SBI Engine Parts KL7708 Valve Keeper Set Cylinder Head Rebuild

The SBI Engine Parts KL7708 is an aftermarket valve keeper (valve lock) set designed for cylinder head reconditioning and engine rebuilding applications. Manufactured by S.B. International, Inc.® — a premier worldwide supplier of cylinder head components — these valve keepers are engineered to meet or exceed OEM specifications for a reliable, long-lasting repair.

Valve keepers play a critical role in securing the valve spring retainer to the valve stem. Over time, mating valve train components develop wear patterns unique to their paired parts. Reusing worn keepers during a head rebuild — especially alongside new valves — can create mismatched wear interfaces that lead to stress fractures and potentially catastrophic valve train failure. Replacing the valve keepers during every cylinder head reconditioning procedure is strongly recommended.

Key Features:

• Manufactured by SBI® (S.B. International, Inc.), a trusted name in cylinder head components since 1982
• Designed and manufactured using high-quality hardenable steels or carbon steels depending on application requirements
• Hardness range of 40–50 HRc (File Hard) for standard applications; select heavy-duty applications may utilize a carbonitriding (case hardening) process for a minimum of 55 HRc
• Meets or exceeds OEM specified requirements for proper fitment and service life
• Available in multiple styles including Square Groove, Round Groove (1, 2, 3, and 4 Bead), No Bead, and Pin Type
• Each keeper is precision-manufactured — either via stamping or machining depending on the specification — to ensure consistency and quality
• Designed to maximize service life and prevent valve keeper groove failures

The SBI KL7708 valve keeper set is an essential component for professional engine rebuilders and technicians performing cylinder head reconditioning. Always install new valve keepers during any head rebuild to help prevent premature failure and ensure proper valve train function.
