The front wiper blades on a 2013 GMC Sierra 1500 are typically 22 inches on both the driver and passenger sides. A rear wiper is not standard on most configurations, but if your truck does have one, it will be a smaller blade. The exact size can vary by cab configuration, so it's best to verify for your specific vehicle.
In more detail, wiper blade lengths can differ based on whether your Sierra 1500 has a Regular Cab, Extended Cab, or Crew Cab, and whether your model includes a rear window wiper. Use the owner's manual, inspect the current blades, or perform a VIN-based parts lookup to confirm the precise lengths for your exact build. Below is a practical guide to common sizes and verification steps.
Front wiper blade sizes
Before listing the sizes, note that these reflect the typical front blade lengths used on most 2013 Sierra 1500s. Your exact cab/trim may differ, so verify if needed.
- Driver-side blade: 22 inches
- Passenger-side blade: 22 inches
Conclusion: For most 2013 Sierra 1500 models, you will use two 22-inch blades for the front. If your vehicle uses different lengths, check the manual or measure the blade mounting to confirm exact sizes.
Rear wiper blade (if equipped)
Not all 2013 Sierra 1500 configurations include a rear window wiper. If yours does, the rear blade is smaller than the front and typically falls in the 12–14 inch range, depending on the cab and tailgate design. Always verify with the manual or a parts lookup for your specific configuration.
- Rear blade (if equipped): 12–14 inches, varies by cab/trim
Conclusion: If your Sierra 1500 has a rear wiper, plan for a blade in the 12–14 inch range, and confirm the exact size for your build before purchasing.
How to verify the exact size for your truck
Use these quick methods to confirm the correct wiper blade lengths for your exact 2013 Sierra 1500 configuration:
- Check the owner’s manual or the wiper blade section for blade lengths by model/trim.
- Inspect the current blades and measure from tip to tip, noting the mounting style.
- Use a VIN-based parts lookup at an auto parts store or GM’s official parts site to pull exact sizes for your vehicle’s cab configuration.
Conclusion: Verifying through the official manual, current blades, or a VIN-based parts lookup ensures you buy the correct lengths for your specific Sierra 1500 build.
Summary
For most 2013 GMC Sierra 1500 trucks, the standard front wiper blades are 22 inches on both sides, with a rear blade only if your particular configuration includes a rear window wiper (typically 12–14 inches). Cab configuration and trim can affect exact sizes, so always verify via the manual, current blades, or a VIN-based parts lookup before purchasing replacements.
