FAQ
What differential does this kit fit?This kit fits the 8.2in Buick/Oldsmobile/Pontiac differential with 28-spline axles.
What is included in this kit?This kit includes the positraction spider gear internals and related small parts for a complete rebuild.
Is this for an open differential or positraction unit?This kit is designed for positraction (limited-slip) differentials, not open differentials.
Is professional installation recommended?Yes. Differential internals replacement requires carrier disassembly and should be performed by a qualified technician.
Why replace positraction internals?Worn positraction internals can cause reduced traction performance, noise, or chatter during turns; replacing them restores proper operation.
Does this kit include carrier bearings?No, this kit focuses on the positraction internals; bearings should be ordered separately if needed.
Can this kit be used with a new ring and pinion set?Yes, this kit is commonly installed during a full differential rebuild alongside new gears.
Do I need to confirm fitment before ordering?Yes. Confirm your exact vehicle, differential, and spline count before ordering.
Installation Instructions
- Remove the differential cover and carrier assembly.
- Disassemble the carrier and remove the worn positraction internals.
