Manley first developed the LocCap system in the late 1990s for NASCAR applications, The LocCap system is designed to retain the wear cap on the tip of the valve by employing an external bead on the wear cap that resides within an internal “retention channel” located on the I.D. of the valve locks. Manley’s valve train components group, refined the original designs combining a state-of the-art steel alloy and ultra precise manufacturing techniques to achieve the goal of delivering a no compromises valve lock/wear cap assembly for the supercharged classes. Manley’s LocCap systems are available in true 7° as well as 10° and Super 7° assemblies for 3/8", 11/32" and 5/16" stem valves in both Manley Bead Loc and conventional square groove configurations.
