The Blue Ox SwayPro uses a built-in sway control system that keeps your trailer centered and steady as you tow. The hitch head has a positive caster angle that works with the trunnion-style spring bars to create a self-centering force, keeping your trailer in line even when crosswinds or passing trucks try to push it off course. The constant tension in the trunnions and tight chain design limit movement without the noise and resistance of traditional friction-style setups. You’ll get smoother, quieter towing and more control on every trip.

With a gross towing weight of 3,500 lbs and a tongue weight range of 150 lbs to 350 lbs, this system is built to evenly distribute your trailer’s load across all axles. That means no more rear-end sag or light steering feel. The result is better braking, improved balance, and a level setup that restores your vehicle’s full control and stability while towing.
Getting the SwayPro ready is simple. The hitch head comes with the correct angle pre-set, so there’s no need for complicated adjustments. The rotating lift brackets make connecting the chains quick and easy — just insert the lift chain into the slot and rotate the bracket with the included wrench until it locks in place. The trunnion bars slide and pin into position with no tools required, and the clamp-on brackets mount without drilling. You’ll have it installed and dialed in within an hour or two.

Unlike friction-style sway systems that need to be disconnected before reversing, the SwayPro lets you back up just as you normally would. The self-centering design and fixed tension work whether you’re pulling straight or maneuvering into a tight campsite. Plus, because the system’s sway control happens inside the head and chain brackets, it operates silently — no grinding, popping, or squealing.


The Blue Ox SwayPro is made from powder coated steel that resists corrosion and holds up to years of use. The head assembly includes grease zerks for clean and simple maintenance. The complete system includes the head assembly, adjustable shank, spring bars, lift chains, rotating lift brackets with handles, reducer bushing for the ball shank, pin and clip, hitch ball, and all necessary hardware. It fits 2" x 2" trailer hitch receivers rated for use with weight distribution systems and supports trailer frames up to 6" tall.

Very good. My toy hauler pulls perfect, especially after installing the 58 spacers between the trailer tongue and the clamp on lift brackets.

You will definitely want to grease the 2 grease zerks inside the head assembly often. As well as lubricate any moving part that is in the elements. For more rust prevention tips, see the attached help article:
