I used this in the front axle of the f350. It fit well, make sure you have patience when installing because lining up the parts can be tricky if your a first timer.

Fast shipping, nice unit, great quality. Fantastic deal on Amazon. Pulled the first shaft and it wasn't an HD axle, the rear end was regular D60 30 spline. I contacted the folks in Washington state and they sold me the 30 spline ends for a really great price so I can keep the 35's when I ream the spindle and drop in the larger axles. For a breadbox, you can't beat the great deal for Spartan quality and Amazon prices.

Super easy install. Tolerances came out great. I went on my first wheeling trip and the locker worked flawlessly. Full size truck on 44" boggers 450hp engine. And a 4 speed manual.
