Dongfeng GX Right hydraulic lock bolt with sensor assembly 5002165-C6200

Equipped with a high-pressure hydraulic cylinder, this assembly ensures secure locking and smooth bolt movement for Dongfeng GX’s right-side components (e.g., sliding door or trunk). The hydraulic system operates at 8–12MPa, generating enough force to keep the bolt fully extended under vibration (tested to 200Hz) or external pressure (up to 500N), preventing accidental unlocking during driving. The bolt (made of high-strength carbon steel) has a 15mm extension length, ensuring deep engagement with the strike plate for maximum security. The hydraulic fluid (synthetic mineral oil) maintains viscosity across -40°C to 80°C, ensuring smooth operation in extreme temperatures—no stiffening in cold weather or leakage in heat. A built-in pressure relief valve prevents overloading, protecting the cylinder from damage if the bolt encounters obstruction

Engineered exclusively for Dongfeng GX models, this assembly matches OEM dimensions with ±0.2mm tolerance, ensuring perfect alignment with the vehicle’s right-side lock housing and strike plate. The mounting bracket (powder-coated steel) has 3 pre-drilled holes that align exactly with the Dongfeng GX’s frame, eliminating gaps that could cause noise or misalignment. The hydraulic cylinder’s port location and sensor’s position follow the factory layout, avoiding modifications to the vehicle’s structure or wiring. Unlike generic aftermarket locks, it fits flush with the surrounding components, preserving the vehicle’s original design. Rigorously tested on Dongfeng GX test vehicles, it passes 300+ fitment checks to guarantee consistency. For repair shops and owners, this means a hassle-free replacement that maintains locking functionality and avoids issues like stuck bolts or sensor misreadings

Constructed with rugged materials, the assembly is built to withstand long-term use and harsh conditions. The bolt uses S45C carbon steel (hardness HRC 35–40), resisting deformation even under repeated stress. The hydraulic cylinder’s inner wall is chrome-plated (thickness 0.05mm), reducing friction and preventing internal wear. The mounting bracket and sensor housing are coated with electrophoretic paint, providing salt spray resistance for 500 hours (equivalent to 5 years of coastal use) without rust. The hydraulic seals (nitrile rubber) are oil-resistant and temperature-stable, preventing fluid leakage over 80,000 cycles. It also passes impact tests (1.5m drop onto concrete) to ensure the sensor and cylinder remain intact after accidental bumps. For owners, this durability means minimal maintenance and no frequent replacements, reducing long-term costs while ensuring reliable locking performance

The 5002165-C6200 assembly is fully compatible with Dongfeng GX’s safety and control systems, enhancing overall vehicle safety. The sensor’s lock status signal triggers critical functions: if the bolt is unlocked while driving (≥10km/h), the ECU activates an audible warning and dashboard alert to remind the driver. It also disables the power sliding door (if equipped) when the vehicle is in motion, preventing accidental door opening. The hydraulic lock’s secure engagement meets FMVSS 206 standards for door lock strength, ensuring it holds the door closed during a collision. The assembly’s electrical system complies with ISO 16750 for automotive electronics, avoiding interference with other components (e.g., ABS, airbags). Each unit undergoes system integration tests on Dongfeng GX platforms to ensure seamless communication with the vehicle’s ECU, guaranteeing that safety features work as intended
