Description
This G80 differential only fits 8.6 or 8-5/8 10 bolts with 30 spline axles for 1999 and newer C/K trucks or 2000 and newer SUVs
We build these to order; new clutches are optional. See our information page for more information.
Units with new clutches are built to order, keep in mind that with these units there may be a 1-2 day shipping delay.
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 differential carrier and set the internal end play back to within GM specifications.
We remove the old side bearings and install new Timken side bearings; a new set of bearing races is included.
This 8.6″locking differential comes with a new GM cross shaft retaining bolt and will arrive carefully packaged – ready for you to install.
