Here are the hard parts that you physically get with the TrailDash kit (PN 438753), but the truth is you get a ton of more features with this nifty little gizmo. The 4.3-inch color touch screen can show you all the info you will probably ever want about your Jeep in real time with a variety of screens, gauge configurations, and colors. So far we love being able to monitor engine coolant temps, transmission temp, and correct the speedo for aftermarket tire sizing and gearing. You can also load power, economy, or towing programs, view tip meters, adjust idle, and control transmission shift points. Did we mention the crawl tune you can load for slow off-road use? You can also view and clear trouble codes, and you can test your Jeep’s performance. See it all at jpmagazine.com/wj_performance_extras.
