Dongfeng KL truck parts Luggage box on the left and right sides of the sleeper 5402030029-C3350

Built to address the diverse storage demands of long-haul drivers, this luggage box features a spacious, well-organized design. Each box offers a 83L capacity (total 166L for left+right set), easily accommodating clothing, bedding, personal hygiene items, and tools. The internal structure includes a removable plastic divider (adjustable in 3 positions) that splits the main compartment into two zones, preventing items from mixing or shifting during driving. A dedicated mesh pocket (180×120mm) on the inner door stores small essentials like mobile phones and chargers for quick access, while a 50mm-deep tray at the bottom holds shoes or dirty items, isolating them from clean belongings. The box door opens to a 110° angle, providing full access to the interior without blocking the sleeper aisle

Engineered for long-term reliability under frequent use and cab vibration, the 5402030029-C3350 box is constructed from high-performance PP+GF20 (polypropylene with 20% glass fiber reinforcement). The 4mm-thick body achieves a tensile strength of 50MPa and impact resistance of 16kJ/m², resisting cracks from accidental impacts (e.g., dropping a tool inside) or rough handling. The material is heat-stabilized, maintaining structural integrity in temperatures ranging from -40℃ to 85℃—adapting to frigid winters and sun-exposed sleeper areas. The outer surface features a matte finish that hides minor scratches, while the inner surface is smooth and easy to clean—stains from dirt or spills can be wiped off with a damp cloth, ensuring hygiene for long-haul stays

Optimized to eliminate noise and ensure secure storage, the luggage box integrates reliable closure and anti-rattle mechanisms. It adopts a push-to-open latch with a built-in rubber buffer, which reduces closing noise to ≤30dB (quieter than a library environment) and ensures a tight seal. The latch’s spring-loaded design prevents the door from popping open during rough road conditions or sudden stops, even when fully loaded. A foam rubber gasket lines the door’s edge, creating a snug fit with the box body and blocking dust ingress, while also absorbing vibration from the cab (10-500Hz) to eliminate rattling during sleep. The hinge is made of galvanized steel with a nylon bushing, enabling 100,000+ opening/closing cycles without squeaking

This sleeper-side luggage box is designed for efficient installation and long-term cost savings for Dongfeng KL operators. The pre-assembled snap-fit clips and adhesive backing allow a single technician to install both left and right boxes in 60 minutes—no drilling or welding required. The OE-compatible design ensures perfect alignment with the sleeper’s interior trim, avoiding the mismatched gaps common with aftermarket boxes that compromise cab aesthetics and waste space. The durable material reduces replacement frequency, with a service life twice that of non-OE alternatives. By providing organized storage, it reduces driver stress (time spent searching for items) and minimizes the risk of lost personal belongings. Backed by a 2-year/250,000km Dongfeng warranty, it offers reliable storage solutions and predictable maintenance expenses for fleet operations
