You'll never have to worry about breaking your tcase ever again with the cast iron case. Put a 2.28 toybox in front of it, and you regain your sand legs. With the Orion, I'm too slow for the sand now. My top speed in 4th is only 'bout 10 mph. High range only bogs the motor, makes it work too hard in sand. Even at "only" 58:1, I have no problem rock crawling. Someday I may add that Toybox.
