The Curt TruTrack Trailer-Mounted Weight Distribution Hitch is easy to couple and doesn't require adjusting the spring bars after initial setup. Traditional weight distribution hitches require the spring bars to be connected and disconnected each time the trailer and tow vehicle are hitched or unhitched. This means the TruTrack can be quickly coupled and uncoupled without resetting the trunnion bars, making the coupling process a breeze. Simply set up the TruTrack and then couple or uncouple your trailer using the quick-connect hitch when you need to separate the trailer and tow vehicle. While many weight distribution hitches are made to be compatible with a sway control attachment, the Curt TruTrack is an advanced weight distribution system that integrates the sway control function into the hitch's design. It combines precise weight distribution with active sway control to deliver the smoothest, safest ride possible.•Patent-pending trailer-mounted design simplifies installation and decoupling•Prevents need to uninstall spring bars or remove hitch when disconnecting•Independent, two-part system eases lifting by keeping hitch weight on trailer•Brackets use friction to resist lateral movement and distribute weight evenly•Innovative horn cradles the trailer head, providing effortless coupling•Unique snap-up brackets mount spring bars with no extra tools needed to lift•Four points of sway control work together to keep trailer alignedSpecificationsReceiver Size: 2 Trailer Weight Capacity: 10, 000 Lbs.
