Upgrade to a Solid Pinion Spacer

Eliminate the inconsistencies of a standard crush sleeve with the Ratech Solid Pinion Spacer. Designed specifically for the GM 8.875-inch rear end, this solid spacer provides a more stable and reliable pinion bearing preload. Unlike crush sleeves, which can compress further under extreme load, a solid spacer maintains its integrity, ensuring your pinion gear stays perfectly aligned during aggressive driving and high-torque applications.

Technical Advantages

  • Replaces standard crush sleeve for superior stability
  • Includes precision shims for exact preload adjustment
  • Constructed from high-strength steel
  • Ideal for high-performance and racing applications
  • Ensures consistent pinion depth under load

The solid spacer is a preferred upgrade for anyone serious about drivetrain performance. By removing the "give" found in traditional crush sleeves, you protect your ring and pinion gears from the damage caused by pinion deflection. This kit comes complete with a shim pack, allowing you to fine-tune your bearing preload to the exact specifications required for your build. Whether you are building a drag strip warrior or a high-horsepower street car, the Ratech Solid Pinion Spacer is an essential component for long-term reliability. Improve your vehicle's drivetrain efficiency and durability today. For expert advice and the best selection of performance parts, look no further than GGCRACING.
