Open diff to lsd

[Jeff Donison]

I have a 17 sport with open diffs 3.21 gearing I wanna switch it out for some sort of lsd. What is the best route to go with this part numbers would help. When switched does in work in series with the existing traction control and such do I need any other parts as well?

14 express. I went from open to eaton trutrac. No issues.

15 Express. I went from open to OEM lsd. No issues, nothing else needed.

2014 Eaton tru-trac will outlast OEM anytime,OEM has clutch’s that wear over time

Traction control natively plays well with limited slip differentials, no changes needed.

You'll want new carrier bearings & races.
LubeLocker gasket is the best way to seal the cover.

I put OEM in mine years ago. I view the OEM as light duty. Mine works fine.

Having said that, if I Wes t do it again, I’d spend a little more and put in a Tru Trac. First class is always a good choice.

Bumping this thread. I have a 2014 8spd and need a diff rebuild. Im looking to put in an LSD but the shop is saying i will have a ton of issues with the 8spd not being programmed for it. Can anyone confirm?

Find a better shop. Or DIY as gear change are easy as pie. and I see in your sig line that you have a custom tune already so just ask Jay for advise as you should have custom trans tuning already.

as for LSD , trutrac is the only way to go. OEM LSD is junk on a good day !

 

[Daw14]

They are mistaken.

Thanks for getting back so fast guys! My diff needs a complete rebuild except the ring and pinion. Unfortunately Jay cant tune my trans since its locked out on my truck and no way to get in unless i get a new programmer. I do nothing but plow with this truck and make short trips now i just want it to last as long as It can at this point. 3.92's plus, tune, plus rain is a nightmere tho so i dont need a fancy lsd or locker i just need traction.

As others have started, have the TrueTrac LSD installed, then you won't have to worry about the differential and you'll get better traction as power will go to both rear wheels.
If the shop your dealing with is telling you the transmission needs to be programmed for a LSD, they're FoS .. go find a better shop

Finally got rid of my one wheel peel, and got the limited slip so I can hook better and do big burnouts!Subscribe to my channel for videos of my 1997 Ford Ta...

Think about it. The trans doesn't know or care if the diff is open, lsd, or solid lock, all it knows is there's a load to be driven. As others have said, if the shop tells you it's an issue, drive away FAST. Not too fast though, you could spin 1 wheel since you still have an open diff.
