Peterbilt 389 Glider Shift Plates

Frequently Asked Questions About Peterbilt 389 Glider Shift Plates

What is a glider shift plate and what does it do?

A glider shift plate is the metal cover that surrounds the base of the shifter where it comes up through the floor or console of your Peterbilt 389. It covers the opening around the shift lever, protects the linkage below from dirt and debris, and gives the cab a finished, factory-style appearance.

Will this shift plate fit my specific Peterbilt 389 glider setup?

Shift plates are designed to match the floor or console layout of a Peterbilt 389 glider kit, but hole spacing, shifter boot cutouts, and mounting points can vary depending on the transmission and floor configuration used when the truck was built. Compare the dimensions and bolt pattern listed on the product page to your existing plate before ordering, and reach out to us if you are unsure about fitment.

What materials and finishes are these shift plates available in?

Most glider shift plates are made from stainless steel or aluminum and come in a range of finishes, including polished, brushed, and diamond plate textures. Stainless steel generally holds up better against corrosion and daily wear, while aluminum offers a lighter weight option. Choose the finish that best matches the rest of your interior trim.

How do I install a replacement shift plate?

Installation typically involves removing the shifter boot, unbolting or unscrewing the old plate, and securing the new one in its place using the existing mounting holes. Most plates are a direct bolt-in replacement and do not require cutting or drilling, but you should always disconnect the shifter boot carefully to avoid tearing it during removal.

Can a shift plate help reduce noise or vibration in the cab?

A properly fitted shift plate helps close off the opening around the shifter, which can reduce road noise, dust, and drafts coming up through the floor compared to a cracked, warped, or missing plate. It is not designed to address drivetrain vibration, but a snug, well-seated plate does improve overall cab comfort.
