Super Swivel Shackles

POSIES Super Swivel Shackles are the newest addition to our Hot Rod Parts and Super Slide Spring line. These shackles work perfectly with our ElliptaSlide quarter elliptic spring kits or other custom suspension applications. The shackle is designed around a swivel joint that allows up to 30 degrees of rotation between the spring and axle, virtually eliminating any binding of the spring. The joint is enclosed in UHMW races with a threaded locking ring used to adjust the amount of compression on the joint. Adjusting tool sold separately. Super Swivel Shackles can be retrofitted to existing suspensions with shackle alignment issues. Super Swivel Shackle kits are available for front I-beam/tube axles and rear axle housings.
