1. Sway Control Brackets:

Rigid trailer attachments work with friction sway control to combat trailer sway. Brackets are height adjustable to control the amount of weight distribution tension on the spring arms.

2. Spring Arms:

The spring arms serve two purposes. When raised onto the sway control brackets they transfer trailer tongue weight evenly to the tow vehicle. They also work with the friction sway control to reduce trailer sway.

3. Downward Pressure:

Downward pressure from trailer tongue increases friction sway control. Trailer hitch ball mounts here.

4. Upward Pressure:

Sway control brackets distribute weight by maintaining upward pressure on spring arms. The amount of pressure on the spring arms is a factor of trailer tongue weight and vehicle suspension. The friction sway control utilizes this pressure to control trailer sway.

5. Friction sway control:

Friction is enhanced by downward pressure from trailer tongue and upward pressure on spring arms. These opposing pressures come together to create an unequaled sway control system.

Installation Instructions

Weight distribution:
The Equal-i-zer helps distribute the weight of your trailer. Keeping your weight distributed puts more weight on your front wheels and improves your steering control and ride quality.

Sway Control Capabilities:
The integrated sway control keeps your trailer in line and helps eliminate the white knuckles associated with passing trucks and cross-winds. Unlike conventional sway controls, the Equal-i-zer allows you to back up your trailer as usual without disengaging the sway control.

Vehicle Compatibility:
The Equal-i-zer® works flawlessly with boat trailers, trailers with surge brakes, utility trailers, horse trailers, cargo haulers, pole (or single) tongue and many other trailer types. The standard trailer brackets can fit up to a 6" trailer frame. Also available are 8" and 10" brackets to accommodate newer lightweight aluminum or tall I-beam trailer frames. The unique design of the sway control brackets allow flexible placement on the trailer frame. This means that tongue jacks, propane tanks, and other obstacles are not a problem.

I just took a 1000 mile trip using my new hitch pulling a 10,000 pound trailer and can not say enough about how pleased I was. It did everything that was advertised and more. There was no sway when we were passed by semis or had cross-winds. I could not believe the difference in this hitch and my old hitch, which I thought was the top of the line. I have recomended this hitch to everyone I know. Also I was pleased at how easy the hitch was to hook up and take off. I am 81 years old and have a bad back, I put this hitch on and took it off with no problem. Thanks for a great hitch. Kyle Estes
Ps: Feel free to use my review

Installation of the Equal-i-zer hitch took less than one hour without any special tools or outside help. I would recommend this hitch to anyone needing a weight distribution and sway control unit for any kind of towing. Attaching and detaching hitch and trailer is very simple and easy , taking only a couple of minutes for each.
