Dongfeng VR truck parts Left lock assembly mask 5301609-C1100

Designed to serve both protective and decorative purposes, the mask safeguards the left lock assembly while elevating the door’s visual coherence. Functionally, it acts as a physical barrier for the lock’s internal components (cylinder, linkage, wiring) against road debris (dust, sand), water splashes, and accidental impacts (e.g., tool bumps during loading). Testing shows it reduces lock contamination by 80%—preventing jamming caused by dust accumulation and extending the lock’s service life by 50%. Aesthetically, it features a textured finish that matches the VR’s factory door panel material (soft-touch plastic or matte plastic), hiding minor scratches on the door panel around the lock and creating a unified, professional look. Unlike basic lock covers that only hide the lock, this dual-function design balances practical protection with visual refinement

Built to withstand daily wear, accidental impacts, and temperature fluctuations, the lock mask is crafted from a high-performance ABS+PC composite material. This blend combines the rigidity of ABS (acrylonitrile butadiene styrene) with the impact resistance of PC (polycarbonate), delivering a notched Izod impact strength of 18 kJ/m²—ensuring it won’t crack when struck by tools or debris. It also tolerates extreme temperatures from -30°C to 90°C, maintaining shape in cold winter garages or hot summer sunlight without warping. The material’s smooth surface resists scratches from keys or frequent contact, retaining its appearance even after 30,000+ lock operations (equivalent to 8 years of daily use). Unlike brittle PP plastic masks that break easily, this ABS+PC design ensures long-term durability in high-use scenarios

Engineered to resist degradation from moisture, road salt, and UV exposure (critical for door-mounted components), the mask undergoes comprehensive protective treatment. The composite material is infused with UV-stabilizers during manufacturing, preventing color fading and material brittleness even after 2,500 hours of direct sunlight exposure. A water-repellent coating (15μm thickness) is applied to the outer surface, causing rainwater to bead and run off—preventing water from seeping into the lock assembly and causing internal rust or electrical short circuits (for power locks). All metal mounting hardware (2 M4×10mm screws) are zinc-plated, resisting rust and ensuring secure attachment to the door panel even in snowy or coastal environments. Unlike unprotected masks that degrade quickly, this weatherproof design maintains functionality and appearance in all climates

Designed for hassle-free replacement by fleet technicians or DIY owners, the mask features a user-friendly installation system and low-maintenance requirements. Installation takes 8–12 minutes: align the mask’s lock hole cutout with the VR’s lock cylinder, secure it to the door panel using the included zinc-plated screws (a standard Phillips screwdriver is the only tool needed), and verify lock operation. The mask’s snap-fit design around the lock hole ensures a tight seal without additional gaskets, reducing dust intrusion. Maintenance is minimal: the smooth surface can be cleaned with a damp cloth to remove dust or grime, and the material resists staining from oil or cleaning agents. If damaged, it can be easily removed and replaced without affecting the lock assembly. Each unit undergoes fitment testing, impact resistance checks, and weatherproof verification, backed by a 18-month warranty against defects (e.g., cracking, fading, screw rust)
