Plan Your Peterbilt 579 Upgrade

Whether you are replacing a worn component or coordinating a lighting and chrome update, compare the exact application before choosing a finish. Use the product-type filter to work through one part of the truck at a time.

Headlights & interior lighting

Compare headlight parts separately from roof cab lights, door turn signals and interior lighting. Check the stated year range, mounting location, connector and lens configuration before choosing replacement lighting for your Peterbilt 579.

Chrome & exterior accessories

Explore bug shields, window trim, illuminated intake grilles, hood mirrors and air-cleaner components. The collection has separate bug-shield listings for 2013–2021 and 2022–2026 Peterbilt 579 applications; match each part’s stated years and mounting details.

Dash & cab upgrades

Find dash screws, gauge trim, controls, door accessories and steering or shifter components. Confirm the stated year range and the shape of the original part; Peterbilt model names alone do not establish interchangeability.

Check the complete parts list

Review quantities, left- or right-hand applications, mounting hardware and wiring requirements. Keep your truck details and photos of the original part available when checking an uncertain fit.

Peterbilt 579 Parts & Accessories FAQs

How do I find parts for my Peterbilt 579?

Choose a product type, then use the name or SKU search to narrow the collection. Check the individual listing for the stated model years, measurements and mounting requirements before ordering. The filter organizes products; it does not confirm fitment.

Will every item in this collection fit every Peterbilt 579?

No. Products can have different year ranges, cab or sleeper requirements, mirror positions and mounting arrangements. Some listings cover shared Peterbilt applications. Match the exact part description to your truck and existing equipment.

Should I choose a headlight assembly or a bulb upgrade?

Start with the headlights already installed on your truck. A replacement assembly, bulb kit and separate headlight cover are different products. Check the lamp configuration, connector, mounting and supplied quantity before selecting an upgrade.

How do I choose Peterbilt 579 bug shields and window trim?

Match the product’s model-year range, hood shape, mirror configuration and dimensions. Bug shields listed for 2013–2021 and 2022–2026 are separate applications, while window trims have their own year ranges and convex-mirror options. Check the exact listing for each part.

What should I check when replacing cab lights or door turn signals?

Confirm the mounting location, listed model years, connectors, lens color and included quantity. Roof cab lights, door turn signals and above-door interior lighting serve different locations and should be matched to the existing equipment separately.

Do air-cleaner brackets include lights and housings?

Check the exact listing. The collection includes housings, brackets, light-cutout brackets and assemblies supplied with specified lights. Verify dimensions and package contents before combining parts.

Are steering wheels, hubs and shift accessories interchangeable?

Match the listed year and application, attachment details and included components. Confirm whether the product includes a hub or horn button, and check the requirements for your existing steering or shifter setup.

Are products sold individually, in pairs or as kits?

The supplied quantity varies. Check the title, selected option and package contents for pairs, bulk items, multi-packs and kits. Compare prices only after confirming the components included.
