The front wiper blades on the 2020 Freightliner Cascadia are typically 28 inches on both the driver and passenger sides, while the rear blade is typically 12 inches. These sizes cover most units in this model year, but there can be variations based on trim or aftermarket parts.
The Cascadia is a heavy-duty truck with a large windshield, so standard replacement blades are commonly 28 inches for the front and 12 inches for the rear. Always verify with your owner’s manual or by measuring the current blades to account for any exceptions or aftermarket configurations.
Front wiper blade sizes
Here are the standard front blade lengths used on the 2020 Cascadia. Most owners opt for matching lengths on both sides for even coverage.
- Driver-side: 28 inches
- Passenger-side: 28 inches
In practice, these 28-inch blades fit the majority of Cascadia front assemblies. If you notice reduced coverage or interference, double-check the blade length and compatibility with your specific windshield and wiper arms.
Rear wiper blade size
The rear window on most 2020 Cascadia models uses a 12-inch blade.
- Rear: 12 inches
If your truck has a different rear configuration due to aftermarket parts or a unique cab setup, verify the length by measuring the existing blade or consulting the manual or vendor specs.
How to verify the right size for your Cascadia
Use these steps to confirm you’re purchasing the correct blades for your specific cab:
- Check the owner’s manual for the recommended blade sizes.
- Measure the length of the current blades from tip to tip when removed from the arm.
- Consult the parts compatibility guide when buying aftermarket replacements to ensure a proper fit.
Following these steps helps ensure you get blades that fit securely and provide optimal wipe coverage for safe operation.
Summary
For the 2020 Cascadia, the typical configuration is front blades of 28 inches on both sides and a 12-inch rear blade. Always verify with your manual or by measuring the current blades, as some trims or aftermarket setups can differ.
