installation kits
A typical installation kit includes:
Pinion Bearings – Support the pinion gear and allow it to rotate smoothly under heavy loads.Carrier Bearings – Support the differential carrier and maintain proper gear alignment.Pinion Bearing Races – Matched races for the new pinion bearings.Carrier Bearing Races – Races for the carrier bearings.Pinion Seal – Prevents gear oil from leaking where the driveshaft enters the differential.Crush Sleeve or Pinion Shims – Used to achieve the correct pinion bearing preload, depending on the axle design.Pinion Nut – A new locking nut used to properly secure the pinion yoke.Pinion Shims – Used to set the correct pinion gear depth for proper gear tooth contact.Carrier Shims or Adjusters – Used to set bearing preload and backlash between the ring and pinion gears.Ring Gear Bolts – New high-strength bolts to securely fasten the ring gear to the differential carrier (included in many kits).Gear Marking Compound – Used to check the tooth contact pattern and verify proper gear setup.Thread Locker – Helps prevent critical fasteners from loosening over time.Gaskets or RTV Sealant – Used to create a leak-free seal on the differential cover.Why Use an Installation Kit?
Whenever a ring and pinion is replaced, it's recommended to install new bearings, seals, and related hardware rather than reusing old components. New parts ensure proper preload, gear mesh, and reliability while helping prevent leaks, noise, and premature gear failure. A quality installation kit provides everything needed to complete the job correctly the first time.
