Dongfeng GX truck parts driver's side A Knee guard assembly 5305110-C6200

Built as a critical passive safety component, this knee guard assembly features a multi-layer energy-absorbing structure to mitigate injury risk during collisions. The outer shell is made of impact-resistant PP+ABS alloy (UL94 V-0 grade), while the inner layer integrates a 20mm-thick EPP (expanded polypropylene) foam core with variable density—soft enough to cushion impact yet rigid enough to prevent excessive deformation. It absorbs 70% of impact energy (up to 150J) in frontal or side collisions, limiting knee acceleration to ≤20g (compliant with ISO 61508) and reducing fracture risk. The guard’s lower edge is angled at 15° to redirect impact force away from the knee joint, and it includes a reinforced rib at the hip contact area for added protection during rollovers

Engineered to optimize driver comfort during long-haul operations, the 5305110-C6200 assembly integrates human-centric features. The outer surface uses a soft-touch PVC coating with a matte texture, providing a comfortable contact surface that avoids skin irritation during extended driving. The guard’s profile is contoured to match the natural position of the driver’s knees (100° flexion angle), reducing pressure points by 40% compared to flat-design guards. It includes a recessed storage pocket (180×100mm) with a elastic strap, securely holding small items like gloves or a tire pressure gauge for easy access. The top edge is rounded (R8mm) to prevent scratches, and the color (charcoal gray) matches the GX’s interior for visual consistency

Optimized for long-term reliability in harsh truck cab conditions, the knee guard adopts high-performance materials and craftsmanship. The PP+ABS shell undergoes scratch-resistant treatment (pencil hardness ≥2H), withstanding scuffs from boots, tools, or cargo without visible damage. The EPP foam core is anti-mildew and moisture-resistant, preventing odor buildup in humid environments. The snap-fit clips are made of glass fiber-reinforced nylon (GF30), resisting breakage even after 50,000+ installation/removal cycles. The assembly operates stably in temperatures from -40℃ to 85℃, avoiding brittleness in cold weather or deformation in sun-exposed cabs. It also resists oil and cleaning fluid spills, maintaining performance with minimal maintenance

This A pillar knee guard assembly is designed for efficient installation and long-term cost savings for Dongfeng GX operators. The pre-assembled structure (outer shell + foam core + mounting clips + bolts) allows a single technician to complete replacement in 35 minutes using only a screwdriver and socket wrench—no adhesive or cutting required. The OE-compatible design eliminates gaps between the guard and A-pillar, avoiding the rattling noise or loose fit issues of aftermarket guards (repair costs up to $350). The durable materials extend service life to ≥600,000km—three times that of low-quality alternatives—reducing replacement frequency. By enhancing driver safety and comfort, it lowers accident-related downtime and improves operational efficiency. Backed by a 2-year/300,000km Dongfeng warranty, it provides reliable protection and predictable maintenance expenses
