I just bought this kit from 4wheelparts for $140. In addition to the compressor, it includes brackets, switch and wires. I think this kit is a steal. It does not, however, include nylon tubing or air controller switches (front/rear switches). Right now, only my front axle has a locker installed, but I am interested if anybody thinks it would be a good idea to configure both (axles) right now. If so, what additional part numbers do I need?
