There isn’t a single universal size for Freightliner windshield wipers—the correct length depends on the specific model and year of the truck.
In practice, Freightliner uses several common blade lengths across its lineup (Cascadia, M2, FL-Series, and others). To be sure you buy the right size, consult the vehicle’s manual, inspect the current blades, or use a VIN-based parts lookup from Freightliner or an authorized dealer.
How to determine the right size
Follow these steps to identify the correct wiper blade sizes for your Freightliner truck.
- Inspect the current blades for size markings on the blade or frame, which often indicate the length.
- Look up replacement sizes using your Freightliner model and year in the OEM parts catalog or an authorized dealer portal; you can often search by VIN to pull exact specifications.
- If catalogs aren’t accessible, measure the blades on the truck by removing them and measuring from the pivot point to the tip on each side.
- When in doubt, contact a Freightliner dealer or parts retailer and provide your VIN or exact model/year to get the correct pair.
By confirming the blade length with one of these methods, you ensure you buy the correct size for reliable wiping and to protect the windshield seal and mechanism.
Model-specific notes
Cascadia
Wiper blade sizes for Cascadia models have varied with generation and options. Always verify with the VIN or by measuring the blades currently installed to ensure a proper fit.
M2 and FL-Series
For M2 and FL-Series trucks, blade lengths can differ by year and cab configuration. Use VIN-based lookup or the truck’s manual to confirm the exact replacement sizes before purchasing.
Summary
Freightliner windshield wiper sizes are model- and year-specific, not universal. To find the correct size, check the current blades, consult the vehicle manual, or use a VIN-based parts lookup through Freightliner or an authorized dealer. If you cannot access catalogs, measure the existing blades or seek assistance from a dealer to ensure a proper fit and optimal windshield performance.
