Designed for Volvo FM series trucks, the 84223840 Volvo Door Extension features precision-molded contours matching original cab geometry. The reinforced polymer construction maintains structural integrity during frequent door operations in urban delivery cycles.

UV-stabilized grey polypropylene resists color fading under intense sunlight exposure, while integrated mounting channels ensure seamless alignment with Volvo FM door assemblies. The modular design allows individual component replacement, reducing maintenance downtime for logistics fleets.

Ergonomic surface texture improves grip during manual adjustments, with corrosion-resistant fastening points that withstand road salt exposure. Aerodynamic profiling reduces wind noise at highway speeds, maintaining cabin acoustics for long-haul operations.
