Truck Hardware Gatorback "Denali" Logo Mud Flaps - Set

Add a touch of luxury and rugged protection to your GMC Sierra with the premium Truck Hardware Gatorback "Denali" Logo Mud Flap Set. Specifically crafted for 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 are designed to provide both exceptional style and high-grade protection for your truck. Whether you're tackling rugged terrains or cruising the highway, these mud flaps keep your vehicle shielded from road debris, preserving its finish while showing off your Denali pride.

Manufactured from 1/2" thick, heavy-duty virgin rubber, these 12" wide mud flaps offer superior durability and flexibility. Virgin rubber is highly resilient, providing better resistance to cracking, fading, and warping compared to recycled alternatives. The weight of these mud flaps ensures they stay securely in place, reducing "sailing" at high speeds or in windy conditions. The flaps are adorned with an officially licensed Denali logo, die-stamped onto a premium stainless steel plate with a hand-applied vinyl overlay, adding a sleek and upscale touch that complements the Denali's luxury styling.

The Truck Hardware Gatorback series is renowned for its industry-leading quality in heavy-duty mud flaps. This set includes both front and rear mud flaps, custom-fit for your GMC Sierra, ensuring an exact fit with the use of custom rear support brackets and factory-aligned fasteners. The front mud flaps provide 5" of tire coverage from the bottom of the fender to the bottom of the flap, while the rear flaps offer 7.5" of coverage—giving your truck comprehensive protection from rocks, mud, gravel, and other road debris that could cause costly damage to your paint or body.

Key Features

  • Heavy-Duty Virgin Rubber Construction: Made from 1/2" thick premium virgin rubber, these mud flaps offer outstanding durability and are highly resistant to cracking, fading, and warping. Virgin rubber provides superior strength and flexibility, ensuring that your mud flaps remain intact and effective for years to come.
  • Custom-Fit Design: Designed specifically for 2014-2019 GMC Sierra models. The set includes custom-fit rear support brackets (GB756802) that add stability and prevent unwanted movement, even in challenging driving conditions.
  • Officially Licensed Denali Logo: The stainless steel plates feature the iconic Denali logo, die-stamped for precision and finished with a hand-applied vinyl overlay. This adds a bold, premium appearance that complements the distinctive styling of your truck.
  • Comprehensive Tire Coverage: The front mud flaps offer 5" of tire coverage, while the rear provide 7.5" of coverage. This ensures superior protection from road debris, helping to maintain the pristine condition of your truck's exterior.

Installation

Front Flap Installation: The front mud flaps attach directly to the lip of the wheel well using self-tapping screws, with the option to use existing factory fasteners if available. Installation is straightforward, requiring only basic tools for a hassle-free experience. Ensure there is at least 1/2" of clearance between the tires and the wheel well to accommodate the flap thickness. The front flaps install flush with the wheel well, allowing seamless integration with other accessories like step bars, power boards, or side steps.

Rear Flap Installation: The rear mud flaps are secured using custom-fit rear support brackets and self-tapping screws, holding them tightly against the wheel well to minimize movement and prevent the flaps from flapping into the tires. This secure installation helps maintain the integrity of the mud flaps, even in tough driving environments.

What's Included

  • (2) Front Mud Flaps - 12" x 23" (GB1223CUTD)
  • (2) Rear Mud Flaps - 12" x 23" (GB1223D)
  • 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 maintain the polished finish.
  • Inspect mounting hardware periodically to ensure it remains secure, especially after off-road use or exposure to harsh weather conditions.

Manufacturer Warranty

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

Terms

  • Virgin Rubber: Rubber that has not been recycled or reprocessed, offering superior durability, flexibility, and resistance to wear compared to recycled rubber.
  • Self-Tapping Screws: Screws designed to drill their own hole as they are driven into materials such as metal or plastic, simplifying the installation process.
  • Die-Stamped: A process where the logo is stamped into the metal 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 "Denali" Logo Mud Flaps are the perfect combination of luxury, rugged durability, and effective protection for your GMC Sierra. Featuring premium virgin rubber construction, iconic Denali branding, and comprehensive coverage, these mud flaps are designed to enhance your truck's style while defending it against the elements. Choose Gatorback for unmatched quality and protection, and elevate your truck's look and performance.

Questions & answers

3 questions

Question: Will these mud flaps fit my 2019 Denali?

Asked by J.R. 10/30/2018

Answer from the SharpTruck team: These will fit the 2019 2500 HD and 3500 HD as well as the 1500 Limited Denali. If it is the new body style they will not. Truck Hardware is working getting the custom fit flaps for the new truck finished up.

Question: Will these mud flaps fit my 2018 Yukon Denali?

Asked by Andrew Gooch 2/6/2021

Answer from the SharpTruck team: They will not the Yukon. The wheel well of the Yukon is mostly plastic with the rear bumper. That is not strong enough to supper the weight of the mud flap.

On the front there is not enough clearance between the tire and the inside of the wheel well to allow these flaps to be installed.
