When measuring a trailer equalizer take your tape measure and start from the center of the left bushing eye. Don not measure to the top eye that connects to the hanger but to the right eye directly across from the one you started at. Measuring to the center of this busing as well you can correctly identify an equalizer with this measurement. To put it simple measure from the center of both bushing sockets that connect to the shackles.

When measuring a trailer shackle measure from the center of bolt hole to the center of bolt hole. This measurement will allow for a correct replacement to be identified. The reason for measuring from the center of these holes is because it's more important to have the same distance between the eye of the spring and the equalizer, than having the same length of shackle but the bolt holes are spaced differently.

When measuring a bolt for your trailers suspension measure the total length starting from the top bottom of the threads and stopping at the top of the head. Bolts that are right around 2 inches in length are always found on double eye spring suspension set-ups. They can also be found on slipper spring suspension. Bolts that measure 2-1/2" are only found on slipper spring suspension set-ups.
