PAC Racing Springs is the manufacturer of high quality valve springs and retainers for all high performance engines. These are the same springs we include with our custom Bullet Racing Cams for your high performance, high revving Mod Motor.

PAC 1500 Series Springs offers an industry leading nitriding process that allows for the material to withstand the abusive wear and fatigue of the typical endurance engine environment. These springs come fully prepared for performance applications and come with additional polishing and surface enhancements. From 24 hours of LeMans to the rigors of NASCAR, the 1500 Series spring has the history to withstand the most demanding environments.

These springs are unique in that you use the same spring for both intake and exhaust, but the retainers are used to get the proper install height (exhaust retainers are +0.060 thicker).
