Dongfeng GX Secondary lock bracket assembly 5301602-C6200

Exclusively engineered for Dongfeng GX commercial vehicles (including heavy-duty trucks and light cargo models), this bracket assembly strictly complies with the original equipment (OE) specifications of part number 5301602-C6200. It is manufactured using 3D laser scanning and CNC precision stamping, achieving dimensional accuracy within ±0.2mm—seamlessly aligning with the Dongfeng GX’s body frame, secondary lock assembly, and pre-drilled mounting points. The bracket includes 7 M8-threaded mounting holes (12mm depth) and 2 positioning pins that perfectly match the vehicle’s body interface, allowing direct installation without on-site drilling, trimming, or modification. It is fully compatible with all Dongfeng GX models produced since 2022, making it an ideal replacement part for factory assembly or after-sales repairs, and avoiding compatibility issues common with generic alternatives

To withstand the harsh under-vehicle or exterior conditions (rain, road salt, humidity, industrial dust) that commercial vehicles face, the 5301602-C6200 bracket undergoes a multi-layer anti-corrosion treatment. The process begins with zinc phosphate pretreatment (9-11μm thick) to enhance coating adhesion, followed by an electrophoretic primer (16-22μm thick) for uniform corrosion resistance. The final layer is a high-durability polyester powder coating (65-85μm thick) in black (matching the Dongfeng GX’s underbody aesthetics), which meets ISO 10289 standards. It passes 1200-hour neutral salt spray tests without red rust or coating peeling, ensuring the bracket maintains structural integrity and appearance for over 9 years—even in coastal or high-salt regions—reducing long-term maintenance and replacement costs

Beyond acting as a mounting base, the bracket assembly is designed to optimize the secondary lock’s safety performance. It features a precision-machined lock engagement slot with a tolerance of ±0.08mm, ensuring the lock’s striker or bolt aligns perfectly with the bracket to prevent jamming or partial engagement (a common cause of lock failure). The bracket also includes an anti-loosening structure: a serrated washer interface on the mounting plate that increases friction between the bracket and body frame, preventing bolt loosening from prolonged vibration (a key issue in commercial vehicle operation). Additionally, all edges are deburred and rounded (2.5mm radius) to avoid damaging the lock’s rubber seals or nearby wiring harnesses, further extending the entire lock system’s service life

The 5301602-C6200 bracket assembly prioritizes user-friendliness for installation and maintenance. It comes with a complete hardware kit, including 7 grade 8.8 high-strength bolts, serrated washers, and lock nuts—eliminating the need for separate part sourcing. The bracket’s compact dimensions (190mm × 130mm × 48mm) and clear laser-engraved alignment marks allow technicians to position it accurately in 8-12 minutes, cutting installation time by 55% compared to non-OE brackets. For maintenance, the smooth powder-coated surface can be cleaned with a damp cloth to remove dust or debris, and the robust structure requires no additional periodic checks beyond standard vehicle servicing. It also includes a 30-month warranty against material defects (e.g., coating peeling, structural cracking) and manufacturing errors, providing peace of mind for Dongfeng GX owners and repair facilities
