2023 Freightliner M2 106 — Wiper Blade Sizes

Quick reference

Note: Most 2023 M2 106 trucks use 26-inch beam blades on both front positions. Some vocational upfits may use different arms; verify on-vehicle before purchase.

Best aftermarket replacements

These beam-style blades perform well on medium-duty trucks and are widely available. Choose the 26-inch size for both driver and passenger sides.

• Bosch ICON (premium): Excellent all-weather wipe and longevity; typically the priciest.
• Rain-X Latitude (upper mid-tier): Strong wet-weather performance and easy install.
• Trico Force (mid-tier): Aerodynamic beam blade that resists lift at highway speeds.
• Michelin Stealth (mid-tier): Hybrid beam design with good coverage and durability.
• PIAA Si-Tech (premium): Silicone rubber inserts lay down a water-repellent film for long-term clarity.

Tip: Many of these lines include multiple connector adapters in the package to fit common heavy-duty J-hook arms.

Attachment style

• Primary: J-hook arm. Most M2 106 trucks use a standard J-hook connection. Heavy-duty applications may have either a 9x3 mm (3/8-inch) hook or a larger 12 mm hook. The listed blades include adapters for both in many cases.
• Less common variants: Some upfitted units may use side pin or bayonet connectors. If your arm does not curve into a hook, inspect the end for a straight "bayonet" tab or a small transverse pin—choose an adapter or blade that matches.

If you’re unsure which you have, snap a quick photo of the arm end and compare to the adapter illustrations on the blade packaging.

How to install

1. Park the truck on level ground, key off, and set the parking brake. If possible, place the wipers in service position or lift the arms away from the glass.
2. Protect the windshield with a towel in case the arm springs back.
3. Remove the old blade:
   • J-hook: Press the release tab on the blade, slide the blade down toward the arm’s curve, then unhook it.
   • Side pin or bayonet: Depress the locking tab or screw (if used), then slide the blade straight off the arm.
4. Select the correct adapter for your arm type from the new blade kit (most include J-hook, with optional side pin/bayonet adapters).
5. Install the new blade onto the arm until it clicks/locks. Tug gently to confirm it’s secure.
6. Lower the arm carefully to the glass.
7. Test on washer fluid to confirm full, streak-free contact across the sweep.

Unusual attachment? Refer to the blade’s specific adapter instructions—some heavy-duty arms use a secondary locking clip or screw.

When to replace

• Interval: Every 6–12 months in typical service; sooner for trucks that live outdoors or see extreme heat, cold, dust, or road salt.
• Symptoms it’s time: Streaking, chattering/skipping, squeaking, cracked or split rubber edges, or missed areas at the ends of the sweep.
• Fleet tip: Rotate replacement on a schedule before the rainy/snow season to reduce downtime.
