In the world of commercial towing, more is expected. A job cannot be completed if the equipment cannot handle the workload. That is why CURT developed the Commercial Duty and Commercial Duty+ Class 5 trailer hitches, the ultimate in rear mount hitches. Constructed from steel and engineered for power, these Class 5 behemoths come with a gross trailer weight rating that ranges from 18,000 lbs. to an unprecedented 20,000 lbs., and both share a tongue weight capacity to match, rating in at 2,700 lbs. This extra high tongue weight capacity allows these Class 5 trailer hitches to be able to bear the added load of heavyweight commercial trailers. Also, Class 5 hitches feature a wide 2.5 in. x 2.5 in. receiver tube opening to accept only the largest, most capable ball mounts such as forged and welded designs. CURT’s Commercial Duty and Commercial Duty+ is a match for towing virtually any heavy-duty coupler-style trailer. They are designed for mounting on commercial trucks and other heavy-duty pickup trucks, including diesels and flatbeds. CURT’s CD and CD+ hitches are guarded by a co-curing of liquid A-coat and black carbide powder coat finish and come backed with a 1-year finish warranty. If that was not enough, they also mount with grade 8 hardware, included with each hitch, and feature a limited lifetime warranty to give you the confidence to tackle every job head-on.
