The typical setup for a 2015 Chevy Silverado is 22-inch blades on both front sides, with a 12-inch blade for the rear window if the model is equipped with one.
Sizes can vary by cab configuration and market, so it’s best to verify the exact blade size for your truck by checking the owner's manual or the blade packaging, or by measuring the blade yourself.
Front windshield wipers: sizes
Note: The following sizes apply to most 2015 Silverado configurations. Some trims or aftermarket replacements may use different lengths, so always double-check before purchasing replacements.
- Driver-side blade: 22 inches
- Passenger-side blade: 22 inches
In practice, front blades on the 2015 Silverado are commonly 22 inches long on both sides. Always confirm by checking the blade packaging or your owner’s manual if you’re unsure.
Rear wiper blade: if equipped
Note: Some 2015 Silverado models with certain cab styles or market specifications include a rear window wiper. If yours has one, the blade is typically shorter than the front blades.
- Rear blade: 12 inches
If your Silverado does not have a rear wiper, you can skip this section. For rear-blade replacement, verify the length on the old blade or consult the manual or parts diagram for your specific vehicle.
How to verify the correct size
Check the owner's manual or parts diagram
The manual or a factory parts diagram will list the exact blade sizes for your year and cab configuration, ensuring you buy the correct replacement.
Inspect or measure the existing blades
Look for size markings on the blade itself or on the packaging. If replacing, remove the blade and compare its length against a ruler or tape measure to confirm the correct size.
Summary
For most 2015 Chevy Silverado models, the front windshield wipers use two 22-inch blades (driver and passenger), with a rear blade of about 12 inches if your model is equipped with a rear wiper. Always verify against your specific cab configuration and manual, as sizes can vary by market and trim.
