Manley Street Master Steel Valve Spring Retainers

Manley Street Master Steel Valve Spring Retainers are CNC-machined engine valve spring retainers (also called spring caps) built for street, street/strip and performance engine builds. Each retainer is made from through-hardened 4140 chromoly steel. It holds the valve spring securely and gives consistent spring seating in the valvetrain.

Key Features:

• Through-hardened 4140 chromoly steel construction for strength and durability
• CNC-machined on Manley's in-house turning centers to exacting tolerances for consistent quality
• Designed for the demands of street and strip performance use
• Available in a range of spring diameters, lock angles and heights to match many popular valve spring and cylinder head combinations
• Made by Manley, an engine components brand trusted by professional engine builders since 1966

A solid upgrade for builders who want durable steel retainers from an established valvetrain manufacturer. Choose the configuration that matches your valve springs, valve stems and locks. Locks are generally sold separately.
