When you mount a ball-mount on your trailer hitch, you expect it to stay put. Whatever type of load you are hauling, having towing equipment that can work as hard as you do is a must. For all-types of heavy-duty towing, CURT 5/8 in hitch pins and clips pack a little extra punch. We make our 5/8 in hitch pins out of solid steel and coat them in one of four finish options. All of these finishes offer excellent resistance to rust and corrosion for long-lasting, smooth operation. CURT hitch pins are also constructed with a 105 deg bend, creating a useful handle for a better grip and allowing the pin to stay securely engaged in the trailer hitch and ball mount. This particular 5/8 in hitch pin features a zinc finish and comes with a standard retainer hole to accept the included clip. It provides reliable installation for any ball mount or hitch-mounted accessory with a 2 in shank, making it the ideal fit for Class 3, 4 and 5 trailer hitches.
