Plan Your Peterbilt 389 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.
Chrome & exterior accessories
Explore window trim, sunvisors, grille and hood parts, air-cleaner components and exhaust hardware. Check dimensions, cab configuration and attachment points before ordering pieces for a coordinated finish.
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 389 Parts & Accessories FAQs
How do I find parts for my Peterbilt 389?
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 389?
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?
Compare the stated cab and roof configuration, door- or cab-mounted mirror arrangement, product dimensions and light cutouts where applicable. Similar-looking trim pieces can have different installation requirements.
How do I choose interior lights and mounting plates?
Check the mounting position, light type, switch arrangement and parts included. This collection has interior light kits as well as separate headliner and above-door plates; a plate-only listing should not be assumed to include lights or wiring.
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.
