Use a girdle w/the pinion cap brace studs. Helps to stiffen the housing by eliminating any deflection and the cap studs help keep the pinion from "walking".

Other than that.... not too much you can do other than stronger axles but they aren't usually what fails. Nine times out of ten the ring gear scatters taking the pinion and sometimes carrier w/it.

If you're going to launch the car hard with the ten bolt/7.5" rear, I wouldn't use much more than a drag radial, and try to pre-load the rear at the line before launch to take out the slack between the ring/pinion gears. Also when launching, don't just drop the clutch, try to feather it(all be it quickly)out of the hole..... seems to help 'em last a bit longer.

One other thing.... the stock suspension components are notorious for wheel hop which will suck the life out of the stock rear at a faster rate. Invest in some adjustable LCA's, and LCA relocation brackets if you're getting any significant wheel hop.
