Gatorback Plate Finishes

Here are the different plate finishes

At a glance

Overall sentiment is overwhelmingly positive: customers consistently describe Gatorback/SharpTruck mud flaps as premium, heavy-duty, great-looking products that provide excellent protection, with standout customer service and warranty support; the main negatives are high price and occasional installation/hardware/fitment frustrations.

What Customers Liked

  • Thick, heavy rubber with a substantial feel; durable, flexible in cold/snow/ice; doesn’t “sail” at highway speeds; plates/weights feel robust and can be replaced/swapped.
  • Significantly reduces rock chips, mud/salt spray, and slush on rocker panels, running boards/power steps, bumpers, trailers/RVs; many note cleaner sides and less debris noise on gravel roads.
  • Vehicle-specific fit often described as ‘like a glove’/OEM; finishes (chrome, gunmetal, black plates) and logo plates (Z71/AT4X/FX4/Ram/Ford/Chevy, flags, etc.) ‘make the truck pop’ and draw compliments.
  • Many report straightforward installs, especially after the first flap; helpful YouTube videos; slotted holes help leveling; adjustable stick-out; removable lower section appreciated for off-roading/clearance.
  • Fast shipping is frequently praised; responsive support for exchanges/mis-shipments/damaged parts; hassle-free warranty replacements (torn/ripped flaps or scratched plates) often sent quickly.

Things to Consider

  • Most common complaint: ‘pricey/overpriced’ (often $600–$1000 with brackets/plates). Some feel brackets/plates should be included at that price.
  • Installs can be time-consuming or awkward (especially rears/dually setups), sometimes requiring wheel removal, right-angle drill, extra hands, drilling into plastic liners, trimming liners/trim pieces, or drilling/slot-cutting templates.
  • Paper instructions sometimes lacking, confusing, or mismatched vs video; hardware bags not well-separated/labeled; left/right not always marked; templates/printer scaling issues; ‘no-drill’ marketing criticized when drilling plastic is required.
  • Occasional reports of cheap/fragile fasteners, plastic clips/nut inserts pulling out/stripping, mixed metric/SAE heads, silver hardware being visually noticeable, bracket thickness/material concerns (plastic/galvanized vs stainless), and clamp-on brackets potentially rubbing paint (suggest PPF/tape).
  • Some vehicles need hole elongation, bracket bending, or ‘gerry-rigging’; occasional rubbing with oversized tires/offset wheels; a few reports of mis-shipped parts (two rears), wrong plates/colors, missing washers/spacers/clips/screws, or shipping scuffs/scratches/damaged boxes.

my dually and front flaps. looks great! Thanks
Silverado Dually Gatorback Mud Flaps

5 years ago, I purchased a new 2019 3500HD. After much research, I bought the Gatorback Mud Flaps. They’re not cheap, but they are by far the best. After 5 years of absolutely no issues, I traded my 2019 with 140,000 miles, for a new 2024 Silverado Dually. Guess what the first accessory I purchased?  That’s right, Gatorback Mudflaps.

I cannot say enough good things about this company. Had trouble with my original purchase, called and talked to Matt. No questioning no hesitation said we’ll make it right and I’ll next day air the parts to you. Not only did he next day air them, he sent me a whole new mid flap kit! That’s how business should be ran! I can name multiple outlets that need a lesson from these guys. If you want outstanding customer service buy from these guys. If you want no service choose from many of the big box places. Thanks again for getting me fixed up guys. I will definitely recommend and be back! Installed gatorbacks on a 22 Chevy 2500.

The Truck Hardware Gatorback Rubber Dually Mud Flaps - Set is the ideal choice for owners of 2020-2026 GMC Sierra 3500 HD Dual Rear Wheel trucks looking for durable protection without compromising on appearance. These mud flaps are designed to offer comprehensive coverage against road debris, mud, gravel, and other elements, ensuring that your truck and anything it’s towing remain protected from the rigors of the road. Built with high-quality materials, these mud flaps are made to endure the toughest conditions, making them a smart investment for your truck's long-term safety and appearance.

Front and Rear Mud Flaps for Complete Protection

This set includes two 12.5" wide front mud flaps and two 21" wide rear dually mud flaps. The front flaps provide 9" of tire coverage, delivering effective defense against road spray and preventing rock chips on your truck's paint, step bars, and running boards. These flaps are crafted from heavy-duty virgin rubber, ensuring maximum flexibility and durability. The front mud flaps are designed to follow the truck's body lines closely, maintaining a clean, factory-like appearance while delivering high-impact protection from road hazards.

The rear mud flaps offer 13.25" of tire coverage, giving full protection to your dually truck's wider rear wheels and anything behind you. The rear flaps are 21" wide and weigh 10 lbs each, providing substantial weight to minimize movement while driving, even at high speeds. This means that you can trust these mud flaps to stay firmly in place, keeping your truck, trailer, and other road users protected from road debris and minimizing the chances of “sailing” at highway speeds. The robust rubber construction guarantees longevity and resistance to wear and tear, making these rear flaps an excellent option for truck owners who need reliable, long-term protection.

Heavy-Duty Rubber Construction for Reliable Performance

Constructed from 1/2" thick virgin rubber, these Gatorback mud flaps are engineered to withstand the toughest environments and protect your vehicle from all sorts of debris. Virgin rubber is known for its high durability and flexibility, allowing the mud flaps to absorb impacts and maintain their shape over time. Unlike recycled rubber, virgin rubber provides a longer-lasting solution that resists cracking, tearing, and deformation, ensuring your truck is well-protected for years to come.

Custom Fit Finishing Caps for a Seamless Look

The Gatorback Rubber Dually Mud Flaps set includes custom-fit finishing caps that help create a clean, polished, and OEM-style look, seamlessly blending the mud flaps with your truck's design. These finishing caps are designed to cover the areas where the mud flaps attach, enhancing the visual appeal and ensuring a smooth, factory-quality appearance that sets your truck apart.

Simple No-Drill Installation

These Gatorback Rubber Dually Mud Flaps are designed for no-drill installation using factory mounting points. Installation is straightforward and can be completed using common household tools, preserving your truck's original finish without the need for additional drilling. The mud flaps include all necessary mounting hardware and brackets, ensuring a secure fit that stays in place through all driving conditions. Additionally, strong 3M automotive-grade adhesive tape is used for added security, especially for the finishing caps, providing a long-lasting, dependable installation.

Key Features:

  • Heavy-Duty Virgin Rubber Construction: The 1/2" thick virgin rubber provides superior durability and resistance to road debris.
  • Wide Rear Flaps for Dually Trucks: The 21" wide rear mud flaps offer full tire coverage, protecting your truck, trailer, and other road users from mud, dirt, and rocks.
