Lamb Coil-Over Springs are the finest available in racing period. Designed to outperform and outlast all other brands, Lamb springs are made of chrome vanadium, the same material used in high-performance valve springs. Each Lamb spring is heat-set, shot-peened and magnafluxed, and accordingly cannot be overstressed in competition usage.
During the manufacturing process, each Lamb spring is tested on a machine that is calibrated and accurate to the Bureau of Standards. The theoretical spring rate and actual proof rate is then engraved (not stenciled) on the spring end. Springs are matched according to the proof rate.
