Manufactured from handlaid fiberglass materials. Comes in grey primer, will require further sanding before primer and painting (arches come in textured dark grey primer). Side Skirts will only fit the SHORT WHEEL BASE models and come in 4 Pieces. Your bodyshop will need to create metal Z brackets to hold the underside of the side skirts against the body of the vehicle. Professional installation required from experienced bodykit installers and not DIY installation.
