Swapping your factory tires for larger off-road rubber is a natural part of owning a Jeep. However, if you don’t also recalibrate your speedometer, your Gladiator’s readings won’t be accurate. The last thing you want is a speeding ticket when you thought you were driving safely. Fortunately, CJ’s offers speedometer calibrators that will recalibrate your vehicle’s readout to be precise and accurate. Moreover, you can recalibrate your ECS and shift points for your larger tires as well.

We also offer tuning devices that will let you optimize your throttle pedal response. Select a top-notch product that allows simple plug-and-play installation, granting a versatile range of different options to give you improved response from your Gladiator’s gas pedal.
