iBroPrat Trailer Shackle Kit for Double-Eye Tandem Axles, 3,500-7,200 lb — Complete Hardware, Black Oxide

The iBroPrat Trailer Shackle Kit is a complete hardware set designed to replace worn shackle straps, bolts, bushings and equalizers on tandem-axle double-eye leaf spring suspensions.

Whether you're rebuilding a trailer suspension after years of use or keeping spares for roadside repairs, this kit groups every fastener and component you need into one purchase. It removes the hassle of hunting down matching shackle straps, nylon bushings, bolts and nuts by supplying a matched complement for most common double-eye spring tandem axle systems.

How many parts are included and what sizes should I expect?

The kit arrives as a full replacement set so you can service both sides of a tandem-axle suspension without missing pieces. Each quantity and dimension is selected to match typical factory shackle layouts.

• 8 shackle straps sized 2-9/16"
• 2 triangle equalizers at 7-3/4" long
• 8 nylon bushings (9/16")
• 14 shackle bolts: 9/16"-3 x 3" long
• 14 self-locking nuts: 9/16"-18

Will these parts fit my trailer’s double-eye springs?

This set is intended for many standard tandem-axle double-eye spring setups commonly rated in the 3,500–5,200 lb range and can work with similar configurations up to 7,200 lb when matched correctly. Confirm the bolt hole diameters and spring-eye spacing on your trailer before ordering to ensure compatibility.

• Designed for double-eye leaf springs used on tandem axles
• Check that your spring eye and hanger use 9/16" hardware
• Compare equalizer length (7-3/4") to your current part
• Ideal for common trailer service and light-to-medium duty rigs

What materials and finishes are used, and how durable are they?

Components are manufactured from high-hardness, wear-resistant metals and finished with a black oxidized coating to reduce corrosion and improve lifespan in outdoor conditions. The kit’s nylon bushings help dampen metal-on-metal wear and simplify installation.

• High-quality steel construction for straps, bolts and equalizers
• Black oxidized finish for rust resistance
• 9/16" nylon bushings for reduced friction and noise
• Self-locking nuts to prevent loosening under vibration

How does this kit speed up repairs and reduce downtime?

By supplying the complete set of fasteners and wear pieces, the iBroPrat kit eliminates multiple trips to suppliers and mismatched parts that stall repairs. You can replace both sides of a tandem arrangement in one session and get the trailer back on the road faster.

• Includes every shackle strap and bolt needed for tandem axle service
• Pre-matched sizes avoid compatibility issues
• Extra bolts and nuts cover broken or corroded fasteners
• Nylon bushings are ready-installed to speed assembly
