Roller Cam Button - .800

The Roller Cam Button – .800 from HOWARDS RACING COMPONENTS is a precision camshaft thrust button engineered for Small Block Chevy engines. This component manages camshaft end play and prevents forward movement during engine operation, a critical function in high-performance and street applications where valve train stability directly impacts reliability and power delivery. The .800-inch length accommodates standard Small Block Chevy cam journal diameters while the roller design minimizes friction and wear on the camshaft thrust surface.

Manufactured from steel with black oxide coating, this camshaft thrust button resists corrosion and provides long service life in both street and race environments. The roller construction allows the button to rotate with the camshaft rather than slide, reducing stress concentration points and heat generation during extended engine operation. This design is particularly valuable in high-RPM applications where camshaft movement and friction become limiting factors. The .800-inch specification ensures proper fit within Small Block Chevy engine blocks without modification, making installation straightforward for rebuilds and performance upgrades.

This thrust button is essential for anyone rebuilding a Small Block Chevy engine, whether for stock restoration, street performance, or racing applications. HOWARDS RACING COMPONENTS manufactures components for engine builders and enthusiasts who demand precision tolerances and reliable fit. The roller cam button prevents costly camshaft damage and valve train failures that can result from inadequate thrust management, making it a fundamental component in any serious engine rebuild.

Each order includes one roller cam button. Sold as an individual component for complete control over cam thrust management during engine assembly.
