Every spring that is manufactured for our KNIGHT PROWLER Cams comes from PSI with wire that is made from the highest quality Chrome-Silicone alloys. The hard to find rod material for these alloys is 100% Kobe steel, long considered necessary to manufacture the cleanest, purest valve spring available in the world. KNIGHT PROWLER Valve Springs have an optional, proprietary, multi-step, surface enhancement process that has been proven to increase a spring’s endurance limit. This process can be applied to any level of the KNIGHT PROWLER series of springs. It is a very beneficial process for those looking for an increase in endurance while maintaining their existing setup.
