Peterbilt 587 Gauges & Switches

Frequently Asked Questions About Peterbilt 587 Gauges & Switches

Will these gauges and switches fit my Peterbilt 587 without modification?

Products in this category are designed to match the factory dash layout and wiring configuration used in the Peterbilt 587, so they typically install in the existing dash openings without cutting or fabrication. That said, build year and dash configuration can vary slightly, so it is a good idea to compare your existing gauge or switch dimensions and connector type to the product listing before ordering.

Are these OEM parts or aftermarket replacements?

This category includes a mix of OEM and quality aftermarket gauges and switches. Listings typically note whether an item is OEM or aftermarket, along with the brand, so you can choose based on your preference for factory-matched parts versus a more budget-friendly alternative.

Do I need any special tools or wiring knowledge to install a new gauge or switch?

Most gauges and switches are designed for a straightforward swap using basic hand tools, since they connect to the existing wiring harness and mounting points behind the dash. Some jobs may require disconnecting the battery first and having a basic understanding of automotive wiring, so if you are not comfortable working with electrical components, having a qualified technician handle the install is recommended.

How do I know which gauge or switch matches the one currently in my truck?

Check the part number on your existing gauge or switch, if visible, and compare it to the product description or specifications listed on the page. Details like face design, backlighting color, connector type, and function label can also help confirm you are ordering the correct match for your dash.

What is the difference between the finish and lighting options available?

Gauges and switches in this category can vary by dial face style, numbering, and backlight color, while switches may differ in rocker style, symbol, or illumination. These differences are mostly cosmetic and functional preferences, so review the product images and descriptions closely to make sure the option you choose matches the rest of your dash for a consistent look.
