The CURT Class 3 trailer hitch is the most common type of trailer hitch installed on full-size pickup trucks and SUVs. It is also popular on crossovers and mid-size trucks. That is because the Class 3-packs the punch of a heavyweight hitch while still staying light on its feet. CURT Class 3 hitches range in gross trailer weight capacity from 3,500 lbs. to an impressive 8,000 lbs. and offer a comparable tongue weight capacity ranging from 350 lbs. to 800 lbs. These hitches are engineered to be strong and capable, having a quality steel frame in round tube or square tube form. Class 3 trailer hitches are able to tow most standard size trailers. This type of hitch uses a 2 in. x 2 in. receiver tube opening to accept a ball mount or towing accessory with an equivalent shank. One special feature about the Class 3 that is not found in Classes 1 or 2 is its compatibility with a weight distribution hitch. When used in combination with a WD hitch, the Class 3 hitches gross trailer weight capacity increases to 12,000 lbs. and the tongue weight capacity to 1,200 lbs. CURT Class 3 hitches are put through strenuous testing before they are deemed ready for market. They also come with 2 coatings a liquid Aquence coating and a powder coat in high-gloss black that cure together to form a strong resistance against rust, scratching, UV damage and other wear. Our hitches are our pride, and as such, we back them up with a limited lifetime warranty and a 1-year finish warranty.
