Dongfeng GX Pneumatic strut assembly 5301626-C6201 for sale

The part number 5301626-C6201 is a unique official identifier authorized by Dongfeng, distinguishing this genuine pneumatic strut from counterfeit or substandard alternatives. By entering this number into Dongfeng’s official parts database, users gain access to comprehensive details: production batch, manufacturing date, quality inspection reports (e.g., pressure retention and fatigue tests), and authorized supply channels—enabling full lifecycle traceability. This traceability is critical for safety: if the strut experiences pressure loss or structural failure, the part number facilitates quick tracking of production defects to prevent hazards (e.g., sudden cover/trunk collapse). For workshops, it streamlines inventory management and procurement, ensuring accurate selection of GX-specific units. The number is laser-etched on the strut’s cylinder body, remaining legible despite long-term exposure to dust, moisture, and temperature changes, enabling easy authenticity checks

As a core lifting component, this strut assembly delivers consistent, reliable pneumatic support for the Dongfeng GX’s front cover or trunk. It features a high-pressure nitrogen gas chamber (working pressure: 9-11MPa) calibrated to the vehicle’s access point weight (typically 320-520N), enabling one-handed opening and keeping the cover/trunk fully extended without additional props. The precision-machined piston rod (surface roughness Ra ≤0.8μm) ensures smooth, silent operation—no creaking or jitter during extension/retraction. A built-in pressure relief valve prevents over-pressurization, enhancing safety. Tested under 12,000+ extension-retraction cycles (simulating 6 years of daily use) and extreme conditions (-35°C to 85°C), the strut maintains stable pressure retention (loss ≤4% annually) and consistent lifting force. This ensures safe, unobstructed access to the engine compartment or trunk, even in harsh weather

To withstand frequent use and harsh environments, this pneumatic strut uses premium materials and anti-leakage technology. The cylinder body is crafted from seamless aluminum alloy (6063-T5) with an anodized coating (thickness ≥20μm), providing exceptional corrosion resistance against rain, road salt, and humidity. The piston rod is made of chrome-plated high-carbon steel (HRC 52-56), resisting wear and bending. The seal system combines high-temperature-resistant fluororubber (FKM) O-rings and PTFE scraper rings, preventing gas leakage and blocking dust/debris from entering the cylinder. Every unit undergoes 100% quality testing: 48-hour pressure retention checks, burst pressure tests (18MPa), and 1000-hour salt spray tests. This rigorous engineering ensures no leakage or structural failure, guaranteeing a service life of 7-9 years—matching the vehicle’s expected lifespan

Designed for user convenience, this strut assembly features tool-free installation with no specialized equipment required. It adopts Dongfeng GX’s original snap-in end fittings: align the strut’s ball sockets with the vehicle’s mounting pins, press until a “click” confirms secure attachment, and remove the old strut by releasing locking clips. No drilling, welding, or bracket adjustments are needed, and replacement takes 8-12 minutes per strut—even for non-professionals. Clear “UP” direction markers prevent reverse installation, and a concise, bilingual (English/Chinese) guide is included in the packaging. Unlike non-OE struts that require fitting modifications, this assembly saves time and labor, ensuring the strut operates in perfect sync with the vehicle’s access point, maintaining safe, stable support long-term
