Front wiper blades for most 2020 Silverado pickups are 22 inches on both the driver and passenger sides, with a 14-inch rear blade if your cab configuration includes a rear window wiper. Exact sizes can vary by cab and trim, so verify for your specific truck.
Front wiper blade sizes
The front blades on a 2020 Silverado are designed to cover the primary swept area of the windshield, and the two sides are typically matched in length for balanced performance.
- Driver's side blade: 22 inches
- Passenger side blade: 22 inches
For most 2020 Silverado models, the front wiper blades are 22 inches long on both sides. If your vehicle has an unusual configuration or a non-standard trim, sizes may differ slightly.
Rear wiper blade size and variations
Whether a rear window wiper is present depends on cab style and trim. If your Silverado is equipped with a rear wiper, the blade is typically smaller than the front blades.
- Rear blade: 14 inches (if the rear wiper exists on your model)
Note that several Silverado variants—especially certain cab configurations—may omit the rear wiper entirely. Always confirm with the owner's manual or by inspecting the current blade.
How to confirm the exact size for your truck
To be certain of the blade lengths for your 2020 Silverado, check one or more of these sources:
- Your owner’s manual wiper blade section
- GM OEM parts catalog or a Chevrolet dealer parts counter
- The current blades on your truck (measure the length end-to-end or bring the blade to a parts store for a precise match)
In practice, many owners simply order by make/model/year and cab style, or replace blades with the exact OEM specification to ensure a proper fit.
Summary
For a typical 2020 Silverado, plan for 22-inch front wiper blades on both sides and a 14-inch rear blade if your configuration has a rear window wiper. Always verify against your specific cab and trim, or consult the owner’s manual or a Chevrolet parts specialist to confirm exact sizes.
