Ferrea Super 7 Degree 0.275 (7mm) Std. Radial Groove Steel Valve Locks - Set of 8

These Ferrea Super valve locks are made from strong steel and feature a 7-degree angle with standard radial grooves. This design helps ensure your valve springs stay properly seated, even under demanding conditions. They are designed to work with 0.275-inch (7mm) valve stems, making them a solid choice for many performance engine builds where valve control is critical.

The radial groove design offers a good grip on the valve stem, preventing slippage and maintaining consistent spring pressure. Being made of steel means they offer good durability for their intended use. This set includes eight locks, enough for a typical four-cylinder engine's intake and exhaust valves.
