Shrockworks does produce a nice product but be careful what you hit with the bumper wings. I was wheeling my 06 Xterra with the local club and we were headed down a snow covered hill on the last day of our trip. We were all taking it very slow, and I mean very slow when the guy in front stopped at the bottom of the hill to unlock his hubs. The two guys in front of me slid left and right leaving me no choice but to decide which of my friend I wanted to rear end. I chose one and slid right into into his bumper. The passenger front wing is all that made contact with the center of his bumper and I ended up with ~ $8000 worth of damage. I kid you not when I say that I was going under 5mph. Everyone saw it coming and we were all yelling on the cb. It was so slow it was almost comical, until we saw the damage... Something about the angle at which we hit caused the bumper to twist into the body of my truck and ouch!
Not knocking Jim's product but if this kind of crash could cause the kind of damage I received, I would be extra careful around trees and berms.
