At a glance

Overall sentiment is strongly positive: buyers consistently describe Gatorback/SharpTruck mud flaps as premium, heavy‑duty, great-looking, and highly effective at stopping rocks/mud/snow from hitting paint, steps, and trailers. The main reservations are the high price and occasional installation/fitment or hardware/packaging issues, which are often mitigated by responsive customer service and strong warranty support.

What Customers Liked

  • Thick, heavy rubber with substantial weight plates; feels “OTR/semi-truck grade,” doesn’t flap at highway speeds, flexible in cold weather, holds up through winters, gravel roads, mud, and years of use; many repeat buyers across multiple trucks.
  • Significantly reduces rock chips, road debris, mud/salt spray on paint, rocker panels, running boards/power steps, cameras, and keeps trailers/5th wheels/RVs cleaner and protected; coverage often better than OEM or plastic splash guards.
  • Looks “sharp,” classy, and truck-specific; logo/plate options (Z71, AT4X, Ford, Ram, Duramax, flags, black/satin/gunmetal/chrome) get compliments and help the truck stand out; finishing caps appreciated.
  • Many report perfect/vehicle-specific fit with factory-hole mounting, adjustable in/out positioning, good clearance with stock tires, and compatibility with certain trims/fender flares when configured correctly.
  • Generally described as straightforward with the right tools; helpful YouTube videos; bracket kits (especially rear/dually) add stability and make alignment easier; ability to install without removing wheels on some vehicles.
  • Frequent praise for fast shipping, responsive support, quick exchanges for wrong parts, replacement parts/plates/flaps shipped rapidly, and hassle-free warranty (including tears/rips or shipping damage).
  • Replaceable plates; removable lower section on some models for off-road clearance; ability to adjust flap stick-out; some like drilling only into plastic liner (not body).

Things to Consider

  • Most common complaint; many call them expensive/overpriced (often $600–$1000+), sometimes compounded by needing separate bracket kits/plates; some say alternatives may be “good enough” for less.
  • Mixed experiences: some installs are quick, others take hours—especially rear/dually, with wheel-well liners, rock rails/steps, or limited access; right-angle drill and/or removing rear wheels often recommended; alignment can be finicky.
  • Paper instructions sometimes vague, lacking steps, inconsistent with videos, or confusing (hardware ID, left/right orientation, templates, washer placement); requests for better labeling, templates, and model-specific videos.
  • Occasional reports of holes not lining up, needing to drill/elongate slots, bend/trim brackets, trim liners/trim pieces, or create homemade brackets; some rubbing with oversized tires/offset wheels; a few cases of poor fit on specific trims/years.
  • Multiple reviewers note drilling is still required (usually into plastic liner or flap), so ‘no-drill’ feels misleading in some kits.
  • Some dislike plastic clips/nut inserts pulling out/stripping, mixed metric/SAE hardware, bolt length issues, flimsy/galvanized or plastic brackets at high price, silver hardware visible (wish black), occasional missing/mismatched hardware or parts.
  • Some flaps/plates arrived scuffed/scratched or boxes damaged; brackets loosening in transit; a few wrong items shipped or missing pieces (spacers/washers/clips), though support often resolves quickly.
  • Some note low ground clearance depending on model/height; concerns about snagging in deep snow, tall grass, or off-road obstacles; some wish flaps were longer/shorter depending on use.
  • Plate finish can streak/stain (e.g., gunmetal), color/gloss differs from expectations, logos not level in a few cases, and some wish flaps came pre-slotted/pre-drilled for easier install.

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.
