that is basically THE UCA that most of the xterra guys run when they lift their trucks. im not sure if there was a change to the applications list, but i never noticed that it was also for the pathy (back when i was looking to by an X)
Looks like a worthwhile upgrade for people who take there's offroad. They don't show a price though. Does the OME setup already have something like this part in their kit?
I remember people on The New X talking about PRG Products having them for $550. But they dont have a price listed... i guess you will have to call them.
