Racewill Trailer Shackle Kit 2-1/4" — 1-Pack straps with nylon bushings & bolts, corrosion-resistant

Racewill's 1 Pack Trailer Shackles Kit supplies a complete set of 2-1/4" shackle straps, 9/16" nylon bushings and matched bolts and nuts to restore and strengthen a tandem-axle double-eye leaf spring suspension.

When a trailer's shackles show wear they compromise ride stability and safety. This Racewill kit is built to replace the most stressed parts in a tandem axle suspension: the shackle straps, bushings and hardware. Components are made from corrosion-resistant materials and sized for common 2-1/4" leaf spring shackles, so installation returns articulation and alignment without needing to source multiple loose parts.

What parts are included and how do they fit my suspension?

The kit contains four 2-1/4" shackle straps, four 9/16" nylon bushings, and six 9/16"-18 x 3" shackle bolts with locking nuts — enough to service most tandem-axle double-eye leaf spring setups. Use the straps to replace worn links, the bushings to reduce metal-on-metal wear, and the bolts and nuts to secure the assembly.

• 4 × 2-1/4" shackle straps sized for double-eye leaf springs
• 4 × 9/16" nylon bushings for smoother pivoting
• 6 × 9/16"-18 × 3" bolts plus locking nuts for secure fastening

How does this kit improve trailer performance on the road?

Replacing worn shackles and bushings restores the designed travel and alignment of the leaf springs, which reduces sway and uneven loading. New hardware prevents loosening and maintains proper suspension geometry under load.

• Restores correct spring travel and articulation for smoother towing
• Reduces side-to-side play that can cause sway or uneven tire wear
• Locking nuts keep bolts secure under vibration and repeated cycles

How durable is the Racewill kit for outdoor and marine use?

The parts are manufactured from durable, corrosion-resistant materials suitable for exposure to road salt, water spray and outdoor storage. Nylon bushings help prevent metal abrasion, while plated bolts and treated straps increase service life compared with untreated components.

• Corrosion-resistant finishes to withstand wet conditions
• Nylon bushings reduce wear and noise at pivot points
• Designed for repeated flexing under load without premature failure

How do I install the Racewill shackle kit safely?

Installation requires supporting the trailer so the springs are unloaded, removing old shackles and bushings, and fitting the new straps, bushings and hardware in the same orientation. Torque the shackle bolts to the vehicle manufacturer's specification and recheck after the first few miles.

• Always support trailer with jack stands and chock wheels before starting
• Replace components one side at a time if alignment is a concern
• Torque bolts to factory specs and inspect after initial road use

Who this kit is for: This Racewill 1-pack trailer shackle kit is for trailer owners, fleet managers and DIY mechanics who need a complete, ready-to-install repair set for tandem-axle double-eye leaf spring suspensions.
