This CURT class 2 trailer hitch with ball mount is made for light-duty towing, having a gross trailer weight capacity up to 2,500 lbs. and a tongue weight capacity of 250 lbs. This makes it an excellent choice for most smaller size trailers such as single-axle utility trailers, small boat trailers, popup campers and some recreational vehicle trailers. It is also perfect for adding cargo space with a hitch-mounted cargo carrier or bike rack (NOTE: Never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc).CURT class 2 trailer hitches are generally used on full-size cars, crossover SUVs, compact SUVs, minivans and even some smaller pickup trucks. This particular hitch and ball mount combination is designed to be a custom-fit trailer hitch for certain years of the Infiniti Q45 sedan (to verify your vehicle compatibility, see the CURT application guide at curtmfg.com). It features a square tube frame and comes with a hitch pin and clip and all hardware necessary for a complete installation. This class 2 hitch kit also comes with a Euro Mount ball mount, with a 2" diameter ball, to be a complete towing package. CURT class 2 hitches are made with innovative engineering that takes shape in quality materials. Our engineers work with real vehicles and advanced programs to design each hitch to succeed. CURT trailer hitches are constructed with American steel by state-of-the-art machinery and our skilled fabricators, welders and technicians. We coat each hitch in a liquid Bonderite coating that provides long-lasting corrosion, chip and UV resistance, and then finish them in a high-gloss black powder coat. Our quality processes and construction give us the confidence to include a limited lifetime warranty and a one-year finish warranty on all of our class 2 hitches.
