- Ken (subscriber) made the decision to protect the drive train of his lifted 2017 Ram 1500 w/ 37" tires. He took his Ram to Chester Country Transmissions for a 3.92 gear swap. Steve turns the video over to Andy & Pete to film the install & unboxing. As always they provide tips & detailed info along the way. The install comes to an abrupt end after discovering a serious problem.

Damn. I’m glad I paid the $95 and got 3.92 from the factory.
Important things to remember when buying a new truck.
Glad I got 4.10 in my 2500
Good job keeping this guy in business, hopefully he brings you enough Amsoil sales.
I have the 392 in my 2019 ram I love it
Great video, learned a lot and really wishing l had got the 3.92 stock....
Thank you
Wow i have a 17 and seeing the 392s for sale for a 17 i figured they would bolt right in, I guess I have to get a new front carrier, thanks for the info guys
I am seriously considering doing this swap. I have a 2019 ram with 3.21 in it. What is the final price tag for this?
I lifted the truck and put 3.55 in mine, works great
I have stock 3.92 with 37's. It's not enough. You still have problems on the hwy as the truck will not want to go to 8th gear. And of course the loss of torque from stock tire dia sucks! You can go to 4.56 in front and rear! For the rear I'm installing a TruTrac LSD. For this you need a drivers side axle to be installed on to passenger side. 4.56 will fit in the front diff! Yes you need to install a new carrier as the ring is welded to the existing. The only major problem is you need to have a custom pinion made and that's definitely doable!
Custom pinion? I guess anything can be done...
How much did the shop charge you to replace the whole front differential axle assembly. Had my Jeep in a shop and they quoted 2800 for a new front differential/ axle assembly
So how much does the complete front differential run?
Haven't did diffs in a long time. But that's just crazy to change the Gear ratio you have to change the whole front diff rather then just the gears ridiculous thx for the info
Word of advice for any that has had a wobble in the front end of a ram, that will never go away, different wheels and tires, shocks, alignments and Shocks, front hub assembly…
I bought my 2014 with 38k on it and cause that o ring was missing, the stub shafts and cv axles were rusted just enough… Multiple shops and warranties claims nobody could ever figure it out even when I ask about those, they said no they are good.
Well I finally at 176k decided to just replace them,it turned into me replacing everything. “since I was in there” Well when trying all the methods of getting the cv shafts of the dif.. I had to remove the part of the diff that the shafts connect to cause the passenger side was seized on! Vise hammer and flat punchs it would not come off… Had to soak it overnight,then come back with a bigger hammer and got it off..
Yup both shafts were eaten away from rust causing just a little bit of tolerance issues. I had to pull that whole part apart to replace the passenger side input shaft So I just replaced everything else in there at the same time… For the first time ever I have owned this truck it rides smooth, no more center counsel shake
I'm wondering what kind of extension and socket was he using on the back differential.. i was planning on doing it myself, it definitely doesn't look hard... But it doesn't look easy too tho Lol
I ordered 4.30 gear ratio from the factory in my 2020 1500 night edition
When did a 4.30 become an option for a ram 1500?
@@wd9581 as far as I know its max a 3.92 and the 2500 is a 4.10. 3500 has a 4.30 I think
My has 3.92 from factory I just has the hole front rebuild because everything was sized 🙃 I mean axles hub bolts brakes upper and lower ball joint the driver side axles was so sized it had to be cut out almost had to buy new spindles it a fun job lol
I have a 2019 ram 1500 5.7liter with a 3.21 rear wheel ratio, can it be upgraded and is it worth upgrading to maybe a 3.92 ?
I’m thinking of doing the same, I have a rwd so I would think it shouldn’t be too bad. Let me know how it goes for you because I have a few other things I’m gonna do before worrying about the rear end like headers, tune, etc…
The ring gear is lazer welded to the carrier.
What company did you find the gear ratio for the new ram need to change them out 392 to 355 better gas mileage?
Can I ask where that front axle was purchased? I have a 2021 ram 1500 4x4 and want 392s. Can't seem to find one AT ALL
That totally sucks. But you are right, something will inevitably go wrong.
Crap happens occasionally
Ram 02 4x4 4.7 tiene pasos 3.55 y tiene llantas 33/12.50/17 será mejor el paso 3.92 ?
Do you think a 3.7 would fit on a CHARGER RT 07 RWD ?
Hey man! Im new to this and need help! I want to change my ram 1500 3.21 diff to a 3.92. Again idk but do i need both front and rear 3.92 diff to do it right? Any other part i need to change to handle the new change? Thank you man
Yes, you'll definitely need to do both front & rear differentials to do it right. I would contact a reputable shop like Chester County Transmissions. www.chestercountytransmissions.com/
Good video.
But couldnt you find a few more background music clips to play? Sometimes less is more.
I have an 02 ram 1500 4x4. If I upgrade the rear to 3:92, what front end do I need? Obviously have to change front when you change rear end ratio.
Same ratio. They have to match.
So you have to get a new rear end?....that thread is machined into it looked like..
I know this video is older but did you guys have to Flash the ECU after the heat swap?
I have 37x12.50 tires on my 2 WD Dodge ram 1500! Is 3.92 enough!? I wanted to drive better and save on gas!! What do you recommend?
Great Vid, looking forward to the outcome.
Thanks Mike!
I have a 2014 dodge am 4x4 I wanna do some 392 up front people told me that it’s a 9.25 or a 8.25 or a 8.0 any help on what it could be ?
Moes performance sells 392 and 410 to bolt right in
No they don't. Not for the front.
Also called a thread protector
I've heard rumors you have to edit software to recognize the 3.92. Can you confirm or deny? I feel like that shouldnt be necessary
I believe you do have to update that parameter in the ECU. Most shops have the proper tool to do it.
Do still have 355 gear?
After installing a different gear ratio to a truck specifically a ram, is there any tuning/programming needed since the pcm is set to shift at the rpm’s for the original gears?
Following just put in 410 front and back
What were you guys measuring at 12:19? I'm thinking to change from 3.21 to 3.92 of my 2014 ram 1500 4x4.
Backlash
Where did you get the front unit from?
I have a 2019 Ram (new style) with 3.21 gears. I’m considering swapping in 3.92 for towing a camper. Would my truck be just as difficult to do?
If you have never done one, 100% yes, extremely difficult & costly if it's not done right.
@@BEASTProjects hi I have a 2019 classic 4x4 with the 5.7 l hemi and would like to swap over to 392 gears. Is there any difference in having a 4x4?
Since you swapped the entire front axle, ,,,, couldn't you take one side apart and simply slide the other half shaft out and then back in with the nee axle without taking the 2nd side apart????
We tried, unfortunately it didn't clear the carrier, so both sides had to come completely out.
Jesus that is just junk. Same crap is in the GM stuff. With what these trucks cost they should be putting a Hell of a Lot More quality into them.
Im doing a 3.92 swap in my 17 ram to. Where did you get the kit? I checked their website and there isnt like a catalog. And what is the difference between the 9.25 and 9.25 ZF

I have 3.21 gears and 35s and it's terrible lol how much was the cost on front diff ? What would you recommend? I don't give a shit about mpg.
If you’re staying with 35’s, 4.10’s.
I just bought a 1500 with 3.92 gears and I hate it, horrible fuel mileage, I don’t get it, why is the 3.92 desirable, are you going to tow 11000 lbs with a 1500 ?
There is a much much easier way of doing this !! Buy a truck that's already got the 3.92 in it !!!
Is he putting a locker back in it?
Stay tuned, another video coming on Friday at 5pm.
Is this a DS or DT?
DS body style. The front sway bar is on the forward side of the cross member
😢
Looks like that truck needs some more brake line in the rear.
Yup
Why does that guy look like hawk eye from avengers?
So basically the dealership lied and said that I had to replace the whole front axle?
Uhh you do.
I got 3.55's on my 1500 ram on 33x12.50. Do u think the 3.92's be better for mpgs on the highway
Doubtful
Can u make a suggestion? Or I shouldn't bother?
I wouldn’t bother unless you were going to 35’s or higher.
Get an electric truck if your worried about mileage
It will be worse. For better MPG you get 3.21s
Not a good build at all........noticed that this truck is not setup for off road anyway missing a ton of stuff starting with basic skid plates.
I think the SERIOUS PROBLEM discovered is that it was IFS...
First like 👍🏻
Thanks Mike! Happy Holidays!
BEAST Projects thank you 😉 happy holidays to the whole beast family 👋🏻
Any of you complaining about the back ground music.... they had to cover up the Miley virus bullshit we were listening too. People would start selling their dodges when they find out their mechanic is a puss ;) lol
Jk I know how it is radio is best, no sense in getting your phone dirty trying to find the right shuffle of slip knot and Tupac
Glad I really don't care about this stuff..I watched the vid any way..looks like a waste of money
turn off the music
This is a huge deal breaker for me. I really wanted one of these rams too that really sucks
Just find one that already has 3.92’s
Send it. Who cares?
