Best Aftermarket Replacements
The 2020 Chevrolet Silverado 1500 uses a 22-inch blade on both the driver and passenger sides. Here are some of the best aftermarket replacement options available, listed by approximate price tier:

Attachment Style
The 2020 Silverado 1500 uses a standard J-hook wiper arm attachment. This is the most common type of wiper arm, making it easy to find a wide variety of replacement blades that will fit without special adapters.
How to Install
Replacing the wiper blades is a simple DIY job that usually takes less than 15 minutes.
- Lift the wiper arm away from the windshield until it locks in the upright position.
- Locate the small tab on the underside of the wiper blade connector, where it meets the J-hook of the wiper arm.
- Press the tab and push the blade down to release it from the hook. It may require a little wiggling.
- Slide the new blade onto the J-hook until it clicks securely into place.
- Gently lower the wiper arm back onto the windshield.
Note: Always read the specific instructions included with your new blades, as some may have slightly different locking mechanisms.
When to Replace
Wiper blades are a safety item that should be replaced every 6 to 12 months. You should replace them sooner if you notice any of the following signs of wear:
- Streaking: Leaving lines or streaks of water on the windshield.
- Chattering: The blade skipping or vibrating across the glass.
- Squeaking: A loud noise as the blade moves.
- Cracked or torn rubber: Visible damage to the blade element.
