Complete 2-piece bundle kit containing all necessary components for your project. Professional-grade components designed for reliable performance and long-lasting durability.
If you own multiple trailers or frequently tow a variety of loads, you know how much time and money are spent tailoring your towing system to each and every individual trailer. There is nothing more inconvenient than switching back and forth between a few different ball mounts and trying to remember which mount fits with which trailer. A CURT adjustable ball mount is your multipurpose towing solution. This CURT adjustable ball mount has a shank size of 2" x 2" and features three different trailer ball sizes to accommodate all standard coupler sizes: 1-7/8", 2" and 2-5/16". The 1-7/8" trailer ball offers a gross trailer weight capacity of 6,000 lbs. and a tongue weight capacity of 600 lbs. The 2" trailer ball has a GTW capacity of 7,500 lbs. and a TW capacity of 750 lbs., and the 2-5/16" ball offers 10,000 lbs. GTW and 1,000 lbs. TW. This allows you to easily tow a variety of trailers and to ensure that each one tows smoothly and securely. This tri-ball ball mount also features an adjustable shank assembly with multiple mounting holes for varying ball heights. Each trailer ball can be raised to a maximum of 5-3/4" rise or lowered to a maximum of 5-3/4" drop, allowing you to make your trailer completely level in any towing situation. It includes three 5/8" hitch pins for quick and secure installation, and the adjustable shank can also be used with our multipurpose ball mount attachment #45008 for even more versatility. All CURT adjustable ball mounts are made with sturdy steel construction and come with a durable powder coat finish for long-lasting rust, scratch and UV resistance.

Make your tow vehicle and trailer more secure by keeping them locked up tight with a CURT hitch lock. Like a hitch pin and clip, a hitch lock is designed to insert into the fastener hole in the side of a receiver tube in order to hold a ball mount or hitch-mounted accessory in place. While a CURT hitch pin does offer sufficient strength for keeping your ball mount firmly attached, a CURT hitch lock goes one step further. CURT hitch locks allow you to lock your ball mount into your trailer hitch, deterring theft and preventing anyone from detaching your trailer at the ball mount and towing away your property without your permission. This CURT hitch lock features a barbell design and comes with a 5/8" pin diameter to fit a 2", 2-1/2" or 3" receiver tube size. CURT barbell hitch locks are comprised of a pin with two end caps and a round locking mechanism. They are key-operated and activate with a simple 1/4-turn. They also come with watertight dust caps to keep out the elements and prevent corrosion. For the ultimate in towing security, a hitch lock and coupler lock used together will provide security at both the vehicle-side and trailer-side of your towing setup. For your boat, ATV or camper, keep your toys more secure with CURT hitch locks.

(2) Secure the receiver tube assembly to the shank assembly using two 5/8" hitch pins and clips. (3) Tighten the anti-rattle bolt to eliminate movement between the shank and receiver tube assemblies. (4) Insert the ball mount weldment with the required ball size pointing upward into the receiver tube assembly and secure with a hitch pin and clip.
