Bead Lock Keepers

All AFR heads (except BBC) currently come with bead lock style valve locks for superior clamping over the conventional “square” locks our 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). We are currently implementing the change on our BBC product but it will take some time before the change is complete.
