Dongfeng VR truck parts Right upper foot pedal 8405210-C1100

Built to withstand repeated foot pressure (up to 200kg per step) and harsh working conditions, the pedal uses 5mm-thick Q345B low-alloy steel for the main body—boasting a yield strength of 345 MPa and tensile strength of 510 MPa. The pedal’s understructure features 4mm-thick reinforcing ribs (spaced 60mm apart) that distribute load evenly across the cab sill, preventing bending or deformation even under uneven foot pressure. Finite Element Analysis (FEA) testing confirms it endures 150,000+ step cycles (equivalent to 10 years of daily use) without permanent damage, and maintains structural integrity in temperatures from -40°C (cold winters) to 80°C (hot engine bays). Unlike thin aluminum or plastic pedals that crack or warp, this heavy-duty steel design ensures reliable performance for long-haul truck operators

Designed to prevent slips during entry/exit (critical for wet, icy, or muddy conditions), the pedal’s top surface features a dual anti-slip system. First, a raised diamond-pattern texture (2mm depth) creates friction between the shoe and pedal, even with wet footwear. Second, the surface is coated with a wear-resistant polyurethane (PU) layer (1.5mm thickness) that enhances grip and resists abrasion from work boots. The pedal’s edges are rounded (R5mm radius) to avoid catching on clothing or damaging shoes, while two 8mm-diameter drainage holes (located at the front corners) channel rainwater or mud away from the surface—preventing water pooling. Unlike smooth or lightly textured pedals that become slippery in bad weather, this design reduces slip risks by 70%, ensuring safe entry/exit for drivers and passengers in all conditions

Engineered to align with human movement mechanics, the pedal features an ergonomic layout that reduces strain during cab entry/exit. The pedal’s top surface is angled at 12° (relative to the horizontal) to match the natural stepping motion, minimizing ankle fatigue for drivers of varying heights (1.6m–1.9m). The pedal’s width (120mm) provides ample foot placement space, accommodating work boots of all sizes, while the 35mm height (from the mounting surface) ensures a smooth transition from the lower step to the upper pedal. A 10mm-wide rubber bumper (installed on the pedal’s rear edge) cushions contact with the cab sill, reducing noise during stepping and preventing metal-to-metal wear. Unlike poorly shaped pedals that force awkward body positions, this ergonomic design enhances comfort for frequent entry/exit—common in delivery or construction truck operations

Designed for hassle-free replacement by fleet technicians or DIY owners, the pedal simplifies installation and upkeep. It includes a complete hardware kit: 4 M8×25mm high-tensile bolts, lock washers, and a foam gasket (pre-cut to fit the mounting surface) that reduces vibration transfer to the cab. Two laser-etched alignment marks on the pedal’s understructure line up with reference points on the VR’s right cab sill, eliminating guesswork and reducing installation time to 15–20 minutes. Maintenance is minimal: the anti-slip PU coating resists staining and can be cleaned with soap and water, while the steel body’s zinc-plated finish (80μm thickness) prevents rust—passing 800 hours of neutral salt spray testing. Each unit undergoes load testing, slip resistance verification, and dimensional checks, backed by a 24-month warranty against defects (e.g., bending, coating peeling, bolt failure)
