This spring is engineered for street/strip hydraulic roller and some solid roller LS1 camshafts and features a 1.320″ outside diameter and a .660″ maximum lift. It has a seat load of 141 @ 1.810″, an open load of 405 @ 1.150″ and a spring rate of 400 lbs./in. This lightweight, high lift dual spring is also polish finished to actually help with the reduction of stress in the valve train. In addition, the small diameter of these springs increases harmonic frequency, enabling much better valve train control at higher rpm. With a host of other specialized features, these springs were created for unmatched performance and durability in performance street/strip LS1 engines.
Although engineered with GM LS1 engines in mind, these springs can also be used with many other popular engine applications. For more information about the COMP Cams #26925 Street/Strip Dual Valve Spring or any other COMP Cams® product, call toll free at 1-800- 999-0853, or visit www.compcams.com.
