I had these on the front of my X for awhile and they were soft because of the valving. I decided that I was just going to buy some ranchos because it was cheaper then to revalve.. I talked with bilstein on this many times. They said 360/80 would be good if you were to revalve them yourselves but he said for the front of an xterra he would do a custom 400/104.. or was it 440/104 i cant remember for sure. Just call up Shane at bilstein. I need to sell them now.. let me know if you're looking to buy. Theyre 2 months old.
