    Maintaining clear visibility in a commercial heavy-duty truck like the 2025 Kenworth W900 is an absolute priority for safety on the road. The W900, with its iconic flat split-windshield design, requires reliable wiper blades to handle highway speeds, heavy rain, and harsh winter conditions.

    Below is a complete guide to finding the correct wiper blade sizes, attachment types, and aftermarket replacements for your 2025 Kenworth W900.

    Note: The classic Kenworth W900 cab design generally utilizes 16-inch blades on both the driver and passenger sides, though some aftermarket arms may accommodate up to 18-inch blades. Always measure your current blades before purchasing.

    Best aftermarket replacements

    If you are looking to upgrade from the factory blades or just need a reliable set for your next haul, several premium aftermarket options offer excellent performance and durability.

    • Bosch ICON: (Premium Price Tier) Features an exclusive dual rubber compound and beam design that resists ice and snow build-up, making it perfect for long-haul winter driving.
    • Rain-X Latitude: (Mid-to-High Price Tier) A highly popular beam blade that applies a water-repelling coating to the windshield as it wipes, significantly improving heavy-rain visibility.
    • Trico Force: (Mid Price Tier) Specifically engineered with a swept-wing spoiler to combat wind lift at highway speeds, a great feature for heavy-duty trucks.
    • Michelin Stealth: (Mid Price Tier) A hybrid blade design featuring a smart-flex technology that adapts to the windshield's shape while protecting the blade's joints from debris.
    • PIAA Si-Tech: (Premium Price Tier) A silicone beam blade that lasts much longer than traditional rubber and actively coats the windshield with water-beading silicone with every wipe.

    Attachment style

    Heavy-duty trucks like the 2025 Kenworth W900 typically use a Heavy-Duty Hook (J-hook) or Saddle attachment style, depending on the specific wiper arm configuration installed at the factory. The classic J-hook is the most common and universally supported by aftermarket blade manufacturers, making replacement straightforward whether you are at a truck stop or a dedicated parts counter.

    How to install

    Replacing the wiper blades on your Kenworth W900 is a quick maintenance task that can be done at a rest stop or in the terminal yard.

    1. Pull the wiper arm away: Carefully lift the wiper arm away from the windshield until it locks into the standing position. Caution: Keep a firm grip, as a snapped-back heavy-duty arm can crack the flat glass.
    2. Remove the old blade: Locate the release tab on the wiper blade connector. Press the tab and slide the blade down toward the base of the wiper arm to unhook it.
    3. Position the new blade: Align the new blade's connector with the hook (or saddle) on the wiper arm.
    4. Lock it in place: Pull the blade up into the hook until you hear a distinct "click" confirming it is secure.
    5. Test the wipers: Gently lower the arm back onto the glass and turn on the wipers to ensure they are sweeping smoothly without catching.

    When to replace

    For a commercial truck logging high mileage, standard replacement intervals are often shorter than passenger cars. You should generally replace your wiper blades every 6 to 12 months. However, you should swap them out immediately if you notice:

    • Streaking or smearing across the driver's line of sight.
    • Chattering or skipping over the glass, which indicates the rubber has hardened.
    • Torn, split, or frayed rubber edges.
    • Corrosion on the blade's metal frame.
