The LS Dual Valve Spring 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. Other features include:

• 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
