Truck Hardware Gatorback Rubber Mud Flaps - Set

Protect your truck with the Truck Hardware Gatorback Rubber Mud Flap Set. Designed 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 superior protection while maintaining a sleek, rugged look. Featuring 12" wide heavy-duty rubber construction, these mud flaps are built to keep your truck cleaner for longer while preventing road debris from causing damage to your paint or bodywork.

Constructed from 1/2" thick virgin rubber, these mud flaps offer unmatched durability, flexibility, and resistance to cracking, fading, and warping. Virgin rubber provides the toughness required to withstand harsh weather conditions, rocks, mud, and other road debris. The custom-fit design ensures a perfect fit, with front mud flaps providing 5" of tire coverage and rear mud flaps offering 7.5" of coverage, keeping your truck and those around you protected.

The Gatorback series from Truck Hardware is synonymous with quality craftsmanship and robust protection. Each mud flap in this set includes a sleek, understated design, perfect for those who appreciate a clean, classic look. With included custom rear support brackets (GB756802), these mud flaps remain securely fastened, providing reliable performance even in the most demanding conditions.

Key Features

  • Heavy-Duty Virgin Rubber Construction: Made from 1/2" thick virgin rubber, these mud flaps are highly durable, offering superior resistance to cracking, fading, and other forms of wear. The high-quality rubber material keeps the flaps steady, even at highway speeds.
  • Full Tire Coverage: The front flaps provide 5" of tire coverage, while the rear flaps offer 7.5", ensuring your truck stays protected from dirt, gravel, mud, and other road debris.
  • Custom-Fit Rear Support Brackets: Custom rear support brackets (GB756802) are included to ensure added stability, preventing unwanted movement and maintaining a secure fit for the mud flaps.
  • Simple, Sleek Design: With a minimalistic look, these mud flaps add a clean, rugged aesthetic to your truck, perfect for anyone looking for practical protection without excessive branding.

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 straightforward and requires 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, minimizing movement and preventing the flaps from contacting the tires, even in challenging driving conditions.

What's Included

  • (2) Front Mud Flaps - 12" x 23" Cut Style (GB1223CUTBK)
  • (2) Rear Mud Flaps - 12" x 23" Full Style (GB1223BK)
  • Custom Rear Support Brackets (GB756802)
  • Stainless Steel Self-Tapping Mounting Screws

Care & Maintenance

To keep your Gatorback Rubber Mud Flaps looking their best:

  • Rubber Flaps: Clean regularly with mild soap and water to remove dirt, grime, and road salt.
  • 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.
  • UV Resistant: Treated rubber to resist damage from ultraviolet (UV) light, preventing cracking or fading over time.

The Truck Hardware Gatorback Rubber Mud Flaps are the perfect combination of rugged durability, practical protection, and sleek style. Crafted with high-quality virgin rubber and custom-fit support brackets, these mud flaps are designed to protect your truck and enhance its look. Trust Gatorback for exceptional quality, fit, and performance, ensuring your truck stays protected and looking great wherever your adventures take you.
