blk89lx

alright im going to do 3:73's in my auto and before i get them put in i was thinking about a posi and 31 spline axles. would this be any good or can i do fine without them? the only reason i dont want to do the posi is because its alot of $.

Posi just means limited slip....if it's an 8.8 rearend its has something called T-lock, allows both wheels to turn until u take a corner..I have a 7.5 in my car now with the 1 wheel peel and it sucks, im swapping it out for an 8.8 with T-Lock....200hp to 1 wheel..or 200hp to 2 wheels!!!

why put a Posi in the rear when you have a Traction Lok? you can use a explorer traction lok its 31spline



also itwould be benefical to do a search and read a few posts before posting a topic that has been coverd a few things this week

Well how much power are you pushing or how much do you plan on pushing? I mean you do have a traction lock stock in the 89 so you do have posi. I am guessing you mean an upgrade one such as auburn or eaton. Really depends on what you want to do with the car.
