The kit includes U-bolts with a 1-1/4-inch diameter, 4-inch inside width, and 14-1/2-inch leg length. It is typically replaced when original U-bolts become stretched or corroded, or during suspension repairs to maintain proper torque and clamping force. It is intended for Mack trucks that use this specific U-bolt configuration.
