2018 Volvo VNL Wiper Blade Sizes & Replacement Guide

When you are running freight across the country in a 2018 Volvo VNL, visibility is everything. Driving a Class 8 heavy-duty truck through rain, snow, and road spray means your wiper blades take an absolute beating. Running old, worn-out wipers isn't just an annoyance; it is a major safety hazard when navigating heavy traffic or severe weather.

To help you get back on the road safely, we have compiled everything you need to know about replacing the wiper blades on your 2018 Volvo VNL.

Quick reference

For the 2018 Volvo VNL, the wiper blade lengths are symmetrical for both the driver and passenger sides. Commercial trucks like the VNL do not come equipped with rear windshield wipers.

(Note: Always verify your specific fleet configuration, as some modified sun visors or aftermarket aerodynamic packages might require slightly different sizing. OEM part numbers change frequently for HD trucks; check with your local Volvo Trucks dealer using your VIN for the exact factory replacement part number).

Best aftermarket replacements

While factory Volvo blades are excellent, many owner-operators and fleets prefer premium aftermarket upgrades for better longevity and performance. Here are some top-tier cross-references suitable for heavy-duty applications, categorized by price tier:

• Bosch ICON: (Premium) These beam-style blades are a favorite among long-haul drivers. They feature an exclusive rubber compound that resists heat and ozone degradation, plus an asymmetrical spoiler that keeps the blade pressed firmly against the glass at highway speeds.
• Rain-X Latitude: (Premium) Known for applying a water-repelling coating directly onto the windshield as they wipe, these are fantastic for running through heavy rainstorms.
• Trico Force: (Mid-Range to Premium) Featuring a swept-wing spoiler, these blades are designed specifically to combat wind lift at high speeds, making them perfect for the massive windshield of a VNL.
• Michelin Stealth: (Mid-Range) A great hybrid blade that combines the anti-clogging benefits of a beam blade with the structural rigidity of a traditional frame blade.
• PIAA Si-Tech: (Premium) Made from high-quality silicone rather than traditional rubber, these blades often outlast standard replacements and leave a continuous hydrophobic layer on the glass.

Attachment style

The 2018 Volvo VNL utilizes a standard 9x3 J-hook attachment. This is one of the most common and universal wiper arm styles in the automotive and commercial trucking industries. You won't have to deal with complicated push-button or finicky side-pin adapters; practically any heavy-duty or standard 24-inch blade with a J-hook adapter will click right into place.

How to install

Swapping the blades on your VNL is a quick job that can be done at a rest stop or fuel island in just a few minutes.

1. Lift the wiper arm: Pull the heavy-duty wiper arm away from the windshield until it locks into its upright position.
2. Remove the old blade: Locate the small plastic tab where the blade meets the J-hook of the wiper arm. Press or push this tab, and slide the wiper blade downward (towards the base of the arm) to unhook it.
3. Position the new blade: Insert the hook of the wiper arm through the center opening of your new aftermarket or OEM blade.
4. Lock it in: Pull the blade upward tightly into the J-hook until you hear a firm click.
5. Lower gently: Carefully place the wiper arm back against the windshield. Never let it snap back, as the bare metal hook can easily crack the glass.

When to replace

For over-the-road trucks, wiper blades degrade much faster than they do on passenger cars. You should generally plan to replace your VNL’s wiper blades every 6 to 12 months. However, you should replace them immediately if you notice:

• Streaking or smearing: Leaving un-wiped bands of water right in your line of sight.
• Chattering: The blade skipping loudly across the glass rather than gliding smoothly.
• Torn rubber: Any visible splitting or separation of the squeegee edge.
