The Curt TruTrack Weight Distribution Hitch combines precise weight distributing with active sway control to deliver the smoothest, safest ride possible. This, coupled with the easiest setup in the industry, truly makes the TruTrack unparalleled in its class. The TruTrac 4P 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 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.•Integrated sway control actively resists sway and levels the vehicle and trailer•Uses spring & cam system with hardened components, instead of friction alone•2" shank can be flipped to provide necessary drop or rise•Tilt adjustment feature simplifies setup and installation•Carbide black powder coat, black-oxide-plated cams and stainless steel balls•Fits virtually all A-frame trailersSpecificationsReceiver Size: 2 Trailer Weight Capacity: 15, 000 Lbs.
