Peterbilt 379 Shift Plates

Frequently Asked Questions About Peterbilt 379 Shift Plates

What is a shift plate and what does it do on my Peterbilt 379?

A shift plate is the metal or decorative panel that surrounds the gear shifter boot on the floor or console of your truck. It covers the opening where the shifter linkage passes through, hides wiring and mechanical components underneath, and gives the shifter area a finished, custom look. Many Peterbilt 379 owners upgrade this part for both appearance and durability.

Will a shift plate fit my specific Peterbilt 379 setup?

Shift plates are generally designed to match the factory shifter opening and mounting pattern for the Peterbilt 379, but fit can vary depending on your transmission type (manual vs. automated) and whether your truck has the standard or optional shifter console. Always check the listed dimensions and hole pattern against your existing plate before ordering, and reach out to our team if you are unsure about compatibility.

What materials and finishes are available for shift plates?

Shift plates are commonly available in stainless steel, chrome-plated steel, and aluminum, with finish options ranging from polished mirror chrome to brushed or diamond-plate textures. Stainless and chrome options tend to hold up well against wear from boots, road grime, and cleaning, while offering a range of looks from subtle to show-truck bold.

How do I install a replacement shift plate?

Most shift plates are a direct bolt-on or screw-on replacement for the factory piece. Installation typically involves removing the shifter boot, unscrewing or unbolting the old plate, positioning the new plate over the shifter opening, and securing it with the provided fasteners before reattaching the boot. No cutting or drilling is usually required if the plate is designed for a direct fit, but always follow any instructions included with your specific product.

How do I keep my shift plate looking good over time?

Regular wiping with a soft cloth and mild cleaner will keep chrome and stainless plates free of grime and fingerprints. Avoid abrasive pads or harsh chemicals that can dull the finish or scratch polished surfaces. For textured or diamond-plate finishes, a soft brush can help remove buildup from grooves without damaging the surface.
