The Duraflex 100471 GT Competition Rear Lip Under Spoiler Air Dam is a single-piece aerodynamic add-on designed to give your vehicle an aggressive, competition-inspired stance. Built by Extreme Dimensions under the Duraflex brand, this rear lip integrates cleanly beneath the rear bumper to enhance visual flow and complement a sport or body kit build.

Duraflex components are constructed from FRP (Fiberglass Reinforced Plastics) — an innovative blend of fiberglass, plastic, and flex resins that delivers a unique combination of strength and flexibility. This proprietary material formulation results in significantly higher durability than traditional fiberglass, reducing shipping and handling damage by up to 75%.

Key Features:

• Hand-laid, high-quality 6 oz. fiberglass construction
• Proprietary polymer blend for maximum flexibility and resilience
• Signature black primer finish — ready for prep and paint
• Aerodynamic GT Competition styling for an aggressive rear profile
• Reduced damage rate up to 75% compared to standard fiberglass
• 1-piece design for streamlined installation
• Also sold as part of the GT Competition Body Kit (pairs with front bumper cover 100470 and side skirts 100472)

Installation Notes: Professional installation by a licensed automotive body shop is strongly recommended. As with all FRP fiberglass parts, dry fitting is required before drilling mounting holes. Some bodywork, filling, and modification may be necessary prior to priming and painting. Mounting hardware and instructions are not included.
