What a unique invention. When you have a 1947 through 1959 single rear wheel 3/4 or 1 ton GM truck and need more pulling power, this is the answer. American ingenuity at its best!
This new steel center hub extension includes eight long bolts to reach the original wheel studs. This holds the factory wheel in place and then provides a threaded end for the original eight lug nuts which are holding another matching wheel.
The buyer of this aftermarket kit just had to be sure his new outer tire was the same height as the original inner tire.
