CURT Class 4 Trailer Hitches
Built for serious towing, a class 4 trailer hitch can handle almost any non-commercial job, including large boat trailers, utility trailers and full-size campers. A class 4 hitch can also be used with a weight distribution system for added stability and strength.
When an especially bulky trailer or heavy load requires more towing power, the class 4 steps in to take the reins. CURT class 4 trailer hitches are made with quality all-American steel and get their strong designs from the ingenuity of our talented engineers. They are precisely planned, carefully welded and scrupulously tested to ensure performance at the utmost level. Class 4 boasts a gross trailer weight capacity of up to 10,000 lbs. and a tongue weight capacity at 1,000 lbs. Also, like class 3 hitches, class 4s can be used in combination with a weight distribution hitch to increase the overall towing capacity. With a weight distribution system attached, the gross trailer weight capacity increases up to 14,000 lbs. and the tongue weight capacity increases to 1,400 lbs. This makes the class 4 hitch a prime candidate for towing large boat trailers, RVs, livestock trailers and other similarly large trailers. The class 4 trailer hitch is commonly found on such vehicles as mid to full-size pickup trucks and SUVs. Class 4 hitches accept ball mounts and other hitch-mounted accessories with a 2" x 2" shank.
Like all CURT trailer hitches, our class 4 line goes through a strenuous finishing process, receiving a shot blast and wash to create a flawlessly smooth surface, and then being co-cured with two finishing coats. A liquid A-coat ensures that the hitch stays well protected against rust, chipping and UV damage, and the final powder coat gives it a sleek look in gloss black, also protecting against scratching and marring. This co-cured finish is backed by a one-year warranty, while the hitch as a whole comes with a limited lifetime warranty.
