Also keep in mind that some speedometer shops can make an adapter based upon the difference between your truck's speedometer reading and that of a speedometer ap off of your phone. When I swapped my gears from 4.11 to 3.55, I told the shop what the speedo read at the same what my phone's speedometer ap (Speedbox) read. They produced an adapter which reflected the difference. Dead on!
