If you're looking to breathe new life into your 1981-93 Full Size Truck or Ram Charger, this direct-fit instrument system is a game changer. It slots right into the three OEM gauge openings, giving you six analog readouts that not only look sharp but also deliver the kind of performance you need on the road. With two LCD message centers, LED lighting, and the potential for endless expansion, this setup is all about making your ride as functional as it is stylish.

One of the best parts? You can reuse your existing front bezel, so the upgrade feels seamless. Whether you’re keeping your stock drivetrain or going for a full-on conversion, the speedometer is flexible enough to work with mechanical setups or a pre-existing VSS. That means you won’t have to stress about compatibility—it just works.

The MHX Series stands out from the crowd with features that make a real difference. You’ll notice the fully lit needles and backlit faces right away, but it’s the tech under the hood that really sets it apart. We’re talking micro-controlled precision stepper motors and solid-state sensors that provide unmatched accuracy. Plus, the user-customizable display feedback means you can set it up just the way you like it. And let’s not forget the limited lifetime warranty—Dakota Digital has your back for the long haul.

Everything is engineered and manufactured right here in Sioux Falls, South Dakota, and it shows. The MHX Series has really turned the instrumentation game on its head!
