If you're running a Kenworth T680, you already know this truck is built for the long haul. But even the toughest rigs need quality aftermarket parts to stay in peak condition. Whether you're looking to replace worn components or upgrade your rig's appearance, Kenworth T680 parts are essential investments for any owner-operator or fleet manager. At EverTrust Truck Parts, we stock OEM-quality replacements and upgrades that keep your T680 looking sharp and running strong—all available at prices that beat the competition.

Ready to upgrade your rig? Here are the 10 best Kenworth T680 aftermarket parts every owner needs to know about.

1. Chrome Headlight Assembly

Your headlights are the first thing people see when they look at your truck, and they're critical for safety during those late-night drives. The Chrome Headlight Assembly for the T680 delivers premium visibility and a classic look that gives your rig that polished, professional appearance. This unit is built to last and maintains consistent beam output even after thousands of miles on the road.

The chrome finish resists corrosion and weathering, meaning your investment stays looking new year after year. Installation is straightforward on the T680 platform, and the assembly is fully compatible with OEM electrical systems. Many owner-operators appreciate the plug-and-play design—no rewiring or custom brackets needed. Whether you're replacing a damaged unit or upgrading from dull factory lights, this chrome assembly elevates your truck's curb appeal while keeping you safe on the road.

2. Black Housing Headlight Assembly

Want a more aggressive, modern look for your T680? The Black Housing Headlight Assembly is your answer. This setup gives your truck that contemporary street presence while maintaining full OEM compatibility and reliability. The black housing contrasts perfectly with chrome bumpers and trim, creating a sleek, purpose-built appearance that turns heads at the truck stop.

Performance-wise, these headlights deliver excellent light output with modern lens technology that maximizes visibility without glare. The sealed housing keeps moisture and dust out, extending the life of your bulbs and ensuring consistent performance in any weather.

3. LED DRL Headlight Assembly

LED technology has revolutionized truck lighting, and the LED DRL Headlight Assembly for your T680 brings that efficiency and longevity to your rig. Daytime running lights (DRLs) aren't just about style—they make your truck visible to other motorists during daylight hours, adding a safety layer that standard headlights don't provide during the day. The LED setup draws minimal power from your electrical system, leaving more juice for other essential components.

These assemblies last tens of thousands of hours longer than traditional incandescent bulbs, meaning you're replacing them less frequently and spending less time in the shop. The DRL rings provide a distinctive look that other drivers recognize instantly, which can improve your visibility profile on congested highways. Whether you're looking to improve safety margins or simply want your T680 to stand out with modern technology, LED DRLs are a worthwhile upgrade. The energy efficiency also means lower overall power draw, which can positively impact fuel consumption on long hauls.

4. Next Gen Headlight (P54-6157-100, P54-6157-100R)

If you want the absolute best in T680 lighting technology, the Next Gen Headlight represents Kenworth's latest engineering. These units feature advanced optics that provide superior beam distribution and reduced glare, making nighttime driving significantly safer.

The sealed, precision-molded housing ensures durability against the elements and rough road conditions. Owner-operators report that the improved visibility from these units actually reduces eye strain during long night drives, making them an investment in both safety and comfort. The Next Gen design is compatible with all T680 model years that use the standard headlight mounting, and installation is as simple as your basic chrome or black housing counterparts.
