Ford has increased towing and payload capability for its 2017 Super Duty F-350, F-450, and F-550 chassis cabs with new frames and a next-generation 6.7L V-8 PowerStroke diesel with more horsepower and torque, Ford has announced at the Work Truck Show.
Ford's second-generation 6.7L V-8 diesel adds 30 horsepower and 90 lb.-ft. of torque for a maximum rating of 330 hp and 750 lb.-ft. — a high-water mark for the trucks.
The 2017 chassis cabs also get a new frame consisting of 95% high-strength steel and eight times more torsional rigidity than the previous frame with through-welded crossmembers and fully boxed rails under the cab and forward.
The improvement results in a 40,000-pound gross combined weight rating (GCWR) and a 500-pound increase in front gross axle weight rating to 7,500 pounds to support bigger snowplows, taller utility buckets and cranes, as well as larger ambulance bodies or other specialized vocational body upfits. Towing capacity also increases over the outgoing models.
