Ask around any campground and someone will point at the hitch on their truck and tell you to get an Equal-i-zer. It has been voted the Gold Trailer Life Readers’ Choice Award winner for more than a decade straight, and over 99% of owners say they’d recommend it. Here’s what’s actually behind that reputation, and how to tell if it’s the right hitch for your rig.

What a Weight Distribution Hitch Actually Fixes

Every trailer pushes down on your hitch ball. That downward force, called tongue weight, should be 10% to 15% of your loaded trailer weight. An 8,000 lb camper puts 800 to 1,200 lbs on the back of your truck.

On a standard ball mount, that load acts like a teeter-totter over your rear axle: the back squats, the front lifts, and you lose steering grip and braking power right when you need them. A weight distribution hitch uses spring bars to lever part of that load forward to your front axle and back to the trailer axles, so the truck sits level and steers like it should. The math is laid out in Gross Trailer Weight vs. Tongue Weight.

How 4-Point Sway Control Works

Most weight distribution hitches handle the load and leave sway to a bolt-on friction bar. The Equal-i-zer builds sway control into the hitch itself, using steel-on-steel friction at four points:

• Points 1 & 2 (hitch head): The patented head clamps down on the two spring bar sockets, creating rotational friction that resists the trailer swinging side to side.
• Points 3 & 4 (L-brackets): The spring bars ride on rigid brackets bolted to the trailer frame. Tension on the bars creates friction that holds the trailer in line.

Your tongue weight is what powers it. The heavier the load pressing down, the harder those four points grip. Equal-i-zer’s engineers measured up to three times more resistance to lateral movement than other hitch options (full breakdown here).

Because there’s no add-on sway bar, there’s nothing to disconnect before backing into a campsite, making a tight turn at the pump, or driving in rain. When the spring bars are up, sway control is on.

Built in the USA, Backed for Life

The Equal-i-zer Hitch is engineered and manufactured in the USA from forged American steel, and it’s the only sway control hitch that’s 100% American made. Every hitch comes with a limited lifetime warranty.

Picking the Right Size

Match the hitch to your loaded trailer, not the brochure weight. Water, propane, and gear add up fast.

Model	Max Tongue Weight	Max Gross Trailer Weight
90-00-0400	400 lbs	4,000 lbs
90-00-0600	600 lbs	6,000 lbs
90-00-1000	1,000 lbs	10,000 lbs
90-00-1200	1,200 lbs	12,000 lbs
90-00-1400	1,400 lbs	14,000 lbs
90-00-1600	1,600 lbs	16,000 lbs

Not sure where you land? Use the hitch size calculator and the shank size calculator. A few details worth knowing:

• Every model except the 4,000 lb version ships with a 2-5/16″ ball pre-installed and torqued. The 400/4,000 needs a hitch ball added.
• A standard 2″ shank is included. Lifted trucks and 2-1/2″ receivers need a different shank.
• Standard brackets fit trailer frames up to 6″ and bolt on without drilling. Brackets are also available for 4-3/8″, 8″, and 10″ frames.
