U-bolts secure the trailer axle to the leaf spring pack and spring seat, maintaining proper alignment under load. Correct inside width and depth are critical to ensure the axle tube seats fully without binding.
Always verify axle tube diameter, required inside width, thread size, and thread length before installation.
