660 Lift Dual Valve Spring Kit for GM LS-based applications. The kits come complete with dual valve springs, retainers, spring locators, locks and valve seals that are ready for drop-in installation on many popular LS applications. Using a Signature Series Valve Spring, Lunati engineers have developed new wear-favorable, lightweight alloy steel retainers and locators. These designs prevent chafing in the spring pockets of aluminum heads, making the combination unbeatable for both serious performance street and drag racing. Locks equipped with inner bead locks; 7° interference angle between locks and retainers causes the locks to clamp valve stems more tightly.Valve seals are made from Viton synthetic rubber and are steel jacketed to guarantee seals remain tight around guides and are protected from springs. Viton material is ideal for resisting heat and aggressive racing oil additives that cause swelling and distortion. Outside Diameter (Outer): 1.306. Spring Rate (lbs/inch): 379 lbs/in. 73925K1 (Lunati Gold Dual Valve Spring Kit).
