Sb Chevy Cam Stop

The SB Chevy Cam Stop by MOROSO is a precision camshaft thrust button engineered for small block Chevrolet and V6 engines that demand reliable valve train control. This retaining plate assembly prevents excessive camshaft endplay—a critical failure point in high-performance builds where aggressive cam profiles and increased valve spring pressures can cause unwanted cam walk. Whether you're rebuilding a stock 305, upgrading to a performance 350, or modifying a small block V6, this cam stop protects your investment by maintaining proper cam positioning throughout the engine's operating range.

Constructed from durable PTFE (polytetrafluoroethylene) material, the SB Chevy Cam Stop minimizes friction while providing dependable thrust control without damaging the camshaft's end surface. The 0.795-inch length is engineered to fit stock and aftermarket small block Chevy timing covers without modification. The kit includes all necessary hardware and a retaining plate holder, eliminating guesswork during installation. PTFE's low-friction properties ensure smooth camshaft rotation while the rigid design resists compression from valvetrain loads—ideal for engines running solid roller cams, hydraulic roller cams, or performance street-strip combinations.

Mechanics and engine builders favor the SB Chevy Cam Stop when assembling engines intended for sustained higher RPM operation or radical valve timing events where camshaft movement creates wear patterns in the block. Installation is straightforward—position the thrust button against the camshaft's end with the retaining plate and hardware, securing it between the timing cover and block. This compact assembly (3.75 x 1.1 x 5 inches, weighing just 0.15 lbs) delivers maximum reliability with zero weight penalty. Use this cam stop on any small block Chevy or compatible V6 platform undergoing serious modification or restoration.
