Equal-i-zer 400/4,000 4-Point Sway Control Hitch Description

Equal-i-zer® offers a unique two-in-one design that combines weight distribution with sway control in one easy to use unit. The simple design has a built-in sway control to help minimize risk of sway problems caused by passing vehicles, cross winds, and other towing hazards. Equal-i-zer® is safe, simple, and easy to use.

Towing a trailer doesn't need to be a tense and fearful experience. It doesn't have to be difficult. It doesn't have to be filled with safety concerns and woes. The right hitch makes all the difference. It can turn a good trailer into a great trailer...and a great experience. Simply put—the Equal-i-zer® is the most affordable and best way to trailer.

Equal-i-zer® brand hitch works to help control trailer sway with 4-Point Sway Control™. Equal-i-zer®'s 4-Point Sway Control™ is a combination of 4 positive friction areas that work together to combat trailer sway. 4-Point Sway Control™ is superior to “add-on” friction bars or cam-type systems that are used with conventional or chain-style weight distribution hitches.

Without weight distribution the weight of the trailer pushes the rear of the tow vehicle down. Hazards associated with driving a trailer without weight distribution include loss of steering control, braking difficulties, and hitch dragging. Equal-i-zer® brand hitch combats such hazards by providing proper weight distribution. With Equal-i-zer® the trailers' weight can be safely and easily distributed to all axles of the vehicle.

Works well, a few things to think about
The Equal-i-zer works as advertised, and wasn't difficult to assemble. I had a hard time finding a ball to fit the hitch. It requires a ball with a 1.25" dia. shank (or smaller diameter + bushing) that's not more than 2.275" long. I found a 1.25" shank, but could not find one shorter than 2.75". I ended up sawing the last .375" off the 2.75" shank. It's important that the ball shank isn't too long, because if it is, the spring bars of the hitch will hit the shank when turning. I'd recommend purchasing a ball from Equal-i-zer along with the hitch. By the way, the 1.25" thread on the ball takes 450 ft-lb torque.

I use the hitch with a classic car towing a small travel trailer. The hitch works fine for leveling the car. It does reduce sway (yaw), but for my vehicle, that's not a big problem anyway. I haven't had to readjust the hitch due to trailer weight distribution changes, but I could see the need arising. In that case, it will be necessary to have tools (various wrenches + a tape measure) to readjust. I keep the necessary tools in a tool bag that goes along with the trailer.

After a couple hundred miles the hitch makes a fair amount of noise when turning. That's normal, resulting from the friction that provides the yaw damping. The instructions say that grease could be used, but that would be a mess. I'd like to use the plastic "sway bracket jackets" sold by Equal-i-zer (part no. 95-01-5150), but they don't work with the 4000 lb setup, which I have (only works on 6K to 14K models).

Each spring bar is held into the hitch using a "socket pin" with a "hairpin" clip through the end to keep it from falling out. The hairpins are convenient, but I'm not sure that I trust them to stay put. I carry bolts and nuts in case the hairpins get lost. I keep an eye on them, because if a hairpin falls out, the socket pin might work out, and then the spring bar would land on the road. It could really use a more positive retention system.
  • Works well to distribute load
  • Should have more secure approach to socket pin retention, and a solution for noise reduction on 4K models

I installed it myself..
The intructions for installation were great. You will need a torque wrench cabable of 250 ft-lbs. The manually has some torque differences, but I figured it out, It is a well built product. I got it mostly for weight distribution which it seems to do.

Works Great!
I bought this hitch for use with my Lance 1575 Travel trailer and my Toyota Tacoma Tow vehicle. It brought the front end of the truck down to level, and eliminated 90% of the side sway in the trailer. Easy to install and good directions. Worth every penny!

One note of caution; The hitch ball socket is 3/4" drive. I couldn't use it!
