20529478 Volvo Step Housing FMX-Series Solution

Engineered for precise alignment with VOLVO FM/FH/FMX chassis systems, the 20529478 Volvo Step Housing and its paired 3175159 variant deliver zinc-aluminum alloy protection for 1998-2021 models. Featuring 1.2mm thick galvanized steel (ZMA 320g/m²), this solution addresses FM7/FM10/FM12 step housing corrosion in coastal environments. The modular design maintains structural integrity across FMX mining trucks and FH long-haul configurations with D7-D16 engine types.

Technical Specifications

Constructed from HX420LAD+Z steel substrate, each 20529478 unit features 1.5mm thickness with laser-cut mounting holes. The 7-stage coating process includes zinc-iron alloy electroplating and epoxy powder coating. Alignment slots at 150mm intervals ensure proper fitment with VOLVO FM Series 1-3 cabs. 3175159 variant mirrors these specs with right-side configuration for FMX vocational models.
