Back when this kit was orig made (80's), a way to know the weight carrying capacity of the truck was to look and count the lug nuts. 8 was the sign of a 3/4 ton truck or even a heavier 1 ton, the 3/4 would be either a 20 (chevy) or a 2500 (gmc). And the "3/4 ton" was missleading too, as the vehicles also had an HD (heavy duty) cousin still badged the same that would carry even more. All the 8 lugs means is it is a heavier more capable truck-something I would want when pushing snow. 6 lugs was a 1/2 ton, softer ride, but less heft for work. (Sorry, I am a truck person, if you want a soft ride and are not worried about what a truck will do, then you need to be in a car.)
