Plan Your Kenworth W900 Upgrade
Work through one area of the truck at a time. Compare the original components and required hardware before choosing a lighting style or chrome finish.
Air-cleaner & breather brackets
Explore housings, exterior light brackets and internal breather-light brackets. Match housing diameter, top style, cutout sizes and mounting points. Confirm which lamps, bezels, grommets and hardware are included.
Interior lighting & cab trim
Coordinate above-door plates and interior light kits with dash screws, gauge trim, vents, controls and steering components. Compare switch layout, cab details and stated model years before ordering.
Visors, hood trim & exhaust
Check curved-windshield and Aerocab requirements for visors, and select bug shields by their stated W900B or W900L application. Match exhaust diameter, elbow angle and divider layout to your current system.
Kenworth W900 Parts & Accessories FAQs
How do I find parts for my Kenworth W900?
Select a product type, then narrow the results by name or SKU. Check the exact W900 variant, year, measurements and mounting requirements in the listing. The filter organizes products; it does not verify fitment.
Are W900A, W900B and W900L parts interchangeable?
Do not assume they are. Headlights, hood trim and other components can have different applications. Match the full model designation, stated years and original part shape before ordering, including for shared Kenworth listings.
Which headlight size should I choose for my W900?
This collection includes a W900A 5.75-inch RetroBright kit and a W900B/W900L 4×6 RetroBright kit. Confirm your installed lamps, housing, connector and beam arrangement against the exact product description before selecting a replacement.
What should I check when choosing a drop visor?
Match the stated cab, windshield shape and model years. Several listings specify curved glass, Aerocab or B-Cab requirements. Check mounting dimensions, depth and light cutouts where applicable.
Will internal breather-light brackets fit every air cleaner?
No. Compare the required diameter, housing and top style with your air cleaner. Some listings specify 15-inch or push-top Donaldson-compatible applications. Confirm the exact mounting requirements and package contents before purchase.
Do air-cleaner brackets and interior plates include lights?
Package contents vary. A bracket or plate with cutouts may be supplied without lamps, while a kit may include specified lights or switches. Check lamp quantities, cutout sizes, wiring and installation hardware.
How do I choose W900 exhaust parts?
Compare pipe diameter, elbow angle, Y-divider layout and attachment points with the existing exhaust. Match the part number and stated application, and check whether clamps or other hardware are sold separately.
What should I check when choosing chrome trim or steering parts?
For trim, match the hood, door, window and bumper configuration and supplied side or quantity. For steering parts, verify the stated year, attachment details and whether the wheel includes a compatible hub and horn button.
