Design & Manufacturing Philosophy

STILLEN roof wings are the result of decades of hands-on design and manufacturing expertise. Each application begins with hand-shaped master parts that are carefully measured and matched to the vehicle. These masters are then used to create molds for in-house polyurethane production, ensuring consistent quality and precise fitment every time.

STILLEN’s proprietary polyurethane formulation delivers the perfect balance of strength, flexibility, and surface finish—allowing each roof wing to perform and look great for years to come. This meticulous process gives STILLEN the confidence to back every body styling product with a limited lifetime warranty.
