Question:
I have a 20ft flat deck trailer that had the axles welded to the frame. I want to put springs on and Im not sure of the spacing for the spring mounts and equalizer. The kit I bought has springs with a length of 25 1/4 center to center, 4 small mounts at 1 1/2 top to center, and two large mounts at 3 3/16 top to center, and equalizer a at 8inch center to center, shackles are 3 1/4. Can you help me determine the spacing I need. The tires are 225/75R15

Expert Reply:
I would need to know the axle capacities to be sure but I can venture an educated guess. The only tandem axle double-eye leaf spring hanger kit we have that includes 8 inch equalizers is # APT1. With this kit, the center of the forward hanger to the center of the rear hanger would be 29-1/2 inches. It is the same from the center hanger to the rear hanger on center. That would make the center to center distance between the 2 axles 34 inches. I have included a picture showing the measurements for you.
