Dongfeng GX Front suspension process assembly 5001910-GX200

Tailored exclusively for Dongfeng GX models, this assembly matches OEM dimensions with ±0.1mm tolerance, ensuring perfect alignment with the vehicle’s chassis and front-end components. The control arm’s 4 mounting holes (14mm diameter) align exactly with the subframe, and the ball joint’s spline size (24mm) matches the steering knuckle—no drilling or adapter needed. The assembly’s bushing positions (3 polyurethane bushings) follow the factory layout, ensuring proper suspension geometry (camber: ±0.5°, toe: ±0.2°) to maintain straight-line driving. Unlike generic aftermarket assemblies, it fits flush with the subframe and bumper, avoiding interference with brake lines or steering rods. It undergoes 250+ fitment tests on Dongfeng GX test vehicles, guaranteeing consistency. For repair shops and owners, this means a hassle-free replacement that preserves the vehicle’s original handling characteristics

The assembly features an optimized damping system to absorb road vibrations and enhance ride comfort. It includes a twin-tube shock absorber with a 32mm piston diameter, delivering adjustable damping force (500–1,200 N·s/m) to adapt to different road conditions—softening impacts on rough roads and stiffening for stable highway driving. The shock absorber’s oil (high-viscosity index hydraulic oil) maintains viscosity across -40°C to 80°C, ensuring consistent performance in extreme weather. The polyurethane bushings (hardness 80 Shore A) reduce vibration transmission to the cabin by 40% compared to rubber bushings, minimizing road noise at 60–100km/h. Tested on a vibration test bench (10–500Hz), it effectively filters out 90% of small road bumps, providing a smooth ride while maintaining suspension responsiveness for emergency maneuvers

Built for long-term durability, the assembly uses multi-layer protection against corrosion and wear. The control arm and sway bar undergo hot-dip galvanization (zinc coating thickness 10–15μm) followed by electrophoretic paint (20–25μm) and powder coating (hardness 2H), achieving 1,000-hour salt spray resistance (equivalent to 8+ years of coastal use) without rust. The ball joint features a chrome-plated stud (thickness 0.05mm) and low-friction PTFE (polytetrafluoroethylene) liner, reducing wear and extending service life to 80,000km. The shock absorber’s cylinder is made of seamless steel with a nickel-plated surface, resisting scratches from stones or debris. It also passes temperature cycling tests (-40°C to 85°C), ensuring no component failure from thermal expansion or contraction. For owners, this durability means minimal maintenance and no frequent replacements

Designed for easy installation, the assembly requires no specialized tools—using standard 19mm and 22mm wrenches, and a torque wrench (factory-specified torque: 90±5 N·m for control arm bolts). The process takes 45 minutes max: 1) Jack up the Dongfeng GX and secure it on stands; 2) Remove the old assembly by disconnecting the sway bar link, ball joint, and control arm bolts; 3) Align the new assembly with the subframe and steering knuckle (use factory alignment marks); 4) Tighten bolts to specified torque and reconnect the sway bar link. No suspension calibration is needed—though a wheel alignment is recommended post-installation for optimal performance. The assembly includes a detailed instruction manual with step-by-step diagrams. For repair shops, this reduces labor time; for DIY owners, it simplifies replacement, ensuring the suspension system is restored safely and efficiently
