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 passive sway control to deliver a smoother, safer ride. The TruTrack 2P features a unique spring bar attachment system. Like all WD hitches, it uses a pair of spring bars to leverage the trailer tongue weight and spread it across all axles of the vehicle-trailer combination. However, instead of using spring bar chains, the TruTrack connects to the trailer frame using heavy-duty, adjustable support brackets that hold the spring bars in place laterally and vertically. While regular spring bars angle from side to side, the integrated sway control arms resist this movement and keep the trailer better aligned. In addition to its integrated sway control, the CURT TruTrack offers the same great quality as our other WD hitches, making it the perfect choice for campers, livestock trailers and other heavy-duty trailers. We stand behind this uncompromising hitch, and to prove it, we back it up with a limited lifetime warranty.
