Product Details
Signature Series Ovate Beehive Valve Spring (74814-1) by Lunati®. In any spring, the inner diameter experiences significantly more stress than the outside. The ovate multi-arch wire design of these revolutionary valve springs places more material on the inner diameter of the spring, which more evenly distributes stress throughout the wire cross-section and increases the overall life of the spring. Other features of the Signature Series Ovate Beehive Valve Springs include reduced mass in the retainer end of the spring, which increases RPM potential, and reduced coil surging for more valve control and longevity. Lastly, a thinner cross-section wire gives more coil bind clearance to allow for camshafts with higher lift or higher ratio rocker arms. The Signature Series Ovate Beehive Valve Springs are the ultimate in cutting-edge valvetrain performance. Get some serious horsepower with an outlaw attitude by upgrading to this performance engine part from Lunati. Built with a rich heritage of precision engineering and innovation, this high-value Lunati product is designed to provide winning performance, rock-solid durability and the best fit possible. So, if you want to put tons of power under your vehicle’s hood and make it go faster, go with this high-value performance upgrade.
