GMC Sierra HD Mud Flap Differences

Product Overview

Gatorback Plate Finishes

Here are the different plate finishes

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.
