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 Love my Gatorback rear mud flaps!!  They are very heavy duty and give my new 2019 Ford F-350 a great look as well as protecting my paint.  Highly recommend these mud flaps.

Item is a little pricey, And will be some work to install on 2016 Ford F450 but can and will be done, Not happy that Gatorback does not make a front mud flap for the F450 in fact they don't even show F450 as and option on their web site.

These are the best mud flaps, heavy duty.
I am not drilling holes

I thought when I ordered these mud flaps they were the clip-on you know far as using the existing grommets that are already in the fender wells. I'm not drilling holes in the fenders of my truck. Pay $107,000 for a new truck and you're not going to day. Going to drill holes and fenders. There are some I thought gatorback was the ones you didn't have to drill holes but I guess not. I will be contacting customer service. I will be returning these mud flaps cuz I like I said I am not drilling holes

Thank you for the feedback. With the flaps to install them without drilling into the body of the truck you will want the custom fit mounting brackets, https://www.sharptruck.com/truck-hardware-gb759895

These are custom fit for the 2017-2022 Ford F-350,F-450 and F-550 dually trucks

I need to replace the driver side rear Can I just buy one

- Paul on 6/6/2019

The rubber portion is covered by a lifetime warranty. If you send a pic to [email protected] i can get a warranty claim started. The stainless plate can be transferred if it is not damaged.

if you need a plate those can be purchased individually here, www.sharptruck.com/truck-hardware-gatorback-ford-replacement-plate

What does the slotting of the mud flap do?

- Angela on 11/17/2019

The flaps need to be mounted to brackets, with the slots they will install on the custom fit no drill mounting brackets right out of the box. You will not have to put the slots in yourself

- Admin on 11/18/2019

is this for a dually f350

- sheila on 12/12/2020

Yes, these flaps are for a dually. You would need an install bracket. The part number would depend on the year Super Duty. You can see the custom fit brackets here, www.sharptruck.com/truck-hardware-custom-fit-mud-flap-brackets
