Detailed Description

This differential bearing kit is built for rear differential rebuilds that require accurate bearing fit and dependable load handling. The kit includes tapered bearings with multiple cone and race dimensions listed for application matching, along with bearing races and related setup components. It is intended for vehicles using a 9.5-inch ring gear and a 12-bolt ring gear pattern, with a 30-spline pinion specification shown in the product data.

Vehicle coverage includes rear applications such as Chevrolet C1500, Chevrolet K1500, GMC C1500, GMC K1500, Chevrolet G20, GMC G2500, and related trucks, vans, and Suburban models listed in the fitment data.

What It Helps Fix

• Excess bearing noise from worn differential bearings
• Gear lash issues caused by bearing wear or poor bearing fit
• Rough differential operation during acceleration or deceleration
• Leak concerns related to worn seals during a differential rebuild
• Setup delays when sourcing bearings, races, shims, and seals individually

Installation Notes and Tips

Verify the rear axle configuration, ring gear diameter, and bearing dimensions before ordering. Differential setup requires careful measurement of preload, backlash, and gear pattern, so compare the included bearing sizes and race dimensions against the original components. Use the marking compound during setup to confirm gear contact pattern before final assembly.
