In agriculture, construction and even military applications, pintle hitches are the trusted product of specialized towing. They are notorious for their high weight capacity and simple design. The basic pintle hitch is essentially a hook and loop, with the hook attached to the vehicle and the loop mounted on the trailer. Because of their simple design, pintle hitches are able to have thicker metal construction and more secure coupling. CURT has a wide variety of pintle hitches and pintle-style products to give you a complete solution for your heavy-duty towing needs. This lunette eye uses a threaded shank and castle nut mounting system to install on a trailer tongue. It features a forged steel alloy construction and boasts a gross trailer weight capacity of 45,000 lbs. (NOTE: Never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). With a 3" inside diameter, this lunette ring fits a variety of CURT pintle hooks and ball and pintle combinations. The heavyweight towing done with pintle hitches implies a certain amount of wear and tear on your towing equipment, and to prepare for this, CURT uses a quality finish on all our pintle mounts, lunette eyes and combination pintle hitches. This lunette eye is coated in a tough black powder coat finish to provide the perfect amount of rust and scratch resistance needed to face the heavy-duty towing you do every day.
