Re: help me reinforce my rear
other than that, upgrade to 28 spline axles. the weak link is still the ring and pinion, its only a matter of time before something happens.

A T/A PErformance aluminum cover can help. They are not cheap or free, but they do strengthen the housing and bearing caps. 28 spline axles and an Eaton piosi will also help, but also not cheap or free.

Yea, nothing is cheap or free, but the aluminum girdle (the cover) is the main point.
A better posi, aftermarket 28 spline axles... those help a lot.

Re: help me reinforce my rear
The only things that I did to my diff was weld the axle tubes and used a TA girdle.
Best 60ft was 1.52
Best et was 11.00 @ 125mph.
That was a stock diff otherwise(gm 10bolt, 7.625) with a 700r4
BTW, I blew the diff on the last pass on the last race of the year.
165hp shot of nitrous off the line was just too much.
I dyno'd my car and it was 377hp to the wheels(that was na)

Re: help me reinforce my rear
I tried sliding 28 spline axles in a 26 spline rear, after changing the spider gears. No posi involved at that time. Didn't want to undo the caps. Anyway, doesn't work. You hafta change the carrier. If your car has drum brakes, you can just get a later axle. Try a 90-92 V6 automatic car for the 28 spline axles with a 3.42:1, 7.625" setup, then spend $350 for a conversion locker. Or not. Worked well for me.
