Please read instructions entirely before installing this product.


Ensure that both left and right hand Fender Flares suit the profile of the vehicle. Note the areas where the Fender Flares come in contact with the vehicle. NOTE: Before fitting Fender Flares remove any moldings, strips or existing flares from the wheel arch. If there is a body side molding, mark where the molding is to be cut, alternatively the Fender Flare can be cut to go around the molding. Be sure to allow enough room for the extrusion.

*PRIOR TO ANY PAINTING & INSTALLATION, PRODUCT SHOULD BE THOROUGHLY INSPECTED FOR ALL COMPONENTS LISTED ABOVE. PRODUCT SHOULD ALSO BE TEST FITTED PRIOR TO ANY PAINTING & INSTALLATION. PLEASE CONTACT SMITTYBILT IF YOU HAVE ANY FITMENT QUESTIONS AND OR MISSING COMPONENTS.

PAINTING INSTRUCTIONS – If Fender Flares are being painted; do not install edge extrusion until painting is complete. Prior to painting, clean all surfaces to be painted using clean water and a mild detergent, do not use lacquer thinner or any solvent based products. Wipe completely dry. Best results will be achieved by wiping the areas to be painted with a tack rag just prior to painting. Most automotive paints can be applied directly to the Fender Flares, however some may require a primer (check paint manufacturer specifications). Good adhesion will be achieved without sanding. Select a paint (and primer if necessary) that is suitable for rigid plastics PMMA (Acrylic). If using a paint system that requires baking, do not expose the product to temperatures above 70°C (158°F). Do not fit the extrusion or any of the hardware to the Fender Flares until the paint is completely dry.

STEP 1: Attach the 9 bolts, washers and nuts to each Fender Flare using a 5/32” Allen key and a 3/8” wrench/socket. (wrench/socket and Allen key not supplied). Ensure inside of Fender Flares where the rubber seal is attached is clean, using the alcohol wipes provided. Wipe away any residue with a dry clean cloth.


STEP 2: Attach the included rubber seal to the Fender Flares. Peel back 2” of the adhesive backing and position on the Fender Flare. Attach the seal to the Fender Flare, peeling back a few inches at a time. Ensure pressure is used to secure rubber seal to Fender Flare edge. Attach rubber seal along all areas the Fender Flare will make contact with the vehicle body.


STEP 3: Trim any excess rubber seal and discard.


STEP 4: Clean the body areas where the Fender Flares will make contact. Ensure fenders are dry prior to install.


STEP 5: Place the Fender Flare on the vehicle into the position of best fit. Note where the slots in Fender Flare at positions A, B, C, and D align with the existing screws in the vehicle. Remove Fender Flare. Use the original manufacturer’s hardware that is in the wheel arch of the vehicle to fit the Fender flares. Remove the x4 9/32” (7mm) socket head screws from the fasteners on the vehicle.


STEP 6: Place the front Fender Flares onto the vehicle and line up the holes on the part with screw holes on the vehicle. Re-Install the socket head screws into the fender to secure the Fender Flares. Fit the Fender Flares loosely until the Fender Flares are aligned as desired, when satisfied tighten the screws fully to ensure rubber seal is flush neatly against the body.
