Frequently Asked Questions About Freightliner FLC120 Gauges & Switches

Will these gauges and switches fit my Freightliner FLC120?

Most gauges and switches in this category are designed to match the factory fit for the Freightliner FLC120, but dash configurations can vary by model year and trim level. Be sure to check the product specifications and compare part numbers with your existing components before ordering to confirm a proper fit.

Are these replacement parts OEM or aftermarket?

This category includes both OEM and quality aftermarket options. OEM parts are built to original factory specifications for a direct fit and consistent appearance, while aftermarket parts can offer a more budget-friendly alternative. Product listings will indicate which type you are purchasing so you can choose based on your preference and budget.

How do I know which gauge or switch I need to replace?

Start by identifying the specific function of the gauge or switch that is malfunctioning, such as oil pressure, air pressure, voltage, or a specific accessory switch. Matching the old part's number or comparing it visually to the images and descriptions on our site can help ensure you order the correct replacement.

Do these gauges and switches require professional installation?

Many gauges and switches can be installed with basic tools and a bit of mechanical know-how, especially if you are simply swapping an existing part. However, some installations may involve wiring connections behind the dash, so if you are not comfortable working with electrical components, having a qualified technician handle the installation is a good idea.

What should I check if a new gauge or switch is not working after installation?

First, verify that all wiring connections are secure and properly matched to the original setup. Check fuses and related electrical connections, since a faulty gauge or switch is sometimes actually a symptom of a separate electrical issue elsewhere in the truck. If problems persist after confirming the installation, reach out to our customer service team for further assistance.
