Truck Hardware Gatorback Black Wrap "Duramax" Logo Mud Flaps - Set

Take your GMC Sierra to the next level with the premium Truck Hardware Gatorback Black Wrap "Duramax" Logo Mud Flap Set. Specially crafted for 2015-2019 GMC Sierra 2500 HD and 3500 HD (Single Rear Wheel), these mud flaps offer superior protection and a bold, distinctive look. Featuring the iconic Duramax logo against a black background, these mud flaps give your truck an aggressive yet refined appearance while keeping it protected from harsh road elements.

Constructed from 1/2" thick heavy-duty virgin rubber, these mud flaps are built to withstand the toughest conditions while maintaining their flexibility and durability. Virgin rubber is the highest quality rubber available, providing exceptional resilience against cracking, fading, and warping, which makes it perfect for withstanding extreme temperatures and constant road debris. The 12" wide flaps offer full tire coverage to protect your truck from mud, rocks, salt, and other road hazards that could damage its paint and body.

The Gatorback series is known for its premium quality and rugged construction, ensuring you get the very best in heavy-duty mud flaps. Each mud flap in this set features the officially licensed Duramax logo, die-stamped onto a high-quality stainless steel plate with a hand-applied vinyl overlay, ensuring a polished and professional look. The plates measure 10 1/4" x 5", adding a stylish, high-contrast accent to your truck's exterior.

Key Features

  • Heavy-Duty Virgin Rubber Construction: Made from 1/2" thick virgin rubber, these mud flaps offer superior strength, flexibility, and resistance to cracking or fading compared to recycled alternatives. The high-quality rubber keeps the flaps in place without flapping, even at highway speeds.
  • Duramax Branding: Officially licensed Duramax logo die-stamped onto stainless steel plates with a black wrap background. The sleek design adds a bold, personalized touch to your truck, showcasing the power behind your vehicle.
  • Full Tire Coverage: The front flaps provide 9" of tire coverage, while the rear offer 7.5", ensuring that your truck is fully protected from dirt, mud, gravel, and other debris.
  • Custom-Fit Rear Support Brackets: The set includes custom rear support brackets (GB756802) for added stability, preventing unwanted movement and ensuring a secure fit for the mud flaps in any driving condition.

Installation

Front Flap Installation: The front mud flaps are designed to fasten directly to the lip of the wheel well using stainless steel self-tapping screws, and existing factory fasteners can also be used if available. The installation is simple and requires only basic tools, making it a straightforward task for any truck owner. Ensure at least 1/2" of clearance between the tire and wheel well to accommodate the flap thickness. The front flaps install flush with the wheel well, allowing seamless integration with accessories like step bars or power boards.

Rear Flap Installation: The rear mud flaps are installed using custom-fit rear support brackets and self-tapping screws. These brackets ensure that the mud flaps remain securely mounted, minimizing movement and preventing contact with the tires. This secure installation ensures that your truck is well-protected, even during off-road driving or in tough weather conditions.

What's Included

  • (2) Front Mud Flaps - 12" x 23" Cut Style (GB1223CUTDXW2)
  • (2) Rear Mud Flaps - 12" x 23" Full Style (GB1223DXW2)
  • Custom Rear Support Brackets (GB756802)
  • Stainless Steel Self-Tapping Mounting Screws

Care & Maintenance

To maintain the performance and appearance of your Gatorback mud flaps:

  • Rubber Flaps: Clean regularly with mild soap and water to remove dirt, grime, and road salt.
  • Stainless Steel Plates: Wipe down with a non-abrasive cleaner to keep the polished finish looking its best.
  • Periodically inspect all mounting hardware to ensure it remains tight, especially after off-road use or exposure to harsh conditions.

Manufacturer Warranty

Gatorback mud flaps are backed by a Limited Lifetime Warranty. This warranty covers the replacement of rubber components (e.g., tear-offs) for the lifetime of the product for the original owner. It does not cover damage caused by misuse, abuse, or normal wear and tear of brackets, plates, or mounting hardware.

Terms

  • Virgin Rubber: Rubber that has not been recycled or processed, offering superior strength, flexibility, and resistance to environmental damage compared to recycled rubber.
  • Self-Tapping Screws: Screws that create their own hole as they are driven into materials, simplifying the installation process.
  • Die-Stamped: A process where the logo is imprinted onto the stainless steel plate, ensuring a precise, consistent, and high-quality finish.
  • UV Resistant: The rubber material is treated to resist damage from ultraviolet (UV) light, preventing cracking or fading over time.

The Truck Hardware Gatorback Black Wrap "Duramax" Logo Mud Flaps combine rugged durability with sleek styling, providing the ultimate protection for your GMC Sierra. Crafted with heavy-duty virgin rubber, officially licensed Duramax branding, and custom-fit support brackets, these mud flaps are designed to protect your truck while enhancing its visual appeal. Trust Gatorback to deliver the best in quality, fit, and performance, ensuring your truck stays looking great and ready for any adventure.
