Affordable. Worth every penny!
Avoid that awkward, "do you know how fast you were going?" Question upon getting pulled over... this is worth it. Easy to install. Easy to program. And everyone who has a non stock wheel or tire combo, needs it.

Round tuit
Had to borrow a PC with windows to update module, and enter vehicle info, old and new tire size. Install instructions are easy. Access to the instrument cluster was no problem. Time to install was about an hour including module update.

Rough Country Speedometer Calibrator
Very pleased with RC’s product. Instructions were good and a couple YouTube videos helped with installation. Corrected speedometer and cruise speed on my Tundra. Recommend leaving the USB cable connected and run to bottom of dash for fine tuning after installation.

Super Easy to Install
Versatile product, can be programmed for any tire size and also for if you change the gearing! Took 10 minutes to set up and install, and can be easily removed and reprogrammed if you make another change. Works well, have verified the speed corrections it made, seems very close, less than 1 off from GPS and radar.
