Towing heavy loads takes everything your V8-powered rig can muster. Sadly, if your ride is equipped with Active Fuel Management (AFM), your towing needs take a backseat to fuel economy. Those power-packed 8 cylinders are cut down to a measly 4 at the most inopportune times, leaving your truck feeling sluggish and unresponsive. Put all of those ponies back to work in seconds by plugging a Range Technologies Active Fuel Management Disable Device into your rig’s diagnostic port. 2-year warranty.
