Yukon Gear Positraction internals For 8.5in GM w/ 28 Spline Axles

If you're rebuilding the differential in your 1970-1996 GM vehicle, like a Chevrolet Caprice or Buick Regal, and it's equipped with an Eaton or Dura Grip positraction unit, this Yukon Gear & Axle spider gear kit is what you'll need. This kit contains all the essential internal gears and shafts that make your positraction unit work, allowing both rear wheels to spin at different speeds during turns while still providing power to both when traction is limited.

Yukon Gear & Axle uses well-built materials and proven manufacturing methods to ensure these spider gear kits last. This kit includes the side gears, pinion gears, cross pin shaft, roll pin, and thrust washers. It's specifically designed for GM 8.5-inch differentials that use 28-spline axles and are outfitted with Dura Grip positraction. Keep in mind that this kit does not include the clutch packs, which are a separate component of the positraction assembly.
