Description
Valve locks are critical to high-RPM engine reliability—they’re the only thing keeping your valve train intact under extreme load and combustion pressure. Manley’s 7-degree locks deliver precision engineering with a reduced-height design that optimizes geometry in tight engine bays while maintaining the clamping force your LS1/LT1 demands. If you’re building a serious engine or pushing existing limits, these locks are non-negotiable.
