These aluminum fenders not only protect your rear wheel well compartment from dirt and debris but do it in style. Their proprietary process of stamping their logo not only adds an additional element of style not seen in the industry but also increases the rigidity of the whole inner fender. Note: While all precautions are made to ensure the aluminum surface is protected, small scratches from either the raw material from the factory, the manufacturing process, or the shipping process may be present in this unfinished product. They recommend you finish this product with either painting, powder coating or another similar process and prepare the surface prior to finishing as you would normally to remove any minor blemishes. Mounts to OEM holes on sub frame plus additional holes to be drilled. See instructions for hole locations to determine if modification will be necessary to install with aftermarket fenders. While aluminum is corrosion resistant, it is recommended to have some type of coating for long term corrosion protection.
