When heavy winds or passing trucks start pushing your trailer around, the Blue Ox SwayPro Weight Distribution w/ Sway Control for 2-1/2" Hitch-15K GTW, 1.5K TW keeps it locked in line. The hitch head has a built-in positive caster angle that constantly centers the trailer behind you, while the trunnion bars stay under tension to hold everything steady. Four points of sway control—two in the head and two at the brackets—work together quietly and smoothly to keep your trailer tracking straight without the grinding or popping common to friction systems.
Uneven weight can make steering light and braking unpredictable. The SwayPro evenly distributes up to 1,500 lbs of tongue weight and supports 15,000 lbs of gross towing weight so the load sits level across the axles. That balance reduces rear sag, evens out tire wear, and gives you a stable, predictable feel on any road. With a 2-5/16" hitch ball and top-mount trunnion-bar setup, it’s built to handle serious loads without drama.
A lot of weight distribution systems need to be unhooked before reversing, but the SwayPro doesn’t. Its rotating lift brackets keep the chains tight and secure, limiting bar movement while still allowing full-range backing. Since only a few chain links hang loose, everything stays snug and silent—no creaks, snaps, or groans when you turn or park.
Getting ready to tow shouldn’t take half the day. The SwayPro’s hitch head comes pre-set with the right angle, so you can bolt it up without fiddling with washers or thumb screws. The trunnion bars slide in and lock with a simple pin and clip, and the clamp-on rotating brackets need no drilling. Using the included wrench, just rotate to tension the chains and you’re ready to roll.
Durable powder-coated steel construction resists corrosion, and grease zerks in the head make upkeep clean and simple. With a 13" shank length, up to 10" rise, and 5" drop, it’s easy to dial in the perfect trailer height. All hardware, lift brackets, spring bars, and hitch ball come in the box—everything you need for a quiet, confidence-inspiring tow.
