Comp Cams Super Lock Steel Retainers - Set of 16 Shown here is our Comp Cams 10 degree "Super Lock" Steel Retainers. These are a huge, extremely beefy valve retainer which is designed to fit our Comp "Super Locks," which can be found on our Valve Locks page. This 10 degree lock & retainer system has a wider angle of interference than a standard 7 degree lock. These are fully machined from 4140 Chrome Moly and finished in black oxide. Comp recommends these for any cams over .460" lift. We highly recommend upgrading to these for extra insurance. These are supplied in a set of 16, enough to do one complete engine. Since they're Comp, you can be assured of two things: They're 100% made in the USA, and the quality is second to none.
