![Traxxas TRX4 RC Crawler Treal Shock Tower Upgrade [Install, Test, Review]](http://i.ytimg.com/vi/D3YZEPEaDh8/mqdefault.jpg)
Wow now im thinking i might build another rig with lift and see what its capable of Thank for another great video Brother!
Thank you sooo much for making this video
This is the setup I run on my trx4 sport
Great video!!! The owner of my local hobby shop talked me out of the lift kit install, because of the high cog. Now the thoughts are back in my head, THANX!!! 👍👍
Our thoughts exactly!
Awesome video. Currently building a long arm kit for my trx
Man that is sick, haven't seen one yet that has climbed so well !
This is one of best upgrades
That was great brother!!!
surprised us too.
Can confirm. Setup works dope. Just need to trim the body a bit to eliminate rub
I am new in this RC World and are looking to find out which car to buy😄. Your videoes is awesome and helps me to decide 👍👍😄.... Thanks for your help. I like the way you review the cars and kits ... when something is awfull you just say it 👍👍
Great video dude, you have to show how you do 🇨🇷🇨🇷🇨🇷🤜🏻🤜🏻🤛🏻🤛🏻
The link length is to properly position the axle under the truck. If it’s at stock height with the longer arms then the axle will be further away than intended. Conversely, if you keep the stock links at the lifted height the axles will be pulled in more than intended.
So if you want that drop but at the stock height, the. Just delimit the long arm shocks and use them on stock suspension geometry.
What for? What he has now is more capable. lol.
And this is why I run 100mm internally sprung air shocks with no limiters on my Gen7...Droop and portals FTW!
I did this to my Bronco about 6 months ago. I removed the limiters but I didn’t think about using softer springs 🤔. I just took some load off of the stock springs. Good idea though, I’ll get the red cats and check it out. I had to cut maybe 3/32” off of the front and rear of the bottom outer fenders to get my 2.2s to clear during severe articulation. The fender shave is barely noticeable. I also raised the rear bumper up to get rid of the huge gap the lift kit left and mounted it in as far in as possible to eliminate vertical bumper drag. It crawls waaaay better than stock. 👍
Now we're talking. Yeah, get really soft springs that allow you adjustability to raise and lower the vehicle in any situation.
Was it hard to remove the limiters ?
How did you remove the limiters?
@@downhillliam7824 Take the shocks apart and remove them. Look at your manuals shock exploded view or look up a CZcams video. If you think you’re going to have a problem with assembly/disassembly do it anyway. Break parts, modify, fail, fail again, get closer, break parts, modify again, Win!! and learn. I’ve had a lot of mod fails on my build over the years but it articulates like I want it to now. My friend has a stock Bronco and I crawl over tons of stuff that he can’t. I also installed a Hobbywing quicrun fusion FOC 2 in 1 motor. That’s been one of the best upgrades so far IMO. It Hauls Asss and also crawls super slow.
@@Crsh0vrride I just saw your question (a year later lol) but nope.
Completely insane.
Wish you would make a new video of you doing all the work I love it was just wondering how you did it with the lift
I think you're onto something. 👍
Came out better than expected.
Could you link the springs you used for this build 👍🏻
I think they used the Traxxas’s softest spring
here is the part number:
Lift kit =. trx8153
Normal = trx8042 (they are a little bit softer than the lift kit ones)
@@Fl0I They actually used springs off the Gen 8 Redcat ... and apparently you are unable to buy the spring by itself ... so you are stuck buying the whole shock anyway part # RER11343
Just to make it easier on people looking for the spring they used ...Redcat part # RER11434 ... they actually used a Redcat spring off the Gen 8, and apparently you cant buy the spring by itself ... but please feel free to correct me if you are able to find it by itself.
Can you accomplish a similar thing if you use 100mm shocks only? With soft springs and adjusting the preloads for ride height, you could gain 0.4 inches in droop.. Could be worth a try.. I flipped my bumper mounts (raised my bumpers), then raised my body 1/2 inches, and used 14mm spacers and longer screws to raise my running boards up to the rocker panels, then turned my preloads out to lower the center of gravity 1/8 inch, to offset the body height. Only down side is I lost 1/8 inch ground clearance dead center in the truck but the running boards are still higher for more rock clearance and the approach and departure angles are better.. Most of this was all free other than the aluminum spacers and longer screws.. I may also add some weight out on the running boards (principle of levers), to further stabilize, and cut down side roll.. (same principle as a high wire walker uses a long pole, or a kids teeter totter board, where the further out you get from the pivot point the more leverage is applied with minimum weight).. I would like your thoughts on 100mm shocks..
Love all your videos, if you still have this truck I would love to see this go up against your vanquish phoenix portal kit. I have the trx4 builders kit, an scx10.3 and have the vanquish on order. I am considering this for my trx4, any cons that you have run across with this setup?
Love my TRX4 Sport. Much more composed than my Axial SCX10iii
This was eye opening since I'm trying to get my trx4 sport lower hmmmm
Hi... great video by the way... im new to the crawling seen... i want to build a traxxas trx4... what recommendations should i do right from the start?...my plan is to build one from scratch...would you rec. the long arm extension and yeah racing stuff?...i just want to build one right the first time and you seem to be very knowledgeable with crawling and have experience with the traxxas trx4...
I've been running my trx4 like that for a year or more kept the long arm shocks but I run the stock springs then I got cheap Amazon 120mm shocks with the stock springs and it crawls like a spider.
What shocks?
Wow!
Sweet I have the long travel kit on my Bronco with 2.2's Im running the stk springs that came on the shocks I might have to experiment by taking the limiters out. Great video love the articulation very sick.
For sure. they sell the kit with those stock springs since there's zero adjustability with them for crawling.
So what springs ?
Ahhh yes some more paint store crawling haha 👍🏼
Test track! Found some new lines though!
@@RCReviewChannel which springs did you end up using?
Let me first say how much I appreciate your videos. Your channel is my "go-to" for all rock crawler performance, testing, and mods. I've been putting in some heavy research on the Traxxas lift kit. The difference between your TRX with the lift and others that I've seen in night and day different. The flex is great, but your rig seems to be so much lower than others that I've seen. Are the only modifications that you made to the lift: the removal of the spacer, the lighter springs, and the lighter weight oil? Or, did you do something else to lower the body of the truck? I'm really interested in the kit, but only if I can duplicate your performance and results. Any info would be greatly appreciated. Thanks and keep up the AMAZING videos!!
did you ever find out?
@@Crsh0vrride following
All the information is on the video, it's not very hard to duplicate if you listen carefully. All you need is the softer Redcat gen 8 springs.
So I have this setup and I'm struggling to find a way to get the full articulation of the front, did you do anything with the servo/panhard drop to help with that?
I posted a link to a dudes video that explains what you have to do but you have to use a hand dremel but it's totally worth it man!!
czcams.com/video/cCWyoODREik/video.html
I’m gonna set up shocks for it to crawl and also play in the mud. I put the lift in and it needs to actually travel more not jus the taller. I’m thinking maybe the stock springs in the longer shocks and then angle the shocks
Wow the articulation over that curb. Too bad the kit is so expensive. Should come with the sport kit lol
The long travel kit is indeed overpriced.
So in summary, cut the shock limiter and use the softest (white) spring from Traxxas? Anything else? Are there some better options for adding aftermarket shocks?
With the softer springs, how does the ride height compare to a stock TRX4?
Man.. This is Legion Of Doom with spikes on..
So the way you got this result is just using the traxxas lift kit, soft springs, and removing the spacer on the shock itself?
What spring weight are those springs? I love that suspension setup
If you could give a little more detail on the tweaks you did on the kit and maybe about how a set of 1.9 wheels work would be greatly appreciated, great video!
So there is a 10mm spacer on the shock shafts that is removed to get the full travel.
A much softer spring set was used. This one is the stock springs from the Redcat Gen 8. Thee is room to raise and lower the vehicle.
1.9 wheels work just fine for sure. There is plenty of room for articulation. Ride height can be maintained to same same as stock if desired.
The servo horn and panhard link is adjusted so there's no collision at full travel.
The stock springs are very hard so there's no sag. And the 10mm spacer is there so 2.2 tires don't hit the wheel wells.
What did you have to do to servo horn an panhard link exactly an what spring rate
Servo horn is steel traxxas. Panhard link has a new mount included in lift kit. I’ll get the spring rate and length
@@RCReviewChannel I know all about the 2.2's rubbing the body mine does that with the shocks now something Ive lived with since I put the kit on along with axle spacers to try n give it a wider stance to try n keep from roll overs seemed to help but also rubs more when in an aggressive turn due to body lean.
I actually used a few spacers as well to get my pan hard clearance
@@RCReviewChannel
I have a new trx4 sport I'd like to start modding. I'm thinking this kit plus whatever don't springs he's using would be a good place to start? Parts list?
Is this with the servo mounted on the bottom side of servo drop mount like it's supposed to be? It doesn't take much to bottom out on the panhard bar. My trx4 is setup for 4 wheel Steering and the rear servo hits the passengers side top link very easy so I tried the servo on top side of the top mount. All that did was give me crazy bump steer.
So does the long travel suspension offer more of an advantage for the TRX to climb over rocks versus the overdrive transmission gearing for the front?
The overdrive/underdrive is better for climbing and steeper rocks. And it has no downside.
The long travel is good for very rough climbs. But the CG does get higher so it can tip over more.
How do you adjust ride height on the sport? I like the lift in the center but it doesn't look like or drive like yours.
@RCReveiws are these the redcat shocks that are 08001s part number
Can I ask for the full part list of this vehicle
🤘🤘🤘
I removed the springs that came with the lift kit, and put on the stock sport springs. they are a lot shorter but, adjusted them and it brought the height down a lot. running stock canyon trail 1.9 tires works great.
How did it go with the stock springs?
Which springs did you go with? I have the orange on the back and whites on the front. The body rolls sooooo much with the lift get on it.
I have a question about the "long travel" shocks. What size springs are they using, and can I get just the shock and springs
Yes super badass. You know nitro fuel can remove the paints so you can remove paints on windows area to make clear windows. Gonna be epic!
What size are those tires? Stock trx4 tires on 1.9 wheels?
What springs are you using. Red cat Gen 8?
Yes if the earth were 1/10 scale it would be the perfect RC Crawler in it's Category.
If you're someone who wants to try their realism hobby skill, The options are unbeatable.
There's room for the most daring of hobbyist to try their skill in RC
Some person out there is likely to make doors and hoods open and close with real windows, with their hobby blade and some time.
This is awesome!!! Can i use this kit on trx4 defender? Thanks
Yes
What size wheel did you use??
What motor and esc are you running?
Wat spring rates did u use on that rig?
Can you make a vid how to take off the limiters and what springs you’re using
Redcat Gen8 Springs. You can only get the springs with the whole shock assembly. To remove the limiter, take a pair of pliers (with some type of protection) and hold the shock shaft while unscrewing the rod end by hand. Slide the limiter off then screw the rod end back on. Make sure to search in youtube "TRX4 Shock Stickion". That mod is a must with both stock and the lift kit shocks.
How do you know it is Redcat Gen8 springs?
It's been mentioned on FB. I think he mentions it in another video or video comments as well. I just completed the mod 2 weeks ago.
Cool thanks for replying.... how do you like it?
@@bdp3502 the flex is insane. I put 10wt in though and hit local spot. Disappointed at how easy my rig rolled over on sidehills. Things I wasnt even doubting, it would roll/tip... Going to try 30wt and I'll post back!
Can a mod like this be applied to the Trx Sport?
I have been trying to decide for a week which truck I want ...I have been going back and forth but this video made up my mind!! Would you suggest this one or the sport model?
Sport for sure. Makes room in the wallet for upgrades!
RC Review I actually want to build the truck out of this video!! Awesome crawling performance with the lift kit and springs you used! I don’t think I have seen a 1/10 scale crawler do better in any video and I have been watching hundreds of them for several weeks.... which springs did you use? I’m not well versed in this part of RC as I am a plane and Drone guy originally , Need to get a truck now though!
What wheels are these? Brand and size?
How do you prevent the pan hard bar from hitting the front diff with the long arm kit? Mine hits the front diff preventing it from fully compressing having about 10mm left to go before maxing out of the left front shock.
Did you use the stock pan hard/shock mount?
I've got the same issue, any work around or is this just a down side to the lift kit setup?
@rcreview Looking to replicate this. What weight shock oil did you use? The oil from the kit or something else?
Did you dissassemble shocks to remove retainer? what springs did you use?
I just took the bottom plastic mount and the cylinder spacer slid out.
How do you get around the front panhard bar hitting the diff and servo when installed on defender, even with the 10mm bumpstop removed my diff huts the panhard with about 18mm travel still left
Same problem here (trx-4-kit). Are you using default servo and default servo horn? I installed srt 25kg waterproof servo(almost same height with default servo, 1mm taller).
Low center of gravity and tons of droop, just what we go for in real life on off-road rigs.
What tires
This was a goodone!
What tires is on your rig?
Proline hyrax
@@RCReviewChannel is it 1.9s or 2.2s
How much difference in flipping over on vertical climbs? Side hill?
Not too much since the ride height can be adjusted to be same as stock. Body weight has a much bigger effect.
I have been experimenting with springs on my lift kit since your first video. These are Gen 8 Stock springs you are using?
Yes!
@@RCReviewChannel Unfortunately, Redcat doesn't sell the springs alone yet. any other options for springs?
@@chadmelton6355 to the best of my knowledge, these are .22 spring rate or 'yellow springs' in Traxxas code. They are a little longer than stock TRX4 though.
Yellow is their softest. Softer than White.
@@RCReviewChannel Hmmm. The softest Traxxas makes for the long gts are .47 which are way to stiff. Ty for the help!
You sold me on this build. Are those 2.2's? its hard to tell the hyrax looks like a large tire?
We only use 1.9s. Large 1.9s for performance. 2.2's are too big and ruin Center of Gravity.
Thanks you know I thought they were but wasn’t certain.
@@RCReviewChannel we got a bit of a break here in Michigan with the weather. I did this to my trx4 sport. 1.9 hyrax and the incision plastic beadlocks. No added weight and it made everything easy with snow on the ground at that. The scx10's were no match with this long arm kit and awesome tires. Was to easy I had to look for other lines to give the truck a challenge.
You sold me I just built axial builder kit and i like it but I doint think it as good on rocks
We had 3 Axials and a Vanquish on this course and they don't come close. These rocks are axle hangers.
Do you run the od/ud mod in the bronco with the 2 speed and lift kit? Does it perform fine with 2 speed ?
No od/ud mod on this one which is almost all stock.
Od/Ud mod will work great for crawling. For high speed, it will be more stress with the wheel speed difference. Gears will be fine though since hardened steel.
RCReview Thank you so much! I absolutely love your videos! You are my go to for crawling. Keep up the good work!
So if I have a big budget to build a competition rock crawler should I go for a TRX sport and mod it to the limit or an Axial builders kit and mod that my question is which one shall I go for?
TRX4 for portals! Scx10 ii for lower CG and ultimate parts options
RC Review thank you for the tip
What traxxas part number is the body mounts for the trx 4 sport body I have the bronco and I want to put the sport body on it
Ojr Ringwald
8215 Traxxas part No , this pack has all the body mounts including the Sport Mounts 👍🏻
So can I use this for the txr sport?
Yes you sure can!
What size tires do you have on?
1.9 wheels. Tires are on the big side at 4.8 inch diameter.
Is the lift kit only available for the 12.3 inch wheelbase or do they make one for the 12.8 inch also?
The kit has two sets of rod ends, comes with the links set up for the shorter wheelbase installed. If you remove them and install the longer rod ends, it will work on the longer wheelbase.
Lane Waite thank you for the information.
@@mikebultema2536 No problem. Have fun!
I did exactly what you said.
have u realized that when your truck is fully stopped, then you start going foward you gonna see the back of the truck pushing the suspension down, the you go backwards it go up to normal again , then foward and start pushing down ... I dont know whats happening, does someone is having or did realized that???
I believe what is happening is the oil is too heavy for a light spring. So the spring is not able to return the shock on its own. Lighter shock oil will help/fix. It comes with a stock 35wt so maybe 20wt is better.
@@RCReviewChannel thank u for responding, but thats not the case, I have 35 oil, and the springs actually returns as long as I stop or reverse the car, then if I go foward it happens again, it seems something mechanic/physics, I did it 1000 times laid in the ground in front of it , whatched back and forth (very slow ) , I even tried to put the shorter links (just the 2 on top out of the 4), because it seemed that the whole axis was twisting on its own axis toward the front which was dropping pressure and pulling the suspension as a result...
the links changing didn't work , now I don't know what to do !
@@RCReviewChannel I made a video to show you, thank you in advance for the effort to help!!!
czcams.com/video/TWStbc2WiwQ/video.html
Okay anybody that wants to do this 19 mm spacers G made Wheels 1.9 Super Swamper tires Proline. THE BIG THING IS TRAXXAS PART # 8153 white Soft Spring long with 25 oil that helps plenty with droop lower level not tipping over and then put brass in the front axle for your turnbuckles and inner + outer. My blazer goes anywhere I point it
Would it be worth it to put it on the sport!
Yes, definitely. Can not unlock the diffs for bashing but can be good for crawling when set up like this
I guess it’s a secret what springs he used
White springs here bit.ly/2S8SsM0
Please lemme,know where you got Red rims and bigger tires
Those are Traxxas beadlocks.
@@RCReviewChannel nice i bought 2.2s gonna buy 1.9s still trying to figure out how you removed the limiters
IMO the sport is the only version of the TRX where it looks as if the lift kit belongs🤷🏻♂️
Good insight.
2.2s or 1.9s?
1.9s of course. 2.2s are not really very useful on the trail since it the Center of Gravity goes up to high.
💯👌👉👍👍👍👍
sir, what tires are these? brand?
Traxxas 2.2 canyon trail
you want to build me this thing and i just send you the money lol
Nvm 😅
Wheelbase doesnt suit that body
Trashx! Warranty is useless, and customer service uses rude language
What rate spring are you using in this video?
White springs by Traxxas. .22 I believe.
RC Review thank you can’t to get my sport that capable.
