SBI Engine Parts KL8232A Valve Keepers (Valve Locks) Cylinder Head Rebuild

Manufactured by S.B. International, Inc.® — a premier worldwide supplier of cylinder head components since 1982 — these keepers are designed to meet or exceed original equipment manufacturer (OEM) specifications.

Over time, the valve train components in an engine wear in together and develop specific wear patterns. During cylinder head rebuilding, worn keepers reassembled with new valves or in mismatched order can cause stress fractures and keeper groove failures, potentially leading to catastrophic engine damage. Installing new valve keepers during every cylinder head reconditioning procedure is strongly recommended to prevent these failures.
