The TowSmart Hitch Ball is a key component to create a secure connection between your vehicle and trailer when towing your valuable assets. The heavy-duty construction is extremely durable with a chrome plated finish that is corrosion resistant. The hitch ball provides wrench flats for easy positioning in the X-Mount lockrail system. The lockrail functions as a built-in wrench preventing hitch ball rotation during installation or removal. The wrench flat design is universal to be used with any standard ball mount. It is important to know the total weight of the trailer (GTW) you are towing and the maximum towing capacity determined by the vehicle manufacturer.Specs: Class I, 1 7/8" Hitch Ball x 1" Shank Diameter x 2" Shank Length, 2000 lbs capacity
