Gatorback Plate Finishes

Here are the different plate finishines

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 was completely satisfied with my purchasing experience at sharptruck. After conversing with a rep in customer service and getting complete and very informative information from him I decided to order gatorback mudflaps, a front and rear set, plus custom rear brackets for the rear installation on my 2016 GMC Sierra. My shipment arrived a few days after confirmation as was promised. Everything was intact with install instructions. The price was right and the quality of the product was exceptionable. It was a pleasure doing business with Sharptruck and I plan to do more in the future.
Looks good!

Really like the color and lettering on bright stainless steal . They are heavy duty to help keep rocks down from chipping the paint .

Do you have a mudflap that fits over factory installed splash guards?

- Russell Bunkelman on 4/28/2024

This set will fit on the 2018 and older Sierra 1500 and 2019 and older HD single rear wheel trucks. Those vehicles have a factory flap that need to be removed if it is on the truck

Truck Hardware Gatorback Red "GMC" Logo Mud Flaps - Set

Elevate the style and protection of your GMC Sierra with the premium Truck Hardware Gatorback Red "GMC" Logo Mud Flap Set. Specifically designed for 2014-2018 GMC Sierra 1500, 2019 GMC Sierra 1500 Limited, and 2015-2019 GMC Sierra 2500 HD/3500 HD (Single Rear Wheel), these mud flaps provide a perfect fit and exceptional protection. Whether navigating city streets or tackling rugged off-road terrain, these mud flaps ensure your truck remains shielded from the elements while adding a distinct visual flair.

Crafted from 1/2" thick, heavy-duty virgin rubber, these 12" wide mud flaps offer superior strength, flexibility, and resistance to cracking, fading, and warping. Virgin rubber is renowned for its enhanced durability compared to recycled alternatives, making these mud flaps highly resilient against the harshest elements. The result? Your vehicle stays cleaner, and your truck's paint and body remain free from damage caused by rocks, mud, gravel, and road debris. The striking red "GMC" logo adds a touch of boldness to your truck, showcasing an officially licensed design that is die-stamped into a stainless steel plate, ensuring a premium finish.

The Gatorback series by Truck Hardware is synonymous with the highest quality in heavy-duty mud flaps. These mud flaps are engineered for an exact fit, leveraging premium-grade materials that guarantee longevity and resistance to wear. This set includes both front and rear mud flaps, each designed to align precisely with your vehicle’s factory fasteners, ensuring an easy and secure installation process.

The front mud flaps provide 5" of tire coverage from the bottom of the fender to the bottom of the flap, while the rear flaps offer 7.5" of tire coverage. This extensive coverage protects your truck from chips, scratches, and debris, preserving the vehicle’s appearance in all driving conditions. The weight and design of these mud flaps ensure they stay firmly in place, preventing any "sailing" during high-speed or off-road driving.

Key Features

  • Heavy-Duty Virgin Rubber Construction: Made from 1/2" thick premium virgin rubber, these mud flaps offer long-lasting durability and are resistant to cracking, fading, and warping. Virgin rubber provides unmatched strength and flexibility, ensuring your mud flaps maintain their integrity over time.
  • Custom-Fit Design: Specifically engineered for 2014-2018 GMC Sierra 1500, 2019 GMC Sierra 1500 Limited, and 2015-2019 GMC Sierra 2500 HD/3500 HD models. The set includes custom-fit rear support brackets (GB756802) to provide added stability and prevent movement during tough driving conditions.
  • Officially Licensed Red GMC Logo: The stainless steel plates feature a high-quality, die-stamped red GMC logo with a hand-applied vinyl overlay, offering a bold and professional look.
  • Complete Tire Coverage: The front mud flaps provide 5" of tire coverage, while the rear flaps provide 7.5". This ensures maximum protection from road debris and environmental damage, keeping your truck looking its best.

Installation

Front Flap Installation: The front mud flaps attach directly to the lip of the wheel well using self-tapping screws, with the option to utilize existing factory fasteners if available. The installation process is straightforward, requiring only basic tools for a hassle-free experience. Ensure at least 1/2" of clearance between the tires and the wheel well to accommodate the flap thickness. The front flaps install flush with the wheel well, allowing seamless integration with other accessories like step bars, power boards, or side steps.

Rear Flap Installation: The rear mud flaps are secured using custom-fit rear support brackets and self-tapping screws to hold them tightly against the wheel well. This minimizes movement and prevents the flaps from flapping into the tires, ensuring longevity even in harsh driving environments.

What's Included

  • (2) Front Mud Flaps - 12" x 23" (GB1223CUTG-R)
  • (2) Rear Mud Flaps - 12" x 23" (GB1223G-R)
  • Custom Rear Support Brackets (GB756802)
  • Stainless Steel Self-Tapping Mounting Screws

Care & Maintenance

To maintain the performance and appearance of your Gatorback Mud Flaps:

  • Rubber Flaps: Clean periodically with mild soap and water to remove dirt, grime, and road salt.
  • Stainless Steel Plates: Wipe down with a non-abrasive cleaner to maintain the polished finish.
  • Inspect mounting hardware regularly to ensure it remains secure, especially after off-road use or exposure to harsh weather conditions.

Manufacturer Warranty

Gatorback mud flaps are backed by a limited lifetime warranty. This warranty covers rubber replacement (e.g., tear-offs) for the lifetime of the product for the original owner. It does not cover damage caused by abuse or normal wear and tear on brackets, plates, or mounting hardware.

Terms

  • Virgin Rubber: Rubber that has not been recycled or reprocessed, offering superior durability, flexibility, and resistance to wear compared to recycled rubber.
  • Self-Tapping Screws: Screws designed to drill their own hole as they are driven into materials such as metal or plastic, simplifying the installation process.
  • Die-Stamped: A process where the logo is stamped into the metal plate, ensuring a precise, consistent, and high-quality finish.
  • UV-Resistant: The rubber material is treated to resist damage from ultraviolet (UV) light, preventing cracking or fading over time.
