Not trying to start anythng but I am sure that I will so I apologize in advance. S.I. Motorsports/Newline only uses a coilover and I believe Steve with the black F150 2wd (Camburg Truck) ran just coil overs for many years. I have been told that Bypasses are only necessary on race trucks for ease of adjustment. I know that I don't even have money for coil overs let allone Coil overs and bypasses so I personaly like the idea of only useing a coil over.
