Description
Valve locks are critical components that secure your valve keepers under extreme cylinder pressures and high-RPM operation. Without proper locking geometry, you risk valve float, dropped valves, and catastrophic engine failure. Manley’s 10-degree valve locks deliver the precision angle and robust steel construction necessary for reliable valve train performance across a wide range of applications.
This 32-piece set ensures you have adequate coverage for complete engine builds or rebuilds, whether you’re assembling a naturally aspirated platform or a forced-induction setup. The 10-degree angle geometry is engineered to maintain optimal keeper engagement under sustained load, while the standard height simplifies installation without requiring custom fabrication or modification.
