2 Pack Trailer Shackle Kit for Tandem Axle Double Eye Springs

In this review the 2 Pack Trailer Shackle Kit for Tandem Axle Double Eye Springs is evaluated as a straightforward, no-frills replacement kit for trailers with 3,500 lb to 7,200 lb axles. The bottom line: this kit is best for owners who need a complete, corrosion-resistant set of shackles and hardware to maintain tandem axle suspension, and its biggest advantage is that it supplies all commonly worn components in one purchase, reducing downtime during routine maintenance.

Key Features

• Tandem axle compatibility: Designed specifically for double eye spring tandem axle suspension, the kit fits common trailer setups and simplifies part matching.
• Full hardware set: Includes shackle straps, nylon bushings, bolts and locking nuts so users receive everything needed for a standard replacement without extra trips to the parts store.
• Nylon bushings: The kit provides eight 9/16' nylon bushings which reduce metal-on-metal wear and help maintain smoother articulation under load.
• Robust materials: Components are made from premium, corrosion-resistant materials intended for outdoor use and exposure to road conditions.
• Multiple bolts included: Ships with twelve 9/16'-18 x 3' long shackle bolts and locking nuts to ensure secure fastening and spare parts for multi-axle setups.

Who It's For

This kit is for trailer owners and maintenance shops that service tandem axle trailers with double eye springs and axles in the 3,500 lb to 7,200 lb range. It suits DIYers who prefer a single packaged solution covering both shackles and necessary hardware for routine suspension upkeep.

Those who should look elsewhere are owners of single-axle trailers, trailers with different spring eye dimensions, or buyers seeking specialty stainless hardware for extreme marine environments; if bolt metallurgy and anti-seize concerns are critical, consider sourcing upgraded bolts separately.
