Valve Locks - 10 Degree +.050

CROWER Valve Locks in 10 Degree angle with +.050 in additional height are precision-engineered components designed for high-performance engine builders and cylinder head specialists. These jumbo-sized valve locks are manufactured from chromoly steel and deliver the secure valve retention required in racing and modified engine applications where spring pressures and valve train geometry demand maximum reliability.

The 10-degree angle geometry is critical for valve stems measuring 11/32 inch in diameter, ensuring proper seating and load distribution across the valve keeper groove. The +.050 inch additional height specification allows builders to adjust installed height without shimming under the retainer, a significant advantage when fine-tuning valve spring pressure to match specific camshaft profiles and lift characteristics. The natural chromoly finish provides corrosion resistance without coating buildup that could affect precision clearances. This set includes 16 locks—enough for a complete eight-cylinder engine with spares for testing and installation verification.

Engine builders, race teams, and performance shops rely on CROWER valve locks for street and competition builds where valve train stability is non-negotiable. Whether assembling a naturally aspirated engine or working with forced-induction applications, correct lock geometry directly impacts valve seat durability and prevents catastrophic valve drop under high RPM operation. The 10-degree angle and oversized profile are specifically suited to modern cylinder head designs that require precision component matching.

CROWER maintains a well-established reputation in the engine component market, with products widely trusted across drag racing, road course, and street performance communities. These valve locks are part of a complete CROWER valve train system ecosystem, allowing builders to source matched components with confidence in dimensional accuracy and material quality.
