Extreme Dimensions revolutionized the fiberglass market with our line of Duraflex aerodynamics. Duraflex combines fiberglass, plastic, and flex resins to obtain its unique features. Because of these features, Duraflex aero parts obtain a much higher durability rate than the average fiberglass product, resulting in reduced shipping damages up to 75%. Not a direct bolt-on item: requires professional installation by a body shop with extensive experience in working with aftermarket fiberglass and polyurethane parts. Please note that Duraflex parts are NOT primed nor ready for paint. These parts may require custom fitting, drilling, sanding, trimming, filling gaps, or other modifications.
