DRP Performance 007-105903 GM 12 Bolt Pinion Bearing Spacer Truck Steel

The DRP Performance 007-105903 is a precision-engineered pinion bearing spacer designed specifically for GM 12-bolt truck rear axles. This high-quality steel spacer replaces the factory crush sleeve with an adjustable design that allows for precise pinion bearing preload adjustment to within .0005 inches, ensuring optimal differential performance and longevity.

Key Features:

• Replaces factory crush sleeve for repeatable, accurate pinion bearing preload setup
• Adjustable to .0005 inch tolerance for precision bearing preload control
• Constructed from durable steel with black powder coat finish
• 2.133 inch thickness designed for GM 12-bolt truck applications
• Reduces pinion bearing operating temperatures
• Extends ring and pinion gear life through proper bearing preload maintenance
• Improves overall differential performance and efficiency

This adjustable bearing spacer is an essential upgrade for racers and performance enthusiasts who rebuild their differentials multiple times, as it eliminates the need to replace crush sleeves with each rebuild. The precision adjustability ensures optimal bearing preload, which translates to reduced wear, lower operating temperatures, and maximum power transfer through the drivetrain.
