Dayton Parts 361-374 Grade 8 Round U-Bolt Kit | 7/8" x 3-1/16" x 14-1/2"

Product Overview

Secure your vehicle or trailer suspension with the heavy-duty reliability of the Dayton Parts 361-374 Leaf Spring Axle U-Bolt Kit. Backed by more than a century of automotive experience and a dedicated team of product experts in the United States, this standard replacement kit delivers fleet-grade structural integrity when you need it most.

The components in this premium kit are engineered from high-quality, high-tensile steel designed to securely clamp the leaf spring or leaf spring bundle directly to the underside of a vehicle or trailer axle. Suspension U-bolts endure punishing vertical shock loads and axle twisting stresses; over time, standard hardware can stretch or corrode, leading to dangerous axle shifting and leaf spring breakage. Engineered to standard replacement specifications, this gray, universal-fit steel kit features a robust Grade 8 rating and fine-thread pitch to ensure maximum clamping force, reliable performance, and an extended service life under severe vocational loads.

⚠️ Fitment Warning: U-bolts should never be reused once torqued and removed. Always replace your suspension hardware in axle sets. Carefully review your leaf spring dimensions, axle diameter, and application details below to select the right size U-bolt kit for your suspension layout.
