Description
This differential case only fits 8-5/8 (8.6″) 10 bolts with 30 spline axles for 1999 and newer C/K trucks or 2000 and newer SUVs
This is the Heavy Duty “708” version, it has 2.5 times the clutch apply area as a normal 8.6 G80.
When we rebuild a GM G80 heavy duty gov-lock 8.6 posi differential, we completely disassemble each carrier, clean all the components and then all the parts are inspected.
Once disassembled, we check for the following:
- Broken ramp plate
- 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
Worn out parts are replaced with parts that have plenty of life left in them.
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.
