The input shaft (top right) that runs between a 203 reduction box to a 205 transfer case input gear (top left) in a Doubler is very stout, but there is a point where it necks down to 1.29 inches at the 32-spline input. This can be a weak link when running the 203 in low range and the 205 in high gear. The Magnum intermediate shaft (middle and bottom) is massive at 1.63 inches, big enough to be run in any gear without fear of breaking it.
