I saw a 4" diameter driveshaft out of a single-drive Peterbilt with a 425 Cat in it that looked like an hourglass. The rig was hooked up to a set of double grain trailers and stuck in a muddy field, and when the driver revved it up and dumped the clutch it made 4 full turns of the driveshaft before the slip yoke pulled off the spline!
