Crane Cams Steel 7° Valve Stem Locks
Stamped Steel Locks 7° - Single Groove Design These valve stem locks are manufactured from premium quality alloy steel, precision diestamped and then heat treated for maximum strength. These locks are considerably stronger than stock, and are excellent for all street-performance and moderate racing engine applications.
Machined Steel Locks 7° - Single Groove Design The ultimate in strength and wear resistance. These locks are machined from highest quality alloy steel billet material using the finest automatic screw machines and then carefully heat treated. Engineered specifically for today's high engine speeds and high-tension valve springs. These machined steel locks are the only locks to be used with our "Posi Lock" valve spring retainers. Oxide finished for corrosion protection, and color coded for assembly height identification.
Machined Steel Locks 7° - Single Bead Design These machined steel locks are precision machined and heat treated in our own facility for the latest generation of engine technology. Although primarily designed for the Chevrolet LS1/LS2/LS6 families, they are also applicable to most valve stems that require a bead-style valve lock.
Multi-Fit Valve Stem Locks 7° - Single Groove Design These steel billet heat treated Multi-Fit locks feature an increased outside diameter for additional strength, durability and fatigue resistance. These Multi-Fit locks are highly recommended for any high RPM, high valve spring tension, or heavy valve application prone to lock distortion and retainer pull-through. The 7° taper actually provides more clamping force than wider 10° taper locks and are the preferred choice of professional engine builders and racers. (Use only with Crane Multi-Fit retainers).
Multi-Fit Valve Stem Locks 7° - Single Bead Design The steel billet heat treated Single Bead Multi-Fit locks provide all of the strength and durability advantages of the single square groove design, and are compatible with most of the aftermarket bead lock valves currently available. Also available in +.050" and -.050" assembly height versions for 5/16" and 11/32" valve stems, these are designed specifically for use with only our Multi-Fit retainers.
