Dongfeng GX Right door upper hinge assembly 6101202-C6100

To maintain smooth door movement over time, the 6101202-C6100 hinge assembly integrates wear-resistant components and precision engineering. The pivot pin is chrome-plated (plating thickness: 10-12μm) to reduce friction and prevent metal-to-metal wear, while the hinge’s inner bushings are made of self-lubricating brass (CuZn39Pb3) that eliminates the need for periodic oiling. The bushing-pin interface has a clearance of only 0.05-0.1mm, ensuring tight yet smooth rotation—door opening/closing requires a force of just 8-12N, minimizing driver effort. Additionally, the hinge’s contact surfaces are polished to a smooth finish (Ra ≤ 0.4μm) to further reduce friction, and the assembly undergoes a 5,000-cycle wear test with no significant increase in operating force—guaranteeing smooth performance for over 8 years

Exposed to rain, road salt, and humidity, the 6101202-C6100 hinge assembly requires robust corrosion resistance to maintain functionality. It undergoes a multi-layer anti-corrosion treatment: first, a zinc phosphate pretreatment (8-10μm thick) for adhesion; second, an electrophoretic primer (15-20μm thick) for uniform coverage; and finally, a black epoxy powder coating (60-70μm thick) that meets ISO 10289 standards. This system passes 1000-hour neutral salt spray tests without red rust or coating peeling, protecting the hinge from corrosion in coastal, snowy, or industrial areas. The pivot pin’s chrome plating also provides additional corrosion resistance, ensuring it remains rust-free and operational even when exposed to moisture—extending the hinge’s service life to over 10 years

Exclusively tailored for Dongfeng GX commercial vehicles (including heavy-duty trucks and light cargo models), the 6101202-C6100 hinge assembly strictly adheres to original equipment (OE) specifications. Manufactured using CNC machining and precision forging, it achieves dimensional accuracy within ±0.05mm—perfectly aligning with the right door’s upper mounting points and the vehicle’s body frame. The hinge features 4 pre-drilled mounting holes (M8 threaded, 12mm depth) that match the Dongfeng GX’s factory hole positions, ensuring no gaps or misalignment after installation—this prevents door rattling, water leakage, or difficulty closing. It is fully compatible with all Dongfeng GX models produced since 2021, making it a direct replacement part for factory assembly or after-sales repairs—no modification to the door or body is required

The 6101202-C6100 hinge assembly is designed for hassle-free installation and minimal maintenance. It comes with a complete hardware kit, including 4 grade 10.9 high-strength bolts, lock washers, and anti-loosening nuts—eliminating the need for separate part sourcing. The hinge’s compact design (length: 85mm × width: 45mm × height: 30mm) and lightweight construction (0.8kg) allow two technicians to install it in 20-25 minutes, 30% faster than non-OE hinges. For maintenance, the self-lubricating brass bushings require no oiling, and the powder-coated surface can be cleaned with a damp cloth to remove dirt or debris. The assembly also includes a 30-month warranty against material defects (e.g., hinge cracking, pivot pin bending) and manufacturing errors, providing confidence for Dongfeng GX owners and repair facilities
