Dongfeng GX Secondary lock bracket assembly 5301602-C6100

Exclusively tailored for Dongfeng GX series commercial vehicles (including heavy-duty trucks and light cargo models), this bracket assembly strictly adheres to the original equipment (OE) specifications of part number 5301602-C6100. It is manufactured using 3D laser scanning and CNC stamping technology, achieving dimensional accuracy within ±0.3mm—perfectly aligning with the Dongfeng GX’s body frame, lock assembly, and mounting points. The bracket includes 6 pre-drilled mounting holes (M8 threaded, with a depth of 12mm) and 2 locating pins that match the vehicle’s body interface, ensuring seamless integration without on-site drilling or trimming. 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, and eliminating compatibility issues common with non-OE alternatives

The 5301602-C6100 secondary lock bracket is treated with a multi-layer anti-corrosion coating to withstand harsh under-vehicle or exterior conditions (e.g., rain, road salt, humidity, and industrial dust). The process starts with a zinc phosphate pretreatment (8-10μm thick) to enhance coating adhesion, followed by an electrophoretic primer (15-20μm thick) that provides uniform corrosion resistance. The final layer is a high-gloss polyester powder coating (60-80μm thick) available in black (matching the Dongfeng GX’s underbody color scheme), which meets ISO 10289 standards for salt spray resistance—passing 1000-hour neutral salt spray tests without red rust or coating peeling. This protection ensures the bracket maintains structural integrity and appearance for over 8 years, even in coastal or high-salt regions, reducing maintenance and replacement costs

Beyond serving as a mounting base, the bracket assembly is engineered to enhance the secondary lock’s safety performance. It features a precision-machined lock engagement slot (with a tolerance of ±0.1mm) that ensures the secondary lock’s striker or bolt aligns perfectly with the bracket, preventing misalignment that could cause lock jamming or partial engagement. The bracket also includes a built-in anti-loosening structure: a serrated washer interface on the mounting plate that increases friction between the bracket and body frame, preventing bolt loosening from long-term vibration (common in commercial vehicle operation). Additionally, the bracket’s edges are deburred and rounded (radius of 2mm) to avoid damage to the lock’s rubber seals or wiring harnesses nearby, further ensuring the lock system’s long-term reliability

The 5301602-C6100 bracket assembly is designed for user-friendly installation and minimal maintenance. It comes with all necessary mounting hardware, including 6 high-strength bolts (grade 8.8), serrated washers, and lock nuts—eliminating the need for separate part sourcing. The bracket’s compact design (dimensions: 180mm × 120mm × 45mm) and clear alignment marks (engraved on the mounting plate) allow technicians to position it correctly in 10-15 minutes, reducing installation time by 50% compared to non-OE brackets. For maintenance, the powder coating’s smooth surface is easy to clean (simply wipe with a damp cloth to remove dust or debris), and the bracket’s robust structure requires no periodic inspections beyond standard vehicle maintenance. It also includes a 24-month warranty against material defects (e.g., coating failure, structural cracking) and manufacturing errors, providing confidence for Dongfeng GX owners and repair facilities
