Heavy Duty Truck Springs

How to measure a U-bolt

First, determine if the U-bolt is round, semi-round or square. Next, measure the diameter of the rods (this can easily be done with a socket wrench). Then measure the width of the space between the rods and the length of the bolt from top to bottom.

How to identify a spring

You can identify your spring in two ways: by locating the O.E.M. part number or by determining the spring’s dimensions.

To locate the part number on a full taper spring, look on the end of the first leaf. You may also find it on the side, bottom or top of the clip. On multi-leaf springs, numbers are usually on the side, bottom or top of the clip, and sometimes on the bottom of the last leaf by the center bolt, or on the end of the shortest leaf. Trailer leaf spring numbers are found on the outside of the hook.

  • Main Leaf Length: For an eye-to-eye spring, measure from the center bolt to the center of the eye along the arch. For an eye-to-slipper spring, measure from the center of the eye to the end of the slipper along the arch. For a slipper-to-slipper spring, simply measure from end to end along the arch. For a camel back spring (Mack Trucks only) measure from the center bolt to the end of the main leaf in both directions along the arch. For a single point spring, measure from the center bolt to the end of the main leaf in both directions along the arch. The end hole size and distance from the center bolt must be checked also.
  • Leaf Spring Width: Measure at the center bolt from side to side across the leaf.
  • Pack Thickness: This measurement is taken from the center bolt down the side of the spring and includes all leaves, tow eyes, shock eyes and pads.
  • Leaf Spring Arch: For an eye-to-eye leaf spring, use a straight edge to mark the center of the eyes and measure the arch at the center bolt. Be sure to measure to the top of the main leaf and do not include pads or spacers. For an eye-to-slipper leaf spring, use a straight edge to mark the center of the eye and top of the slipper and measure the arch at the center bolt. For a slipper-to-slipper leaf spring, place a straight edge on the top of the slipper ends and measure the arch directly over the center bolt. For a camel back leaf spring (Mack Trucks only) or a single point leaf spring, mark the top of the main leaf in both directions with a straight edge, then measure the arch at the center bolt.
  • Eye Leaf Length: Measure from the center of the eye to the center bolt along the arch.
