Did another ride for Father's day last weekend with the wife and kids. I was very impressed with the ground clearance and traction these things get when climbing over wet rocky areas. My buddy's RZR was just spinning up this one rocky section we just idled right up. My only complaint is that the Low Range is geared a bit too high (like many others have noted), especially running 30" tires. It did just fine although it would be a bit better on the machine with some lower gearing. We went over some really rocky sections we would not have been able to clear with stock setup. We made it up the road to the Lake and were the only ones that made it up. One jeep slid off the side of the road and we helped get them back on track.
I'm currently running the PCV that Joey recommended and this thing feels like it has plenty of power to me. The Fox shocks feel great and I really like how quiet it is. The shifting can be a bit jerky, but if you're a good driver and don't mind a bit of shifting down here and there unexpectedly in low range, then its great. I'm going to post some pics and videos below. Keep in mind we didn't take any video of the really rocky sections as we were all tucked in there holding on tight.
