If you're working on boat trailer repairs or building a new trailer, this galvanized U bolt kit has all the hardware you need to mount your axle to the leaf springs.

The kit includes four square U bolts, two galvanized 4-hole mounting plates, plus eight nuts and lock washers - everything for a complete single axle installation.

The hot-dipped galvanized coating is crucial for preventing rust, especially if you're using your trailer in saltwater environments.
The U bolts are sized specifically for 2x2 inch square axles, which are common on many boat trailers.

Each U bolt measures 1/2 inch in diameter with a 2 inch inside width and 5-1/4 inch inside length.

This setup works with both 1-3/4 inch and 2 inch wide leaf springs, making it compatible with 2,220 lb or 3,500 lb trailer axles.
Installation is straightforward - you position the U bolts around your axle, place the mounting plate on top, and secure everything with the included nuts and lock washers.
The galvanized finish isn't just for looks - it seriously extends the life of your trailer hardware by resisting corrosion from road salt, marine environments, and weather exposure.

Whether you're fixing up an old trailer or building a new one, this complete kit saves you from hunting down individual parts and ensures everything matches perfectly.
