Valve Spring Kit for GM LS1 LS2 LS3 .675" Lift Conical Comp Cams 7230TS1-KIT

Pricing: $508.46


The .675" Lift Conical Spring Kit w/ Tool Steel Retainers for GM LS1/LS3 allows users to easily install revolutionary Conical Valve Springs on any high performance GM LS1/LS3 engine.

The springs’ conical design features a smaller diameter in the upper half to reduce active mass. This reduction in mass, along with the progressive frequency created by the conical shape, dampens coil oscillations better than any other spring design. These improvements allow for the use of more aggressive camshafts and an increase in RPM limit speed. Finally, Superfinish processing of the springs results in increased durability and spring life.
