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.

Denali Mud Flaps - Front and Rear
5
These are some really nice mud flaps. They appear to be solid and heavy duty. The installation instructions weren't all that great since the hardware was labeled differently on the "Items included" page than they were on the installation instructions but if you are mechanically inclined, its not hard to figure out. The fronts were really easy but the rears were a little tricky since I decided to keep the inner fender liner. I am very pleased with the finished product.

The substantial width and weight of the rear mud flaps prevent them from "sailing" at highway speeds, keeping them securely in place. The rear flaps not only protect your truck but also safeguard any trailers or vehicles behind you from flying debris, ensuring a safer ride for everyone.

Heavy-Duty Rubber Construction with Black Wrap Denali Branding

Constructed from 1/2" thick virgin rubber, these Gatorback mud flaps are built to last, providing superior durability and flexibility. Virgin rubber is highly resistant to impacts and wear, ensuring that the mud flaps maintain their effectiveness and aesthetic appeal for years.

The black wrap finish offers corrosion resistance and a refined appearance, making these mud flaps both functional and stylish.

Custom Fit Finishing Caps for a Seamless Appearance

This set also features custom fit finishing caps that provide a polished, professional look while securing the mud flaps in place. The finishing caps have an OEM-like texture that matches the truck's original equipment, ensuring a cohesive, factory-finished appearance.

Easy, No-Drill Installation

The Gatorback Black Wrap "Denali" Logo Mud Flaps are designed for no-drill installation. Using the truck's existing factory mounting points and high-quality 3M automotive-grade adhesive tape, these mud flaps can be securely installed without drilling into the truck's body. The set includes custom brackets and all necessary hardware, making the installation process straightforward and convenient with common household tools.

Product Care & Maintenance:
