Dongfeng GX truck spare parts support 2701511-H11A0 in stocked

Built to bear the weight of air brake components and resist dynamic stresses, this support features exceptional structural rigidity. The main body is fabricated from Q550 high-strength steel via precision stamping, with a 7mm-thick base and 5mm-thick triangular reinforcing ribs—enhancing anti-bending strength by 50% compared to ordinary Q235 steel supports. It achieves a static load capacity of 250N, easily securing the 8kg air reservoir and withstanding vibration-induced forces during high-speed driving (up to 110km/h) or off-road operations. The stamping process optimizes material grain flow, ensuring the support endures 500,000km of road vibration without deformation or fatigue cracking

Engineered to resist harsh under-vehicle environments, the 2701511-H11A0 support adopts a multi-layer protective system. The entire steel structure undergoes Sa 2.5-grade shot blasting to remove rust and impurities, followed by a 40μm cathodic electrophoretic primer for uniform rust prevention. The top layer is a 50μm weather-resistant polyester powder coating, which achieves 2200-hour neutral salt spray resistance (ASTM B117) with no red rust—adapting to coastal humidity, road salt in winter, and muddy construction sites. The support’s edges are rounded (R5mm) to absorb gravel impacts (up to 55km/h) without denting, while welding joints are sealed with anti-corrosion mastic to block moisture ingress

Optimized to reduce vibration transmission and prevent component loosening, the support integrates dedicated dampening features. It includes 4mm-thick EPDM rubber gaskets between the support and air reservoir, as well as between the support and frame—absorbing 65% of chassis vibration (10-500Hz) and preventing metal-to-metal contact that causes noise. The mounting bolts use flange nuts with nylon inserts (self-locking torque ≥18N·m), which maintain tightness even after 100,000km of operation, avoiding the need for periodic re-tightening. A drainage groove at the support’s bottom prevents water accumulation, further reducing the risk of corrosion and extending service life

This support is designed for efficient installation and long-term cost savings for Dongfeng GX operators. The pre-assembled structure (support + rubber gaskets + grade 10.9 mounting bolts + lock washers) allows a single technician to complete replacement in 35 minutes using only a torque wrench (target torque: 120±10N·m)—no welding or drilling required. The OE-compatible design eliminates misalignment issues of aftermarket supports, which often cause air reservoir tilting or brake system leaks (repair costs up to $1,000). The high-strength steel and corrosion-resistant coating extend service life to ≥800,000km—twice that of non-OE alternatives. Backed by a 3-year/500,000km Dongfeng warranty, it ensures reliable component support and predictable maintenance expenses
