Dongfeng GX truck parts right pneumatic strut Upper bracket assembly 5301630-C6200

Built as the core load-bearing component for the right pneumatic strut, this bracket features a robust design to withstand dynamic and static forces. The main body is fabricated from Q690 high-strength steel via precision forging, with a 10mm-thick base and 8mm-thick reinforcing ribs—achieving a static load capacity of 8000N, easily supporting the pneumatic strut’s extension force (up to 6000N) when lifting the cab or hood. The bracket’s triangular rib structure optimizes force distribution, reducing deflection to ≤0.8mm under maximum load and preventing the strut from shifting. It passes 50,000-cycle fatigue testing (simulating 5 years of cab tilting operations) without structural deformation, ensuring stable support even in frequent use scenarios

Engineered to resist corrosion and wear in the harsh outdoor conditions of truck operation, the 5301630-C6200 bracket adopts an advanced multi-layer protective coating system. The entire component undergoes shot blasting (Sa 2.5 grade) to remove surface impurities, followed by a cathodic electrophoretic primer (40μm thickness) for uniform rust prevention. The top layer is a ceramic-rich powder coating (50μm thickness) with exceptional wear resistance, passing 5000-cycle abrasion testing (ASTM D4060) without coating damage. This system achieves 2500-hour neutral salt spray resistance (ASTM B117) with no rust, adapting to coastal regions, snowy areas (road salt exposure), and construction sites with high humidity

Optimized to eliminate noise and prevent loosening caused by vehicle vibration, the bracket integrates dedicated dampening and anti-loose features. It includes a rubber bushing (EPDM material, 5mm thickness) between the bracket and pneumatic strut ball joint, absorbing vibration from the truck’s chassis (10-500Hz) and preventing metal-to-metal contact that causes rattling. The bolt holes are equipped with flange nuts with nylon inserts (self-locking design) that prevent loosening even after 100,000km of operation, avoiding the need for periodic re-tightening. A grease fitting is integrated into the bracket’s ball joint interface, allowing easy lubrication to reduce friction and extend the strut’s service life by 30%

This pneumatic strut upper bracket is designed for efficient installation and long-term cost savings for Dongfeng GX operators. The pre-assembled structure (bracket + bushing + self-locking nuts + grease fitting) allows a single technician to complete replacement in 45 minutes using only a socket wrench and torque meter—no welding or drilling required. The OE-compatible design ensures perfect alignment with the pneumatic strut and cab frame, avoiding the misfit issues of aftermarket brackets that cause strut failure or cab/hood misalignment (repair costs up to $1,200). The high-strength steel and corrosion-resistant coating extend the bracket’s service life to ≥800,000km—twice that of non-OE alternatives. Backed by a 3-year/500,000km Dongfeng warranty, it provides reliable support and predictable maintenance expenses for fleet operations
