Curt Manufacturing Class iii/iv towing starter kit(includes 4in drop ball mount+2in chrome ball+locking receiver pin)

This CURT towing starter kit features a Fusion ball mount #45154 with a 2 x 2 shank to fit a class 3, 4 or 5 trailer hitch. Much like CURT Euro Mount ball mounts, Fusion ball mount trailer balls require no torqueing and can never be loosened or stolen. The Fusion ball mount in this towing starter kit features a 2 diameter trailer ball, a 4 drop and an 8-1/8 length. It offers a gross trailer weight capacity up to 7,500 lbs. and a tongue weight rating of 750 lbs. Also included in this towing starter kit is a CURT hitch lock #23021. The lock is a dead bolt-style lock and provides an extra level of security when mounting the Fusion ball mount. Much like a hitch pin, the hitch lock inserts through both the receiver tube of the trailer hitch and the shank of the ball mount. The hitch lock shank can then be secured using the dead bolt lock head. The lock uses a 1/4 activation system and features a chrome-plated finish to ensure solid rust resistance. It comes with two keys and a watertight dust cap to prevent internal corrosion.
