Weight Distribution Setup

Use the following guidelines to set up and adjust your Equal-i-zer hitch for weight distribution. Good weight distribution is a critical component of the Equal-i-zer hitch setup. A hitch that is set up poorly for weight distribution will not perform like one that is set up well. Every tow vehicle and trailer combination will react differently to weight distribution.

To correctly set up weight distribution you must take 3 sets of measurements on your tow vehicle.  First, measure without the trailer coupled.  Next, measure with the trailer coupled, but with no weight distribution.  Third, measure with the trailer coupled and the weight distribution bars tensioned.

Start by measuring the distance from the ground to the wheel well directly above the front axle with the trailer uncoupled. See Figure 14. Ideally, measure both driver and passenger sides, and use the average of these two.

Record this on Line A of the weight distribution setup table.

Back the tow vehicle to the trailer and lower the coupler onto the ball.  Lock the coupler and retract the tongue jack until it raises off the ground about 1” so that the full tongue weight of the trailer is resting on the hitch.

Measure the tow vehicle height again exactly above the front axle, to the same point that you measured to earlier when uncoupled. Record this on Line B of the weight distribution setup table on page 16.

With the tow vehicle still coupled to the trailer, use the tongue jack to lift both vehicles until you can swing the spring arms into place over the L‑brackets. See Figure 15. Then retract the jack.

Assemble the snap-up lever. See Figure 16. Do not try to lift the spring arms into place with only the hook part of the lever.

If you reach the top of the jack before the spring arms will swing into position, you can use the Snap-up Lever to lift the spring arms up and onto the L-brackets.  Use the L-pins and clips to secure the spring arms on the L-brackets. See Figure 17-18.

With the spring arms resting on the L-bracket and the trailer and tow vehicle in line with each other, check to make sure that there is a minimum of 3” from the end of the spring arms to the center of the link plates. See Figure 19. If necessary, unload the spring arms, then move and re-tighten the sway bracket assembly.

NOTE: Refer to Appendix B, “Weight Distribution Adjustments” on page 28 for a more detailed description of factors that influence weight distribution setup and adjustment.

With the trailer coupled and weight distribution engaged (spring arms in place and jack retracted), re-measure the front wheel well height exactly as done before for lines A and B.  Record this new measurement on Line Cof the weight distribution setup table on page 16.
