What rear setups are you guys running?

[97stanger]

The only stock part left on my car is the rear...go figure

As of right now all I have are 4.10s and a trickflow girdle
stock axles/diff

My tire/rim setup in the rear is 15x9 weld prostars wrapped in 275/60/15 MT ET Street Radials

What rear diff do you guys think would support 600hp range, street car with some track trips, and radials?

I pretty much have it narrowed down to Moser 31 spline axles

I have an '03 Cobra diff with carbon fiber clutch plates and moser 31 spline axles, so far so good but I'm not sure on it's HP limit.

go w/ the carbon trac loc internals and the revised steel placement order, replace the s spring while youre there.

that much HP you're probably going to want to step down to a 3.73 or even a 3.55 depending on what you're intent is. Stock ford carriers will handle that hp no problem
If you go the c clip eliminator route. I would look into doing 9" ends since they seal up better.

I have been reading some pretty good reviews on the trac loc w/ carbon clutches, just cant seem to find its hp limits. I'm running 4.10's because of the auto, 28" tall tire which completely kills the gear.
American muscle sells the trac loc w/ carbon clutches for pretty cheap, are you saying I would have to mod that some more?
Thanks guys, I'm not too caught up on rear diffs

If you dont go with that get a Locker diff. man i love that thing :headbang:

3.73's, stock diff/axles, diff girdle, 295/35-18's on 18x8.5" Konigs

(I have a 31-spline diff, 31 spline moser axles, a 8.8 housing brace and 3.55's in boxes waiting on time to install)

 

[DropTopPony]

Auburn Pro (must add friction modifier or noisy)
31 Spline Mosers
3.73 FRPP

I'd like to get my axle tubes welded before I put the blower on too.

after doing a decent amount of research I pretty much have it down to 2 diff's:
detroit locker or detroit truetrac
seems as though the locker is great for straightaways, but noisy as can be and going around turns can be a problem
the truetrac seems to be the best of both worlds
