Manley Valve Spring Retainers Chromoly Steel

Manley Street Master chromoly steel valve spring retainers (also called spring caps or valve spring caps) are made for street performance, street/strip and racing engine builds. Each retainer is through-hardened 4140 chromoly steel. It holds the valve spring in place and locates the valve lock at the top of the valve stem.

Key Features:

• Through-hardened 4140 chromoly steel construction for strength and durability under high spring loads
• Made to tight tolerances for consistent quality and performance
• Offered in a range of lock angles and spring configurations to suit different valvetrain setups
• A strong, dependable upgrade over stock retainers in performance valvetrain builds
