I have a 91 auto stock rearend and I was looking to getting some 4.10 gears and 28 spline axles. Will I benefit from this kit or do you guys sell a 28 spline diff? And also, with this kit, would I get the benefits of a "posi" rearend instead of the one wheel peel I'm doing now?
Your car is one wheel peeling because the factory traction-lok is worn out. (fairly common issue) This is the kit to rebuild that unit. Much tougher than stock. I rebuilt the rearend in my 98 GT. Installed FFRP 3.73 and this kit. Made a huge difference. No more one wheel peel.
