Because the sight line from the kingpin to the axle end extenders may be obstructed by fuel tanks, tool boxes, landing gear, trailer frames, etc. A trailer kingpin extension/pogo stick is used to transfer the kingpin to a position closer to the floor below any obstructions. A 50’ steel tape measure, preferably with 1/16th graduations is used to measure from the trailer kingpin extension tool.
In keeping with our belief of manufacturing heavy duty, high quality axle
alignment equipment, our trailer kingpin extension/pogo stick
weighs 8.5lbs twice as much as any other similar tools on the market.
