Dongfeng KL truck parts Right door handle assembly 6102040-C3100

Built for effortless and consistent door operation, this handle assembly features an ergonomic design optimized for truck drivers. The grip surface is contoured to fit adult hands, with a 15° angle that reduces wrist strain when opening/closing the door—critical for frequent use during loading/unloading. The internal lever mechanism uses a high-strength nylon gear with 30° tooth engagement, requiring only 80N of operating force (30% less than aftermarket handles) while ensuring a secure connection to the door lock. A built-in return spring (stainless steel) provides consistent rebound force, preventing the handle from sagging and ensuring it resets to the closed position every time. The assembly supports 200,000+ opening cycles without failure, far exceeding the industry standard of 100,000 cycles

Engineered to withstand harsh outdoor conditions, the 6102040-C3100 handle features a fully weatherproof design. The outer shell is made of UV-stabilized ABS+PC alloy (UL94 V-0 grade) with a 2mm-thick wall, achieving IP67 protection—resisting dust ingress and water submersion up to 1m for 30 minutes. The internal linkage components are zinc-plated and powder-coated, passing 1500-hour neutral salt spray testing (ASTM B117) with no rust. A foam rubber gasket lines the handle’s base, forming a tight seal with the door panel to block rainwater and road salt from entering the door interior (preventing lock mechanism corrosion, repair cost up to $400). The handle operates reliably in temperatures from -40℃ to 85℃, adapting to frigid winters and sun-exposed door surfaces

Optimized to combine durability and security, the handle assembly integrates impact-resistant and anti-theft features. The ABS+PC shell achieves an impact resistance of 18kJ/m², capable of withstanding accidental collisions with cargo or tools without cracking—protecting the internal lock linkage. The handle’s connection to the lock uses a unique torque-limiting pin that prevents forced entry attempts: if the handle is pried, the pin breaks to isolate the lock mechanism, deterring theft of on-board items. The lever mechanism is also designed to be tamper-proof, with no external access points for picking tools. These features comply with automotive anti-theft standards (ISO 15408), enhancing cab security for parked trucks

This right door handle assembly is designed for efficient installation and long-term cost savings for Dongfeng KL operators. The pre-assembled structure (handle + linkage + mounting hardware) allows a single technician to complete replacement in 45 minutes using only a screwdriver and socket wrench—no specialized door disassembly tools needed. The OE-compatible design ensures perfect alignment with the door lock and outer panel, avoiding the misfit issues of aftermarket handles that cause door jamming or water leakage. The durable materials and corrosion-resistant coating extend service life to ≥400,000km—twice that of non-OE alternatives—reducing replacement frequency. Backed by a 2-year/250,000km Dongfeng warranty, it provides reliable door operation and predictable maintenance expenses, minimizing downtime for fleet vehicles
