84203734 Volvo Bracket | Precision Mounting Platform
84203734 Volvo Bracket
Engineered for VOLVO's F-Series heavy-duty platforms, the 84203734 Volvo Bracket (84203734, 84203735) combines UV-stabilized polymer construction with precision alignment for headlamp assemblies. The glass-fiber reinforced polyamide structure maintains dimensional stability across -30°C to +85°C operational ranges. Injection-molded mounting points replicate OEM fastener positions within ±0.3mm tolerance, while the anti-vibration clips reduce harmonic resonance by 42% compared to standard brackets. The matte black surface treatment resists chemical degradation from road salts and achieves 93% light absorption to prevent glare. Pre-installed cable routing channels maintain original wiring harness paths, and the modular design allows independent replacement of left/right components without full assembly disassembly.
Model-Specific Adaptation
Designed for VOLVO FM/FH Series trucks (2011 onward), these brackets accommodate both LED and xenon headlamp configurations. The 84203734 (left) and 84203735 (right) components feature mirror-imaged alignment pins that prevent incorrect installation. Six M8 threaded inserts maintain factory torque specifications of 22Nm ±10%, while the integrated drainage channels prevent water pooling in the lamp housing. The thermal expansion coefficient matches original VOLVO components (8.3×10⁻⁵/°C), eliminating stress fractures during temperature fluctuations. Pre-marked drilling guides allow seamless integration of auxiliary lighting accessories while maintaining structural integrity.
Manufacturing Precision
| Feature | Detail |
|---|---|
| Core Material | 30% glass-filled polyamide 6.6 |
| Surface Treatment | Electrostatic powder coating (RAL 9005) |
Utilizing 650-ton injection molding presses, the brackets achieve 0.02mm/mm flatness across all mounting surfaces. The snap-fit design reduces installation time by 35% compared to threaded fastener systems, while the color-stable polymer maintains 95% of original hue after 5,000 hours of UV exposure testing. The internal reinforcement ribs increase torsional rigidity by 28% without added weight, and the chemical-resistant formulation withstands diesel fuel splashes and alkaline cleaners. All edges feature radiused contours meeting ECE R45 debris protection standards, and the pre-installed rubber isolators dampen high-frequency vibrations from engine compartments.
