While many weight distribution hitches are made to be compatible with a sway control attachment, the CURT TruTrack is an advanced WD system that integrates the sway control function into the design of the hitch. It combines precise weight distributing with integrated sway control to deliver the smoothest, safest ride possible. Setting up the TruTrack WD hitch is faster and easier. While other WDs use washers and blind guesswork to find the proper tilt, the TruTrack employs interlocking nuts and six preset holes to provide specific angles of tilt and a simpler adjustment method. Unlike most WD hitches that require you to partially disassemble the hitch head to make adjustments, the interlocking nuts can easily be accessed on the outside of the head, making installation fast and adjustment easy. This replacement TruTrack weight distribution head is made from heavy-duty, cast steel for reliable strength and comes with a durable powder coat finish to resist rust and wear.
