Truck Hardware Gatorback Black Plate Mud Flaps - Set

Upgrade your truck's protection with the Truck Hardware Gatorback Black Plate Mud Flap Set. Tailor-made to fit 2014-2018 GMC Sierra 1500, 2019 GMC Sierra 1500 Limited, and 2015-2019 GMC Sierra 2500 HD and 3500 HD (Single Rear Wheel), these mud flaps provide premium protection against road debris while adding a sleek, rugged look to your vehicle. Featuring black anodized aluminum plates, these mud flaps are designed for those who appreciate both form and function in their truck accessories.

Constructed from 1/2" thick heavy-duty virgin rubber, these mud flaps are built to withstand the toughest conditions, offering superior durability, flexibility, and resistance to cracking or fading. Virgin rubber ensures maximum performance, giving you mud flaps that can endure extreme weather conditions, rocks, and road grime, all while maintaining their integrity. The 12" wide flaps offer optimal tire coverage, keeping your truck cleaner for longer and reducing paint damage from kicked-up debris.

The Gatorback series is known for its exceptional quality and rugged design. The anodized black aluminum plate adds a modern, aggressive look to your truck without compromising functionality. The plates are meticulously crafted to match the high standards of Truck Hardware’s Gatorback line, ensuring your truck is protected while looking its best.

Key Features

  • Heavy-Duty Virgin Rubber Construction: Crafted from 1/2" thick virgin rubber, these mud flaps are incredibly durable, resisting cracking, fading, and wear. The high-quality rubber material provides excellent coverage and stability, even at highway speeds.
  • Black Anodized Aluminum Plates: Each flap features a 10 1/4" x 5" black anodized aluminum plate, adding a sleek and aggressive look to your truck. The plates are designed to maintain their appearance in harsh conditions, adding style without sacrificing toughness.
  • Full Tire Coverage: The front flaps offer 5" of tire coverage, while the rear flaps provide 7.5", protecting your truck from dirt, gravel, mud, and other debris that can cause damage.
  • Custom-Fit Rear Support Brackets: Included custom rear support brackets (GB756802) provide added stability, ensuring the mud flaps stay securely in place without excessive movement or wear.

Installation

Front Flap Installation: The front mud flaps are designed to fasten directly to the lip of the wheel well using self-tapping screws, with existing factory fasteners also usable if available. The installation is simple, requiring only basic tools. Be sure to leave at least 1/2" of clearance between the tire and wheel well to accommodate the flap thickness. These flaps install flush with the wheel well, ensuring compatibility with accessories like step bars, power boards, or side steps.

Rear Flap Installation: The rear mud flaps are secured using the included custom-fit rear support brackets and self-tapping screws. These brackets provide added stability, preventing the flaps from contacting the tires and minimizing movement during challenging driving conditions.

What's Included

  • (2) Front Mud Flaps - 12" x 23" Cut Style (GB1223CUTAA)
  • (2) Rear Mud Flaps - 12" x 23" Full Style (GB1223AA)
  • Custom Rear Support Brackets (GB756802)
  • Stainless Steel Self-Tapping Mounting Screws

Care & Maintenance

To keep your Gatorback Black Plate Mud Flaps looking their best:

  • Rubber Flaps: Clean regularly with mild soap and water to remove dirt, grime, and road salt.
  • Aluminum Plates: Wipe down with a non-abrasive cleaner to maintain the anodized finish.
  • Periodically inspect all mounting hardware to ensure it remains secure, 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 original owner for the lifetime of the product. 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 reprocessed, providing superior strength, flexibility, and resistance to environmental damage compared to recycled alternatives.
  • Self-Tapping Screws: Screws that create their own hole as they are driven into materials, making installation easier and more secure.
  • Anodized Aluminum: Aluminum that has been coated through an anodizing process to increase durability and resistance to corrosion, while also providing an attractive finish.

The Truck Hardware Gatorback Black Plate Mud Flaps offer an ideal combination of rugged protection, refined aesthetics, and high-quality materials. Featuring durable virgin rubber and black anodized aluminum plates, these mud flaps are designed to provide outstanding defense against road debris while adding a sleek, modern look to your truck. Trust Gatorback for quality craftsmanship and dependable performance, ensuring your truck remains protected and looking great on any adventure.
