We've been in this business since 2013, and one thing hasn't changed - fleet managers and owner-operators don't have time for downtime. A front-end collision with a deer, debris, or road hazard at highway speed can put a rig out of commission for days, cost thousands in bodywork, and knock a truck off its route at the worst possible moment. That's exactly the kind of problem a quality grille guard is built to prevent. At kozakparts.com , we stock a solid selection of grille guards purpose-built for the Kenworth T680, sourced from trusted names like Kozak, EX-Guard, and Herd - brands that have a real track record on the road, not just in catalog photos. If you're running a T680 and you haven't thought about front-end protection, it's worth a few minutes of your time.
Not every guard on the market is worth your money, and we're not going to pretend otherwise. The T680 is a serious workhorse platform - it hauls heavy, logs serious mileage, and works in conditions that most vehicles never see. The protection you bolt to its front end needs to match that standard. A lot of what's out there looks decent in a product photo but doesn't perform once it's actually on the truck and taking the kinds of impacts that happen out on the road. Here's what actually matters when you're choosing:
Beyond the T680 specifically, our catalog covers the T880 parts as well - if you manage a mixed fleet, you don't need to shop in multiple places.
The T680 grille guard category covers several distinct configurations, and the right one depends on how you're using the truck and how much coverage you actually need.
Standard front grille guards mount to the existing bumper and add a protective steel cage in front of the grille and headlight assembly. These are consistently our most popular option - they add meaningful protection without changing the truck's footprint or making it harder to maneuver. Available in both chrome and black, with or without integrated light mounts. Most operators running highway freight start here.
For routes where deer strikes are a real and recurring risk - rural interstates, mountain corridors, anywhere you're moving at speed through open country at dawn or dusk - a t660 deer guard style provides substantially more protection. These are the full herd-style bar systems: heavier tube gauge, extended forward reach, designed specifically to deflect large animals away from the engine compartment and cab rather than just absorbing the hit. The Herd 200 and Herd 300 series are well established in this category, and we carry parts for both on the T680 platform.If you've had a deer strike before, you already know why this matters.
Operators who want the most integrated solution go with a Kenworth t660 bumper guard configuration. These units combine the front guard structure with the bumper itself - one cohesive piece of steel instead of a guard mounted over a separate bumper. The result is a cleaner look, tighter fitment, and more coverage across the lower front section of the truck. It's a more substantial upgrade, but for trucks that work in rough conditions, it's hard to argue with the results.
A t660 brush guard adds lateral protection that a standard front grille guard doesn't address. These extend coverage to the sides of the bumper and are built for environments where the threat isn't only coming from straight ahead. Less common in long-haul fleets, essential for certain work applications.
We also carry Kenworth t660 grille guards - guards originally engineered for the T660 platform. Depending on the specific unit and model year, some of these cross-apply to related Kenworth platforms. Fitment should always be confirmed before ordering; our team can walk you through that over the phone in a few minutes.
Regardless of which configuration you go with, the common thread across everything we sell in this category is that it's built to actually do the job. We don't stock light-duty guards dressed up with heavy-duty marketing copy. What we list is what we'd put on our own trucks.
In stock. Ships the same day.
If a product shows in stock on kozakparts.com , it is physically sitting on our shelves and ready to go. Orders placed by 2 PM Pacific ship the same day. We cover all 48 contiguous states with full tracking on every order.
Every guard we sell goes through in-house quality inspection before it ships. That means you're not opening a crate to find bent tubes, missing hardware, or welds that looked fine in a photo but don't hold up in person. If something doesn't meet standard, it doesn't ship. If something isn't right on your end, we make it right - our return process is straightforward and our support team is reachable by phone and email.
We've served more than 30,000 customers since we started - solo owner-operators running one truck, fleet managers sourcing parts for dozens of rigs, body shops that need reliable aftermarket components at consistent quality. The T680 grille guard category is one of our strongest because it's one of the most requested. These trucks are everywhere on American highways, and the operators running them take front-end protection seriously.
