Hey, I wonder what you guys think about the leveling kit from Top Gunz Customs. It gives the X about a 2" lift and they are pretty cheap at about $89.95 (w/shipping). I wanted some more front ground clearance and I was also hoping that this might improve the ride (make it less choppy) a little bit. Anyways here the link.

Check this link out will give you a lot of info. Clicky Lift Options

The problem is that is a "leveling" kit for the Frontier. If you install it on an Xterrer it will not "level" it, it will make the front sit higher than the rear.
