AFR Valve Locks

Product images may differ from actual product appearance.

All AFR heads (except BBC) currently come with bead lock style valve locks for superior clamping over the conventional "square" locks that competitors use. Bead lock style locks spread the load of the spring force over a much greater percentage of the valve and valve lock's surface area. Bead lock valve keepers offer greater reliability and less chance of lock failure (which can lead to a dropped valve and serious engine damage).
