For racing, choose Landrum coil-over springs--not the other brands. Why? Because Landrum is serious about what they do! Manufactured in the USA from the highest grade of chrome silicon wire, their coil-over springs are closed and ground, not forged. Front coil-over springs are ground on one end, and the rear springs on both, to ensure proper contact with the jack plate and spring seats. They are cold-wound, not hot-wound. They are powdercoated, not plated. They are designed with the correct pitch and height ratio and are given standardized testing procedures. Landrum gold springs are engraved with the exact rate and serial number for each and every coil. Plus, they include the dyno data of each one, detailing the dynamic rate in graphic and numerical form. How does the serious race team cross the finish line? With the consistent, affordable, and reliable performance of Landrum coil-over springs, of course!
