COMP Cams GM LS CONICAL VALVE SPRING KIT W/ TOOL STEEL RETAINERS

Complete Kit Allows Installation of Revolutionary Conical Valve Springs on Nearly Any GM LS
LS Conical Valve Spring Kits allow enthusiasts and uilders to better harness the power of popular LS race and street engine applications. Each kit features Conical Valve Springs, valve locks, valve seals, spring seats and either chromemoly steel or high-strength tool steel retainers. The springs’ conical design means that they feature a smaller diameter in the upper half to reduce active mass. These springs are thus effectively smaller and lighter than otherwise possible for similar loads and lifts. The result is a lowering of parasitic horsepower losses, more power, an increased RPM limit, improved stability and the ability to run more aggressive camshafts. The conical design also features progressive frequency which dampens coil oscillations better than any other design naturally. Finally, Superfinish surface processing increases lift capability and spring life. COMP Cams® LS Conical Valve Spring Kits feature all the components needed to install these revolutionary springs with no machine work required.
