Just an added note.....Always consider the entire driveline when it comes to durability. The weakest link in the chain can eventually show itself. Billet steel pinion yoke over OEM, aftermarket mild steel or chrome moly driveshaft tubing over OEM, etc.

I had an OEM pinion yoke actually start to spread over years and hundreds of runs. It hammered the u-joint out during a run and literally destroyed everything from the rear end yoke to the converter and block!
