Description

These -1" drop height split mono leaf springs are designed to control and reduce excessive body separation in the rear suspension and plant the rear tires without unloading. They feature a parabolic rear half design to distribute main spring pressure, reducing spring breakage. They are assembled to order with grade 8 hardware, heavy-duty alignment clamps, aluminum bushings in the front spring eyes, and polyurethane bushings in the rear spring eyes. They have been proven to withstand over 2,500 HP at ¼ mile ETs in the 6s.
