2016 Kenworth T680 Wiper Blade Sizes & Replacement Guide

Maintaining clear visibility in a heavy-duty truck like the 2016 Kenworth T680 is essential for both driver safety and compliance. With long hauling hours through unpredictable weather, ensuring your rig is equipped with the right wiper blades is a top priority for owner-operators and fleet managers alike. Below is our complete reference guide to finding, selecting, and installing the correct wiper blades for your 2016 Kenworth T680.

Quick reference

For the 2016 Kenworth T680, both the driver and passenger sides utilize the same heavy-duty wiper blade size. As a Class 8 semi-truck, it is not equipped with a rear wiper.

Note: OEM part numbers for Kenworth wiper arms and blades can vary by exact fleet spec and cab configuration. Always verify with your local PACCAR parts counter if you require factory replacements.

Best aftermarket replacements

If you are looking to upgrade from standard factory blades to something that handles sleet, snow, and torrential rain with ease, there are several premium aftermarket options. Keep in mind that heavy-duty trucks often require blades specifically designed for wide-saddle or heavy-duty J-hooks.

• Bosch ICON: (Premium Price) These beam-style blades are legendary for their durability and tension spring technology, which keeps the blade securely pressed against the T680’s massive, curved windshield.
• Rain-X Latitude: (Premium Price) Another excellent beam blade that applies a water-repelling coating to the windshield over time, making it ideal for long hauls in wet climates.
• Trico Force: (Mid-Range Price) Designed with a swept-wing spoiler, the Trico Force is excellent at resisting wind lift, which is particularly beneficial at highway speeds on a heavy-duty rig.
• Michelin Stealth: (Mid-Range Price) A reliable hybrid blade that protects the internal hinges from ice and snow build-up, giving you consistent pressure across the glass.
• PIAA Si-Tech: (Premium Price) Utilizing silicone instead of traditional rubber, these blades offer a significantly longer lifespan and naturally coat the windshield with a hydrophobic layer to bead away water.

Attachment style

The 2016 Kenworth T680 typically utilizes a standard or heavy-duty J-hook attachment. This is one of the most common and user-friendly wiper arm styles. The hook at the end of the metal arm simply wraps around the central pivot pin inside the wiper blade's mounting bracket and locks into place.

How to install

Replacing the wiper blades on your Kenworth T680 is a quick maintenance task that can be done at the truck stop or terminal.

1. Pull the wiper arm away from the windshield. Heavy-duty truck wiper arms have strong springs, so be careful not to let the bare metal arm snap back against the glass, which can cause a catastrophic crack.
2. Locate the release tab on the underside of the wiper blade where it meets the J-hook.
3. Press the tab and firmly push the wiper blade down toward the base of the wiper arm to unhook it.
4. Slide the old blade off the arm.
5. Insert the new blade by sliding the J-hook through the new blade’s mounting bracket.
6. Pull the blade up until you hear or feel a solid "click," indicating the lock is engaged.
7. Gently lower the wiper arm back onto the windshield. Repeat for the passenger side.

When to replace

For commercial vehicles, we recommend replacing wiper blades every 6 to 12 months. However, because heavy-duty trucks rack up miles faster than passenger cars, you should replace them sooner if you notice:

• Streaking: Leaving bands of water across your line of sight.
• Chattering: Skipping or bouncing across the glass, which indicates the rubber has stiffened.
• Splitting: Visible tears in the rubber squeegee from sun exposure or ice damage.
