Mechanics and gearheads working on GM differentials, this Yukon bearing kit has everything you need except the shims. Perfect for shops or experienced DIYers who already have shims on hand and want to save some money compared to full master overhaul kits. The kit includes quality Timken bearings and races - both carrier and pinion - along with pinion seal, crush sleeve (if your application needs it), oil baffles and slingers where applicable, plus marking compound and brush for setting your gear pattern. Yukon does their homework on each application to make sure you get all the correct parts for your specific GM/Chevrolet passenger car differential installation. The Timken components are known for their reliability and longevity, which is crucial for differential work where failure can be catastrophic. This is definitely a job for someone who knows what they're doing - setting up differential gears requires precision and the right tools. But if you're tackling a ring and pinion installation or rebuilding a differential, having all the bearing components in one kit from a reputable brand like Yukon makes the job much smoother. Seriously, if you're doing differential work and need quality bearings without paying for shims you don't need, this kit delivers the essential components from a brand that off-roaders and mechanics have trusted for years.
