What kind of Tach RPM Gauge do you need for your custom build? We’re here to help you make the right decision and have you covered with several different versions, including On Dash and In Dash Tachometers that have a long track record of success.
Finding the right RPM Tachometer depends on the type of install you have planned. In Dash tachs typically involve a stock gauge replacement or factory instrument cluster upgrade. On Dash Tachometers are compatible with custom dashboard projects, A-pillar and dash gauge pods and mounting brackets.
If you’re going the In Dash route, stock Tach Gauges tend to run in a 3-3/8” (85mm) size. And we have several different Gas and Diesel Tachometers in this size that read in different RPM ranges.
We also have 3-3/4” (95mm) In Dash Tachometers at a slightly larger size which customers request for custom installations or to replace a larger factory instrument cluster gauge.
For On Dash, we have 2 Inch Tachometers for drivers looking to install a smaller profile RPM Gauge. This Portable Tachometer can be mounted to the A-pillar, dashboard, center console or virtually any location in your car or truck.
We also have 3-3/4” (95mm) On Dash Gas and Diesel Tachometers for a larger Tach RPM Gauge that you can position on your car or truck’s dashboard.
When you’re deciding between In Dash Tachometers vs On Dash Tachometers, it’s a matter of deciding which version is optimal for your specific project.
For complete customization, you can also choose a Gauge Series that gives your Tach Gauge a specific look. We have the incredibly popular 7 Color Series, brand-new Classic Series, 10 Color Digital Series, Double Vision® Series and many other unique styles in stock.
How about creating a Gauge Package for your custom dash, factory instrument cluster replacement and other projects?
