The 7-Degree Valve Lock Set Steel GM LS +.050 from PAC Racing Springs is designed for serious LS engine builders and performance mechanics who require precise valve train control in high-RPM conditions. These valve locks are essential for securing the valve spring retainer to the valve stem, helping to prevent valve float and potential engine failure during aggressive cam profiles.
Constructed from steel, this valve lock set is specifically made for GM LS platforms that require a +.050 stem diameter. The 7-degree design optimizes the lock-to-stem angle for enhanced grip and load distribution, which minimizes wear and micro-movement that can lead to valve stem damage. This durability is particularly important in applications where cylinder head temperatures may exceed 250 degrees Fahrenheit.
Engine enthusiasts working on forced induction, naturally aspirated stroker builds, or competition engines will find this valve lock set to be a crucial upgrade. The +.050 oversized stem diameter is ideal for accommodating stretched valves or custom valve specifications, ensuring proper lock geometry and reducing the risk of premature wear or failure during high-performance operation.
