Dedicated to making all their towing components in the USA, Curt Manufacturing is a company that focuses on the customer’s wants and needs, which explains the highly practical features of their 1999-2017 exterior parts for the GMC Sierra. Located in the cool green landscape of Wisconsin, Curt makes its components from heavy-duty materials such as top grade steel. The steel parts are not only black carbide powder-coated for rust resistance, but further rust-proofed by co-curing them in liquid Bonderite, a highly oxidation reducing compound. Their 1999-2017 hitches & towing line covers a huge range of options, so that you’ll never be at a loss for a strong, reliable hitch to support your latest towing task – from simple trailer balls to Level III, IV, and V trailer hitches, 5th wheel brackets, over-bed gooseneck installation brackets, and more. Curt’s confident enough in the durability of their products to cover them with a limited lifetime warranty.
