Equal-i-zer 4-Point Sway Control Hitch 4,000 lb Trailer Rating

In this review the Equal-i-zer 4-point sway control hitch is evaluated for drivers who tow bumper-pull trailers and want the strongest integrated sway resistance plus weight distribution in one package. The bottom line: this hitch is for owners of RVs, horse, cargo, boat, and utility trailers up to 4,000 lb gross trailer weight who value stable handling and even weight transfer across axles. The most compelling reason to buy is its integrated 4-point design that provides higher sway resistance than other standard hitches while also moving tongue weight to the tow vehicle and trailer axles.

Key Features

• Integrated 4-point sway control: Provides the highest level of resistance to trailer sway so the rig tracks straighter at highway speeds under typical conditions.
• Weight distribution design: Transfers tongue weight across all axles to improve steering and braking by keeping the tow vehicle's front end planted.
• Broad trailer compatibility: Engineered to work with virtually all bumper-pull trailers, including those with surge brakes, offering flexible use across trailer types.
• Clear capacity limits: Rated for a maximum gross towing weight of 4,000 lb and 400 lb tongue weight so buyers can match it to their trailer safely.
• Adjustable positioning: Sway control bracket positions between 27 in and 32 in back from the coupler center to fit common frame layouts.
• Durable hardware dimensions: Uses 36 in by 1 in spring bars and a 12 in shank to accommodate typical receiver heights and loads.

Who It's For

The Equal-i-zer is best for light- to mid-weight trailer owners who regularly tow RVs, boats, cargo, or horse trailers and want a single hitch that combines sway control and weight distribution. Owners who value a heavy-duty, engineered solution to reduce sway and improve handling on longer trips will appreciate the performance and build quality.

This hitch is not for users whose trailers exceed a 4,000 lb gross towing weight or who require an included ball, since the ball is not supplied. Those who need near-silent operation at high sustained speeds should note reports of some creaking under load and consider whether that limitation matters for their use.

Pros & Cons

Pros

• Very effective at eliminating trailer sway thanks to its unique 4-point design.
• Improves steering and braking by distributing tongue weight across axles.
• Sturdy, heavy-duty construction that users report holds up well on long drives.

Cons

• Ball is not included, so buyers must purchase a separate 2-5/16 in ball to tow immediately.
• Some users report creaking or noise during operation, particularly at higher speeds.
