I would look at the tires, assuming they are stock size. The load capacity x 2 is usually a little bit more weight than the axle rating.
So on my Ram, I have a 7000 lb rear axle and the stock tire apacity is 3640x2 or 7280 lbs of capacity. Tires size is 275/70r18.
Really? Then explain how a 3/4 ton with the same "axle" and same wheels and tires as your truck only gets a 6000-6500lb "axle rating"
That seems like more than a "little bit more weight."
Except a 3/4 ton gets smaller rims and tires.
Before the industry went to 17's, 18's and 20's, standard equipment on a 3/4 ton was 245/75R16. A 1 ton SRW would come with 265/75R16, which had about 450lbs more capacity per tire.
