Dongfeng GX left rear suspension Airbag shock absorber assembly 5001180-C6207

Tailored exclusively for Dongfeng GX’s left rear suspension, this assembly matches OEM dimensions with ±0.1mm tolerance. The top mounting bracket (powder-coated steel) has 2 pre-drilled holes aligning with the vehicle’s 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 the vehicle’s straight-line stability. Rigorously tested on Dongfeng GX test vehicles, it passes 180+ fitment checks to guarantee consistency, avoiding issues like misaligned airbags or restricted shock movement that could compromise handling

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 or pollution. The shock absorber’s cylinder is seamless steel with a chrome-plated surface (hardness 58 HRC), shielding against stone chips or debris. The internal piston seal (PTFE-coated nitrile) ensures leak-free operation from -40°C to 85°C (temperature cycling tested 500 times). The mounting hardware (stainless steel bolts) has 600-hour salt spray resistance, resisting rust in coastal or snowy areas. The airbag’s burst pressure rating (18 bar, 4× working pressure) ensures safety during sudden pressure spikes. For owners, this durability means reliable performance in rain, snow, or off-road conditions, reducing replacement frequency

The assembly supports 40–70mm of left rear suspension height adjustment, controlled via Dongfeng GX’s air suspension system. Raising the height (to 70mm) increases ground clearance for rough terrain or speed bumps, preventing rear underbody damage. Lowering it (to 40mm) improves aerodynamics at highway speeds, reducing wind resistance and fuel consumption by 4%. The height adjustment is precise (±1.5mm) and responsive (adjusts in 2.5 seconds), with the airbag maintaining pressure even under full rear load. This function also aids in vehicle leveling—if the left rear is loaded unevenly, the system inflates the airbag to match the right side, ensuring balanced tire contact and stable braking. Tested under varying loads, it maintains height accuracy, avoiding uneven sag that could cause steering drift

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