2019 GMC Sierra 1500 Wiper Blade Sizes & Replacement Guide

Keeping your line of sight clear is critical when driving a full-size truck. If you are noticing streaks, smears, or missed spots on the windshield of your 2019 GMC Sierra 1500, it is likely time to replace the wiper blades. Finding the exact fit for your vehicle is simple once you know the correct lengths and attachment style.

Below is your complete guide to replacing the wiper blades on a 2019 GMC Sierra 1500.

Quick reference

For the 2019 GMC Sierra 1500, both the driver and passenger sides use the exact same size wiper blade. Because it is a pickup truck, there is no rear wiper assembly.

Note: Always double-check your current blades, as attachment styles can sometimes vary based on early/late year production dates or trim levels.

Best aftermarket replacements

If you prefer to upgrade from standard factory wipers, the aftermarket offers several premium beam-style and silicone options that perform exceptionally well on the large windshield of the Sierra 1500.

• Bosch ICON: (Premium Price Tier) Widely considered the gold standard for beam blades. They offer excellent pressure distribution and boast a long lifespan thanks to their proprietary rubber compound.
• Rain-X Latitude: (Mid-to-High Price Tier) A fantastic choice if you want water-repelling functionality. These beam blades apply a water-beading coating to the glass as they wipe.
• Trico Force: (Mid Price Tier) Specifically designed with a swept-wing spoiler to resist wind lift at highway speeds, making them ideal for full-size trucks like the Sierra.
• Michelin Stealth: (Mid Price Tier) A hybrid blade that combines the anti-clogging benefits of a beam blade with the structural support of a traditional frame.
• PIAA Si-Tech: (Premium Price Tier) Made from advanced silicone rubber, these blades resist ozone and UV breakdown much better than natural rubber, lasting up to twice as long.

Attachment style

The 2019 GMC Sierra 1500 utilizes a Push-button attachment style (often referred to as a narrow push-button or PTB). Unlike the older, more common J-hook design, this modern mechanism locks the blade directly into the top of the wiper arm. It is incredibly secure and actually makes replacing the blades faster once you know how the release mechanism works.

How to install

Replacing push-button wiper blades on your Sierra is a tool-free process that takes only a few minutes.

1. Lift the wiper arm: Carefully lift the wiper arm away from the windshield. Be sure to hold onto it firmly; if it snaps back against the glass without a blade attached, it can crack your windshield.
2. Remove the old blade: Locate the small square button where the wiper arm meets the blade. Press this button down firmly, and while holding it, pull the wiper blade straight out and away from the wiper arm.
3. Prepare the new blade: If you purchased aftermarket blades, ensure you have the correct push-button adapter clicked into place (consult the instructions inside the blade packaging).
4. Install the new blade: Slide the new blade into the wiper arm until you hear a distinct "click." Give the blade a gentle tug to ensure it is securely locked in place.
5. Lower the arm: Gently lower the wiper arm back onto the windshield. Repeat for the passenger side.

When to replace

For optimal visibility and safety, you should replace your wiper blades every 6 to 12 months. The rubber naturally degrades from exposure to UV rays, extreme temperatures, and road grime.

You'll know it's time for a new set if you experience:

• Streaking or smearing across your line of sight.
• Chattering or squeaking as the blades skip across the glass.
• Unwiped sections left behind, which usually indicates the internal tension spring of the blade has worn out.
• Cracked or torn rubber visible upon physical inspection.
