Each BET Performance rebuilt carrier is totally disassembled, and cleaned, then we inspect all the parts. Once disassembled, we check for the following:

  • Broken cam gear
  • Stripped governor teeth
  • Worn out case holes
  • Worn out clutch packs
  • Spun bearing journals
  • Worn or galled cross shaft and pitted side or spider gears

Next, we carefully re-assemble the G80 8.6″ gov-lock differential carrier and set the internal end play back to within GM specifications.

We remove the old side bearings and install a new side bearing races and a new set of bearings.

This G80 8.6″ gov-lock posi differential comes with a new GM cross shaft lock bolt, and will arrive carefully packaged and ready for you to install.
