Curt Manufacturing 13-14 mercedes glk350 rwd/4matic class iii receiver hitch

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 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, including utility trailer, boat trailers, campers, single-horse livestock trailers and trailers designed to haul ATVs, personal watercraft, snowmobiles and other similar recreational vehicles. 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.
