When we came to the limit of trailer hitch towing capacity, we wanted to know what else was out there. What could we discover off the beaten path? So we kept going. CURT Xtra Duty hitches begin a class of their own, beyond class 4 and beyond anything the standards dictate. Xtra Duty trailer hitches have a gross trailer weight capacity up to 17,000 lbs. and a tongue weight up to 2,550 lbs. These hitches are not for the faint of heart. A class 5 trailer hitch is designed for the hard road where only 3/4-ton and 1-ton pickup trucks and SUVs dare to tread. They are capable of pulling almost any heavy-duty trailer, including livestock trailers, RVs, large boat trailers, double-axle utility trailers and toy haulers. The Xtra Duty hitches feature a 2" x 2" receiver tube opening and can be used with a weight distribution system for more stability, though the GTW capacity remains at 17,000 lbs.
In our drive to create a more powerful hitch, CURT has not neglected the finer details. CURT Xtra Duty class 5 trailer hitches are welded with precision and go through multiple cleaning stages to create a smooth surface that is ready to accept our co-curing finish. To protect these hitches from corrosion and chipping, they are coated first in a liquid Bonderite® coating and then finished in a high-quality black carbide powder coat. They also come with grade 8 mounting hardware for solid installation and are backed with a one-year finish warranty and overall limited lifetime warranty.
