8.5 10 Bolt

Answer 1

If it's a 7.5" 10 bolt, and your putting any power down then I wouldnt change a thing in it.. Just wasting your money.. I broke 2 7.5" rears just running 11's in the 1/4 mile..

Go with a 12 bolt, or 9"

Now if it's a 8.5" 10 bolt, 12 bolt or you just want to build the 7.5" then...

Moser, yukon, strange, etc axles, Timkin bearings through out the rear end.. TA alum support cover with the pre load bolts.

Have the axle tubes welded to the center.

Good gear oil like red line, RP, amsoil, etc.
