Loose hardware can let the axle shift and throw off your suspension. This kit uses 3/8" diameter U-bolts with a 2-1/2" threaded section that clamps your 1-1/2" square axle solidly to the leaf springs. Torque them to 30–50 ft-lbs for a snug, lasting hold that keeps the undercarriage stable mile after mile.
Boat and snow trailers see plenty of water and road grime. The zinc-plated bolts and galvanized plates in this kit resist rust and corrosion so the connection stays clean and secure. Even after repeated dunking or winter storage, the coating keeps the hardware from seizing or flaking apart.
Getting the right match for small-axle setups is simple with this kit. The U-bolts measure 3-5/16" long x 1-5/8" wide inside, 3-5/8" long x 2-3/8" wide overall, and pair with 3-3/8" x 3" plates drilled for 1-3/4" springs. Everything lines up so the axle seats straight and the springs move freely.
No need to hunt for extra pieces—this package comes ready to go with four U-bolts, two plates, and eight 3/8" hex nuts with washers. It’s a direct fit for 2,000-lb square axles, giving you everything needed to mount or refresh the suspension connection in one shot.

Working very well, I use the trailer weekly, and it is holding up well. I have trailered many hundreds of pounds with no issues.
