Includes all valve springs and retainers for your engine.

The perfect match for your new cams are Brian Crower Valve Spring and Retainer Kits. Each valve spring is designed to control valve movement at extreme lifts and high RPMs. Each valve spring is wound from high grade chrome silicon alloy for consistent spring pressure specifications. Dual Spring applications help prevent harmonics and valve float, and are especially recommended for high RPM motors. Each kit also comes with steel or titanium spring retainer caps too. The titanium retainers are each machined from premium 6AL4V bar stock to exacting tolerances. The titanium retainers are designed for race use and offer the lightest weight available to keep valve inertia to a minimum. They do wear faster so you will have to replace them more often than steel. Brian Crower also offers steel valve spring retainers, so if you have a high performance daily driver you can still run high lift cams without having to worry about the retainers wearing out from daily use. They do weigh a small amount more, but will last the life of the motor.

Additional Fitment Notes: For best performance we also recommend using Brian Crower Billet Valve Locks, if available. This will help ensure that the spring, retainer, and valve will stay properly connected under even the most extreme race conditions.
