Replacing Equalizers on an Enclosed Haulmark Trailer

Published 12/17/2014

Question:

I am trying to find the correct replacement parts for my Haulmark enclosed trailer. As usual, the equalizer and the the connecting links have worn out and all needs replaced. How can I determine what parts are the correct parts that I need? Where can I find the info without taking everything apart to match it all up? I dont want to do this every year, and I noticed that you offer a grease-able replacement, that also has a rubber cushion to improve the ride and handling.

To replace your equalizer you will need to take a couple measurements:
A = Length from center of left-most eye to center of right-most eye
C = Diameter of center eye hole
D = Diameter of left and right eye holes (always 9/16 inch)
E = Height from center of bottom hole to center of top hole

See the diagram to the right.

This isn't typical of equalizers to wear out after a year. It seems to me your trailer could be overloaded causing the equalizers to breakdown quickly. Ensuring each axle is loaded appropriately as each spring carries 50 percent of the axle's weight rating. For example, if the axle rating is 3,500 pounds, each spring should be rated for 1,750 pounds.

I have included a FAQ and link to our equalizers for you as well.
