URD Speed Unlimiter

$149.00

It’s Back!!!

UPDATE: The unit is now end-user ADJUSTABLE!!


URD reintroduces the URD Speed Unlimiter!

Application:  The URD Speed Unlimter works on the following engine platforms, 5VZ-FE, 1MZ-FE, 2RZ-FE, 3RZ-FE.  If not listed there, we have not tested and verified functionality.

The URD Speed Unlimiter prevents the ECU from engaging the vehicle road speed limiter and limiting the maximum vehicle speed.  The OEMs set the maximum vehicle speed to prevent you from exceeding the maximum rated tire speed that they equip the vehicle with from the factory.  This presents a problem for people that want to use their vehicle in sanctioned off-road racing events even when the vehicle is equipped with high-speed racing tires.

The URD Speed Unlimiter is a frequency clamp that prevents the speed sensor signal from reaching the point where the ECU will engage the vehicle’s road speed limiter and thereby removing that limitation.

This device will defeat the road speed limiter and it is intended for off-road/racing use only and the purchaser must ensure that he installed the correct speed rated tires for the speeds the vehicle will be used at the off-road racing events.

Installation requires the device to be wired into the ECU’s wire harness inside the dash.  If you provide your vehicle information, vehicle, year, and engine, in the comments box in the checkout, we will send you a vehicle specific wiring guide.
