hey guys,
i have an 8.8" rearend with 3.73 gears and an open differential, but ive been considering upgrading to a limited slip differential. i was looking in the summit webpage and found this: t-lock LS . to upgrade to a LS, will i need any other parts? Thanks!

 

I'm not shure on thins, but who ever knows, will this void the warrenty, I think it would, but wasn shure. Will this allow both tires to spin at the same time.

 

yes, it will allow both wheels to spin at the same time. as far as warranty, i dont know because my warranty ended a while ago .

 

That is a stock ford differential like comes factory in many trucks. I would start searching junk yards for a used one. I bought one out of a 94 Explorer and put in my 92 F150 and it only cost $75. (and it only had 45,000 miles on it). All 5.0 mustangs from 86 and up had 8.8 rear ends with that type of limited slip. I dont know if the carriers are the same, but I know there are plenty of those around.

 

When it comes to diff parts,i would spring for brand new stuff,ie bearings,shims,gears,and lockers-L/S.
It will be worth it in the long run.

Try looking into Power-lok diff............it's more of a off-road L/S,but hear it's the toughest out there.

 

i feel the same way, i like having new parts. is the power-lok fully streetable? i want something streetable because my truck is in the street 80% of the time and i take corners like i was at the last turn of the indy 500 , so i dont want to have problems with fishtailing and things like that around fast corners. ive also been hearing a lot about the powertrax differentials, locker power but fully streetable. anyone heard anything about these?

 

Power-lok is a good product,keep in mind it's still a L/S not a locker......so u wont have any problems with turning.
About the Power trax,i'm not too sure but i've heard their pretty good.
