Valve Locks, Machined, Hardened Steel, 7 Degree,1-Groove,11/32 in. Valve Stem, Set of 16
Valve locks for today's high engine speeds from Crane.
Crane machined steel valve locks are available in the following three styles: 7 degree locks, 7 degree Super Duty valve stem locks, and 10 degree locks. All three styles are machined from the highest quality alloy steel billet material, and then heat-treated for maximum strength and durability. The 7 degree locks were engineered specifically for today's high engine speeds and high-tension valve springs. They feature an oxide finish for corrosion protection. The 7 degree Super Duty valve stem locks feature added outside diameter material for increased strength, durability, and fatigue resistance. They are recommended for any high-rpm, high valve spring tension or heavy valve application prone to lock distortion and retainer pull-through. The 7 degree taper actually provides more clamping force than wider 10 degree taper locks. The 10 degree locks feature a 10 degree taper, which many engine builders prefer. They are suitable for any racing application where the 10 degree design is specified.
