First developed by our engineering team in the late 1990s for NASCAR applications, Manley?s 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 ? when the system is assembled ? resides within an internal ?retention channel? located on the I.D. of the valve locks. Manley?s valve train components group, headed by Manley GM Michael Tokarchik, 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. In addition, Manley?s LocCap system retrofits to competitors? ?Lash Keeper?Note: Manley Valve lash Cap, LocCap-.3100 STEM Products specifications Attribute name Attribute value Weight 44.0 Stem Diameter 5/16 (.3100) Valve Stem Diameter 5/16 (.3100) Prop 65 (C, R or CR) CR Product Type Engine Valve Lash Cap Prop 65 - Short Label prop65warninglabel.jpg Prop 65 Yes/No Yes Country of Origin US Condition New
