Uneven roads can make a trailer bounce and sway, throwing off balance and comfort. The curved 7-3/4" long equalizers in this tandem-axle hanger kit keep that in check by distributing the impact of bumps evenly between both axles. That means smoother motion and steadier handling when towing. The equalizers let the springs move together instead of fighting each other, helping the suspension absorb the rough stuff instead of transferring it to the frame.
Weak or worn hangers can make the suspension feel loose or uneven. The 3-1/4" tall front, center, and rear hangers in this kit restore a strong connection point for your double-eye leaf springs. Each hanger welds securely to the frame for a permanent installation that won’t shift under load. They give you the right geometry for even spring travel and consistent clearance between the trailer frame and the axles—about 4-1/2" to 5" depending on axle size.
Suspension parts take a beating mile after mile, so every piece in this kit is built to match and last. Eight 2-5/8" long shackle straps connect the springs to the equalizers so they can pivot freely. Fourteen 3" x 9/16" bolts with matching locknuts lock it all together without binding, keeping your suspension aligned over time. It’s a complete hardware set for installing four double-eye leaf springs (sold separately) on a tandem setup.
Whether you’re restoring a work trailer or building one from scratch, this kit is ready for common tandem axle setups rated from 2,000 lbs up to 7,000 lbs per axle. With correctly spaced hangers—typically around 29-1/2" between front and center and between center and rear—it sets you up for proper axle placement and dependable suspension geometry once welded in place.
