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 found on full-size cars, crossover SUVs, minivans and mid-size trucks. That is because the class 3 packs the punch of a heavyweight hitch while still staying light on its feet. This CURT class 3 hitch offers a gross trailer weight capacity of 3,500 lbs. and a comparable tongue weight capacity of 525 lbs. It is designed to be a custom-fit trailer hitch for certain years of the Toyota Rav4 (to verify your vehicle compatibility, see the CURT application guide at curtmfg.com). It features a round tube frame and comes with all necessary hardware for a complete installation.The 2" x 2" receiver tube opening of this class 3 hitch is able to accept a hitch-mounted accessory, such as a bike rack or cargo carrier, or a ball mount to tow most standard size trailers, including utility trailers, single-horse livestock trailers, boat trailers and large campers. 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, this class 3's gross trailer weight capacity increases to 4,000 lbs. and the tongue weight capacity to 525 lbs. (NOTE: Never exceed the lowest weight capacity of any towing component).CURT class 3 trailer hitches are engineered to be strong and capable, having a quality steel frame and a solid finish. They are put through strenuous testing before being deemed ready for market and come with two coatings — a liquid Bonderite 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 one-year finish warranty.
