These receiver hitches have more towing capacity, use your standard truck tow bar, and offer easier trailer hookup than a standard ball hitch.  We use thick 1/4" plate steel for the backbone of these hitches then powdercoat them black for an extremely durable finish.  Installation is easy, they use existing bolt locations so there is no drilling or modifying your machine.  All mounting hardware is included.  Fits all 2007-10 Grizzly 700's and the new 2009-10 Grizzly 550.  Made in the USA!
