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

Racewill Tandem Axle Trailer Shackles Kit is a complete two-pack hardware set designed to replace worn shackle straps, bolts and bushings on double-eye spring tandem axle trailer suspensions.

When your trailer suspension shows play, squeaks or uneven ride, the shackles and their fasteners are the parts that take the most stress. This Racewill kit contains the typical components needed for routine service or repair on tandem-axle, double-eye spring systems — two shackle straps per side, matching bolts, locking nuts and nylon bushings — all made to resist outdoor corrosion and repeated movement.

How will this kit fit my tandem-axle trailer?

These shackle straps are sized for 2-1/4" leaf spring eyes and the kit includes 9/16" diameter hardware commonly used on dual-axle trailers. If your trailer uses double-eye springs and standard 9/16" pins, this set is ready to install without modification. Always measure your existing straps and bushings to confirm compatibility before purchase.

• Includes two 2-1/4" shackle straps per pack (fits 2-1/4" spring eyes)
• 12 pieces of 9/16"-18 x 3" shackle bolts for multiple points of attachment
• Comes with 8 nylon bushings sized 9/16" for smooth pivoting
• Locking nuts supplied to secure bolts under vibration

What materials and corrosion protection are used?

Components are made from durable metals treated for outdoor exposure; the bolts and straps resist rust and wear typical of road and weather conditions. The nylon bushings reduce metal-on-metal friction and help prevent premature wear in moving joints, making the kit suitable for regular trailer use. For very salty or marine environments, additional corrosion control like grease or stainless upgrades is recommended.

• Heavy-duty metal shackle straps designed for load and movement
• Corrosion-resistant finish to extend service life outdoors
• Nylon bushings to reduce friction and noise at pivot points
• Locking nuts to maintain clamp under vibration and load

How easy is installation and what tools will I need?

Installation requires basic hand tools and a safe way to support the trailer axle or frame while you work. Typical tasks include removing old shackles, pressing out worn bushings, aligning new straps and tightening the provided bolts to appropriate torque. If you’re not comfortable supporting the axle or torquing suspension bolts, consult a mechanic.

• Common tools: wrenches or sockets, jack stands or axle support, lubricant for bushings
• Set includes all bolts, nuts and bushings to complete installation at multiple mounting points
• Simple replacement for like-for-like shackle sizes — no modification usually required
• Recommended: torque wrench to secure bolts to manufacturer specs

What maintenance should I do after installing this kit?

Check the shackles periodically for play, rust, and bushing wear — shackles are the moving parts that typically wear first. Reapply grease or lubricant to the bushings as needed to reduce noise and friction, and inspect bolts for loosening after initial road use. Regular inspection helps avoid unexpected suspension failures and keeps the trailer riding smoothly.

• Inspect for looseness and bushing degradation every few hundred miles
• Lubricate bushings periodically to prolong service life
• Tighten locking nuts if any movement is detected after first use
• Replace individual components from the kit as they show wear

Who is this for: The Racewill Tandem Axle Trailer Shackles Kit is aimed at trailer owners, DIY mechanics and fleet maintainers who need a ready set of replacement parts for dual-axle, double-eye spring suspensions. It’s useful for routine maintenance, pre-trip inspections, or restoring suspension components on utility, boat, equipment and cargo trailers where 2-1/4" shackle straps and 9/16" hardware are specified.
