]]> Calvert Racing S340-44 - Split Mono Leaf Racing Springs 1998 - 2018 Chevy Silverado / GMC Sierra

Price is per pair of springs

1500 SERIES TRUCKS SPLIT MONO LEAFSPRINGS

-1" DROP RIDE HEIGHT

Half the weight of factory mono-leafpsrings, Calvert’s parabolic split mono-leaf design is built especially for street or racing ONLY. These springs are not intended for hauling or towing.

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.

Calvert Split Mono Leafsprings for 1500 Series Trucks are available in -1" Drop and Stock Height.

Please call if you are running on original springs over 20 years old; your ride height may need to be adjusted to achieve expected results.
