84224253 Volvo Door Extension Technical Profile

The 84224253 Volvo Door Extension implements precision-engineered construction meeting 84224253/84223840 specifications through injection-molded polyamide geometry. The UV-stabilized material matrix incorporates glass-fiber reinforcement for enhanced structural integrity across FM/FH series cabs. Aerodynamic profiling reduces turbulence while maintaining 5.2mm clearance tolerances during full door operation cycles. Precisely aligned mounting points enable direct integration with original cab substructures, utilizing 84484360 fastener kits for OEM-compliant installation procedures. Dual-layer sealing channels prevent environmental ingress without compromising door panel movement parameters.
