It includes two 1-1/4-inch diameter, Grade 8 steel semi-round U-bolts with fine threads, along with four high nuts and four thick washers. The kit is primarily used on Mack truck suspensions but can fit any application requiring 4-inch inside width and 17-1/2-inch leg length. U-bolts should be replaced whenever the suspension is serviced, if the bolts are stretched, corroded, or have lost proper torque, because they are critical for maintaining axle alignment and safe clamping force.
