Peterbilt 388 Shift Plates

Frequently Asked Questions About Peterbilt 388 Shift Plates

What is a shift plate and what does it do?

A shift plate is the decorative and functional panel that surrounds the gear shifter boot on the floor or console of your Peterbilt 388. It covers the opening around the shift lever, hides the mounting hardware and wiring underneath, and gives the cab a finished, custom look while protecting the shifter mechanism from dirt and debris.

Will a shift plate fit my Peterbilt 388 without modification?

Shift plates in this category are designed to match the factory shifter opening and mounting pattern used in the Peterbilt 388, so they are built to install using the existing holes and hardware locations. However, transmission type (manual vs. automatic) and shifter style can affect the boot opening size and hole placement, so it is important to confirm your cab's specific shifter configuration before ordering to ensure a proper fit.

What materials and finishes are available?

Shift plates are commonly offered in stainless steel and chrome-plated finishes, with some options featuring textured, engraved, or diamond-plate patterns for added style and grip. Stainless steel options generally offer better long-term resistance to corrosion and wear, while chrome finishes provide a brighter, mirror-like appearance.

How do I install a replacement shift plate?

Most shift plates install by removing the factory screws or fasteners holding the existing plate in place, lifting off the old plate and boot assembly, and securing the new plate using the same mounting points. Some installations may require temporarily removing the shift boot to access underlying hardware. Basic hand tools are typically all that is needed, and no cutting or drilling is usually required when the plate matches your factory configuration.

How do I clean and maintain a shift plate to keep it looking good?

Regular cleaning with a mild soap and water solution, followed by a soft microfiber cloth, will help maintain the finish. For chrome or polished stainless surfaces, using a dedicated metal or chrome polish periodically can help prevent water spots, road grime buildup, and dulling over time. Avoid abrasive pads or harsh chemical cleaners, as they can scratch or discolor the finish.
