Keeping the axle firmly attached to the leaf springs is key for stable towing. This U-bolt plate is made to work with 1-3/4" square trailer axles and 1-3/4" wide leaf springs, giving you a tight, secure connection that holds steady mile after mile. It’s the right match for setups rated at 2,000 lbs and keeps the suspension parts aligned and working together the way they should.
A loose or shifting axle can throw off your ride and wear parts unevenly. This plate uses two 9/16" diameter square U-bolts (sold separately) to clamp the axle and spring together with even pressure across the mount. Once tightened down, the assembly resists movement and keeps the load balanced through bumps, curves, and rough roads.
Getting the right parts to line up the first time makes any repair smoother. This plate is designed to pair directly with standard 9/16" U-bolts, so everything fits cleanly without modification. The straightforward setup means you can bolt it in place and get back on the road with a solid suspension connection you can trust.
