SBC Roller Cam Button .795in Length

The SBC Roller Cam Button .795in Length from COMP CAMS is a precision camshaft thrust button engineered for small block Chevrolet engines. This essential component controls camshaft end play and prevents unwanted axial movement, protecting your valve train from damage during high-RPM operation. Whether you're building a street engine, performance upgrade, or full race application, a quality cam button is critical to engine longevity and reliability.

Constructed from hardened steel and finished in black oxide, the SBC Roller Cam Button measures 0.795 inches in length and is specifically designed for roller camshaft configurations. The black oxide coating provides superior corrosion resistance while maintaining a professional engine bay appearance. Its compact 0.1 lb weight and precision machining ensure proper fit and function without excess material, allowing optimal flow through the block while maintaining structural integrity under extreme operating conditions.

This cam button is ideal for small block Chevy engine builders and enthusiasts upgrading to roller camshaft technology. Installation requires proper clearance verification between the camshaft sprocket and block—the 0.795-inch length is engineered to maintain precise end play specs, typically 0.003 to 0.006 inches. Compatibility with roller cam configurations makes this component essential when converting from flat-tappet to roller systems, and it pairs seamlessly with stock or performance valve train components across generations of small block Chevrolet platforms.
