5/8" x 2" x 7/16" Rod, Shackle for Rear Torsion Arm

Shackles are used to position the torsion arm at the correct angle for the correct progressive spring rate. Torsion arm angle is a function of shackle length in combination with bearing carrier plate hole location. Approximately 1" or 1-1/4" difference in length between the left rear shackle and the right rear shackle is recommended for proper torsion arm angle with the left rear being longer.

Our black anodized shackle rods are available in 2", 2.5", 3", 3.5" and 4" lengths. If purchasing just the rod, pick up the corresponding rod ends and jam nuts: 71-CML7 (1), 71-CMR7 (1), 70-325 (1) and 70-326 (1). Complete shackle assemblies which include the rod ends and jam nuts are also available.

On the X4 and X6 style bearing carriers, the right rear is typically just a female and male rod end threaded together making a 3-1/4" center to center shackle and the left rear is a 2" shackle rod making a 4" center to center shackle with the rod ends screwed in.
