5/8" x 2.5" x 3/8-24 Rod, Shackle for Torsion Arm, Junior Sprint

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 for Junior Sprints are available in 2", 2.5", 3", and 3-1/2" lengths. If purchasing just the rod, pick up the corresponding rod ends and jam nuts: 71-CML6BLK (1), 71-CMR6BLK (1), 70-320 (1) and 70-321 (1).
