These single groove Machined Steel Street Locks with 7 Degree lock angle & 11/32 Inch Valve Stem size are perfect replacement locks for street applications. It is critically important to make sure Valve locks match the Valve size. There should always be a small gap between the two halves of the lock when they are properly positioned on the Valve Stem. If the two halves fit together without a gap, they are too large. If the locks fit tight to the Stem & leave a gap between the middle of the lock & the Outer Diameter of the Stem, the locks are too small. Most people believe that the tang inside a Valve lock holds the retainer & Valve Spring in place while the Engine is running. This is not the case. The cross-section of material in the tang is not strong enough to withstand open Spring loads of 1000 Pounds or more. The sole purpose of the tang is to temporarily locate the lock, retainer & Spring relative to the Valve until the taper of the retainer can nest around the outside surface of the lock. This creates a “Collet” effect that binds the two together. The more Spring force exerted on the retainer (as the Valve opens), the more force applied by the “Collet” effect to keep the retainer & lock in place.
