Limited Slip Differentials

SuperItalian · 06-12-2007, 11:43 AM

I'm trying to find a good limited slip differential for a 7.5" rear end. I'm told Auburn and Eaton are very good quality. I just cant seem to find any that arent for the 8.8" rear end. The regular trac-lok just isnt going to be strong enough for the application I am doing. If it helps, this will be my setup:

4.2 Stroker, NA
3.73 rear gears
Stage 2+ clutch/Aluminum flywheel

Thanks.

if the frpp one isnt going to be strong enough, maybe you should just switch to an 8.8 rear...

I dont know if the Ford Racing T-Lok Differential would be enough. I think it would. I'm not going to be doing anything race heavy. Just as a daily driver.

Well then it looks like I am going to have to go to a yard and see if I cant get an 8.8 out of a GT. Thanks guys :-)

I dotn think a 9'' rear end bolts right it. but if it does...yeah.

I have been told by a number of others that I dont need to change out the rear end. If I get a Detroit Truetrac LSD, I should be fine. Any opinions?

if you plan on making serious HP, do not bother with the 7.5, for many reasons. one being there are sooo many more options for an 8.8. you get soo many more choices in the brands of gears and t-loks w/the 8.8. and since ur sticking w/the 6cyl. still the 8.8 should handle w/e you can throw at it...if tealbeast ever comes back ya could ask him what he's got in his TT sixxer, i believe it's an 8.8, not positive tho.
