What are the most popular aftermarket parts for Kenworth trucks in 2026?

The most popular aftermarket parts for Kenworth trucks are front bumpers, LED headlights, grille guards, hoods and hood fenders, fairing panels, stainless drop visors, and cooling parts such as radiators. Most of them are bought for one of two reasons: the original part is damaged, or the owner wants a sharper look. That splits demand into replacement parts and appearance upgrades. At Tacoma Parts Corporation, which has supplied semi-truck parts since 2012, these categories make up the bulk of Kenworth orders across 11 models, from the T680 Next Gen to the W900.

At Tacoma Parts Corporation, front bumpers for the Kenworth T680 and T680 Next Gen are among the most requested aftermarket items because the bumper takes the first hit from debris and minor impacts.

Repair or upgrade: why Kenworth parts get replaced

Kenworth parts get replaced for two reasons: something broke, or the owner wants the truck to look better. Replacement parts include bumpers, headlights, fairing panels, and cooling components. Appearance upgrades include chrome trim, drop visors, LED headlights, and headlight bezels.

Fleets lean toward replacement parts, because a cracked fairing or a failed radiator keeps a truck off the road. Owner-operators order the same repairs and then add upgrades while the truck is already in the shop. We see it on the parts desk every week, chrome trim, emblems, and lighting often ship in the same order as a structural replacement.

Exterior and front-end parts

Exterior parts account for most Kenworth aftermarket demand because the front end absorbs every impact, from gravel to wildlife. Here is what owners order most and how fitment changes by model.

Bumpers

A Kenworth bumper is the part most likely to need replacement after a collision, and it is also the simplest front-end upgrade. Fitment depends on the model. The 2022+ T680 Next Gen uses a 17" chrome bumper with or without fog light cutouts, including a version with a sensor opening, or a black plastic multi-piece bumper. The 2013–2021 T680 takes a 17" chrome bumper with a radar cutout. One 15" chrome aero bumper fits both the T800 and T880, with or without fog holes. The T660 uses a 14" chrome bumper with a lower lip spoiler. Shop bumpers for the Kenworth T680 Next Gen or Kenworth T800 bumpers.

Grille guards

A grille guard protects the grille, radiator, and headlights from deer, moose, and brush. For the Kenworth T880 (2014–2025) and T800 (1986–2023), we carry the Herd 300. It is built from polished stainless steel, has a patented folding bracket that pivots down for hood access, and installs without drilling. On the T680, fitment depends on the year and the bumper, so the brackets matter as much as the guard. We stock EX-Guard-compatible bracket sets for the 2012–2021 T680 and black grille guards for the 2022+ T680 Next Gen. Compare Kenworth T880 grille guards, grille guards for the Kenworth T680 Next Gen, and grille guard brackets for the Kenworth T680.

Hoods, fenders and fairings

Hoods, hood fenders, and fairing panels are body-shop staples. They crack in collisions, and aerodynamic panels take curb and debris damage. For the W900L, we stock a fiberglass hood shell. For the T680 Next Gen, we carry a fiberglass long hood, sold bare or as a set with the grille, bug screen, air intakes, mirrors, and LED headlights. Hood fenders for the 2012–2021 T680 are sold by side. Kick panels, under-step door panels, and 64" step fairings come individually or as sets.

Grilles, emblems and drop visors

Grilles, emblems, and drop visors are where repair and style meet. The W900L takes a stainless steel grille, while the T880 and 2013–2021 T680 use chrome grille frames with a bug screen. One hood logo emblem fits the T680, T660, T700, T880, and T800. Our 14" drop visor in stainless steel 430 fits T880 sleeper trucks, and we also stock drop visors for the T680. The W900 has been in production since 1961, which is why chrome and a long hood define its look.

At Tacoma Parts Corporation, grille guards for the Kenworth T880 and T800 are among the most requested front-end items because one deer strike can take out the grille, radiator, and headlights at once.

Lighting upgrades: LED headlights and bezels

LED headlights are the most common lighting upgrade on a Kenworth. Owners usually buy them because the old lenses have yellowed or because they are switching from halogen. For the W900, T800, and T600, we stock LED DRL dual-projector headlights with a halo ring. They come in black or chrome housings, sold as a set or by side, with plug-and-play installation and a one-year warranty. Chrome headlight bezels with an amber or white LED strip fit the T400, T600, T800, W900B, and W900L. The 2019-2022 W990 has LED DRL headlights with a sequential turn signal. The T680 Next Gen, T680, and T880 each have their own full LED sets. Replace both sides together for even light output, and ask our parts desk to confirm DOT and SAE marking for the assembly you choose.

At Tacoma Parts Corporation, LED headlights for the Kenworth W900 and T800 are among the most requested lighting items because one set fits both models, plus the T600.

Cooling and under-hood replacements

Radiators and charge air coolers are rarely planned purchases: they fail, and the truck stops. The most useful fact about Kenworth cooling parts is that one part number often covers several models. Radiator N3985001 fits the 2008–2015 T800, 2014–2015 T880, and 2010 W900. Radiator N4020002 fits the 2008–2011 T660, 2008–2015 W900, and 2014 T880. That's why we match cooling parts by part number and year, not by model alone. We also stock coolant reservoir tanks for the 2013–2021 T680 and T880.

At Tacoma Parts Corporation, radiators for the Kenworth T800 and W900 are among the most requested cooling parts because a single part number covers several model years.

Sleeper comfort and seasonal accessories

Sleeper and seasonal accessories keep drivers comfortable on long runs and within idle restrictions. The 50L built-in fridge (YC49B2) fits 1999+ W900, W990, T600, T660, and T800 trucks. Autoterm diesel air heaters warm the cab without idling the engine. In winter, snow chains for semi trucks become a steady order. Year-round, owners add mud flaps, quarter fenders, and wheel caps. Show-truck builders also favor custom exhaust stacks, window chops, and cab lights, which remain a strong trend in the chrome scene.

At Tacoma Parts Corporation, the T680 and T680 Next Gen have the largest selections in our Kenworth catalog because these aero trucks have the most body panels to replace.

How to choose the right part, and why Tacoma Parts

The right Kenworth part matches your model, generation, and year, not just the name on the hood. Check four things before you order:

Model and generation. A 2013-2021 T680 and a 2022+ T680 Next Gen share very few front-end parts.
VIN and year. Radiators and grille guard brackets change from one year range to the next.
Side or set. Headlights, hood fenders, and mirrors are sold as driver side, passenger side, or pairs.
What's included. Check whether brackets and mounting hardware come with the part.

Not sure about fitment? Call (206) 235-2411 with your VIN, Monday through Friday, 8am-5pm PST.

FAQ

What is the most commonly replaced aftermarket part on a Kenworth?

The front bumper. It takes the first hit from road debris, wildlife, and minor collisions, so it tops our list of Kenworth replacement parts. LED headlights and grille guards come next. On aero models such as the T680, fairing and kick panels follow close behind.

What are the most popular upgrades for a Kenworth W900?

The most popular W900 upgrades are LED DRL headlights, chrome headlight bezels with an LED strip, and a stainless steel grille for the W900L. On the repair side, W900 owners also order fiberglass hood shells, radiators, and charge air coolers, often together with an upgrade.

Which aftermarket parts are popular for the Kenworth T680 Next Gen?

For the T680 Next Gen, the most popular parts are 17" chrome bumpers with fog or sensor cutouts, LED headlight sets, fiberglass long hoods, kick and under-step fairing panels, and black grille guards. The Next Gen front end differs from the 2013-2021 T680, so confirm your year before ordering.

Do Kenworth T800 and T880 share aftermarket parts?

Yes, partly. The 15" chrome aero bumper fits both trucks, and radiator N3985001 fits the 2008-2015 T800 and the 2014-2015 T880. Fitment is limited to specific years, and Herd 300 grille guards are sold separately for each model, so always match by year and part number.

Are aftermarket Kenworth parts worth it?

For most repairs and upgrades, yes. Aftermarket parts are available without long sourcing lead times and in finishes the factory rarely offers, such as chrome bezels with LED strips. Match the part to your year and VIN.
