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.

Parabolic rear half design distributes the main spring pressure point through the length of the half, reducing spring breakage.

All of Calvert Racing’s 2.5″ wide 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.

Made in USA.

 

These springs are designed for DRAG RACING and have a higher spring rate / stiffer ride than stock springs. Spring halves are painted black before assembly, but some raw steel may show due to deburring/grinding sharp edges.

 

*If you have the original perches installed, you will need our Space Adapter Plates: SP-1 (for multi springs) or SP-3 (for mono springs).
