How to Install a Equal-i-zer Weight Distribution System


Today, were gonna install the Equal-i-zer Sway Control Hitch part number EQ90-00-1200.First thing Im gonna do for our install is go ahead and attach your hitch bolt to the head assembly. And check your instructions for your shank distance. Were gonna install our hitch ball, lock washer and nut, go ahead and tighten it down. To install the hitch ball, what you gotta do is actually take the sockets where our spring bars go into and spread them apart. That way, you can get your socket inside. If you dont do that, its gonna be impossible to get the socket in there.

Then Ill go ahead and snug the bolt down and torque it down as specified in the instructions.Well go ahead and install the shank into our receiver hitch and install the hitch pin. Alright, next thing you wanna do is go ahead and go to your trailer and make sure its on level ground. I have the trailer sitting in level as best as possible and we wanna measure from the top of the coupler down to the ground. So its like 20 inches. So, when we set our head assembly onto our shank, we wanna measure that as close as possible.Ok, and before we install our head assembly, we need to place this washer assembly right here in that hole and that controls the tilt of the head.

Now, depending on the vehicle youre working with, it depends on how many washers youre using. More washers will tilt back the ball toward the trailer. Less washers will bring the ball close to the tow pin. Were gonna start off with five and try our initial judgment from there and see how it works.If were sure of our measurement, well go ahead and install the rest of our hardware. Use flat washers, lock washers and nut.

Alright, well go ahead and tilt our assembly up and theres a screw on the bottom that we need to adjust to take up the slack right here.Alright, well go ahead and turn our attention to the trailer. Once again, well install our frame brackets. We have one installed already right here. To give you a reference, the measurement were gonna use is from the center of the hitch ball is gonna be 32 inches to the center of our bracket. Now, if you have objects on your ton of the trailer that covers up that spot, you can move it in and out as needed and see the instructions for that distance.Our bracket consists three pieces of hardware.

Our first bracket with the short oval on one side is gonna get two of the short hex bolts just like that. Were gonna take our long bolt, well flip it over and put our long bolt through here, set that on the trailer, lock washer and nut. And then back to the other side and put our bolt as close as possible to the bottom of the frame. Were gonna take our bracket and for our initial setup, were gonna put it right in the middle. We may have to adjust it up or down. Well just try it out first and well install our two nylon lock nuts.Once were sure of our placement of our bracket, these two bolts here, were gonna tighten down and torque down as specified in the instructions.Alright, well go ahead and install our spring bar with the sticker facing out. This cutout will hit the bolt on the inside here. Well slide it into place then our pin then our clip. Were done with the driver side, lets go ahead to the passenger side and repeat the same process.With our spring bars installed, lets go ahead and back the truck onto the trailer and connect up. Okay, now what well do is go ahead and lock the coupler up to the ball and well go ahead and pick up the truck and trailer with the jack so it makes it easier to install the spring bar to the frame brackets.Alright, now were gonna take our spring bars and slide them onto the top part of our frame bracket. And put a pin that helps retain it in place and a clip on the bottom. With driver side down, well do the same thing on the passenger side. Go ahead and double-check our dimensions. From the center of our pin here to the outside edge, the absolute minimum should be three inches and were at 3 . Looks like were in good shape, lets go ahead and lower our truck and trailer and see how it sits.Alright, lets start our initial setup. Well go ahead and raise the truck and trailer once more to take the tension off the spring bars, get them out of the way and well adjust the frame brackets. Since we raised it up, we kinda lost some room to the side of the bar end but the kit does come with a tool that help you do that. You just need to last it a little bit over just like so.Alright, our driver side is done, repeat the same process over the passenger side. Alright, well go ahead and lower it one more time and check out our measurements with our truck and trailer.To increase our force to pick up our tongue load, we can go ahead and add one more washer to the head assembly and tilt it back more, try it again. If that doesnt work, well go ahead and raise our bracket one more hole up.Once were satisfied with our adjustment, well go ahead and torque down the last of our bolts.And thatll finish our install for part number EQ900-00-1200.

so if you angle the hitch toward the trailer is that creating more or less wd across the entire truck? I have a 36 ft trailer 912 tongue weight. setting up this trailer to tow where the vehicle is not squatting.. Truck is a 2017 titan. the hitch is husky round bar wd hitch.. so should I set the head height 3 inches higher then coupler? Pitch the head back ? trying to correct the sag

Yes tilting head of the weight distribution system towards the trailer transfers the most weight to the front axle of your truck. If the sag on your truck is only when the trailer is connected then using a weight distribution system is a great option. If your Titan sags without a trailer connected then you should consider additional suspension support for truck. Since you stated your tongue weight of your towing set up is at 912 pounds I hope you are using the Husky center line weight distribution system that is rated for 800-1,200 pounds, for us that is part # HT32218 and I have attached the installation instructions for your reference. I would start buy taking the measurements listed in the installation instructions, not just starting with 3 inches higher than the coupler and have the head angled back. The installation instructions provided a step by step process to get your weight distribution system set up and optimized. You will start by getting baseline measurements for the truck and trailer, then a rough height using the correct mounting location on the shank, then the angle of the weight distribution head is a fine adjustment for an optimized weight distribution system.

What happens adjustment wise if the trailer is on fairrly flat ground but the truck is starting on an incline ground?

The initial set-up and adjustments should be made when both the trailer and the truck are on level ground. Then the tongue weight of the trailer transferred to the truck's front tires. I have included a link to a similar weight distribution system and the installation instructions for your reference.
