Truck Hardware Gatorback "Duramax" Logo Dually Mud Flaps - Set

For truck owners who want premium protection with a bold representation of power, the Truck Hardware Gatorback "Duramax" Logo Dually Mud Flaps are the ideal choice. Specifically designed for 2015-2019 Chevy Silverado and GMC Sierra 3500 HD (Dually Rear Wheel) models, these mud flaps deliver both unparalleled functionality and a distinctive aesthetic appeal. Crafted with precision and high-quality materials, these mud flaps are perfect for truck owners who value durability and style.

Built from heavy-duty virgin rubber, the Gatorback Duramax Dually Mud Flaps are engineered to withstand the toughest road conditions while maintaining flexibility and resilience. Each rear flap weighs 10 pounds, ensuring they stay firmly in place without 'sailing' or shifting, even at high speeds. These mud flaps provide extensive tire coverage—5 inches for the front and 9.5 inches for the rear—offering superior protection against rocks, mud, and other debris that could damage your truck's finish. The officially licensed Duramax logo is die-stamped into a durable stainless steel plate with a hand-applied vinyl overlay, adding a professional and premium look that reflects the power of the Duramax engine.

The stainless steel plate with the Duramax logo adds a distinctive element that complements your truck's bold design while also offering added durability. The darkened stainless steel finish provides a polished look, ensuring that your mud flaps maintain their premium appearance over time.

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 securely in place even under challenging conditions. The rear brackets utilize existing factory holes, eliminating the need for drilling into the truck body, though drilling through the mud flaps themselves is required. This installation method ensures that the mud flaps are tightly secured, reducing the risk of flapping into the tires. The rear plates, measuring an impressive 17 1/4" x 5", provide a bold and distinctive visual element to your truck.

Questions & answers

1 question

Question: Mikes comment on February 22 shows the Mudflaps as being too small!

Asked by Steven Boyd 4/28/2023

Answer from the SharpTruck team: Hello Steven, it looks like Mike has oversized tires on the truck which is why there is not full tire coverage. Gatorback does have a dually offset bracket for instances like that.
