Review of Equal-i-zer Weight Distribution EQ37100ET


Today we're gong to be taking a look at the Equal-i-zer Weight Distribution System with 4 Point Sway Control, this system is going to have tunnel weight rating of 600 pounds to 1,000 pounds and a maximum gross towing weight rate of 10,000 pounds. Now what this system does is it evenly distributes weight over the axles of your tow vehicle and your trailer which is going to offer better stability and better control. Ultimately a weight distribution system is going to create a more level ride for both the tow vehicle and the trailer. Now again, this one's going to have integrated 4 point sway control which is really going to help limit side to side movement of your trailer. We're going to have these brackets right here that are going to keep the spring bars in place for a rigid system that holds the trailer in line at all times. This unit does not use lift chains so that way the spring bars aren't able to move freely, they're going to be held in place and they're going to slide back and forth, which is going to create steel on steel friction. Down here we're going to have 2 points of sway control that are created by the steel on steel friction that occurs when the spring bars slide within these L-brackets that are mounted on the trailer tongue. The other 2 points of sway control are here at the head assembly, it's a really nice feature of the unit.

The downward pressure that is placed on the hitch ball by the trailer is combated by the upward pressure that is exerted by the spring bars that are mounted into these sockets right here. Those are going to be held in place with pins and clips, nice sturdy durable design there. The upward force that's placed on the spring bars on either side of the system creates the rotational friction that essentially forces your trailer in line at all times. With this system we're going to have direct friction that's applied to the spring bars. It's really going to help stop sway right away. No additional parts are needed, nothing that can be added on to increase it's all built in, it's integrated and it's going to provide an extremely durable functional sway control system.

That's a really nice design of the unit. Now the unique design of the unit makes this system compatible with surge type brake actuators. Another neat features of this system is that you can back your trailer up without having to remove or uninstall any components. These spring bars are going to flex appropriately over uneven terrain which is going to offer a really nice control to even ride without the bounce. It's also going to be very quiet. These brackets are no drill clamp on brackets that can be adjusted along your trailer frame to accommodate frame mounted accessories such as gas tanks, tool boxes or generators. Then when it comes to the head assembly the desired tilt is achieved by using a traditional washer design.

It's going to come with this spacer rivet and it's going to come with some washer right here so you can add or remove washers from the spacer rivet to tilt the head up or down. Underneath the head assembly there's going to be a slot right there for that spacer rivet to be installed. The unit's going to come with your detailed installation instructions and owners manual and it's going to help walk you through the appropriate tilt for your application. Then also underneath the head assembly or underneath the hitch ball there's going to be an angle set bolt, you'll need to tighten that down a little bit. That is included to make sure that the spacer rivet is in correct positioning when it comes to making sure you get the tilt you need for your application. The unit's made from a strong steel construction, it's dip steel.

It's going to very durable and corrosion resistant, it's got a really nice finish on it. It's going to last a long time and it's going to look great for a long time. Now the system's going to come with everything that you see here on the table, as well as the detailed installation instructions and owners manual that I mentioned earlier. It also comes with your 2-5/16 inch hitch bar rated for 10,000 pounds. It's got the lock washer underneath as well as the nut to get it fully installed. You will need to get that torque down to the specifications listed by the manufacturer. One of the things that I want to mention that will make that process easier is using a 1-7/8 inch thin walled socket. It is recommended for the hitch ball installation. We do carry that here at etrailer.com, it's sold separately you can find it with part number EQ70-00-4800. That's also going to come up, or excuse me it's going to come with this snap up lever. This is designed to ease installation by reducing the amount of lifting required by the trailer jack. When you're getting your arms in place on these brackets. You can see that the unique design of our brackets allow for the unit to fit a variety of trailer frame sizes. Again, the hitch ball on the unit is 2-5/16 of an inch. The adjustable shank is designed to go into a 2 inch by 2 inch trailer hitch receiver that's rated for use with the weight distribution system. The brackets are going to fit trailer frames with the height from 3 inches, that would be at the lowest setting right here all the way to 6 inches, so 3 inches, 4 inches, 5 inches and 6 inch tall trailer frames. I want to mention just the adjustable shank here. I don't have it fully installed just because I wanted to be able to take it out and show it to you. This is going to feature a 6 hole design, so that's the amount of adjustment holes that we right here on the upright bar of the shank. These holes are going to be separated on center by an inch and a quarter. The shank length, I took a measurement and I'll do it again for you, place it right here. We'll go over some measurements real quick with that. The overall length of the shank from very front to very back is going to be 12 inches. If we take a measurement from the center of the adjustment holes to the center of the hitch pin hole we're looking at 8 inches. From the front of the shank to the center of the hitch pin hole we're looking at a measurement of 9 inches. Then from the back of that upright bar to the center of the hitch pin hole we're looking at about 7 inches. Now if you're using this in the rise position you want to make sure you have enough clearance at the back of the vehicle with this support bar right here. It's a welded construction, nice solid steel design. I'm going to give you a measurement from the bottom of that base right there, that brace right here at the weld so at the base of the brace to the center of the hitch pin hole. We're looking at a clearance measurement of around 4 inches. Again, that's only going to come into play if you're using the adjustable shank in the rise position like this. Real quick just to go over the hardware that it comes with. Again, we talked about the snap up lever. It's going to come with this set right here. This is all to get the head assembly installed on that adjustable shank. Then you've got your spacer rivet with the washers and then you're also going to have a 5/8 inch diameter hitch pin and clip to get the adjustable shank installed in your trailer hitch. Now if you're using this in the rise position with the head assembly at the highest setting it's going to give you a maximum rise of 7 inches, that's measuring from the inside top edge of the receiver tube of your hitch or the top of the shank to the top of the ball platform. If you flip this over to the drop position and lower the head assembly at the lowest setting it's going to give you a maximum drop of 3 inches from the inside top edge of the receiver tube of your hitch to the top of the ball platform. These spring bars, again they're held in the head assembly with a pin and clip, very easy to get those installed as well as to remove them. These are going to measure 36 inches long and then they're going to give us a width measurement of 1 and 3/8 of an inch. They're a nice square design. The product is made right here in the USA and it's going to be covered with a limited lifetime warranty. That's going to do it for today's look at the Equal-I-zer Weight Distribution System with the 4 Point Sway Control.
