Get an ARB.
BTW, the 2006 Xtrerra is a fully boxed frame and Sandy's is a Ladder frame and not unibody. The ARB's are designed to shore up the frame in front of the front crossmember. An ARB is bulletproof. I believe they are around $800 for an Xterra. A few of the guys in the club have them, I wish they made em for the CJ7, I'd buy one.
