Dongfeng KL truck parts Right door sill pressure strip assembly 5102010-C3100

Designed to protect the high-wear right door sill and enhance cab sealing, the assembly integrates two core functions. As a protective barrier, it shields the underlying metal sill from scratches, dents, and impact damage caused by boots, tools, or cargo during driver/passenger entry/exit—reducing sill repair costs by 70% compared to unprotected sills. As a sealing component, the strip’s edge features a soft TPE (thermoplastic elastomer) seal (60±5 Shore A hardness) that compresses against the door when closed, blocking 90% of dust, rainwater, and road noise from entering the cab. Unlike basic plastic strips that only cover the sill, this dual-function design reduces interior cleaning frequency by 40% and lowers cab noise levels by 15% at highway speeds, significantly improving driver comfort during long hauls

Built to withstand frequent foot traffic, temperature fluctuations, and exposure to dirt, oil, or cleaning fluids, the assembly uses high-performance, durable materials. The main body is crafted from rigid PVC (polyvinyl chloride) reinforced with 15% glass fiber—this composite resists bending, cracking, and discoloration even after 50,000+ entry/exit cycles. The top surface is coated with a 0.5mm-thick wear-resistant polyurethane layer that maintains its textured finish despite scuffs from work boots or tool impacts, unlike uncoated PVC that fades or scratches easily. The TPE seal is formulated to remain flexible in extreme temperatures (-40°C to 85°C), avoiding hardening (which breaks the seal) or melting (which causes sticking to the door). This material combination ensures the pressure strip operates reliably for 4+ years in harsh cab environments

Engineered to enhance safety during cab entry/exit (especially in wet or muddy conditions), the pressure strip features an anti-slip top surface and ergonomic edges. The top is embossed with a diamond-pattern texture that increases friction between boots and the strip—reducing slip risk by 60% compared to smooth surfaces. The strip’s leading edge (where feet first contact it) is chamfered at a 45° angle, creating a smooth transition from the ground to the cab floor and preventing tripping (critical for drivers wearing heavy work boots). Unlike flat, sharp-edged strips that pose fall hazards, this ergonomic design prioritizes safety while maintaining a sleek, factory-like appearance that complements the cab’s interior

Designed for hassle-free replacement by fleet technicians or DIY owners, the assembly simplifies installation and upkeep. It requires no drilling, adhesive, or special tools—just align the strip with the sill’s reference marks (laser-etched on the strip) and press firmly to secure the pre-attached clips into the sill’s mounting holes. Installation takes 10–15 minutes, even for first-time users. For maintenance, the strip can be easily removed (by prying gently with a plastic trim tool) for deep cleaning (to clear trapped dirt or debris) and reattached without damaging the clips or sill. Each unit undergoes strict quality testing: wear resistance trials (100,000 simulated foot presses), seal integrity testing (water spray at 3 bar), and clip retention strength checks (ensuring clips hold 50N of force without slipping). Backed by an 18-month warranty against manufacturing defects (e.g., clip breakage, TPE seal failure, or surface wear), it provides Dongfeng KL truck owners with reliable door sill protection and long-term cab comfort
