Pro Valve Yamaha Titanium Retainer Dual Spring & Locator Set

Pro Valve Racing Yamaha Titanium Retainer Set includes 16 Titanium retainers that are manufactured with high quality Ti17-64 military grade certified Titanium alloy and are CNC machined for a tight fit to prevent premature wear and also assure that every retainer is within tolerance. Pro Valve Racing Dual Valve Spring Set includes 16 Dual Valve Springs that are computer designed to ensure that wire stress levels do not surpass the limits of stress defined in the diagrams of fatigue. Pro Valve also utilizes FEA (Finite Element Analysis) to control. This combined with our proprietary CSV alloy enables Pro Valve Racing springs to be more durable in extreme conditions. Pro Valve Racing Spring Locator Set includes 16 spring locators that are manufactured from hardened 4140 steel alloy that not only protects the aluminum cylinder head casting but also precisely locates and holds the valve spring in place to prevent any possibilities of spring assembly rotation at extreme RPM.
