Gatorback Plate Finishes

Here are the different plate finishes

At a glance

Customer sentiment is overwhelmingly positive: buyers repeatedly praise Gatorback/SharpTruck mud flaps as premium, heavy‑duty, great-looking, vehicle-specific products that provide excellent protection, with standout customer service and fast shipping. The main negatives are high price, occasionally challenging/long installations (especially rears/dually), and periodic hardware/instructions/packaging issues or minor fitment quirks on certain trims/oversized tires.

What Customers Liked

  • Thick/heavy rubber, substantial weight, rugged/OTR-grade feel; holds up for years (5–10+ years reported), flexible in cold/snow, doesn’t “sail” at highway speed; strong brackets add stability.
  • Look “sharp,” “classy,” and OEM-like; logo/plate options (Ford/Chevy/Ram/AT4X/Z71/flags, etc.) get many compliments and add ‘pop’.
  • Many report perfect fit/‘like a glove,’ good tire coverage, options for offsets/oversized tires (e.g., offset versions preventing rubbing), adjustable positioning via slotted holes.
  • Significantly reduces mud/road salt/slush on running boards/steps and sides; helps prevent rock chips and protects trailers/RVs/boats; improves cleanliness on gravel/dirt roads and in winter conditions.
  • Often installs using factory holes and avoids drilling into metal body; videos and written instructions frequently cited as helpful; many install without removing wheels (fronts especially).
  • Consistently praised for responsive support, warranty replacements for tears/rips, quick resolution of shipping damage/wrong parts/missing items, and proactive communication/updates.
  • Fast delivery (often 2–5 days), accurate orders/fitment tools, good packaging noted by many; easy ordering and exchanges/returns.
  • Removable lower section on some models appreciated for added clearance during off-roading, then quick reinstall.

Things to Consider

  • Frequently described as expensive/‘hard pill to swallow’ (some citing $600–$1000+), though many still say it’s worth it.
  • Rears and dually setups often challenging/time-consuming; some recommend removing rear wheels, using a right-angle drill, clamps, or a helper; alignment can take time.
  • Some find written directions vague/confusing; hardware not clearly labeled (washers/spacers), left/right not distinguished, videos not always model-specific; “no-drill” marketing criticized when drilling in liners/plastic is still required.
  • Occasional missing screws/washers/clips/parts; mixed metric/SAE hardware complaints; plastic fasteners/clips stripping or pulling out; desire for stainless/black hardware and better washer/spacer labeling.
  • Some reports of rubbing with oversized tires/turning lock; minor misalignment of holes/templates; driver/passenger side fit differences; not perfect fit for some newer model years or with wheel-well liners/fender flares/steps.
  • Several note rear support brackets feel ‘necessary’ but are not always included; frustration at needing to add brackets separately or not being told upfront.
  • A few cases of brackets coming loose in transit causing scratches; damaged outer boxes; occasional wrong color/plate shipped.
  • Silver fasteners/washer heads stand out; some plates/finishes streak or rust (rare report of rust forming on logo); desire for thicker metal in certain kits.
  • Some note flaps hang low for off-road use; risk of tearing in deep snow, tall grass, or trail obstacles (though removability helps on some models).

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.

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.
