PRIOR TO INSTALLATION

  • A) Install the flares according to these written instructions with the hardware provided.
    WARNING: Failure to install according to these instructions will invalidate the warranty. This includes, but is not limited to, using alternative installation methods, hardware, or materials. DO NOT USE:
    Loctite, Superglue, or similar products on the hardware or the flares.
    Install flares on cleaned vehicle surfaces.

  • B) Fit: Verify the fit of the flares to the vehicle before installation (some filing, sanding, or cutting may be necessary to ensure proper fit).

  • C) Painting: (Optional) If painting is desired it must be done before installing flares on the vehicle. Clean the outer surface with a good-grade degreaser. DO NOT USE LACQUER THINNER OR ENAMEL REDUCER AS A DEGREASER. Wipe the outer surface thoroughly with a tack rag before painting. Application of plastic adhesion promoter for ABS plastic as per your paint system manufacturer’s recommendations is required. Paint flares using a high-quality enamel, or polyurethane automotive paint. If painting edge trim (not recommended), use a flex additive.

  • D) Performance: Using larger tyres may increase the area required to turn the vehicle. Some tyre/rim combinations may require lowering bump stops and or installing steering stops to prevent tire from contacting flare.

  • E) Exhaust System : Modifications may be necessary to maintain a minimum 4″ clearance between flares and exhaust pipes. (Exhaust gases should not vent directly onto flares)

  • F) Metal Protection: All exposed fasteners and bare metal should be treated with rust resistant paint BEFORE installing flares. Spray inner fender wells with undercoating AFTER flare attachments have been completed.

  • G) Decals: Flares may interfere with existing decals on the vehicle. If you wish, remove decals before the installation of flares.

  • H) Care & Cleaning: Fender flares are built to last; any detergent you use to wash your vehicle is sufficient to clean the flare. Do not use any harsh abrasive detergents.
