Lunati Signature Series Valve Springs


No single race engine component is more critical than valve springs. Lunati’s new Signature Series Valve Springs deliver maximum performance plus reliability, for round after round winning in pro or sportsman drag racing.

Signature Series springs feature finest quality, chrome silicone, steel alloy spring wire, carefully inspected and cleaned to eliminate dirt and foreign matter. Each spring is precision wound to exact print specs, micro-shot peened, to relieve surface stress risers, and carefully heat treated, for reduced tension loss. Selected Lunati Signature Series springs are also nitride processed, for added valve lift loading and increased spring life. These premium quality valve springs are absolutely the finest available for any drag racing application.

Signature Series springs are available in a variety of designs and outside diameters to suit any engine application. Included are: Single Springs, with flat internal dampers in 1.260” OD; Dual Springs with and without dampers, from 1.300” to 1.625” OD; and Triple Springs, in 1.645” to 1.725” O.D. Signature Series valve springs are also available in “Beehive” design. These are made from a unique ovate shaped, multi-arch wire that places additional material on the inner diameter of the spring, for greater tension and spring life.

Lunati Signature Series valve springs are sold in tension-matched, hand inspected sets, ready for installation. They are also available in complete Signature Series Valve Spring Kits that include tension-matched Signature Series springs, machined steel or titanium valve spring retainers, and super strength, heat treated 7 or 10-degree valve locks.
