It includes four Grade 8 forged semi-round U-bolts, along with matching nuts and washers. The kit clamps the leaf spring stack to the axle housing, maintaining proper axle alignment and suspension integrity. It is typically replaced during spring service or when original U-bolts are found stretched, corroded, or no longer holding proper torque.
