BD 04-06 Ram Top Speed Limiter with Tire Size Calibration

Is the factory 95mph speed limit not fast enough for you? How about 130mph+!!! Sounds great doesn`t it, all this new power and the top end MPH too. Easy underhood installation makes everything a breeze. Just be sure to have those Z rated tires handy.

On the 2004-06 Dodge trucks it can also adjust your speedometer to tire size.

On the high performance 2000.5-03 dodges there is torque management in first gear if you are launching from the lights at the track. Our RAD technology removes this torque limiting function.
