ISKY 7° Chrome Moly Split Valve Locks for 11/32" Valve Stems (ISKVL-1132)

Isky 4140 Chrome Moly split Valve Locks are too tough to stamp. Our tooling marks will prove to you that they are turned on a lathe. Beware of those cheaper split locks on the market, that are merely stock cold stamped parts (some may be case hardened for a hard surface -- but they lack core strength)!

Isky Heat Treated Locks with the proper taper angle grip your valve retainers with greater locking force and will out tensile anything on the market today. They are an absolute must for today's Hi-RPM racing engines. Don't take chances with blackened or plated stock type locks masquerading as genuine heat treated Isky. The safety of your racing engine demands only the best...ISKY CHROME MOLY VALVE LOCKS.
