Review of the Equal-i-zer Weight Distribution System with 4 Point Sway Control Review

Today we're going to be taking a look at the Equal-i-zer weight distribution system with a 4-point sway control. It includes an adjustable weight distribution shank. It has a 10,000 pound gross trailer weight and a 1,000 pound tongue weight, Part Number EQ37100ET. You've decided you need a weight distribution system. The Equal-i-zer weight distribution system uses steel-on-steel friction to help prevent and correct trailer sway. The sway control brackets ensure that your trailer stays in line with your tow vehicle. Our spring-bars flex appropriately over uneven terrain for a more controlled and even ride without bounce. The system includes the head assembly, though you will have to provide your own hitch ball, and you need to make sure that it has an inch and a quarter shank.

It uses a traditional washer system to provide tilt in the head. The more tilt in the head, the more lift in the tongue weight. Because it uses the 4-point sway control, there are no chains. The spring-bars are easily installed with the included lift handle. The whole thing is made out of a dipped steel construction, so it's going to be durable and resist rust and corrosion. As with all weight distribution systems, it helps your tow vehicle get back to a stock height with the added weight of a trailer. Let's take a look at that now. I've gone ahead and removed the weight distribution and disconnected it from the trailer.

Let's go ahead and get a stock measurement of our tow vehicle. Here at the rear, we've got about 39-1/2 inches to the underside of the wheel well. At the front, I've got about 38-1/2 inches. Now you want to be sure and record these measurements because these are the measurements we want to try and get back to when we engage our weight distribution system. Now I've gone ahead and hooked my trailer back up to my tow vehicle without weight distribution. Now let's take a look and see what the tow vehicle looks like. Here in the back I'm squatting about an inch, and here in the front, my vehicle is tilted upward about three-quarters of an inch.

Weight distribution should correct that. Let's hook it up. Now I've got my trailer hooked back up and my weight distribution engaged. Let's go ahead and take another measurement on our tow vehicle. Here in the back, we're back to stock height and same with the front. Excellent. Not using a weight distribution system can cause issues with your traction, tire wear, and handling.

Getting your vehicle back to stock with a weight distribution system can help prevent those problems. Now let's show you how it's installed. The first thing to note about using a weight distribution system is you need to make sure your trailer or camper is fully loaded and ready to go. This ensures proper weight is being applied to your tow vehicle. The shank can be installed in either the rise or drop position. The head is adjustable along the shank. You just need to make sure that the top of the ball is level with the top of the coupler when your trailer is level. The kit includes eight washers to adjust the tilt of your head. You don't have to use all eight. You just need to make sure to use enough to get your vehicle back close to stock. Our spring-bars fit inside the weight distribution head and are lifted on the L-bracket with the included tool. We can then place in our snap L-pin to help keep the spring-bar in place. This is where that steel-on-steel friction takes place, helping us with our sway control. Finally, our link plates are installed on our trailer's A-frame with the L-brackets on the outside. You just want to make sure and avoid your battery box or your propane tanks. Those may have to be relocated. It needs to be positioned between 27 and 32 inches from the center of your coupler. If you've used all eight washers for your head tilt and your vehicle still isn't back to stock, you can adjust your L-brackets. That's going to complete our look at the Equal-i-zer weight distribution system with a 4-point sway control and an included adjustable weight distribution chain. It has a 10,000 pound gross trailer weight and a 1,000 pound tongue weight, Part Number EQ37100ET.

Hi. i would like to know what would be recommended for a 2014 Jeep Chereokee 2wd for carrying a 36'6" trailer, hitch weight of 837, 6390lbs of dry/unloaded weight and 7837 of gross vehicle weight.

I'd be more than happy to help you choose an appropriate weight distribution setup, but according to the online owner's manual you can only tow up to a 2,000 lb trailer without the tow package and then up to a 4,500 lb trailer if you have the tow package on your 2014 Jeep Cherokee. That means that just the dry weight of your trailer alone is almost 2,000 lbs heavier than what your vehicle can handle if you have the tow package. You either need to use a different vehicle for towing or you need a smaller trailer if you'll be using your Cherokee to accomplish this.
