01 bullit posi fit?

sniperrider · October 2nd, 2008, 02:28 PM

got a 90 lx and a 01 bullit posi unit with 20 thous. miles on it i checked the splines on the axles from a ranger i had laying around from 5 lug conversion and they slide right in and it looks legit. i want to leave my 4 lug assembly in this car and put the 01 unit in. has anyone done this? and will it work?

Hunt_chevs · October 2nd, 2008, 02:29 PM

you mean only put the carrier in and not the axles?

sniperrider · October 2nd, 2008, 02:32 PM

yea the axles are like a inch too long on each side i looked into that just the carrier and leave the 4 lug axles

Hunt_chevs · October 2nd, 2008, 02:35 PM

i believe they are diff splines

Hunt_chevs · October 2nd, 2008, 02:36 PM

you would need the axles..

sniperrider · October 2nd, 2008, 02:36 PM

i have 5 lug axles that slide in perfect to the unit which are 28 spline what are stock 4 lug axles

Smirnoff · October 2nd, 2008, 03:30 PM

i thought the stockers were 28 spline also, slide one in and see if she goes or just count them

sniperrider · October 2nd, 2008, 04:12 PM

i will have to do that cause the bullit posi unit is 28 spline and so is the 5 lug cnversion axle that also slides into my stock posi unit so it looks flawless i was just checking to see if anyone has tried this before

The only 8.8 axle that has 31-spline axle shafts came out of the trucks, like F-150's and Bronco's. All others are 28 spline.

And Mustangs don't have "Posi" rear ends...they have TracLok.

yea i know lol thanks for correcting me so i should be fine putting the 01 "TRACLOK" jk in?

lol...wasn't so much of a correction as it was meant to be funny. I get a kick out of doing that when a Camaro owner asks if my car has a "posi" rear end.

Anyways, yeah, you should be fine, so long as you use the same axles. The differentials are a direct swap.
