11/32 Valve Locks - 7 Degree Steel

PAC Racing Springs 11/32 Valve Locks with 7-degree angles deliver precision valve train control for high-performance engine builds. These steel valve locks are engineered to secure valve stems during aggressive engine operation, preventing valve float and maintaining consistent valve timing under extreme RPM conditions. As a complete set of 16 locks finished in black oxide, this PAC-L8146-16 kit provides the redundancy and reliability required by engine builders and performance enthusiasts working with 11/32-inch valve stem diameters.

The 7-degree angle geometry is critical for camshaft compatibility and spring pressure optimization. This specific angle works in concert with modern valve spring assemblies to minimize valve stem wear and maximize lock engagement during high-lift, high-duration cam profiles. Steel construction with black oxide coating provides corrosion resistance and durability across multiple engine seasons. Standard height design ensures compatibility with most aftermarket valve spring kits without requiring custom machining or adapter components.

Engine builders, race mechanics, and performance enthusiasts select PAC valve locks for naturally aspirated and forced-induction applications where valve train reliability cannot be compromised. These locks are essential for turbocharged, supercharged, and high-horsepower naturally aspirated engines operating at elevated boost levels or extended RPM ranges. The complete set of 16 accounts for eight-valve configurations with spare locks included for replacement or future builds.

PAC Racing Springs maintains strict manufacturing standards for valve train components, with each lock manufactured to precise dimensional specifications. Proper valve lock installation requires correct spring seat pressure and compatible valve spring hardware—factors that must be verified during engine assembly to ensure optimal performance and longevity.
