How much weight gain from adding a Dana and roll cage.

I have seen axel tubes in Dana 60's anywhere from 5/16'' to a hair over 1/2'' depending what it came out of . So weight varies .

.... and the thicker axle tubes make up for the lack of rear brace you find on hi-horsepower 9" and 8 3/4 applications.. Kind of a pick-your-poison. Thick tubes to keep the housing straight, or lightweight tubes for minimum weight penalty.
