Frequently Asked Questions About Peterbilt Exterior Parts

Will these aftermarket bumpers fit my specific Peterbilt model and year?

Most of our Peterbilt exterior parts are designed to fit specific model ranges. For bumpers, grilles, and fenders, you'll need to know your truck model (379, 389, 567, 579, etc.) and year. For example, 379 and 389 models share many parts, but 2005-2007 379s have different mounting points than earlier models. Always check the product description for exact fitment details, or contact our team with your OEM for verification. We maintain compatibility charts for all major exterior components.

What's the difference between chrome, stainless steel, and aluminum bumpers?

Chrome-plated steel bumpers offer the brightest mirror finish but require regular polishing to prevent rust and pitting. 304 stainless steel bumpers resist corrosion better and maintain their appearance with less maintenance, though they have a slightly different shine than chrome. Aluminum bumpers are the lightest option (saving 40-60 pounds versus steel) and won't rust, but they're more prone to denting. For harsh winter conditions with road salt, stainless steel provides the best long-term value despite the higher upfront cost.

Can I install these bumpers and exterior parts myself, or do I need a shop?

Most bumper installations can be completed in 2-4 hours with basic tools including socket sets, wrenches, and a floor jack or lift. Front bumpers typically require removing 8-12 bolts and disconnecting fog lights if equipped. However, some installations involve air line connections for flip-up bumpers or electrical work for integrated lighting. Fenders and grilles are generally easier DIY projects. Many customers successfully complete these installations in their driveways. Professional installation typically runs $200-400 for bumpers.

How do I match my existing Peterbilt exterior finish when replacing parts?

Peterbilt uses several finish grades across model years. Standard chrome has a mirror finish, while brushed or satin finishes have a duller appearance. When replacing partial components like grille bars or trim pieces, note whether your existing parts have a polished, brushed, or painted finish. For painted parts, we recommend ordering unpainted versions and having them professionally matched to your cab color. Taking photos in natural light helps our team identify the correct finish. Mix-matching chrome with stainless steel is noticeable and not recommended for adjacent parts.

What exterior parts make the biggest visual impact for the money?

Based on customer feedback, replacing a damaged or rusty front bumper provides the most dramatic improvement, followed by grille replacements and fender guards. A new 20-inch chrome bumper transforms the front appearance for $800-1,500. Grille inserts and surrounds offer high impact for $300-600. Adding stainless steel fender guards protects your investment while enhancing appearance for around $200-400 per set. Many customers start with these three areas before moving to smaller trim pieces and accessories.
