Truck Hardware Gatorback Black Wrap "GMC" Logo Dually Mud Flaps - Set

Show your GMC pride while protecting your truck with the Truck Hardware Gatorback Black Wrap "GMC" Logo Dually Mud Flaps. Specifically designed to fit 2015-2019 GMC Sierra 3500 HD (Dually Rear Wheel) models, these mud flaps combine rugged functionality with the sleek aesthetic of the iconic GMC logo set against a black wrap background. Built to withstand the toughest road conditions, these mud flaps provide excellent protection for your truck's finish while adding a refined, premium look.

Constructed from 1/2" thick premium virgin rubber, the Gatorback Black Wrap "GMC" Dually Mud Flaps are engineered to endure challenging environments while offering superior resilience and flexibility. Each rear flap weighs 10 pounds, ensuring they stay securely in place without 'sailing' or shifting, even at high speeds. With extensive tire coverage—5 inches for the front and 9.5 inches for the rear—these mud flaps protect your truck from rocks, mud, and other road debris.

The officially licensed GMC logo is die-stamped into a stainless steel plate with a hand-applied black vinyl overlay, guaranteeing a perfect, high-quality finish. The stainless plate measures 10 1/4" x 5" on the front and an impressive 17 1/4" x 5" on the rear, giving your truck a polished and distinctive look.

Installation

Front Flap Installation: The front mud flaps fasten directly to the lip of the wheel well using self-tapping screws, and existing factory fasteners can also be used if available. Installation is straightforward and requires only basic tools. Be sure to allow at least 1/2" of clearance between the tire and the wheel well to accommodate the flap's thickness. The front flaps install flush to the wheel well, allowing for seamless integration with accessories like step bars, power boards, or side steps.

Rear Flap Installation: The rear mud flaps come with custom-fit Gatorback dually mounting brackets, which are essential for ensuring a secure and stable fit. These galvanized steel brackets provide a strong mounting point, keeping the heavy-duty flaps firmly in place, even under challenging conditions. The rear brackets utilize existing factory holes, eliminating the need for drilling into the truck body, although drilling through the mud flaps themselves is required. This installation method ensures the mud flaps are tightly secured, reducing the risk of flapping into the tires.

  • Custom Fit for GMC Sierra 3500 HD: Specifically designed for 2015-2019 dually models, providing tailored coverage for both front and rear tires.
  • Officially Licensed GMC Logo: Features a stainless steel plate with the iconic GMC logo and black vinyl overlay, adding a premium, branded look to your truck.
