Dongfeng GX rear suspension Airbag shock absorber assembly 5001180-C6100

Tailored exclusively for Dongfeng GX, this assembly matches OEM dimensions with ±0.1mm tolerance. The top mounting bracket (powder-coated steel) has 2 pre-drilled holes aligning with the rear frame, and the bottom eyelet (18mm inner diameter) fits the rear axle’s shock mount without adapters. The air inlet port (1/8-inch NPT thread) connects directly to Dongfeng GX’s air suspension control system, requiring no custom hoses. Unlike generic air shocks, it follows the original rear suspension geometry (toe: ±0.3°, camber: -0.5°±0.2°), preserving straight-line stability. Rigorously tested on Dongfeng GX test vehicles, it passes 180+ fitment checks to avoid misaligned airbags or restricted movement, ensuring the rear suspension operates in sync with the front

Built to withstand harsh conditions, the assembly uses premium protective materials. The airbag’s EPDM rubber resists UV damage (3,500 hours of xenon arc testing) and ozone degradation, preventing cracking or air leakage in sunlight. The shock absorber’s cylinder is seamless steel with a chrome-plated surface (hardness 58 HRC), shielding against stone chips. The internal piston seal (PTFE-coated nitrile) ensures leak-free operation from -40°C to 85°C (500 temperature cycles). The mounting hardware (stainless steel bolts) has 600-hour salt spray resistance, resisting rust in coastal or snowy areas. The airbag’s 18-bar burst pressure rating (4× working pressure) ensures safety during sudden spikes. For owners, this durability means reliable performance in rain, snow, or off-road conditions, reducing replacements

The assembly supports 40–70mm of rear suspension height adjustment, controlled via Dongfeng GX’s air suspension system. Raising to 70mm increases ground clearance for rough terrain or speed bumps, preventing underbody damage. Lowering to 40mm improves aerodynamics at highways, cutting wind resistance and fuel consumption by 4%. Adjustment is precise (±1.5mm) and responsive (2.5 seconds), with the airbag maintaining pressure under full load. It also levels the vehicle—if the rear is unevenly loaded, the system inflates the airbag to match the front, ensuring balanced tire contact and stable braking. Tested under varying loads, it maintains height accuracy, avoiding sag that causes steering drift or uneven tire wear

Designed for easy installation, the assembly requires no specialized tools beyond 17mm/19mm wrenches and a torque wrench (80±5 N·m for top bolts). The process takes 40 minutes: 1) Jack up Dongfeng GX’s rear and secure it; 2) Disconnect the air line and electrical connector (if equipped); 3) Remove top bracket bolts and bottom eyelet pin; 4) Align the new assembly, tighten bolts, and reconnect components; 5) Calibrate via the vehicle’s on-board computer (simple menu selection). No cutting or welding is needed, and a step-by-step manual with diagrams is included. For repair shops, this reduces labor time; for DIY owners, it simplifies replacement, ensuring the rear suspension resumes optimal performance quickly
