Dongfeng GX truck parts Transmission control lever Bracket assembly C1703460-H02C0

As the core load-bearing component for the transmission control lever, this bracket features exceptional structural rigidity to maintain shift precision. The main body is fabricated from Q550 high-strength steel via robotized welding, with a 6mm-thick base and 5mm-thick triangular reinforcing ribs—boosting anti-torsion strength by 55% compared to standard steel brackets. It achieves a static load capacity of 250N, effectively resisting lateral and vertical forces during shift operations, limiting lever deflection to ≤0.5mm. This stability ensures accurate gear engagement, reducing shift error rate by 80% compared to loose aftermarket brackets. The welding joints undergo ultrasonic flaw detection, with no internal defects, ensuring durability under 500,000+ shift cycles

Optimized to eliminate shift noise and vibration, the bracket integrates dedicated dampening features. It includes 5mm-thick EPDM rubber gaskets between the bracket and cab floor, as well as between the bracket and control lever bushing—absorbing 70% of engine and chassis vibration (10-500Hz) and preventing metal-to-metal contact. The gaskets reduce shift operation noise to ≤40dB, eliminating the rattling sound common with unbuffered brackets. The lever mounting bushing, made of polyurethane (Shore A 85 hardness), provides smooth rotational resistance (0.8-1.2N·m), ensuring precise and comfortable shifting without excessive looseness. The mounting bolts use flange nuts with nylon inserts (self-locking torque ≥18N·m), preventing loosening after long-term use

Engineered for long-term reliability in the truck cab environment, the C1703460-H02C0 assembly adopts a robust protective system. The steel structure undergoes shot blasting (Sa 2.5 grade) to remove impurities, followed by a 30μm cathodic electrophoretic primer and 40μm matte black powder coating. This dual-layer finish achieves 1500-hour neutral salt spray resistance (ASTM B117) with no rust, resisting corrosion from sweat, oil stains, and cleaning agents. The lever contact surface is coated with molybdenum disulfide (MoS₂) for solid lubrication, reducing friction and wear between the bracket and lever bushing. The powder coating has a scratch resistance of ≥2H, maintaining a neat appearance even with frequent contact

This transmission control lever bracket is designed for efficient installation and long-term cost savings for Dongfeng GX operators. The pre-assembled structure (bracket + rubber gaskets + mounting bolts + lock nuts) allows a single technician to complete replacement in 30 minutes using only a torque wrench (target torque: 110±8N·m)—no welding or drilling required. The OE-compatible design eliminates alignment issues of aftermarket brackets, which often cause shift inaccuracies or transmission damage (repair costs up to $1,200). The high-strength steel and durable components extend service life to ≥800,000km—twice that of non-OE alternatives. Backed by a 2-year/300,000km Dongfeng warranty, it ensures precise shift control and predictable maintenance expenses for fleets
