Calvert Racing Split Mono-Leaf Springs
Engineered for drag racing, Calvert Racing split mono-leaf springs have a higher spring rate and a stiffer ride than stock springs. Tested on the fastest stock suspension cars in the world, they are designed to control and reduce excessive body separation in rear suspension and plant the rear tires without unloading. The parabolic rear-half design distributes the main spring pressure point through the length of the half, reducing spring breakage. Calvert Racing split mono-leaf springs are assembled to order with Grade 8 hardware, heavy-duty alignment clamps, front aluminum bushings, and rear polyurethane bushings. They are stress-relieved and arch verified, available in several ride height options, and have been proven to withstand over 2,500 hp at 1/4 mile ETs in the 6s. Choose the springs designed for your vehicle.
