Brian Crower Single Valve Spring Steel Retainer Kit

The Brian Crower Single Valve Spring and Steel Retainer Kit line gives your engine's valvetrain a performance upgrade. Each kit pairs high-rpm valve springs with CNC-machined steel retainers. Together they help control the valves at higher engine speeds, with more cam lift, and under more demanding conditions than stock parts. Use them for performance street builds, track cars, and racing engines.

Key Features:

• High-rpm valve springs: Wound by PAC Racing from super clean chrome silicon alloy. Proprietary processing gives consistent spring pressures.
• Steel retainers: Matched to the spring in each kit. Steel is a durable choice for high-mileage and daily-driven applications.
• Single spring design: One spring per valve, with seat and open pressures engineered for the specific engine application.
• Matched components: The spring and retainer are specified together for each application, so the kit works as a system.
• Direct-fit upgrade: Designed to replace the factory valve springs and retainers.

Brian Crower is known for high-performance engine internals, including camshafts, connecting rods, crankshafts, and valvetrain components. These valve spring kits let you keep valve control as you raise rpm and power. Choose the specific kit for your engine from the available options.
