Yukon Gear Master Overhaul Kit For GM 8.5in Diff For Oldsmobile 442 and Cutlass. 28 Spline

When you're rebuilding the differential on your 1965-1981 Pontiac Catalina, Oldsmobile 442, or Cutlass, having all the right parts in one box makes the job much smoother. This master overhaul kit from Yukon Gear & Axle is designed specifically for the GM 8.5-inch differential with 28-spline axles, giving you a complete set of components to get the job done right.

Inside this kit, you'll find everything needed for a thorough rebuild, including carrier bearings and races, pinion bearings and races, a new pinion seal, and a complete shim kit for precise gear setup. It also comes with essential small parts like ring gear bolts, a pinion nut, crush sleeve, thread locker, marking compound with a brush, and silicone sealant. Yukon specifies Timken bearings and races, known for their durability, along with high-quality seals and other small parts, ensuring a well-built and reliable repair.

It's worth noting that some early OEM gears used right-hand thread ring gear bolts. This kit includes left-hand thread bolts, which are compatible with later OEM and all aftermarket gears. If your specific application requires the older right-hand thread bolts, you'll need to order those separately.
