Dongfeng GX right front suspension Height valve assembly 5001090-C6104

The part number 5001090-C6104 is a unique official identifier authorized by Dongfeng, distinguishing this genuine height valve assembly from counterfeit or low-quality alternatives. By inputting this number into Dongfeng’s official parts database, users can access comprehensive details: production batch, manufacturing date, quality inspection records (e.g., pressure regulation accuracy and leak tests), and authorized supply channels—enabling full lifecycle traceability. This traceability is critical for safety: if the valve fails (e.g., unable to maintain suspension height), the part number helps track production defects to prevent hazards (e.g., unstable handling). For workshops, it simplifies inventory management and procurement, ensuring accurate selection of right-front-specific valves. The number is clearly etched on the valve’s housing using wear-resistant technology, remaining legible even after long-term exposure to road dust and moisture, facilitating easy authenticity checks

As a core suspension control component, this height valve assembly delivers accurate, real-time suspension height adjustment for the Dongfeng GX’s right front wheel. It uses a mechanical-hydraulic/pneumatic linkage system that monitors suspension movement (via a connecting rod to the control arm) and automatically adjusts air/hydraulic pressure in the suspension cylinder—maintaining the preset ride height (tolerance ±2mm) regardless of load changes (e.g., passenger or cargo weight). This prevents the vehicle from sagging under heavy loads or rising excessively when unloaded, ensuring consistent ground clearance (protecting undercarriage components) and stable handling (reducing body roll during cornering). The valve’s response time is ≤0.3 seconds, ensuring rapid adjustment to sudden road changes (e.g., potholes). Tested under simulated load cycles (0-100% of maximum front axle load) and extreme temperatures (-30°C to 80°C), it maintains precise height control, guaranteeing comfortable and safe driving

To withstand harsh road conditions (vibration, dust, and hydraulic/pneumatic pressure), this height valve assembly uses high-quality materials and anti-leakage technology. The valve body is made of high-strength aluminum alloy (6061-T6) with an anodized coating (thickness ≥15μm), resisting corrosion from road salt and moisture. Internal 阀芯 (valve core) is made of hardened stainless steel (304) with a polished surface (Ra ≤0.4μm), reducing friction and preventing wear. The seal system uses high-temperature-resistant nitrile rubber (NBR) O-rings and PTFE backup rings, ensuring zero leakage (pressure loss ≤0.1MPa/24h) even under maximum operating pressure (10-15MPa). The linkage rod is made of galvanized carbon steel, resisting rust and bending. Every unit undergoes 100% quality testing: pressure regulation accuracy tests, leak tests (under 1.5x maximum pressure), and vibration tests (10-500Hz), ensuring durability for 8-10 years (matching the vehicle’s suspension service life)

Designed for user convenience, this height valve assembly features easy installation and factory-calibrated settings that require no complex adjustments. It adopts the original Dongfeng GX’s mounting design: the valve’s base bolts directly to the suspension frame (using 3 standard M8 bolts), and the linkage rod connects to the control arm via a snap-in ball joint—no specialized tools needed. The valve comes pre-calibrated to the GX’s factory ride height, eliminating the need for on-site calibration (saving 1-2 hours of setup time). A bilingual (English/Chinese) installation manual is included, providing step-by-step instructions, diagrams of mounting positions, and precautions (e.g., ensuring linkage rod alignment before tightening bolts). Even novice maintenance personnel can complete installation in 30-40 minutes. Unlike non-OE valves that require professional calibration equipment, this assembly ensures immediate, accurate operation, maintaining the suspension’s original performance and safety
