Racewill Tandem Axle Trailer Shackle Kit — 2-Pack 2-1/4" Straps, 9/16" Nylon Bushings, 3" Bolts, Corrosion-Resistant

Racewill Tandem Axle Trailer Shackles Kit is a complete 2-pack hardware set—shackle straps, bolts, nuts and nylon bushings—designed to replace worn components on dual-axle leaf-spring trailer suspensions.

When your tandem-axle trailer shows play, noise, or uneven ride height, worn shackles are often the cause. This Racewill kit supplies the common replacement parts needed to service double-eye spring tandem axle systems: two 2-1/4" shackle straps per side, 3" shackle bolts with locking nuts, and durable 9/16" nylon bushings. Everything is built for outdoor use and corrosion resistance to stand up to road and weather exposure.

How does this kit restore trailer suspension performance?

Replacing fatigued or corroded shackles removes excess movement and restores proper spring geometry, improving ride stability and reducing clunks. The included nylon bushings provide smooth pivoting and reduce metal-on-metal wear.

• Two 2-1/4" shackle straps per axle location for correct spring length.
• 9/16" nylon bushings (8 pieces) to cushion pivots and reduce noise.
• 3" shackle bolts with locking nuts (12 pieces) for secure attachment.

What parts are included and what are their specifications?

This kit contains the fasteners and fittings typically needed for a dual-axle tandem spring setup. All components are sized to fit double-eye springs and common tandem axle dimensions.

• 2 packs of 2-1/4" shackle straps (total pieces supplied for multiple mounting points).
• Eight 9/16" nylon bushings to absorb shock and provide a snug pivot.
• Twelve 9/16"-18 x 3" shackle bolts plus locking nuts for secure installation.

How durable and weather-resistant are these trailer shackles?

Racewill manufactures these parts from premium materials intended to resist corrosion and handle outdoor conditions encountered during towing. While they’re built for longevity, regular inspections are recommended because shackles take most of the suspension’s movement and wear.

• Corrosion-resistant finishes to reduce rust and extend service life.
• Heavy-duty straps and bolts sized for trailer load and dynamic stresses.
• Nylon bushings that resist moisture and maintain smooth operation.

What should I check before installing this shackle kit?

Measure your existing shackle strap length and bolt diameter to verify compatibility, and inspect the spring eyes and hanger mounts for cracks or excessive wear. Proper torque on the bolts and use of the supplied locking nuts help prevent loosening under load.

• Confirm 2-1/4" strap fits your spring and hanger spacing.
• Verify 9/16" bolt diameter matches current mount holes.
• Inspect surrounding suspension components for damage before reassembly.

Who this is for: This Racewill Tandem Axle Trailer Shackles Kit is aimed at trailer owners, DIY mechanics, and fleet maintainers who need a convenient, full replacement pack for double-eye spring tandem axle systems. It’s ideal for boats, utility trailers, RVs, and any dual-axle trailer that requires reliable shackle straps, bolts, and bushings to restore safe, noiseless suspension function.
