The Truck Hardware Gatorback "Duramax" Logo Dually Mud Flaps & Caps - Set is the ideal premium accessory for your 2020-2026 GMC Sierra 3500 HD Dual Rear Wheel truck. Featuring the iconic Duramax logo, this set provides superior protection while adding a distinct and powerful look to your vehicle. Designed to keep your truck and trailer protected from rocks, mud, gravel, and road debris, these mud flaps are built for durability and a stylish aesthetic that sets your truck apart. The Gatorback "Duramax" Logo Mud Flaps offer both maximum protection and a striking appearance that perfectly complements the performance of your truck.

Front and Rear Mud Flaps for Comprehensive Protection

This set includes two 12.5" wide front mud flaps and two 21" wide rear dually mud flaps. The front mud flaps offer 9" of tire coverage from the bottom of the fender, providing essential protection for your truck's front end. These flaps are designed to fit seamlessly with the truck's body lines, creating a factory-like appearance while effectively preventing mud, dirt, and road debris from causing damage to your truck's exterior.

The rear mud flaps are specifically crafted for maximum coverage of your dual rear wheel setup. With 21" wide coverage and 13.25" of protection from the bottom of the fender, these mud flaps ensure that debris is kept under control. The substantial width and weight of the rear mud flaps prevent them from "sailing" at highway speeds, keeping them securely in place. The rear flaps not only protect your truck but also safeguard any trailers or vehicles behind you from flying debris, ensuring a safer ride for everyone.

Heavy-Duty Rubber Construction with Premium Duramax Branding

Constructed from 1/2" thick virgin rubber, these Gatorback mud flaps are built to last, providing superior durability and flexibility. Virgin rubber is highly resistant to impacts and wear, ensuring that the mud flaps maintain their effectiveness and aesthetic appeal for years. The "Duramax" logo plates are die-stamped and officially licensed by GMC, adding a touch of bold style and power to your truck. The 304 stainless steel plates are designed to be both functional and visually appealing, offering resistance to corrosion while highlighting the rugged Duramax branding.

Custom Fit Finishing Caps for a Seamless Appearance

This set also features custom fit finishing caps that provide a polished, professional look while securing the mud flaps in place. The finishing caps have an OEM-like texture that matches the truck's original equipment, ensuring a cohesive, factory-finished appearance.

Easy, No-Drill Installation

The Gatorback "Duramax" Logo Mud Flaps are designed for no-drill installation. Using the truck's existing factory mounting points and high-quality 3M automotive-grade adhesive tape, these mud flaps can be securely installed without drilling into the truck's body. The set includes custom brackets and all necessary hardware, making the installation process straightforward and convenient with common household tools.

Key Features:

  • "Duramax" Logo Plates: The die-stamped logo plates are officially licensed and provide a powerful look that complements the GMC Sierra's styling while offering corrosion resistance.
  • Heavy-Duty Virgin Rubber Construction: The 1/2" thick rubber provides excellent durability, flexibility, and protection from road debris.
  • Wide Rear Flaps for Dually Trucks: The 21" wide rear mud flaps offer comprehensive protection for the dual rear wheels, helping to keep your truck and anything behind it safe.
  • No-Drill Installation: Designed for quick and easy installation using factory mounting points, preserving your truck's original finish.

Terms:

The Truck Hardware Gatorback "Duramax" Logo Dually Mud Flaps & Caps set offers officially licensed GMC logos, delivering the perfect blend of style, protection, and durability for your GMC Sierra 3500 HD. Proudly made in Canada, these mud flaps are crafted to withstand tough conditions while keeping your truck looking rugged and powerful. With a limited lifetime warranty on the rubber portion, these mud flaps are an excellent investment in the long-term protection and appearance of your vehicle.

Warranty:

Gatorback mud flaps come with a limited lifetime warranty on the virgin rubber portion, covering replacement due to normal wear and tear for the lifetime of the product to the original owner. This warranty does not cover damage caused by abuse or regular wear and tear on brackets, plates, or mounting hardware.

Product Care & Maintenance:

  • 304 Stainless Steel Plates: Clean the 304 stainless steel plates using a soft cloth and a mild detergent cleaner. Avoid abrasive materials or harsh chemicals that could scratch or damage the surface. Rinse thoroughly with clean water and dry with a soft cloth to maintain the polished finish.
  • Virgin Rubber: To keep your mud flaps in top condition, clean them with a mild soap and water solution. Avoid using harsh chemicals or petroleum-based cleaners, as these can degrade the rubber over time. Rinse thoroughly and let them air dry for the best results.
