Oh the allure of a jacked up ride and big rubber. Four wheelers and jeepers just can't resist rigging their ride and bigger is always better. If you've put on some nice 44 inch tires, your speedometer will no longer read true. You can count on 4 Wheel Parts for top quality speedometer calibrators manufactured by Hypertech, Jet Performance Products and Pro Comp Suspension.
Going Too Fast?
Your vehicle's speedometer is set for the factory wheels. Big wheels cover more ground with a single revolution, so the speedometer thinks your ride is traveling slower than it actually is. Changing the rear axle ratio will have the same effect. Not only is this dangerous, it's illegal. At 4 Wheel Parts we stock speedometer calibrators for Jeeps and trucks that will reset your speedometer, accommodating modifications you have made to your vehicle. We've got calibrators for 2 and 4-door models and 3.8L and 3.6L engines as well as automatic and standard transmissions.
Each speedometer calibrator we sell comes with detailed installation and programming instructions so you can do it yourself. Even a beginning gearhead can handle this job. Basically, you connect the programming cable to the vehicle's diagnostic port, input any changes you made in tire size or rear axle ratio, then follow the prompts on the programmer screen. Pay attention to the details, such as disabling satellite radio and not operating any electrical accessories while the programmer is running. There can be no drain on the battery during programming.
