10 Degree Valve Locks - Bead-Loc Style

The Manley 10 Degree Valve Locks in bead-loc style are precision-engineered components designed for high-performance engine builders and competitive racing applications. This set of eight steel valve locks is specifically crafted to secure valve springs with a 10-degree taper angle, preventing spring slippage and maintaining critical valve train geometry under extreme conditions.

These valve locks feature a bead-loc design that enhances the retention of keepers, reducing the risk of keeper rotation and spring surge failure, which is crucial at high RPMs. The black oxide finish provides corrosion resistance, making them suitable for valve train components exposed to combustion heat and oil circulation.

Engine builders preparing for competition or sustained high-performance operation will find these valve locks essential. With compatibility for a broad range of small-block and big-block engine platforms, they ensure proper keeper-to-valve stem engagement and prevent accelerated wear on components.
