CURT MANUFACTURING, LLC. part description

When an especially bulky trailer or heavy load requires more towing power, class 4 steps in to take the reins. CURT class 4 trailer hitches are made with all-American steel and a powerful design. They are commonly found on commercial vans and larger pickup trucks and SUVs. This particular class 4 trailer hitch boasts a gross trailer weight capacity of up to 10,000 lbs. and a tongue weight capacity of 1,000 lbs., giving it the raw towing power needed to tow most campers, boat trailers, car haulers and large utility trailers, as well as a winch mount or cargo carrier. It is designed specifically to be a custom-fit trailer hitch for certain years of the Chevrolet Silverado 1500 or GMC Sierra 1500 (to verify your vehicle compatibility, see the CURT application guide at curtmfg.com).This class 4 features a square tube frame and comes with all necessary hardware for a complete installation on your vehicle. Also, like many class 3 hitches, this class 4 hitch can be used in combination with a weight distribution hitch to increase its overall towing capacity. With a weight distribution system attached, the gross trailer weight capacity increases up to 12,000 lbs. and the tongue weight capacity up to 1,200 lbs. (NOTE: Never exceed the lowest weight capacity of any towing component).Class 4 hitches can accept any ball mount or hitch-mounted accessory 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 Bonderite coating and gloss black powder coat finish ensure that the hitch stays well protected against rust, chipping and UV damage. This co-cured finish is backed by a one-year warranty, while the hitch as a whole comes with a limited lifetime warranty.
