2024 Kenworth T680 Wiper Blade Sizes & Replacement Guide

Maintaining clear visibility in a heavy-duty commercial truck like the 2024 Kenworth T680 is a matter of safety, efficiency, and DOT compliance. Whether you are driving through torrential rain, sleet, or snow, having a fresh set of wiper blades ensures your view of the road remains unobstructed.

Below is your complete guide to the 2024 Kenworth T680 wiper blade sizes, recommended aftermarket brands, and installation instructions.

Quick reference

(Note: The 2024 Kenworth T680 does not feature a rear wiper. OEM part numbers vary based on specific PACCAR dealership availability; check with your local parts counter for exact OEM replacements.)

Best aftermarket replacements

Upgrading to a high-quality aftermarket wiper blade can dramatically improve wiping performance, longevity, and wind resistance—crucial for a vehicle racking up highway miles. Here are the top aftermarket replacements available for the Kenworth T680:

• Bosch ICON: (Premium Price Tier) Designed with a tension spring enclosed in a flexible aerodynamic housing, this beam blade provides superior pressure distribution. Excellent for high-speed highway driving.
• Rain-X Latitude: (Premium Price Tier) A popular beam blade that applies a water-repelling coating to your windshield as it wipes. It clears away rain and snow with ease.
• Trico Force: (Mid-to-Premium Price Tier) Engineered specifically to withstand high winds and crosswinds, making it a fantastic choice for the large windshield of a Class 8 truck.
• Michelin Stealth: (Mid-Range Price Tier) Features a hybrid design, combining the heavy-duty durability of a traditional frame with the aerodynamic cover of a beam blade.
• PIAA Si-Tech: (Premium Price Tier) A silicone flat blade that leaves a hydrophobic layer on the glass. Silicone blades generally outlast standard rubber blades, making them highly cost-effective for fleet drivers in the long run.

Attachment style

The 2024 Kenworth T680 uses a standard J-hook attachment. This is one of the most universal and reliable wiper arm connections on the market. The wiper arm ends in a U-shape (the "hook") that simply loops through the center bridge of the wiper blade and snaps into place.

How to install

Replacing the wiper blades on your T680 is a straightforward task that can be done in minutes at a truck stop or terminal.

1. Lift the wiper arm: Carefully pull the heavy-duty wiper arm away from the windshield until it locks in the upright position.
2. Remove the old blade: Locate the small tab or release button where the blade meets the J-hook. Press it and slide the blade down toward the base of the wiper arm to free it from the hook.
3. Position the new blade: Align the new wiper blade’s adapter with the J-hook on the arm.
4. Lock it in: Slide the J-hook through the adapter and pull the blade firmly upward until you hear or feel a definitive "click."
5. Test the blades: Gently lower the arm back onto the windshield. Turn on the truck’s ignition and run a quick wash cycle to ensure the blades operate smoothly without hitting each other or the windshield trim.

When to replace

For a passenger car, replacing wipers every 6–12 months is standard. However, for a commercial vehicle like the T680 accumulating massive mileage, you may need to replace them more frequently depending on weather exposure. Signs it's time for a replacement include:

• Streaking: Rubber degradation leaves bands of water behind.
• Chattering: The blade skips across the glass instead of smoothly wiping it.
• Splitting: The rubber squeegee is physically detaching from the frame.
