The COMP Cams 3/8in 10 Degree Super Locks with +.050in Installed Height (SKU COM616-16) are precision valve locks engineered for serious engine builders and high-performance applications. This 16-piece set delivers the controlled, reliable valve stem retention that modern cam profiles and aggressive valve spring pressures demand. Super Locks represent a significant advancement over traditional single-piece valve locks, offering superior concentricity, reduced radial clearance variation, and consistent preload across the entire set.
Each lock is manufactured from hardened steel with black oxide finish for corrosion resistance and durability in high-temperature engine environments. The 3/8-inch valve stem size accommodates popular small-block and mid-block configurations, while the 10-degree angle geometry matches the corresponding 10-degree locks commonly paired with modern valve spring seats. The +.050-inch installed height specification allows builders to fine-tune rocker arm geometry and pushrod preload without sacrificing valve control. All 16 locks in this set are precision-matched and ready to install.
This set is designed for engine builders, performance machine shops, and serious enthusiasts rebuilding or upgrading small-block engines with performance camshafts. Whether assembling a naturally aspirated high-RPM engine, forced-induction build, or street performance application, proper valve lock selection directly impacts long-term reliability and consistent valve train geometry. COMP Cams Super Locks are a proven choice for builders who demand precision and consistency across all 16 valve positions.
Valve locks are critical valve train components often overlooked by builders prioritizing other upgrades. However, inadequate lock geometry can lead to gradual valve stem wear, inconsistent preload, and premature valve spring failure under load. COMP Cams' Super Lock design minimizes these risks through tighter tolerances and repeatable split-lock geometry that maintains consistent clamping force.
