The Equal-i-zer hitch's Integrated 4-Point Sway Control™ keeps you safer on the road by resisting and reducing trailer sway caused by heavy winds, semi trucks, or a quick maneuver.

What is trailer sway?

Many things can cause a trailer to sway, but what exactly is trailer sway? Ideally, the trailer will follow directly behind the tow vehicle while traveling down the highway, but when the trailer is improperly loaded, the road surface is uneven, or when the wind picks up, the balance of the trailer can be offset - causing it to move from side to side. This side-to-side movement is called trailer sway. Trailers are particularly susceptible to trailer sway because they have high, long, flat sides on a light-weight frame. One major cause of trailer sway in the wind pushed from an oncoming semi on a two-lane highway.

How does the Equal-i-zer hitch prevent trailer sway?

You can enjoy a safer drive by towing with the Equal-i-zer hitch's Integrated 4-Point Sway Control system. Four unique friction areas are built right into every Equal-i-zer hitch. Steel-on-steel friction acts to continually resist a trailer's attempts to sway. This friction is the same that is used by locomotives to pull thousands of pounds of rail cars. Equal-i-zer hitch engineers have measured up to three times more resistance to lateral trailer movement with the Equal-i-zer hitch over other hitch options.


How do the 4 points of sway control work?

Sway Control Points 1 & 2: The patented Equal-i-zer hitch head provides two powerful points of rotational friction to resist trailer sway before it starts. The sway control is activated by downward pressure from the trailer tongue and upward pressure on the spring arms. The spring arms link the rotational sway control to the sway control brackets and distribute the trailer tongue weight. The rigidity of the sway control brackets allows the rotational friction sway control to safely and effectively hold the trailer in line behind the tow vehicle and combat sway.

Sway Control Points 3 & 4: The rigid brackets serve two purposes. First, they work in conjunction with the rotational friction sway control to reduce trailer sway. Second, the forward and back friction of the hitch arm on the bracket serves as a secondary sway control system. The sway control brackets work much like tow "add-on" sway bars, but with more sway-stopping pressure and less hassle. The sway control brackets are the innovative link that makes the Equal-i-zer hitch Integrated 4-Point Sway Control system so effective.
