Your truck might have the muscle and your hitch might have more capacity than you know what to do with, but what about a ball mount that can keep up? The CURT 2-1/2" adjustable pintle mount is the ideal heavy-duty counterpart to your full-size pickup and class 5 trailer hitch. Rather than using a reducer sleeve or hitch adapter to increase the shank size of your 2" mount, this pintle mount features a solid steel 2-1/2" x 2-1/2" shank. It can accept any mounted CURT pintle hook or ball and pintle combination, and with its 12-1/2" height, it offers up to six height adjustment positions (NOTE: Not for use in rise position; never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). Not only does the 2-1/2" x 2-1/2" pintle mount accommodate a variety of trailers with different coupler heights, but it also allows for use with the heaviest of loads.
