Product Overview

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.

These flaps are heavy duty and are absolutely secure once you get them installed.  Please see the view from inside the wheel well for the correct placement of all the necessary parts.  They are great looking as well as functional.  Colorado roads have lots of sand and gravel, I now do not have all that muck on my running boards or plastered all along the sides of my truck.  Great product but, comes at a price$$$

Look great and was what I was looking for I did front and rear mud flaps and very happy with quality and looks of them

I have a 2024 Dually high country with felt liners. I was told that you were working on a bracket to use for the felt liners. Has this been completed? Please let me know because I would like to order a set for my 2024 high country dually 3500.

Warranty

The Gatorback High Country Mud Flaps are backed by a limited lifetime warranty. This warranty covers the rubber portion against tear-offs for the lifetime of the product for the original owner. The warranty provides peace of mind, offering a replacement if the rubber flaps come off due to normal wear and tear. However, it does not cover damage resulting from abuse or regular wear on brackets, plates, or mounting hardware.

Product Care & Maintenance

  • High Country Stainless Steel Plates: To maintain the polished finish, clean the plates regularly with 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: Clean the rubber portion using a mild soap and water solution. Avoid harsh chemicals or petroleum-based cleaners, as these can degrade the rubber over time. Rinse thoroughly and allow the mud flaps to air dry for the best results.

For Chevy Silverado owners who want to combine bold protection with a sophisticated, premium look, the Truck Hardware Gatorback High Country Logo Dually Mud Flaps are an ideal choice. With enhanced coverage, effortless installation, and a luxurious High Country aesthetic, these rear mud flaps are designed to protect your truck from road debris while adding an upscale, distinguished appearance.
