You might have a look at the Convertaball product. Most accessory places have it. It consists of a one inch shank and three drilled out balls that lock to the shank with an integral pin. You can change ball sizes without tools or taking your ballmount out of the reciever. I bought the complete system for sixty bucks, and also purchased two extra shanks for my other ballmounts. This way I have all three ball sizes in 2, 4, and 6 inch drop. This product is signifigantly cheaper if you opt for the chrome version instead of the full stainless set that I opted for. Both versions are rated for 10,000 lbs.
