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 just ordered these mudflaps the other day, The website was easy to navigate and the checkout was painless. My order arrived in just a couple of days. Mounting was fairly easy, and the fitment is VERY GOOD. I would recommend this product to anyone!

will these fit on a 2022 GMC 2500 HD? or, can you send me links to ones that will? Thank you!

Full Coverage for Ultimate Protection

The Gatorback Rubber Mud Flaps are engineered to provide comprehensive tire coverage for your GMC Sierra 1500. Each mud flap is constructed from 1/2" thick heavy-duty virgin rubber and measures 12" wide.

These mud flaps fit flush within the wheel well, maintaining a cohesive and polished look for your truck.

For a complete look after the removal of OEM protectors, Truck Hardware Sierra 1500 Finishing Caps (sold separately) are recommended. These finishing caps provide an OEM-like appearance, ensuring your truck retains a polished look with no cutting or modifications required.

Heavy-Duty Construction for Long-Lasting Performance

The Gatorback Rubber Mud Flaps are crafted from virgin rubber, known for its superior durability and resilience. Unlike reclaimed rubber, virgin rubber maintains its flexibility, making these mud flaps ideal for protecting against even the harshest elements. The flaps are designed to minimize sail, staying securely in place even at highway speeds, ensuring dependable performance mile after mile.

Key Features

  • Heavy-Duty Virgin Rubber Construction: Built from premium virgin rubber for excellent durability, offering long-lasting protection for your truck.
  • Comprehensive Tire Coverage: Front mud flaps extend 6.5" below the fender, and rear mud flaps extend 7", providing full tire coverage against road debris.

Terms

  • Virgin Rubber: Rubber that has not been recycled, offering superior durability and flexibility compared to reclaimed rubber.
  • OEM (Original Equipment Manufacturer): Refers to parts made by the original vehicle manufacturer, ensuring compatibility and quality. These mud flaps are designed to work with OEM mounting points for an ideal fit.
  • Sail: The movement of mud flaps due to wind or speed, which can reduce their effectiveness. These mud flaps are designed to minimize sail, keeping them securely in place.

Warranty

Truck Hardware Gatorback Rubber 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 offers peace of mind, providing 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

  • 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.
  • Finishing Caps: To maintain the appearance and longevity of the finishing caps, clean them regularly with a mild soap and water solution. Avoid abrasive materials or harsh chemicals that could damage the surface. Rinse thoroughly and allow the caps to air dry for the best results. Routine care will help preserve their quality and ensure that they continue to look great on your truck.
