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.
It contains two 7/8-inch-diameter, 14-inch-long U-bolts with 3-1/2 inches between the legs, along with hardened washers and deep nuts. U-bolts clamp the leaf spring pack to the axle, maintaining alignment and clamping force. They are typically replaced when a spring or axle is serviced, or when the original U-bolts have stretched or threads are damaged.
