COMP Cams Valve Locks Eb 5/16in 7Deg - Set of 100

The 7-degree taper on these COMP Cams valve locks is a key design choice, ensuring they work with standard 7-degree retainers to create a strong collet effect. This effect is what truly holds the retainer and valve spring in place as the engine runs, not just the tang. The tang's main job is just to position everything until that collet grip takes over. These locks are made from machined steel, offering a solid option for street applications where spring loads are typically lighter.

It's important that your valve locks match your valve stem size precisely. These are designed for 5/16 inch valves and feature a single groove. When installed correctly, there should be a small gap between the two halves of the lock. If they fit together with no gap, they're too large, and if they leave a gap between the lock's center and the valve stem's outer diameter, they're too small. This set includes 100 pieces, making it suitable for a full engine rebuild.
