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. This replacement hardware kit for the TruTrack 2P weight distribution hitch includes the necessary hardware for attaching the weight distribution head, the adjustable shank and the spring bars. It includes nuts, bolts, safety pins and a pin & clip.
