What is the wiper blade size for 1981 Chevy Suburban?

There's no single wiper blade size for a 1981 Chevy Suburban. The size depends on the specific trim level and whether it's a 2-door or 4-door model. The best way to determine the correct size is to:

1. Check your owner's manual: This is the most reliable source. The manual should specify the correct wiper blade sizes for your specific Suburban.

2. Look at the existing wiper blades: The size is usually printed on the blade itself.

3. Measure the existing blades: If the blades are still in place and legible, carefully measure the length of each blade.

4. Use an online wiper blade finder: Many websites allow you to enter your vehicle's year, make, and model to find compatible wiper blade sizes. However, double-check the results against your owner's manual or the blades themselves.
