Is there an 8" suspension lift kit for a 2000 dodge ram 1/2 ton quad cab 4wd? Where would be the place to look

With an 8" suspension lift......can I fit 38" mud tires? Do they make an 8" kit or would I need to go with a 6" suspension and 2" body? For the price of the 2" body.....I might as well go 3" body and have a total of 9" of lift. Right?????
