PRODUCT DESCRIPTION
Genuine High-Strength Steel & Anti-Corrosion Design
This front roof mounting beam (OE:5704920-C6100) adheres to Dongfeng’s genuine standards, crafted from 5mm high-strength steel (load capacity: 600kg) with black anti-corrosion electroplating. It undergoes ISO 9001 vibration durability testing, retaining structural integrity after 120,000+ km of rough-road use. Unlike aftermarket beams, its factory-welded reinforcing brackets reduce roof vibration by 85%—no loose mounts that damage cabin roof panels. The coating resists salt spray corrosion for 6+ years.
Perfect Compatibility & Unstable Roof Support
It is 100% compatible with Dongfeng GX&KX’s front cabin roof (cross-check OE 5704920-C6100 for fitment). The beam solves pain points: weak frames that bend under roof load, rust-prone materials, and misfit mounts that cause roof rattling. Per Dongfeng fleet data, it reduces roof-related maintenance by 95%, avoiding costly cabin roof damage. Pre-drilled holes match chassis mounts, cutting installation time by 40% vs. non-genuine parts.
Long-Lasting Durability & Safety Compliance
As a cabin structural component, this beam retains 98% load capacity after 5 years of use, with no steel fatigue. It meets Dongfeng’s safety standards: the reinforced structure prevents roof deformation during collisions, improving driver safety. It complies with commercial vehicle chassis strength regulations, ensuring safe operation in heavy-duty scenarios (e.g., off-road logistics).
Trusted Supplier & Hassle-Free Support
We are a direct Dongfeng genuine parts exporter with global shipping experience. The beam is packaged in heavy-duty foam + wooden crates to avoid damage. We offer a 24-month warranty against deformation or corrosion, and our 24/7 team provides roof mount alignment guidance.
