CALMINI Heavy Duty lift shackles for all 4WD pickups. The perfect addition to achieve an extra 1" of lift in the rear of the truck to match a torsion bar adjustment or to compensate for worn-out factory springs. The complete kit includes precision laser crafted, powdercoated shackle plates, bolts, flat washers, and Nylock nuts. Installation is entirely bolt-on and can be completed at home with simple hand tools. Kit sold as a pair.
