Peterbilt 389 Exterior Parts

Frequently Asked Questions About Peterbilt 389 Exterior Parts

Will these exterior parts fit my specific Peterbilt 389 model year?

Most of our Peterbilt 389 exterior parts are designed to fit model years 2008 through current production. However, there can be variations between early models (2008-2012) and later models (2013+), particularly with grille surrounds, hood extensions, and fender brackets. Always check the product description for specific year compatibility, or contact our team with your OEM number for verification. Parts like bumpers and visors typically have broader compatibility across all 389 model years.

What is the difference between stainless steel and chrome-plated exterior parts?

Stainless steel parts are made from solid stainless material that maintains its finish throughout, making them more resistant to rust and pitting, especially in harsh weather conditions. Chrome-plated parts have a chrome coating over steel, offering a mirror-like finish at a lower cost but requiring more maintenance to prevent rust if the chrome gets chipped. Stainless steel is ideal for trucks operating in salt-heavy regions, while chrome provides the brightest shine when properly maintained.

Do I need special tools or professional installation for bumpers and grilles?

Most grilles and smaller exterior accessories can be installed with basic hand tools in 1-3 hours. However, bumper installation typically requires at least two people and may need a hoist or jack stands for proper support. Front bumpers often require removal of the old bumper brackets and proper torquing to manufacturer specifications. We recommend professional installation for bumpers to ensure proper alignment and safety, though experienced mechanics can complete the job with standard shop tools.

How do I match aftermarket parts to my truck's existing exterior finish?

When adding new exterior parts, match the finish type across all visible components. Our parts come in four main finishes: mirror-polished stainless, brushed stainless, chrome-plated, and powder-coated options. If your truck has factory chrome bumpers, stick with chrome or polished stainless for new additions. For painted trucks, powder-coated parts can be color-matched. Take photos of your current setup in natural light when ordering to ensure the best match.

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

Based on customer feedback, the most impactful upgrades are, in order: front bumpers (especially when upgrading from painted to chrome/stainless), grille surrounds and inserts, cab and sleeper light panels, and fender guards. A new 20-inch chrome bumper instantly transforms the front appearance, while grille upgrades provide detail that catches the eye. For trucks with sleepers, stainless steel cab extensions and window trim create a cohesive, professional look that enhances resale value.
