Optimize Your GM 10-Bolt with Ratech Solid Spacers

The GM 10-bolt 8.5-inch rear end is a legendary platform, but it relies on factory crush sleeves that can fail under high-stress conditions. The Ratech Solid Pinion Spacer Kit is designed to replace these weak points, offering a robust, solid steel alternative. By utilizing the included precision shim pack, you can achieve the exact bearing preload required for maximum gear life and performance, eliminating the uncertainty associated with collapsible sleeves.

Performance Benefits

• Precise Preload Control: Use the included shims to set your bearing tension exactly to manufacturer specifications.
• Increased Reliability: Solid construction prevents the pinion from shifting under heavy acceleration or deceleration.
• Durable Steel Construction: Engineered for strength in high-performance street and track applications.
• Perfect Fit: Specifically machined for the GM 8.5-inch 10-bolt differential housing.

For enthusiasts building a GM 8.5-inch rear end, this kit is an essential upgrade. It simplifies the setup process and provides a level of stability that standard crush sleeves simply cannot match. Whether you are upgrading your drivetrain for drag racing or heavy-duty towing, the Ratech solid spacer ensures your gears stay in perfect alignment.
