Where to buy Kenworth truck parts online: dealer vs. aftermarket

The fastest and most affordable way to buy Kenworth parts online for body, front-end, lighting and cooling repairs is a specialized heavy-duty aftermarket supplier that lists each part by model, year and side and ships from its own stock. A Kenworth (KW) dealer is still the right call for warranty work, programmed electronics, emissions systems and engine internals. Tacoma Parts Corporation, a semi-truck parts supplier since 2012, stocks new aftermarket parts for 11 Kenworth models, from the T680 Next Gen to the W900. In-stock orders ship within 24 hours.

Where to buy Kenworth parts online: 4 options compared

For exterior, lighting and cooling repairs, a specialized aftermarket supplier gives the best balance of speed and cost, while the dealer remains the choice for warranty and electronics.

Channel	Best for	Typical wait	Price	Watch out for
Kenworth dealer and Online Parts Counter	Warranty repairs, electronics, engine and transmission	Same or next day if the local dealer has it; special order if not	Highest	Stock and pricing differ from dealer to dealer
Specialized aftermarket supplier (Tacoma Parts Corporation)	Body panels, front end, lighting, cooling, accessories	Handed to the carrier within 24 hours from stock	Mid-range	No warranty-covered or programmed parts
General online marketplaces	Small items and price checks	Depends on the seller	Varies widely	Fitment by year and model is not guaranteed
Salvage yards	Discontinued parts for older trucks	Depends on the yard	Lowest	Condition and completeness are unpredictable

Genuine, TRP or aftermarket: what the labels mean

"Genuine" means a factory part sold through the Kenworth dealer network, while "aftermarket" means a new part from an independent manufacturer. These are the four labels you will see when shopping for Kenworth parts:

PACCAR Genuine Parts: factory parts for Kenworth trucks, sold through Kenworth dealers.
TRP: a PACCAR parts line for all truck makes, also sold through dealers.
Aftermarket: new parts from independent manufacturers, built to fit the factory mounting points, often in several finishes such as chrome or black. This is what Tacoma Parts Corporation sells.
Used / salvage: parts removed from other trucks. We do not sell them.

Aftermarket means a different supply chain and a different price point, not automatically lower quality. What matters is correct fitment and a clear year range on the listing. To be direct: we don't sell PACCAR Genuine or TRP parts. For a brand-by-brand breakdown, read our guide to OEM vs aftermarket semi-truck parts.

When a Kenworth dealer is the right choice

A Kenworth dealer is the right choice for warranty repairs, programmable modules, emissions aftertreatment, PACCAR MX and Cummins engine internals, and transmissions. Furthermore, the system shows what is in stock at the local dealer, making it a good starting point for such work. Dealership specialists can also program and install the modules during the same visit - an advantage that ordering parts online cannot offer.

Which Kenworth parts are worth buying aftermarket

Aftermarket Kenworth parts make the most sense for exterior, lighting and cooling components. These parts fail from road damage rather than wear, bolt to factory mounting points and are usually needed fast.

Bumpers and front-end protection

Bumpers are worth buying aftermarket because the exact configuration you need is usually on the shelf, not on special order. Bumpers for the Kenworth T680 Next Gen come in chrome or black, with or without fog light cutouts. The range includes 17-inch chrome versions with a sensor cutout. Covers, reinforcements and spoilers are sold separately. For extra protection, grille guards for the Kenworth T680 Next Gen and EX-Guard grille guards mount with brackets matched to the model year and bumper type.

Hoods, hood fenders and fairings

Hoods are worth buying aftermarket because a complete assembly can ship from stock instead of being built to order. A fiberglass long hood for the Kenworth T680 Next Gen is sold bare or as a set. The set adds grille, bug screen, air intakes, mirrors and LED headlights, which saves labor. Hoods for the Kenworth T680 Next Gen are listed next to latches and vent grilles. Fairing panels for the Kenworth T680 Next Gen, steps and kick panels come as driver side, passenger side or a matched set.

Headlights and lighting

LED headlight assemblies are a common aftermarket replacement because one set restores both sides at once. The Kenworth T680 2013-2021 and the T680 Next Gen use different headlight housings, so each model has its own sets. Before buying any lamp, check the listing for DOT and SAE markings. LED headlights for the Kenworth T680 Next Gen are sold as matched sets, and we recommend replacing both sides together.

Grilles, mirrors and chrome trim

Grilles, mirrors and trim are worth buying aftermarket because they take regular hits at loading docks and from road debris. The Kenworth T880 has a chrome grille frame with bug screen. The 2013–2021 T680 and the T880 share the same door mirror and mirror cover listings. Mirrors for the Kenworth T680 Next Gen are listed separately. On the Kenworth W900, chrome is part of the truck's identity. Stainless W900L grilles, chrome headlight bezels and grilles and logo emblems for the Kenworth W900 are core catalog items.

Cooling

Radiators, charge air coolers and water pumps are usually replaced after a failure, so stock on hand matters most. Each radiator listing shows a reference number and exact fitment. For example, radiator N3985001 fits the 2008–2015 T800, 2014–2015 T880 and 2010 W900. Match core size and hose connections before ordering. Start with radiators for the Kenworth T680 Next Gen or water pumps for the Kenworth T680.

Kenworth parts by model: what we stock

Tacoma Parts Corporation carries aftermarket Kenworth parts for 11 models. Aerodynamic trucks lean on body panels and fairings, classic long-hoods on chrome and lighting.

Model	Years / generation	Main categories in stock	Link
T680 Next Gen	2022+	Bumpers with fog or sensor cutouts, LED headlights, hoods, fairing and kick panels, grille guards, radiators	Kenworth T680 Next Gen parts
T680	2013-2021	Bumpers, grilles, fairings, hood fenders, LED headlights, fog lights, mirrors	Kenworth T680 parts
T880	Varies by part, listed from 2013	LED headlights, bumpers, grilles, grille guards, radiators, mirrors, drop visors	Kenworth T880 parts
W900	W900L and W900B	Hoods, stainless grilles, logo emblems, LED headlights, chrome bezels, radiators	Kenworth W900 parts
W990	2019-2022	LED headlights, bumpers, built-in fridges	Kenworth W990 parts
T800	Varies by part	Bumpers, LED headlights, mirrors, grille guards, radiators, charge air coolers	Kenworth T800 parts
T660, T600, T700, T400, T370	Varies by part	Exterior, lighting, mirrors, cab parts	All Kenworth models

Headlights, bumpers, hoods and fairings for the T680 Next Gen differ from those for the 2013-2021 T680, so the catalog lists them separately. Check your model year first.

How to order the right Kenworth part the first time

To order the right Kenworth part the first time, confirm six details before checkout. A wrong year, a wrong side or a missing bracket is what usually stops a repair.

Model and year range: T680 (2013-2021) or T680 Next Gen (2022+).
VIN for build-dependent parts: radar or sensor, fog lights, hood length.
Side: driver or passenger, a single part or a matched set.
What's in the box: whether brackets, hardware and trims are included or sold separately.
Lighting markings: DOT and SAE on any headlight or lamp.
Delivery address: large parts ship by freight and need a commercial address or terminal pickup.

Every Kenworth listing on our site names the year range and, where relevant, the side. A quick check against your truck catches most mismatches.

Not sure? Call (206) 235-2411 with your VIN, Mon–Fri 8am–5pm PST, and we'll confirm the part number before it ships.

FAQ

Where is the best place to buy Kenworth truck parts online?

A specialized heavy-duty aftermarket supplier is the best place to buy Kenworth parts online for body, front-end, lighting and cooling repairs. It lists parts by model, year and side and ships from stock. For warranty work, engine internals and programmed electronics, use a Kenworth dealer or the Kenworth Online Parts Counter.

Are aftermarket Kenworth parts as good as PACCAR Genuine parts?

Yes, for most exterior, lighting and cooling components, as long as the part matches your model year and factory mounting points. A quality aftermarket bumper, hood or headlight does the same job at a different price point. For warranty repairs, emissions systems and programmed electronics, PACCAR Genuine Parts from a dealer remain the right choice.

Can I look up Kenworth parts by VIN?

Yes. The Kenworth Online Parts Counter searches genuine parts by VIN and part number. For aftermarket parts, call our parts desk at (206) 235-2411 with your VIN. We will confirm radar or sensor cutouts, fog lights and hood length before the order ships.

Do Kenworth T680 and T680 Next Gen parts interchange?

No, this does not apply to most front-end components. Headlights, bumpers, hoods, and fairing panels for the T680 Next Gen (2022 and newer) differ from those for the 2013-2021 T680 models, therefore, separate catalog listings exist for each generation. Universal parts, such as mud flaps and wiper blades, are compatible with both versions. Always check the model year range specified in the product description.

Tacoma Parts Corporation carries aftermarket parts for 11 Kenworth models: T680 Next Gen, T680, T660, T800, T880, T700, T600, T400, T370, W900 and W990. Coverage is deepest for the T680 and T680 Next Gen, with body, lighting and cooling parts.
