Draw-Tite has designed custom-fit trailer hitches since 1946 and is one of North America's most widely fitted hitch brands. Receiver hitches use solid all-welded construction and low-profile designs that follow modern vehicle contours, install with minimal bumper cutting or drilling, meet or exceed V5 CSA and SAE J684 standards, and carry a limited lifetime warranty.
Draw-Tite has been leading custom-fit trailer hitch design and engineering since its founding in 1946, and it remains one of the most widely fitted hitch brands in North America. The company's stated approach is straightforward: every hitch is tested rigorously so that it performs well beyond published industry standards, a philosophy it markets as Tested Tough. It sits within the Horizon Global towing group alongside Reese, Fulton, Bulldog, Tekonsha, Bargman and Wesbar.
Custom fit is the defining characteristic. Rather than adapting a universal design, Draw-Tite engineers a trailer hitch for a specific make, model and model year, so it bolts to existing frame locations with minimal bumper cutting or drilling. Low-profile designs follow the rear contours and aerodynamic styling of modern vehicles, which matters more than it once did now that rear fascias are shaped and sensor-equipped. Construction is solid all-welded steel for maximum strength, and every hitch meets or exceeds V5 CSA and SAE J684 standards and is backed by a nationwide limited lifetime warranty.
The range spans receiver sizes and classes to suit different loads, from 1-1/4 inch receivers for bike racks, cargo carriers and light trailers up through 2 inch receivers for heavier towing. Front mount hitches add a receiver at the front of the vehicle for winch mounts, snow plows, spare carriers and precise trailer positioning.
The Hidden Hitch series takes concealment further by mounting behind the vehicle's rear fascia, so the vehicle keeps its factory appearance until a removable receiver is fitted. Each is custom designed per make and model for a no-drill installation that does not compromise ground clearance, rated for up to 3,500 pounds gross trailer weight and 350 pounds tongue weight. Matching plug-and-play wiring completes the towing system.

Do not exceed the lower of the towing vehicle manufacturer's rating or these hitch limits.
