WHAT YOU GET: As shown in the product picture, you will receive a drop shank which fits into a standard 2" receiver hitch, the lowering mechanism, the hitch ball holder, a 2" hitch ball, and four pins and clips. You will need to use your road hitch's pin/clip for your 2" receiver. The Tuck Hitch lowering mechanism is NOT to be used on the road/highway and is only intended to be used for a very short distance in order to back your boat into a garage and to take it out of your garage. 

The amount of actual clearance gained for your boat/garage door combination will be determined by your boat type and height limitation position in relation to your boat trailer axle. Check out the About/FAQ page to better understand if the Tuck-Hitch will work for your situation.
