Super 7 Valve Locks - +.050in

The Super 7 Valve Locks - +.050in from MANLEY are essential components for serious engine builders and high-performance mechanics focused on achieving peak cylinder head reliability. These valve locks secure the valve spring retainer to the valve stem, preventing rotational slippage that can lead to catastrophic failures in high-stress environments.

Designed to accommodate +.050-inch oversize valve stems, these locks are ideal for engines with worn or modified stem diameters. The precision-machined geometry ensures a secure fit and minimizes lateral play, which is critical for managing aggressive valve spring pressures in racing applications.

These valve locks are particularly beneficial for engines utilizing custom billet valves or during head porting processes. With their superior material quality and consistency, they reduce the risk of galling and deformation, making them a reliable choice for high-performance builds.
