Chevy Thrust Button .690in Short

The Manley Chevy Thrust Button .690in Short is a precision camshaft component designed for serious engine builders and performance enthusiasts working on small-block and big-block Chevrolet platforms. This thrust button is crucial for controlling axial movement of the camshaft within the block, helping to prevent wear on critical engine internals and maintaining proper valve timing under high-RPM conditions.

Engineers and mechanics modifying Chevy engines for street performance, drag racing, or engine rebuilds will find this thrust button essential for long-term reliability. Manley's .690-inch short design is manufactured to exact OEM tolerances with durable materials that resist thrust loads during aggressive cam profiles. This precision fit prevents camshaft walk, a common failure point in modified engines running solid lifters or roller cams.

Engine builders, machine shops, and DIY mechanics installing performance camshafts on Chevy small-block 350, 383, 400, or big-block engines will benefit most from this component during complete bottom-end assembly. Proper installation requires verification of camshaft end-play using a dial indicator to ensure optimal performance.
