Melling Stock Replacement Valve Locks (Valve Keepers)

Melling Stock Replacement Valve Locks — also commonly referred to as valve keepers — are precision-engineered engine components designed for use during engine rebuilds and valve service. Valve locks must always be replaced with new units whenever servicing engine valves, whether installing reclaimed or brand-new valves. Reusing worn valve keepers risks valvetrain failure and engine damage.
