Plan Your Kenworth T660 Upgrade
Start with the part you need, then match its application to your truck’s year and existing equipment. Use the product-type filter to compare one group at a time.
Exterior lighting & chrome trim
Explore fender signal lights, illuminated air-intake accents, emblem trim, bug shields and window accessories. Match dimensions, mounting points and the original part shape; similar-looking pieces can have different applications.
Interior lighting & cab accessories
Coordinate watermelon-light plates and kits with dash screws, gauge bezels, controls, door trim and floor mats. Confirm cab details, cutouts, switch layout and supplied quantities for each component.
Mounting & package contents
Review bracket requirements for grille guards, mounting dimensions for air-cleaner parts, and the exact application of step trim and steering hubs. Check whether hardware, lamps and wiring are included or listed separately.
Kenworth T660 Parts & Accessories FAQs
How do I find parts for my Kenworth T660?
Select a product type and narrow the results using a product name or SKU. Compare the individual listing’s model years, dimensions and mounting requirements with your truck. The filter organizes the collection; it does not verify fitment.
Will every product here fit every T660 model year?
No. Headlights, trim, cab components and shared Kenworth parts can have different year ranges and installation requirements. Some products name another model in the title. Confirm the exact application in the product description before ordering.
What should I compare when buying T660 headlights?
Check the stated years, left- or right-hand application, lamp technology, connectors and mounting points. Compare turn-signal and position-light features separately from the main headlight function, and confirm whether the listing supplies one assembly or a pair.
Are fog-light covers the same as replacement fog lights?
No. A cover, trim piece or decorative light assembly is different from a replacement fog lamp. Read the listing to confirm its function, included components and mounting requirements before replacing an existing fog light.
How do I choose window trim and visors for a T660?
Match the cab and door configuration, mirror arrangement, dimensions and stated model years. Check daylight-door requirements and sleeper-window details where listed; do not rely on the truck brand alone.
Do grille guards include the correct mounting brackets?
Check the exact kit and bracket application. Some listings include a guard and bracket kit for a specified vehicle. Confirm compatibility with your T660, bumper configuration and existing mounting points before ordering.
Do interior light plates and air-cleaner brackets include lights?
Package contents vary. A plate or bracket with light cutouts may be supplied without lamps, while a kit may include specified lights. Check hole sizes, lamp quantities, wiring and mounting hardware in the individual listing.
Are T660 accessories sold individually, in pairs or as kits?
All three formats appear in the collection. Review the title, selected option and package contents for pairs, multi-packs and kits. Compare prices after checking the supplied quantity and any additional parts required.
