2016 GMC Sierra 2500HD Wiper Blade Sizes & Replacement Guide

Ensuring your 2016 GMC Sierra 2500HD has fresh, properly functioning windshield wiper blades is essential for maintaining visibility and safety during heavy rain, snow, or sleet. A heavy-duty truck demands heavy-duty performance, and knowing the exact sizes and attachment types for your vehicle will save you time at the parts counter.

Below is a comprehensive guide to the correct wiper blade sizes, premium aftermarket upgrades, and replacement procedures for your 2016 GMC Sierra 2500HD.

Quick reference

Here is the essential sizing and fitment data for your 2016 GMC Sierra 2500HD. Note that because the Sierra is a pickup truck, it does not come equipped with a rear window wiper.

Note: Always verify exact OEM part numbers with your local GM parts department using your VIN, as supersessions frequently occur.

Best aftermarket replacements

If you prefer to upgrade from factory wiper blades, the aftermarket offers a variety of premium beam-style blades that excel in clearing mud, bugs, and ice. Here are the top aftermarket replacements for the Sierra 2500HD:

• Bosch ICON: (Premium tier, ~$25-$35 each) Known for exceptional durability and exclusive rubber compounds, the ICON is an industry standard for beam-blade performance.
• Rain-X Latitude: (Mid-to-high tier, ~$20-$30 each) Features a water-repelling coating that transfers to your windshield, forcing water to bead up and roll off at highway speeds.
• Trico Force: (Mid-tier, ~$20-$25 each) Designed with a swept-wing spoiler to slice through heavy crosswinds, making it ideal for large, flat truck windshields.
• Michelin Stealth: (Mid-tier, ~$15-$25 each) A robust hybrid blade combining the flexibility of a beam blade with the structural integrity of a conventional frame.
• PIAA Si-Tech: (Premium tier, ~$30-$40 each) Made with silicone rubber that lasts twice as long as traditional rubber, actively treating the glass with silicone every time it wipes.

Attachment style

The 2016 GMC Sierra 2500HD uses a Push-button attachment style (often referred to as a PTB or Push-Type Button arm). Unlike the older, more common J-hook design, this modern arm connection provides a highly secure fit and a much lower aerodynamic profile. When purchasing aftermarket blades, verify that the packaging includes the specific adapter for the push-button arm.

How to install

Replacing the push-button wiper blades on your Sierra 2500HD is a straightforward process that requires no tools:

1. Lift the wiper arm: Carefully lift the wiper arm away from the windshield until it locks into its upright position. Hold the arm securely so it doesn't snap back and crack the glass.
2. Remove the old blade: Locate the small square button where the blade meets the wiper arm. Press this button down firmly, and simultaneously pull the wiper blade straight out, away from the base of the arm.
3. Prep the new blade: If using an aftermarket blade, install the correct push-button adapter provided in the packaging according to the manufacturer's instructions.
4. Install the new blade: Slide the new blade into the wiper arm until you hear a distinct "click," indicating the button has securely locked into the hole on the arm.
5. Test: Gently lower the arm back to the windshield. Turn on the ignition and activate the wipers with wiper fluid to ensure they are properly seated and clearing the glass.

When to replace

For optimal safety, you should replace your wiper blades every 6 to 12 months. Environmental factors like UV rays, road salt, and freezing temperatures degrade the rubber over time. You should replace your blades immediately if you notice:

• Streaking or smearing across your line of sight.
• Chattering or squeaking as the blade drags across the wet glass.
• Splitting or tearing of the rubber squeegee edge.
• Unwiped patches or missed sections on the windshield.
