If you’ve just lifted your Dodge Ram 2500 and slapped on some bigger tires, you’re probably noticing that your speedometer is off. That’s where Rough Country's Speedometer Calibration Device comes in. This little gadget is a game changer for anyone who wants to make sure their speedometer is spot on after a tire upgrade. It’s super easy to use—just plug it into your vehicle's Diagnostic Link Connector Port, and in about 5 to 10 minutes, you’ll have accurate speed readings again. No more guessing if you’re going too fast or too slow!
What I love about this device is that it doesn’t just tweak the readout on your dash. It actually updates your vehicle's ECM (that’s the Engine Control Module for those who might not know) to adjust shift points and recalibrate the electronic stability control. So, if you’ve got larger tires, your truck will handle like it should instead of feeling off-kilter. It’s all about keeping that ride smooth and safe!
Plus, it’s not just a one-trick pony. This calibrator can read and check diagnostic codes, which is super handy for managing those pesky “check engine light” or “service needed” messages. And if you ever need to reset everything back to stock—maybe before servicing your truck—you can do that too. It’s like having a mini mechanic in your glove box!
Here’s the lowdown on the specs: it takes just 5-10 minutes to install, and it’s compatible with Dodge Ram 2500 models from 2006-2009 and 2010-2017, whether you’ve got a 2WD or 4WD setup. With this device, you can clear 35s on a 2010-2017 Ram 2500 with just a bit of trimming. Don’t let that speedometer throw you off; get it calibrated right and hit the road with confidence!
