They have these for the new Xterra even though they are not listed yet. I know they have a set for the 2nd gen. Xterra wrapped and ready to ship because they made a set by accident when I ordered mine for the old gen X. The new Pathy in the pics is on the same frame as the 2nd gen. X, so the sliders fit and look the same.

I really like the sliders and they are priced halfway between Calmini and Shrockworks, but they have the same Shrockworks design.

RockyRoad builds mostly for Jeeps and are very well known for their products in the Jeep world. They are just now starting to build for other makes.
