C6 Z06 Differential Bearing Kit 06-13 Corvette Z06 / ZR1

C6 Z06 Differential Bearing Kit 06-13 Corvette Z06 / ZR1 – Complete Rebuild Solution

As the sole supplier of the C6 Z06 differential bearing kit, we’ve done the hard work of sourcing every critical bearing into one convenient, application-specific kit — including the notoriously difficult-to-find pinion bearings. This is the only kit built exclusively for your Z06 differential.

What’s Included

• Inner & Outer Pinion Bearings/Races (NP564647 / NP068900) – Nearly impossible to source elsewhere, we’ve got them. These support the pinion gear and are a leading cause of gear failure when worn. Replacing these during any rebuild is essential.
• Carrier Bearings/Races (387A / 382A) – Maintain proper gear mesh and backlash for smooth, consistent power delivery to both rear wheels.
• Axle Support Bushing – GM cross reference 89059220. Critical for precise axle movement and reducing side-load stress on differential internals.

Fitment

• 06-13 Corvette Z06
• 09-13 Corvette ZR1

Why Rebuild Now?

Common warning signs of worn differential bearings include speed-dependent whining or humming, vibration under load, clunking during acceleration or deceleration, and drivetrain slop. Catching it early prevents far more costly damage to your ring and pinion, and carrier components.

All bearings and races meet or exceed OEM specifications for reliable street or performance use.

This kit does NOT include seals or O-rings. The O-ring / seal kit is sold separately. See link below
