One noticable difference is that it runs much smoother on high speed gravel and dirt roads. No bottoming out any more, and I cary tons of weight back in the rear. If you spend lots of time on the gravel, I'd recommend the suspension even if you kept everything else stock.

Another noticable difference is a crummy ride on the interstate. As with any real off road vehicle, road noise increases with the tires. The higher center of gravity tends to make it a little less stable; It definately takes a little more steering to keep it in the lane at interstate speeds.

But I'm a guy. I don't care about stuff like that. Looking at the beefy thing in the parking lot gives me more enjoyment than any smooth ride ever did. If you care about smooth ride...well, I probably wouldn't do any of these mods.
