Leaf Spring: U-Bolt Kit 5 1/2"

U-Bolt Kit for 3,500 lb Round Trailer Axles - 5-1/2" Long

This U-bolt kit is designed to securely mount 3,500 lb round trailer axles to leaf springs, providing a stable and safe suspension connection. It fits 2-3/8" diameter round axles and uses 5-1/2" long, 1/2" diameter U-bolts to clamp the axle firmly to the springs.
Built with Grade 5 steel hardware, the bolts resist stretching and maintain proper clamping force under load. The included plates are sized for 1-3/4" wide leaf springs, which is the most common spring width on 3.5K axle setups. When torqued to 45-70 ft-lbs, this kit helps keep the axle properly seated and aligned.
The kit includes U-bolts, plates, and nuts, providing the essential components needed to install one axle. Ideal for utility, cargo, and equipment trailers using 3,500 lb round axles.
