    What do these really mean? Is this a rating that the truck can hold, I know the difference between the three, i am just woundering what determines the rating. This post is the result of working midnights and being sleep deprived /forums/images/icons/smile.gif Amazing what a tired brain thinks about.

    Most talk here about different tonnage refers to axles. A 1/2 ton is usually a ten bolt or twelve bolt rear w/ a ten bolt or D44 front axle and six lugs. A 3/4 ton is a 14 bolt rear and a D44 front w/ 8 lugs, and 1 ton is a 14 bolt rear and a D60 front w/ 8 lugs. The ton designation is out of what size four wheel drive came from the factory w/ what axles. I think that's pretty accurate. Hope thats clear enough.

    It doesn't really mean anything. I think those designations originated from old military terminology. If you want to know what kind of work a truck was built to do, look at the GVWR, and the front and rear axle ratings.

    The tonnage of a truck is how strong it is in general. This means frames, springs, master cylinders, and axles. 1 ton trucks ride higher due to their bigger frame, and have bigger axles and master cylinders. A lot of it is the axles but its not all that is involved.
