Fits 2003-2006 Dodge & Freightliner Sprinter.

This leads me to think that it's a light/medium duty truck - I'm sure if you go to Freightliner's website (who are now Daimler Truck North America) you will be able to see a pic of a Freightliner Sprinter.
Which would lead me to think the shaft it attaches to would be a larger diameter - the average truck driver is probably larger than your average Crossfire driver, and probably less 'gentle'.
