2020 Volvo VNL — Wiper Blade Sizes & Replacements

Quick reference

*Most 2020 Volvo VNL tractors use a 12 mm side-pin arm. Some fleets may have retrofit arms; always verify on your truck before purchasing.

Best aftermarket replacements

Below are popular beam-style blades that perform well on Class 8 tractors when ordered in 26-inch length and with the correct 12 mm side-pin adapter kit:

• Bosch ICON (premium): Excellent all-weather wipe and longevity. Expect roughly $28–40 per blade. Ensure the package includes a 12 mm side-pin adapter or use Bosch HD/commercial adapters.
• Rain-X Latitude Water Repellency (upper mid-range): Good performance in rain and light snow, ~$22–30 each. Confirm side-pin compatibility.
• Trico Force (upper mid-range): Aerodynamic beam blade that handles highway speeds well, ~$20–30 each. Trico also offers dedicated HD variants with side-pin hardware.
• Michelin Stealth Ultra (mid-range): Hybrid beam design, ~$18–28 each. Verify adapter fit for 12 mm side pin.
• PIAA Si-Tech (premium): Silicone rubber for long life and water beading, ~$30–45 each; adapter check required.

Note: Some passenger-car blades only include J-hook/8–9 mm adapters. For the VNL’s common 12 mm side-pin arms, select SKUs labeled for “side pin” or “commercial/HD” applications, or purchase the brand’s side-pin adapter kit separately.

Attachment style

• Common on 2020 VNL: Side pin (12 mm). The arm has a round pin that inserts into the blade’s saddle, retained by a spring clip.
• Less common variations you may encounter (retrofit/fleet-specific):
  • J-hook (9x3): Requires standard hook adapter.
  • Bayonet or 7 mm side pin: Seen on some older or modified arms.

Because commercial fleets sometimes replace arms, verify your truck’s attachment before ordering. A quick photo of the arm end compared to the adapter chart on the blade box can prevent returns.

How to install

1. Park safely and key off. Tip the wiper arms away from the glass if spring tension allows.
2. Remove old blade:
   • Side pin: Depress the spring tab on the blade saddle and slide the blade off the arm’s pin.
   • J-hook: Press the locking tab, rotate the blade 90°, and slide downward to unhook.
   • Push-button/bayonet: Press the release button or tab and pull straight off.
3. Prep the new blade: Fit the correct adapter for your arm style (12 mm side pin for most VNLs). Ensure it clicks/locks fully.
4. Install: Align the adapter with the arm, slide onto the pin until the spring clip snaps. Tug lightly to confirm retention.
5. Test: Lower the arm carefully to avoid glass impact. Cycle washers/wipers to verify secure attachment and clean wipe.

Tip: If your arm won’t stay lifted, place a folded towel on the cowl to protect the glass while working.

When to replace

• Interval: Every 6–12 months for daily-driven tractors; sooner in harsh weather or high-mileage fleet use.
• Signs it’s time: Streaking, chattering, missed areas, split or torn rubber, or blade chatter at highway speeds.
• Pro move: Clean the rubber with washer fluid or isopropyl alcohol during fuel stops to extend life.
