COMP Cams Titanium Super 7 Valve Locks

When you're rebuilding the top end of your engine, getting the right valve locks is crucial for proper valve train function. This set from COMP Cams includes 16 Titanium Super 7 Valve Locks, specifically designed for 8-degree retainers and 11/32-inch valve stems. These locks are made from titanium, which makes them notably lightweight compared to steel, helping to reduce valve train mass. This can lead to improved performance and durability under high-RPM conditions.

It's important to ensure your valve locks match your valve size precisely. COMP Cams designed these locks with an 8-degree angle to work with compatible retainers. When installed correctly, there should be a small gap between the two halves of the lock when they're seated on the valve stem. If they fit together without a gap, they're too large, and if they leave a gap between the middle of the lock and the stem's outer diameter, they're too small. The tang on the valve lock's primary job is to temporarily position the lock, retainer, and spring until the retainer's taper creates a secure 'collet' effect, binding them together. The more spring force applied, the stronger this binding action becomes.
