it just increase the spring rate to slow the oscillation?
I would say slow the oscillation, it doesn't much, the rear sumo does compress
@@MrTruckTV 10-4 sir, thank you.
The Coil SumoSprings give you 15-30% capacity on your factory coil - coming in progressively as weight is applied.
So what's the correct color for an F53, 16k lb motorhome?
Wondering if it would of been easier on the front intall if you jacked the front off the ground which would of expanded the coils allowing easier install. Is that manufacturer recommended install instructions to pound them in with a screwdriver and hammer ??
We did lift it up. We installed the front the best way we could. Like an average Joe would do it his garrage
Wouldn't it have been easier to install the front ones by starting at the bottom of the coil and rotating it up?? Or would it not work that way?
Yes, there's more room behind the coils at the bottom, that's how I stared to do it. But the instructions said start at ring #2 from the top. My son Eric did it well
Looks like these are not intended to be ride leveling because they compress. How much did your bumper sag from the unloaded height when you connected the trailer? What is your tongue weight?
They compress but less than the factory leaf springs. Tongue weight was 1160 lbs. I had the load center over the trailer axles. Squat was a couple inches. I could have tightened the WDH and had less
Wouldn't having the proper equalizer hitch take care of this problem when towing? I have a lot of sag with my 18 f150 and looked at these. I think the proper way is for me to upgrade my hitch to a heavier one to distribute my weight. Am I thinking correctly.
I'll still be use my WDH, but I won't have to tighten the spring arms as much
How do you find the sumossprings after a few years?
They work well, but they only work with a load. I went to Roadmaster Active Suspension because they improve the ride with or without a load
Looks like a cool product! Are these better than Timbren SDS?
Yes, these are solid micro fiber, not hollow
Timbrens are better …….
How does this compare to Roadmaster Active Suspension?
It cushions against axle. Roadmaster just uses 1/2 half the leave spring
These look like a great product and easy install. Have you ever compared them to the roadmaster active suspension?
I've seen them, it looks like they work on one side of the trucks leaf springs. I like SuperSprings and SumoSprings
So are these a good alternative to air bags? They seem to do the same things but these never have to be adjusted.
Do they ever wear out? Seems like the would fall apart after getting squished a million times.
There's a lifetime warranty on workmanship
Lifetime warranty. We also have put these under testing where they do 250,000 compressions (typical life of a truck) in a 24 hour period and these come out the other side with the same spring rate. If you're wondering about durability, check out our instagram page where we show some torture testing. instagram.com/supersprings
MrTruckTV
I've got a 1.5 in level on the front of my 2015 F150 6.5 ft box and stock rear. It sits perfectly level with no load. How much will it sag before it engages the Sumo springs? I pull a 7500 lb holiday trailer and want to keep it close to level when hooked to the trailer. Thanks in advance.
Sumo springs come with spacers, so you can have it touch the frame and it might settle 1in
@@MrTruckTV Thank you. I wonder if the ride will be rougher if I use the spacers?
How come no one ever shows the difference in squat before the Sumo Springs and after? That would be a great selling point.
Yes good idea
Anybody know how these things do for a truck bed camper?
I use a 3500 for my 1/2 ton sway, squat and overload problems.
Do they also make these for mid sized trucks?
Yes
Can you add these with 3.5 inch lift ?
Should be able too, they come with several spacers
I have a 2014 F350 Dually. I pull a 5th Wheel at a weight of 16,800 lbs. Hitch weight at 2800lbs Would the sumo springs be to my advantage?
Also, would suggest sumos for front?
Yes, I would just do the rear
Thanks for the video. I have been looking for an assist for the bumper sag I get when towing my heavy boat with my 2013 F150.
You're welcome, doing the trailer Sumo soon
Those new F150's need all the help they can get. I have never seen a truck that lets a load move it around so much.
Kent, these look nice. Would you still recommend them or something else? I’m looking to beef up my 16 F-150 to tow a 6500 Travel Trailer so I’m trying to find the best solution. Thanks.
Yes, I like these for a 1/2 ton and like SuperSprings for F250-350
Better yet, get a weight distribution hitch. Better for steering and braking.
When driving empty\unloaded I've heard they cause bounce back. Any find that occurring?
Yes, good ride loaded, stinks unloaded. Have a 2015 silverado 3500HD 4×4.
Would these help a 3” sag on my 1500? Trailer is well within weight requirements just heavy at the pin when empty and makes the truck squat. Trying to decide between this or airbags. Airbags seem like such a hassle.
Yes
@@MrTruckTV what color would be best suited? Trailer is 4500 gooseneck
I'm holding off on trailer apps. They aren't side enough for some trailers. Waiting on engineers.
If you order an HDPP, it comes with an extra spring to begin with. Just saying.....
creepycharly But it’s still a half ton. Just saying....
@@Icutmetal a half ton with 3200 lbs payload.
Does putting front and rear sumo springs on negatively affect a WDH hitch?
Not that I've seen
Hello Mr. Truck! What are your thoughts on the sumo springs vs the road master active suspension? Trying to beef up my rear suspension on my 2015 f-150 with max tow. Thanks!
I don't know Road Master, I've heard of it
Now I remember Road Master, They are only on 1/2 of the factory spring, don't know long term wear.
Roadmaster is garbage. They told me if my truck left the road the warranty was void. They said going through a pasture was extreme off-roading. Love my sumo springs.
Can I ride with please when you "chase coyotes and bounce and fly in the air" I am afraid to drive that hard anymore to poor. I miss being young and wanting to see how far you can push it. Thanks Mr. Truck.
You're welcome
@MrTruckTV: Thank You Sir For These Sumo Springs automatic overloads Sir & GOD BLESS You...........JESUS is LORD
You should have done yellow in the back since your hauling heavy stuff
Since you have had the sumo springs for awhile, do you still like them?
I like them, I did take one spacer out. I think with more wheel travel, it's a softer ride. But it squats a little more
How much does your trailer weigh?
I thought you were going to smack your truck with that spring. It made me uncomfortable
Are these compatible with Sulastic shackles?
Yes, Sulastics are on the end of your leaf springs, Sumo Springs sit on the axle.
Newbie question, looking to buy a travel trailer for my 2012 f150 fx2 5.0l supercab. There is 130k on the truck, bought it used so the shocks/struts are originals. My question is would the sumosprings help out or just go with Rancho Quicklift Leveling Struts + RS9000XL Adjustable Shocks Set. Or would Rancho be a waste of money. Any advice would be helpful.
Sumo's will support a trailer better
@@MrTruckTV still have 4 more years until I retire, time flying by...great videos.. thanks!!
Hi Mr. Did the ride get stiffer up front?
A little bit, the factory max tow package on the rear, which is a spacer under the leaf springs, makes the rear ride a little stiffer before I added Sumo Springs
Just put sumos on my colorado duramax, looking forward to how it feels pulling my 27 ft 6000 lb camper. Do you think the front coil spacer does anything to the ride height up front? If so wouldn't an alignment be needed?
Loaded with a trailer, it does a little
Are these better than air bags?
Yes
Did you prefer the supersprings or the Sumo?
Sumo's on 1/2 tons, Super Springs on heavy duty
My 2019 ram 1500 has a 2 inch lift in it. Will these work on my ram? I just purchased a 33 foot travel trailer, I would like to put these on to stop the sag and improve the ride
They should, the kit comes with extra spacers
Didn't see them listed for 150 trucks
They are there, I may not have them on my store yet
What was the difference in the initial Squad between stock and sumu Springs
It was two inches, I could have less if I had tightened up the WDH bars
Dose it HELP with the Ford DEATH Wobble on the front end of the F-350 when loaded
I don't think so. death wobble is normally with lifted with short trucks and loose steering linkage. Not sure about a F350
I have just a stock F350. It happens when I hit a good size bump or cross member on overpass usually with a curve. Can’t stop the wobble or bouncing of the front end until I slow to or below 45 MPH
Why would you tow 12800lbs with a 1/2ton?
Because the truck can?
A Throop Sure it can.
Do you still have your f250?
No unfortunately my truck collection is dwindling. We're trying to move farther in the country and scrambling to afford the move. Going to sell Dodgezilla Overkill too
You said this helps prevent tire hop when unloaded?
Yes, it slows down the movement of the rear axle
Truck mechanic using a claw hammer
I don't think using a claw hammer and screw driver is an approved method to install this product...lol...
Dan Hambrick Why not?
If Sumo Springs are anything like Timbrens, then they are junk. Nothing replaces a good quality airbag.
Timbrens are full of hot air, Sumo Springs are micro fiber
@@MrTruckTV I put Timbrens on my Silverado 1500, and not only did I receive a nice pound in the rear unloaded, but when loaded it was an extremely rough ride, and I didnt gain any extra height while loaded. It still had the same squat. Because I was using weight distribution, trailering with these produced no positive results. If you are towing fifth wheel, or are not using weight distribution, then Timbrens may give you positive results. But, not appropriate for my application.
