BD Diesel Top Speed Eliminator w/Tire Calibration - 2004-2005 Dodge 1057655

Is your factory speed limiter hampering performance at the top end of the track? The Top Speed Eliminator Increases top speed to over 130 mph, and allows adjustment for larger tires. 2000.5-2003 Dodge-Cummins Top Speed Eliminators also remove the torque-limiting function in first gear for more off-the-line power. Easy under-hood installation.
