【Wide Range of Applications】This trailer axle shackle kit is a trailer suspension kit for double-eye spring tandem axle suspensions (3,500–7,200 lbs axles), compatible with utility trailers, boat trailers, and cargo trailers. It's for trailer chassis parts replacement/repair—including trailer suspension parts and utility trailer parts—in home garages and professional workshops, paired with trailer spring hanger or trailer leaf spring hanger
【Sturdy Construction】Made of steel, the trailer shackles here are built for strength and longevity on regular roads. Its anti-rust coating keeps key trailer parts performing in wet or saltwater, and works well as a trailer axle kit component
【Fit Size】The trailer equalizer (from this trailer equalizer kit) has 7-3/4'' hole spacing. This trailer axle shackle kit's shackle strap is 4.38'' long with 3-1/8'' (3.12'') hole spacing. Bolts are 3-3/8'' long; nylon trailer leaf spring bushings (trailer spring bushings) have 9/16'' I.D. and 11/16'' O.D. Both bolts and nuts use 9/16''-18 threads
【Complete Accessory Set】This trailer axle kit includes 2 long triangular trailer equalizers, 8 shackle straps, 8 trailer leaf spring bushings, 14 shackle bolts, and 14 locking nuts(These lock nuts compress from both ends, causing the center threads to expand slightly. This deformation in the threads helps secure the nut firmly in place). This all-in-one package provides necessary trailer parts for installation or replacement
【Quality and Performance】The trailer shackle kit meets trailer operation demands. Materials and finish boost wear and corrosion resistance for trailer suspension parts and other essential trailer parts
