Roller Cam Button - .800

The Roller Cam Button – .800 from HOWARDS RACING COMPONENTS is a precision-engineered component designed for serious performance engine builders and drag racing enthusiasts who demand reliability under extreme valve train stress. This compact yet critical part serves as a load-bearing interface between your camshaft and valve lifter assembly, ensuring consistent valve actuation across high-RPM operating conditions.

Manufactured from a durable steel alloy, this roller cam button is capable of withstanding the repetitive shock loads and contact pressures generated by aggressive camshaft profiles at sustained 7,000+ RPM operation. The .800-inch diameter specification indicates this button's precise bore size, engineered to match OEM or performance roller lifter designs with minimal clearance tolerance.

Race teams, engine machine shops, and restoration specialists working with roller lifter systems benefit most from this OEM-quality replacement part, particularly when assembling complete bottlenecks in high-horsepower applications. The roller cam button's reduced contact surface area compared to flat-tappet designs minimizes parasitic friction losses while distributing load more efficiently across the lifter bore, translating to measurable power gains and extended component lifespan.
