GMC Sierra HD Mud Flap Differences

Product Overview

Gatorback Plate Finishes

Here are the different plate finishes

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.

  • Black Anodized Plates

    Anodized aluminum is a durable, corrosion-resistant material featuring a specialized coating that enhances protection against rust while providing an attractive finish. To preserve its appearance and functionality, appropriate cleaning methods are essential. Incorrect cleaning practices may compromise the coating, resulting in fading or pitting. This guide provides detailed instructions on maintenance, including routine procedures, advanced cleaning techniques, precautions, and considerations regarding touch-free car washes.

    Routine Cleaning and Preventive Maintenance

    Regular cleaning is necessary to prevent the accumulation of contaminants that could impair the surface. Employ non-abrasive methods to safeguard the thin protective layer.

      • Frequency: Perform cleaning every 3 months, or more frequently in environments with high pollution, proximity to coastal areas (where salt may accelerate corrosion), or high usage.
      • Basic Method:
        • Begin by rinsing with plain water to remove loose debris. Utilize a soft sponge or cloth for gentle wiping.
        • For minor soiling, prepare a solution of mild, pH-neutral soap (such as dish detergent) with warm water. Apply using a soft cloth, employing circular motions without excessive force.
        • Rinse thoroughly with clean water to eliminate any residue.
        • Dry the surface promptly with a soft towel to avoid water spots.
      • Tools: Select non-abrasive items such as soft-bristle brushes or cloths. Avoid steel wool or abrasive pads, as they may scratch and damage the coating.
      • Preventive Measures:
        • Apply a suitable protective wax or sealant designed for anodized aluminum following cleaning (e.g., automotive-grade waxes for vehicle parts).
        • In urban or industrial settings, monitor for acidic precipitation or organic deposits, which may etch the surface if not addressed promptly.
        • Store items indoors when feasible to mitigate ultraviolet fading of colored finishes.

    Deep Cleaning for Persistent Contaminants

    For significant buildup, such as oxidation or embedded grime, employ more intensive yet cautious approaches. Always test methods on an inconspicuous area first.

      • Mild Abrasive Methods: Form a paste with baking soda and water for gentle application with a soft cloth, followed by thorough rinsing. For oxidized sections, use fine-grit sandpaper (600-1000) lightly with water and polish afterward, though this should be infrequent to prevent thinning the coating.
      • Commercial Products: Select cleaners formulated for anodized aluminum with a neutral pH. Citrus-based options are suitable; refrain from using unverified household cleaners.

    Practices to Avoid

    Anodized aluminum is susceptible to substances that may dissolve or abrade its protective oxide layer.

      • Harsh Chemicals: Refrain from using strong acids (e.g., hydrochloric or phosphoric) or alkalis (e.g., sodium hydroxide), as they may cause etching, discoloration, or removal of the finish.
      • Abrasive Tools: Avoid vigorous scrubbing implements or polishes that could dull the surface and expose the base metal.
      • High-Pressure Washing: While suitable for initial rinsing, limit pressure to under 1,000 PSI to prevent intrusion into seams.
      • Environmental Exposures: Minimize contact with chlorine, fluoride, or heavy metals, which may induce pitting.

    Impact of Touch-Free Car Washes on Anodized Aluminum

    Touch-free car washes offer convenience and minimize paint scratches by employing high-pressure jets and chemical applications without physical contact. However, they may adversely affect anodized aluminum elements, such as trim or wheels, owing to the intensity of the processes and chemicals.

      • Potential Damage: These systems frequently utilize high-pH alkaline detergents and acidic pre-treatments that can interact with the coating, leading to discoloration, dulling, etching, or fading. Alkaline agents are particularly detrimental, potentially dissolving the layer and resulting in a chalky or pitted appearance. Repeated use may exacerbate issues, especially on colored anodizing, causing inconsistent hues or loss of gloss.
      • Risk Factors: The absence of mechanical brushing necessitates more potent chemicals and elevated pressures (up to 1,500 PSI), which may infiltrate seals or aggravate minor imperfections. Although generally compatible with standard automotive paint, these washes can deplete protective sealants on anodized components more rapidly.
      • Recommendations: Avoid touch-free car washes for items featuring anodized aluminum whenever possible, particularly those with high-alkaline formulations. Prefer manual washing with pH-neutral solutions. If utilization is necessary (e.g., for seasonal salt removal), rinse affected areas thoroughly afterward and apply a protective coating. Verify the chemical composition of the wash or conduct a test on a small section if gentler options are claimed.

    Common Harsh Chemicals in Touch-Free Car Washes

    Touch-free systems depend on robust chemical blends for effective cleaning without contact. These typically include:

      • Alkaline Detergents: High-pH (9-14) compounds such as sodium hydroxide or potassium hydroxide, which emulsify oils and grime but may etch anodized aluminum by eroding the oxide layer.
      • Acidic Pre-Treatments: Low-pH (2-5) solutions incorporating hydrofluoric acid, phosphoric acid, or citric acid to dissolve mineral deposits and salts. These can induce pitting or discoloration if not adequately neutralized.
      • Surfactants and Solvents: Components like volatile organic compounds (VOCs), glycol ethers, or petroleum distillates that facilitate cleaning but may include irritants capable of degrading seals and finishes over time.
      • Additional Agents: Chelating compounds, foam enhancers, or corrosion inhibitors intended for protection, yet potentially abrasive in elevated concentrations. Multi-step processes alternating acidic and alkaline applications heighten risks for sensitive materials such as anodized aluminum.

    These formulations prioritize efficiency and compatibility with paint, rendering them less ideal for specialized coatings like anodized aluminum.

    Effective maintenance of anodized aluminum requires consistent application of gentle, neutral cleaning agents to prolong its durability and preserve its attributes. By eschewing aggressive chemicals and abrasive techniques, irreversible damage can be averted. Although touch-free car washes provide convenience, their dependence on potent alkaline and acidic substances presents notable risks to anodized surfaces, potentially causing discoloration or deterioration—manual methods are preferable where feasible. In the event of damage, seek professional assistance for restoration. Adhering to these recommendations will ensure the material retains its optimal condition for an extended period.
