The Frabill tow bar is heavy duty, just extend the tow bar, with square box tubing. Go to a steel supplier, get a piece of box tubing that fits inside and piece with the same outside deminsions as the tow bar. Most suppliers have a bin with cut offs, it's cheaper than buying a full lenght. Drill holes in the tubing to match the factory holes on the tow bar and the receiver thats mounted to the sled, then one thru the extension piece, nut and bolt together.
