I don't have any first hand experience with THESE, but OTR trucks have used a version of these for DECADES and they just don't tear up. Everybody in shops everywhere just hates them because they last forever. lol That oughtta say somethin.
I had a Dana 80 in my last tool truck. Not as tough as my Rockwell's in my other trucks. In 28 years, 5 trucks, and 850,000 miles, the Dana is the only one I had to have rebuilt.
