Valve Locks - 10 Degree Bead Lock GM LS1/LS6

The Valve Locks - 10 Degree Bead Lock GM LS1/LS6 from COMP CAMS is an essential component for high-performance GM LS-series engine builds and modifications. Valve locks secure the valve spring retainer to the valve stem, preventing unwanted separation during extreme engine conditions. For serious LS engine builders, drag racers, and street performance enthusiasts, these Super Locks deliver the reliability needed when running aggressive cam profiles, high valve spring pressures, or boost applications that demand maximum valvetrain stability.

Engineered in steel with black oxide finish, these valve locks feature a 10-degree bead lock design that provides superior engagement with the valve stem groove for LS1 and LS6 platforms. The bead lock geometry distributes load across a wider contact surface, reducing the risk of lock migration or loss during sustained high RPM operation. Designed for 8mm valve stems, this complete set of 16 locks ensures you have replacements for all intake and exhaust valve positions, making installation straightforward during valve job rebuilds or cam upgrades. The precision engineering means consistent performance across all eight cylinders with no variation in spring retention.

LS engine enthusiasts building for track duty, forced induction, or naturally aspirated high-RPM applications will find these locks indispensable for maintaining valvetrain integrity. Whether you're refreshing a tired LS with a new camshaft or assembling a complete performance head, proper valve lock selection is non-negotiable. Installation pairs seamlessly with performance valve springs, titanium retainers, and custom cam packages. These locks meet the demands of modern LS tuning, from street cars pushing 400+ hp to dedicated race engines seeing 8,000+ RPM on the dyno.
