Racewill 2-Pack Trailer Shackle Kit for Tandem-Axle Double-Eye Springs — Corrosion-Resistant Straps & Nylon Bushings

Racewill 2 Pack Trailer Shackle Kit is a complete tandem-axle hardware set designed to replace worn shackles, bushings, bolts, and nuts for double-eye spring trailer suspensions rated 3,500–7,200 lbs per axle.

When suspension shackles show play or corrosion they affect ride stability and safety. This Racewill kit bundles the most commonly worn suspension pieces—shackle straps, nylon bushings, and long shackle bolts with locking nuts—so you can service both ends of a tandem-axle trailer quickly. Components are made of robust, corrosion-resistant materials intended for outdoor use and routine towing environments.

How will this kit fit my tandem-axle double-eye spring setup?

The kit is built specifically for tandem axle trailers using double-eye leaf springs. Each kit includes parts sized to fit standard 9/16" shackle bolts and 3 1/8" shackle straps commonly found on 3,500–7,200 lb axle configurations. Verify your trailer’s bolt diameter and eye dimensions before ordering to ensure compatibility.

• Includes 8 nylon 9/16" bushings for proper wear clearance and noise reduction
• 8 shackle straps, each 3 1/8" long to match common double-eye spring setups
• 12 shackle bolts 9/16"-18 x 3" long to handle through-bolt connections
• 12 locking nuts to secure bolts and resist loosening under vibration

What maintenance or benefits can I expect after installing new shackles?

Replacing worn shackles restores intended suspension travel and alignment, reduces clunking noises, and improves load transfer through the leaf springs. Regular inspection and timely replacement of shackle components prevent accelerated wear on other suspension parts and make trailer handling more predictable.

• New nylon bushings reduce metal-on-metal contact and dampen vibration
• Fresh shackle straps eliminate bent or stretched hardware that misaligns springs
• Long bolts and locking nuts provide secure clamping and resistance to loosening

How durable are the parts for outdoor, towing, and storage conditions?

Parts are manufactured from durable metals with corrosion-resistant finishes and include nylon bushings that tolerate moisture and road debris. They are intended for routine towing conditions, storage outdoors, and seasonal exposure, but like all suspension components they should be inspected periodically for corrosion, deformation, or wear.

• Corrosion-resistant metal construction for longer outdoor life
• Nylon bushings resist moisture absorption and reduce noise
• Locking nuts help maintain tightness under vibration and travel loads

What’s included and how many axles will one kit service?

This Racewill kit supplies enough hardware to service a tandem-axle trailer (two axles) that uses double-eye springs. The parts count covers multiple shackle locations so you can replace both front and rear shackles where needed.

• 8 shackle straps and 8 nylon bushings—enough for both sides on tandem axles
• 12 bolts and 12 locking nuts to secure all shackle attachments
• Designed to cover commonly worn components across two axles

Who is this for: The Racewill 2 Pack Trailer Shackle Kit is aimed at trailer owners, fleet maintenance techs, and DIY mechanics who need a complete replacement set for tandem-axle double-eye leaf springs. If you tow regularly, store trailers outdoors, or are restoring a trailer with worn suspension links, this kit provides the common fasteners and bushings required to restore proper shackle function. Always confirm bolt diameter and spring eye size before installation and follow vehicle safety procedures during replacement.
