The Supertech Performance KPR-5.5-7A-LG-32 valve locks are precision-engineered, CNC-machined valve keepers designed for high-performance engine builds. This complete set includes 32 valve locks, providing enough components for a 16-valve engine (requires 2 locks per valve).

Key Specifications:

• 5.5mm stem diameter with 7-degree keeper angle
• 0.045 inches longer than standard valve locks for increased spring height
• Single groove design for secure valve spring retention
• CNC-machined from hardened steel for superior durability
• Compatible with most aftermarket and stock valve spring retainers

Performance Benefits:

• Ensures proper valve spring pressure and alignment during high-RPM operation
• Enhanced durability and resistance to wear in demanding applications
• Precision fit reduces risk of valve spring failure
• Ideal for high-revving engines and performance valve train upgrades

These valve locks are commonly used in Honda B-series, K-series, D-series, H-series, and F-series engines, making them a popular choice for Honda and Acura performance builds. The longer design accommodates taller valve spring setups often used with aftermarket camshafts and performance valve springs.
