3/4″ Round Truck U-Bolts – High Tensile

3/4″ truck round u-bolt thread is a UNF length 75mm long. The 2 u-bolts in the image are illustration only. Price per u-bolt.

Primarily, the truck u-bolts provide the clamping force required to clamp the leaf spring and axle firmly together.

Proper clamping of the spring by the truck u-bolts provides the desired spring stiffness and contributes to maintaining the vehicle ride height and handling characteristics as originally specified for the vehicle.

Rusty or damaged u-bolts require replacing from time to time. Checking the u-bolts around your axle and spring assemble is easy. Just select the correct size socket, crawl under the rig and check or adjust the u-bolt nuts. If they are cross-threaded and will not tighten, then you need to replace the u-bolt.

It is important to check tightening at the first service to ensure correct tightness.
