Trailer sway on the highway or in windy conditions can turn a trip into a white-knuckle drive. The Blue Ox SwayPro Weight Distribution System keeps everything steady with four points of built-in sway control. The trunnions in the head assembly hold the spring bars under constant tension, automatically forcing the trailer in line, while the rotating lift brackets keep the chains tight and stable. The result is smooth, predictable tracking even when passing semis or towing in crosswinds—no extra sway bar needed, and you can still back up without disconnecting.

Uneven weight transfer can cause sagging, poor handling, and uneven braking. This system distributes the load evenly over all axles, creating a more level and stable ride. It’s rated for 15,000 lbs gross towing weight and 1,000 to 1,500 lbs tongue weight, so it’s built to handle substantial trailers. The trunnion-style spring bars flex under load for a controlled ride that stays comfortable mile after mile.
Some weight distribution systems make you fight with complicated head angle adjustments or stiff lift brackets. The SwayPro simplifies the process. The required tilt is already built into the head assembly—no washers, no fine-tuning. Just move the head to the right height on the shank and tighten it down. The rotating-latch lift brackets work with a simple wrench turn to secure the chains, locking automatically with a push pin. It’s fast, clean, and easy to set up every time.

The SwayPro’s self-locking trunnion bars snap securely into place and remove with a quick lift of the locking pins—no loose clips or greasy parts to wrestle with. The clamp-on brackets attach directly to 3"–6" trailer frames and require no drilling, keeping your setup simple and your trailer intact. With a shank that fits 2" hitches and offers up to 13" rise or 7" drop, it’s ready to dial in the perfect towing height. Powder-coated steel construction and two grease zerks in the head assembly make it durable, quiet, and easy to maintain for years of towing.

The clamps on this WDS system part # BXW1506 may not install properly on a c-channel trailer frame. c-channel frames will need the bolt on bracket option part number: BXW4021.
