Racewill Trailer Shackle Kit 2-1/4" 1-Pack — Tandem-Axle shackle straps with bolts & nylon bushings for restored suspension articu

If your trailer uses a tandem-axle double-eye leaf spring setup, the shackles are critical wear points that control spring travel and articulation. The Racewill 1 Pack Trailer Shackles Kit supplies the common replacement components — heavy-duty 2-1/4" shackle straps, matching bolts, locking nuts, and nylon bushings — so you can service both sides quickly and get back on the road. The hardware is made for outdoor use with materials chosen to resist corrosion and normal road stresses.

What exactly is included in this Racewill shackle kit?

The kit contains everything needed to replace shackles on a single tandem-axle leaf spring connection. Parts are sized for typical 2-1/4" shackle straps and 9/16" bolt assemblies.

• 4 pieces 2-1/4" shackle straps (steel)
• 4 pieces 9/16" nylon bushings to reduce wear and noise
• 6 pieces 9/16" - 18 x 3" long shackle bolts
• 6 locking nuts compatible with the bolts for secure fastening

How does this kit help maintain trailer suspension performance?

Shackles are the moving link between the leaf spring and the trailer frame; worn or seized shackles change spring geometry, cause binding, and accelerate wear. Replacing them restores free articulation and reduces stress on adjacent suspension parts.

• Fresh bushings reduce metal-on-metal contact and noise.
• New bolts and locking nuts ensure correct clamp and prevent loosening.
• Properly sized straps restore original ride geometry for safer towing.

Are these shackles compatible with my trailer and how do I check fit?

The Racewill components are designed for tandem-axle double-eye spring suspensions that use 2-1/4" shackle straps and 9/16" bolts. Measure existing strap width and bolt diameter to confirm fit before installing.

• Measure the inside strap width — should be 2-1/4" for direct replacement.
• Confirm bolt diameter at 9/16" and length at approximately 3" to clear thick spring eyes.
• Check frame clearance and orientation for tandem-axle applications.

What materials and durability features does the kit offer?

Racewill supplies parts made from durable metal and corrosion-resistant finishes suitable for exterior vehicle use. The nylon bushings add resilient wear resistance where most movement occurs.

• Shackle straps made of premium steel for strength under load.
• Nylon bushings reduce friction and extend the life of both spring eyes and shackles.
• Bolts and locking nuts sized for secure, vibration-resistant fastening.

Who is this for: This Racewill shackle kit is intended for trailer owners, fleet managers, and DIY mechanics who maintain tandem-axle trailers with double-eye leaf springs. It’s suited for routine suspension servicing, pre-trip inspections, or when replacing visibly worn shackles, bushings, or fasteners. If you tow loads regularly and want a straightforward parts set to restore proper spring movement and reduce wear on suspension parts, this kit provides the common replacement pieces used in many tandem-axle setups.
