COMP Cams Retainer Lightweight Tool Stl 1.5

Starting with a 10-degree angle and CNC-machined from high-grade tool steel, these retainers from COMP Cams offer a notable advantage in valve train performance. They are designed to be approximately 33% lighter than conventional chromemoly steel retainers, bringing them close to the weight of titanium without the associated cost. This reduced mass helps the valve train operate more efficiently, especially at higher RPMs.

The tool steel construction provides exceptional strength and wear resistance, making these retainers well-suited for demanding race applications. They are Spintron-tested to ensure they can handle extreme engine speeds consistently. These retainers are engineered to fit all stem sizes and work with valve springs that have an outside diameter between 1.500 and 1.550 inches.

This part fits a wide range of Ford and Mercury vehicles from the early 1970s through the early 1980s, including models like the Ford Mustang, Mercury Cougar, and Ford F-150. They are a solid option for anyone rebuilding or modifying their engine's valve train for improved performance and durability.
