Dongfeng GX Door limiter assembly with dust cover 6101300-C6101

A key advantage of the 6101300-C6101 assembly is its built-in dust cover, crafted from durable EPDM (ethylene propylene diene monomer) rubber with a shore hardness of 55±5A. The dust cover forms a tight seal around the limiter’s sliding rod and internal mechanism, blocking dust, sand, rainwater, and road debris from entering—common contaminants that cause premature wear of moving parts. Testing shows the dust cover reduces internal component contamination by 98% compared to limiters without protection, extending the mechanism’s service life by 50%. The EPDM material also exhibits excellent weather resistance, remaining flexible at -40°C and stable at 80°C, without cracking or hardening—ensuring long-term sealing performance in extreme climates

Constructed from industrial-grade materials to endure the high cycle count of commercial vehicle doors (150,000+ opening/closing cycles), the 6101300-C6101 limiter assembly balances strength and wear resistance. The main sliding rod is made of chrome-plated 45# steel (plating thickness 10μm) with a surface hardness of HRC 50, reducing friction and preventing rust. The limiter housing is die-cast aluminum alloy (ADC12) with a powder-coated finish, providing lightweight structural support (weight: 0.35kg) and corrosion resistance. The internal friction pads are made of wear-resistant nylon (PA66+30%GF), which maintains stable friction force over time—door opening/closing requires a consistent force of 15-20N, with no significant increase after 50,000 cycles. This robust construction guarantees reliable performance for over 8 years

Exclusively tailored for Dongfeng GX commercial vehicles (including heavy-duty trucks and light cargo models), the 6101300-C6101 limiter assembly strictly adheres to original equipment (OE) specifications. Manufactured using CNC machining and die-casting technology, it achieves dimensional accuracy within ±0.1mm—perfectly matching the Dongfeng GX’s door hinge mounting points and body frame. The assembly’s overall dimensions (length: 180mm × width: 40mm × height: 35mm) align exactly with the vehicle’s door cavity, ensuring no interference with other components (e.g., door wiring, window regulators). It is fully compatible with all Dongfeng GX models produced since 2021, including both driver and passenger doors, making it a direct replacement part for factory assembly or after-sales repairs—no drilling or modification required

The 6101300-C6101 limiter assembly is designed for hassle-free installation and minimal upkeep. It comes with a complete hardware kit, including 4 grade 8.8 high-strength bolts, lock washers, and a pre-assembled dust cover—eliminating the need for separate part sourcing. The dust cover is already attached to the limiter housing, saving technicians time on additional assembly steps. Clear laser-engraved alignment marks on the housing guide precise positioning, allowing two technicians to install the assembly in 15-20 minutes (40% faster than non-OE limiters). For maintenance, the dust cover can be easily cleaned with a damp cloth to remove surface dirt, and the limiter’s self-lubricating internal components require no periodic oiling—reducing long-term maintenance costs. The assembly also includes a 24-month warranty against material defects (e.g., rod bending, dust cover tearing) and manufacturing errors
