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.

These gatorback mudflaps are made strong but give your truck a stylish look and really do a great job of keeping the snow and mud/ rocks from collecting or chipping the back lower parts of your pickup bed!  They also keep the backside of you rear bumper free of packed snow.  Yeah they are a little pricey, but they are built to last!!
A must have

Truck Hardware Gatorback Stainless Plate Mud Flaps - Set

Add both functionality and style to your Chevy Silverado with the Truck Hardware Gatorback Stainless Plate Mud Flap Set. Crafted to fit 2014-2018 Chevy Silverado 1500, 2019 Chevy Silverado 1500 Legacy, and 2015-2019 Chevy Silverado 2500 HD/3500 HD (Single Rear Wheel), these mud flaps feature premium-quality stainless steel plates, adding a sleek and durable touch to your truck.

Designed for a perfect fit, these mud flaps are 12" wide and made from heavy-duty, 1/2" thick rubber that offers complete tire coverage. The weight of these flaps ensures they remain in place without "sailing" when driving at higher speeds. They help to keep your vehicle cleaner for longer while protecting it from rocks, mud, gravel, and snow. These mud flaps are built to prevent debris from damaging your vehicle's paint and reduce buildup on your step bars, making them a highly functional accessory.

The Truck Hardware Gatorback series is known for its top-quality heavy-duty construction. Featuring rugged 1/2" thick rubber and stainless steel plates, these mud flaps combine the highest level of protection and aesthetic appeal, making them the ideal choice for any Silverado owner looking to upgrade both style and functionality.

Installation

Front Flap Installation: The front flaps attach directly to the lip of the wheel well using self-tapping screws. Existing factory fasteners can also be used if available. The installation is simple and requires only basic tools. Allow at least 1/2" of clearance between the tires and the wheel well to accommodate the thickness of the flap. The front flaps sit flush with the wheel well, allowing compatibility with step bars, power boards, or side steps.

Rear Flap Installation: The rear flaps are fastened using custom-fit support brackets along with self-tapping screws to ensure they remain securely in place. This prevents them from flapping into the tires and maintains their stability even in challenging driving conditions.

Key Features

  • Premium Heavy-Duty Rubber: Made from 1/2" thick, UV-resistant rubber for maximum durability and to withstand harsh environments.
  • Sleek Stainless Steel Plates: The polished stainless steel plate measures 10 1/4" x 5" and adds a classic touch to your truck's appearance.

  • Rear Support Brackets for Stability: Includes custom-fit rear support brackets to ensure the mud flaps stay securely attached under all driving conditions.

Care & Maintenance
