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.
