Duraflex 103637 GT Concept Style Rear Bumper Cover Fiberglass 1-Piece

The Duraflex 103637 GT Concept Rear Bumper Cover is a one-piece fiberglass rear bumper designed to deliver an aggressive, aerodynamic styling upgrade. Part of the GT Concept series — developed exclusively by Extreme Dimensions' in-house design team — this bumper cover is engineered to complement the vehicle's factory body lines while giving it a distinctly custom look.

Key Features:

• Hand-laid, high-quality 6 oz. fiberglass construction for a lightweight yet durable build
• Proprietary Duraflex composite technology — a blend of fiberglass, plastic, and flex resins — provides significantly greater durability and flexibility compared to standard fiberglass, reducing the risk of cracking on impact
• Aerodynamic GT Concept styling designed to enhance the vehicle's rear profile and visual stance
• Paintable surface — arrives raw and unfinished with a rough black protective coating, ready for professional prep, prime, and paint to match your vehicle's color
• 1-piece design for clean fitment and easier installation
• Compatible with the full GT Concept body kit lineup, which includes matching front bumper (103635) and side skirts/rocker panels (103636)

Installation Notes:

• Parts arrive raw and unpainted — sanding, body work, and fine-tuning are required before priming and painting
• Professional installation by an experienced auto body shop familiar with custom fiberglass work is strongly recommended
• Always dry-fit and test-fit the part before drilling mounting holes or applying paint
• Mounting hardware is not included; factory OEM fasteners or custom hardware may be required
• Minor waves or pinholes in raw fiberglass are normal and will be addressed during professional body prep

The Duraflex 103637 GT Concept Rear Bumper Cover is the ideal choice for enthusiasts looking to achieve a cohesive, aggressive custom build at an accessible price point.
