Lifter Retainer for '87+ Chevrolet Small Block | CCM8105-LR

The COMP Cams Lifter Retainer (8105-LR) is a critical component for engines originally equipped with factory hydraulic roller camshafts. It sits in the lifter valley and provides the necessary tension to hold the lifter guides (dog bones) in place. This ensures that the roller lifters remain properly oriented on the camshaft lobes, preventing them from rotating and causing catastrophic engine failure.

• OEM Replacement: Designed to be a direct replacement for the factory GM lifter retainer, making it ideal for engine refreshes or performance builds using the stock-style roller setup.
• Essential for Roller Conversions: A vital part of a complete Hydraulic Roller Installation Kit, allowing older blocks that have been machined to accept factory-style lifters to function correctly.
• Durable Steel Construction: Made from high-quality spring steel to maintain consistent downward pressure on the lifter guides across thousands of heat cycles.
• V8 & V6 Compatibility: While primarily used for Small Block Chevy 305 and 350 engines, this retainer design is also used in GM 4.3L V6 applications.
