Tested on the fastest stock suspension cars in the world, Calvert’s Split Mono Leafsprings are designed to control and reduce excessive body separation in rear suspension and plants the rear tires without unloading.

All of Calvert Racing’s Split Mono Leafsprings are assembled to order with grade 8 hardware and heavy-duty alignment clamps. Aluminum bushings are pressed into the front spring eyes and polyurethane bushings in the rear spring eyes, these springs have been proven to withstand over 2,500 HP at ¼ mile ETs in the 6s.

NOTE: Calvert Racing Springs are designed for DRAG RACING and have a higher spring rate / stiffer ride than stock springs. Spring halves are dipped in black paint before assembly, but some raw steel may show due to deburring/grinding sharp edges.

Calvert Split Mono Leafsprings are designed to work with CalTracs to maintain arch. While street driving does not put undue stress on the springs, racing with Calvert springs without a traction device installed may result in bent or de-arched springs.
