The lower first gear on the 200-4R already has a nice overall ratio with the 3.55.

Another thing to consider is that that while the engine is operating at a lower RPM, the 3.90 or 4.11 pinion gears will be hauling at higher cruising speeds. Going to be a lot of heat generated in the pumpkin on extended runs, and even if the rearend is quiet at first, I wonder if there might be accelerated wear? I would be inclined to stop at the 3.73 ratio.

I've had pretty good results with Yukon, mixed results with U.S. Gear, and bad results with the no-name ebay units that we tried.

X2 Lots of people miss that heat in the rear center section when they try to run around with 4.11/4.33/4.56 type gears with tall tires on the street. The really large tires (20" crap) seem to lower the temp to livable numbers.
