This is a suspension U-bolt, typically used to clamp a leaf spring stack to a truck or trailer axle.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
The bolt is shaped like a U, wrapping around the axle tube, with its threaded legs passing through a spring plate to secure the entire assembly. U-bolts like this are replaced whenever leaf springs are serviced, if the old bolts show signs of stretching, corrosion, or fatigue cracking, or anytime the axle-to-spring connection is disassembled.
