Plan Your Peterbilt 379 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 4×6 headlights, complete assemblies, mounting arms and turn-signal parts separately from interior light kits. Match the lamp configuration, connections, mounting points and supplied quantity to the equipment on your truck.
Chrome & exterior accessories
Compare window trim, sunvisors, grille parts, air-cleaner components and exhaust elbows or clamps. Check short- or long-hood applications, standard low-roof or UltraCab fitment, pipe diameter and attachment points before ordering.
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 379 Parts & Accessories FAQs
How do I find parts for my Peterbilt 379?
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 379?
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.
What should I check when ordering window trim or a sunvisor?
Match the listed year range and standard low-roof or UltraCab configuration, then check mirror position, dimensions and light cutouts where applicable. For hood-mounted accessories, confirm short- or long-hood fitment. Similar-looking pieces can have different mounting requirements.
What should I check when buying Peterbilt 379 exhaust parts?
Match pipe diameter, elbow angle, inlet and outlet dimensions, cab application and the required clamp style. Exhaust elbows, clamps and brackets are separate components unless the listing explicitly includes them together. Check the existing system before choosing replacement parts.
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.
