Racewill Tandem Axle Trailer Shackle Kit 2-Pack — 2-5/8" Straps, 9/16" Bolts & Nylon Bushings for Dual/Triple Axles

Racewill Tandem axle trailer shackle kit is a complete 2-pack repair and replacement set that includes 2-5/8" shackle straps, 9/16" nylon bushings, 3" shackle bolts and locking nuts for dual- and triple-axle suspension systems.

Replace worn or noisy shackles with this ready-to-install Racewill kit designed for double-eye spring tandem axle suspensions. The set supplies the high-wear components that connect the leaf spring to the trailer frame so you can restore safe, quieter towing without hunting for individual parts. All pieces are made from corrosion-resistant materials so they stand up to outdoor use and road exposure.

How does this kit fix common trailer suspension problems?

Shackles absorb lateral movement and the vertical travel that comes from springs, so worn shackles lead to excessive play, noise, or uneven handling. Swapping in new straps, bolts, and bushings reduces slop at attachment points and helps the spring-seat geometry return to factory alignment. Installation addresses the most common source of squeaks and observable spring movement.

• Includes 2 packs of 2-5/8" shackle straps suitable for tandem axle setups
• Comes with 8 nylon 9/16" bushings to replace degraded rubber/metal pieces
• Supplies 12 shackle bolts (9/16"-18 x 3") and locking nuts for secure fastening

What exactly is included and are the parts compatible with my trailer?

The Racewill kit bundles the components most often replaced together so you won’t need extra trips to the hardware store. These parts are intended for double-eye spring tandem axle suspensions and compatible with most dual-axle systems and all triple-axle configurations that use 2-5/8" straps and 9/16" fasteners. Confirm your trailer’s shackle strap length and bolt diameter before ordering.

• 8 pieces of 9/16" nylon bushings for long-lasting pivot and noise reduction
• 8 pieces of 2-5/8" shackle straps matched to common tandem axle spring mounts
• 12 pieces of 9/16"-18 x 3" bolts with locking nuts for complete mounting hardware

How difficult is installation and what tools are required?

Installation is straightforward for anyone comfortable with basic trailer maintenance: lift and support the trailer, remove old shackles, and replace with the supplied straps, bushings, bolts, and nuts. Typical hand tools are sufficient and the included locking nuts eliminate the need for specialty locking hardware. If corrosion has seized old bolts, penetrating oil and a breaker bar may be necessary.

• Basic tools: jack stands, socket set, torque wrench, penetrating oil if bolts are rusted
• Typical install time: 45–90 minutes per shackle pair depending on access and condition
• Locking nuts included to ensure a secure, vibration-resistant connection

What are the material and durability features of these components?

Racewill manufactures this kit from durable, corrosion-resistant materials meant for exterior use and the stresses of towing. Nylon bushings reduce metal-on-metal contact and provide smoother pivot action, while plated straps and bolts resist rust. Together, the components help extend service life compared with worn original hardware.

• Corrosion-resistant straps and bolts to resist road salts and weather
• Nylon bushings for quieter operation and reduced wear on mounting points
• Complete hardware set to replace most high-wear shackle assemblies

Who is this for? The Racewill Tandem Axle Trailer Shackles Kit is ideal for trailer owners, fleet managers, and DIY mechanics who need a dependable replacement set for double-eye spring tandem axle suspensions. Choose this kit if you want a complete package of straps, bushings, bolts, and locking nuts to stop suspension noise, restore proper spring attachment geometry, and avoid sourcing individual parts.
