Thanks alot guy!! This was a really fun sled to build. I was really impressed with how the Quantum Tunnel turned out... And for being Ron and jeff's first XP tunnel it mounted up very well. Another nice thing about this tunnel is it weighs the same as a 163 stock xp tunnel. Anyone that wants a Strong and well build Mountian Tunnel these are the ones to get. I know how important shaving weight is but i ride my machines decenty hard and want something that will handle some abuse. haha Give these guys a call for a tunnel
