Upgrade Your Cab with Peterbilt Truck Interior Accessories

Whether you’re restoring a classic rig or upgrading a newer Peterbilt model with interior Peterbilt cab lights or Peterbilt upholstery kits, you can find the perfect interior accessory to personalize your truck.

Custom Dash Panels, Controls & Instrumentation

A refreshed dash improves both the look of your cab and the ease of operation. We offer everything from small trim pieces to full dash overhauls.

Dash Trim, Gauges & Switch Plates

Replace faded or broken components with chrome knobs, polished gauge bezels, and Peterbilt switch extensions designed for a flawless fit.

Seating, Steering & Gear Shifter Upgrades

Experience better control behind the wheel with ergonomic seating, custom leather-wrapped Peterbilt steering wheels, and auxiliary air shifters. Complete the style upgrade with double-bend stainless shift sticks or billet floor covers.

Peterbilt Cab Restoration & Upholstery

We stock aftermarket and OE cab conversion/restoration parts for your truck whether you have an unibilt or non-unibilt sleeper model, a classic or Next Gen setup, or a traditional 389 or 389 Glider.

Interior Upholstery Kits, Headliners, Trim & Door Panels

From full Peterbilt interior kits to individual door panels with glass watermelon lights, we offer textures like diamond-quilted vinyl and premium Ultra Leather.

Flooring Thresholds & Sill Plates

Upgrade your cab flooring with Peterbilt 379 floor mats and Peterbilt 389 floor mats, as well as vinyl plank wood floors, or smooth aluminum kits. Finish the transition with custom-engraved chrome sill plates.

Maximize Comfort with Peterbilt Interior Sleeper Accessories

When the wheels stop, your sleeper needs to function as a home. Our Peterbilt interior sleeper accessories focus on maximizing space and ensuring high-quality rest.

Sleeper Cabinets, Fridges & Storage Solutions

We stock 3, 4, and 5-drawer storage systems from top brands like Iowa Customs. Many units include built-in refrigerator slots and microwave cabinets with brushed stainless-steel finishes.

Mattresses & Sleeper Comfort Upgrades

Browse through advanced memory foam and cool-action gel mattresses specifically sized for Peterbilt sleepers.

Peterbilt Interior Cab Maintenance Upgrades

A great interior is only as good as the environment inside it. These essential parts keep your cab quiet, dry, and at the perfect temperature.

HVAC, Heat & Insulation

Buy replacement A/C and heater assemblies, dash controllers, and high-performance insulation to stay comfortable in every season. Use HushMat sound deadening to keep road noise where it belongs—outside.

Door Hardware, Electrical & Maintenance Essentials

It’s the small things that keep a truck on the road. We stock the "hardware store" essentials that often break over time.

Door Pockets, Locks & Window Trim

Find model-specific door pockets, window crank screws, and essential weatherstrip door seals.

Shop from 10-amp toggle switches to LED light brackets and clutch pedal springs, we have the small-but-mighty parts required for a safe, functional cab.

Frequently Asked Questions About Peterbilt Interior Parts

Will these interior parts fit my specific Peterbilt model and year?

Most of our Peterbilt interior parts are designed to fit models 379, 389, 567, and 579 from 2005 to present. However, compatibility can vary by specific part and trim level. We recommend checking the product description for exact fitment details or contacting our support team with your OEM number. Parts for older models (pre-2005) may require modifications or custom ordering.

What's the difference between OEM and aftermarket interior parts, and which should I choose?

OEM parts are manufactured to Peterbilt's exact specifications and typically cost 30-50% more than aftermarket options. Our aftermarket parts are made from high-quality ABS plastic, aluminum, or stainless steel and often include improvements like better UV resistance or enhanced durability. For critical components like door panels or dash bezels, many drivers prefer OEM for perfect fit. For accessories like shift knobs, cup holders, or floor mats, aftermarket parts offer excellent value without compromising quality.

How difficult is it to install interior parts myself, and what tools will I need?

Most interior accessories like shift knobs, steering wheel covers, and floor mats can be installed in 15-30 minutes with basic hand tools. Door panels and dash components typically require 1-3 hours and may need panel removal tools, screwdrivers, and socket sets. Complex installations like complete dash replacements or seat installations should be done by professionals. Each product page includes installation difficulty ratings and required tools.

Are chrome and stainless steel interior accessories worth the extra cost over plastic?

Chrome and stainless steel parts typically last 5-10 years longer than plastic alternatives and maintain their appearance better in high-sun environments. They're especially worthwhile for frequently touched items like door handles, shift knobs, and dash trim. However, quality ABS plastic parts with UV coating can be excellent for less visible areas and cost 40-60% less. Consider your budget and how long you plan to keep the truck.

Can I return or exchange interior parts if they don't match my truck's color or style?

Yes, we accept returns on unopened interior parts within 30 days of purchase. For color matching concerns, we recommend ordering color samples first or contacting us with your interior color code. Custom-ordered items, electrical components, and installed parts cannot be returned. We suggest taking photos of your current interior and comparing them with our product images, or requesting additional photos from our team before ordering.
