R&D has developed an economical solution for upgrading the upper valve train by offering a one stop shopping parts upgrade kit that will work great in the 8500-9000 RPM range in an economical price range. The kit includes our “Super Single” chrome silicone valve spring, precision machined premium grade titanium top spring retainers, and custom designed bottom spring/locator cup. The R&D “Super Single” Valve Spring Kit is a recreational and offshore upgrade favorite which offers great valve control and adds improved strength and reliability by changing out the stock steel retainers known to crack for super strong, lightweight titanium. As an industry rule, as RPM'S are increased, the spring pressure at full lift should be increased as well to reduce or eliminate valve float at high rpm frequencies. With the stock springs “short lift travel” shimming is NOT an option. Valve Springs and Parts MUST be upgraded. Also to consider is valve spring travel at full cam lift, and to have enough spring clearance freedom to run high performance camshafts or add additional spring tension pressures without coil bind issues. R&D will soon release the spec of these springs and retainers. The Retainers are IJSBA Legal for Pro Stock class whilst the Springs are IJSBA legal for Limited class. Call R&D for price and availability.
