Moser Engineering Rear End

If your making serious horsepower, your stock axle is not going to hold up. Moser Engineering has a complete bolt in kit for the 77-96 B bodys. Its a Ford 9in carrier, they dont seem to have Chevy 12 bolts for the B Bodys. They also have what they call "muscle pak" this is a completely assembled ready to bolt it, with brakes included. The link below just takes you to the regular 9 inch rear for you to customize it. http://www.moserengineering.com/complete-rear-end-assemblies/9/9-housing-axle-package-inch-part-number.html

Bought Moser's Ford 9" with disc brakes for my LS-swapped '79 Delta 88.

The gears were set up wrong, the brake calipers leaked, the rotors were chintzy, and the axles and tubes were juuuuust weird enough to not work well with parts from other vendors. I'd go a different direction if I had it to do over again.
