Dongfeng GX upper sleeper Pneumatic strut assembly 7600080-C6100

Built to endure the frequent opening/closing cycles (up to 10,000+ times annually) and harsh cabin environments of commercial vehicles, the 7600080-C6100 pneumatic strut uses industrial-grade materials. The outer cylinder is made of seamless aluminum alloy (6061-T6) with a wall thickness of 3mm, offering excellent corrosion resistance and impact strength (able to withstand 500N lateral impact without deformation). The internal piston rod is chrome-plated (plating thickness: 8-10μm) to reduce friction and prevent wear, while the seal ring is made of high-temperature resistant nitrile rubber (NBR) that maintains airtightness at temperatures ranging from -40°C to 120°C. Additionally, the strut’s air inlet is equipped with a 5μm filter to block dust and debris from entering the internal chamber, avoiding valve jamming and extending service life to over 5 years

Exclusively designed for Dongfeng GX commercial vehicles (including heavy-duty long-haul trucks), this pneumatic strut assembly strictly adheres to the original equipment (OE) specifications of part number 7600080-C6100. It is manufactured using CNC precision machining, achieving dimensional accuracy within ±0.1mm—seamlessly matching the upper sleeper’s mounting brackets and the vehicle’s cabin frame. The strut has a total length of 480mm (extended) and 290mm (compressed), with two M10×1.5 threaded end fittings that align perfectly with the Dongfeng GX’s pre-drilled mounting holes. It is fully compatible with all Dongfeng GX models equipped with upper sleepers (produced since 2021), making it a direct replacement part for factory assembly or after-sales repairs—no modification to the cabin structure or sleeper frame is required

The 7600080-C6100 pneumatic strut integrates multiple safety features to ensure reliable operation. It includes an overpressure relief valve that releases excess pressure (above 1.0 MPa) to prevent cylinder burst, while a one-way check valve locks the strut in place immediately if air pressure is lost—preventing the upper sleeper from suddenly falling. The strut’s end fittings are reinforced with steel washers to distribute load evenly across the mounting points, avoiding bracket damage from concentrated stress. Additionally, the piston rod is equipped with a scratch-resistant coating that prevents rust and corrosion, ensuring smooth movement even in humid cabin conditions (e.g., after cleaning or in rainy areas). These safety mechanisms meet international automotive safety standards (ISO 11940), minimizing accident risks during use

Designed with user-friendliness in mind, the 7600080-C6100 pneumatic strut assembly simplifies installation and maintenance. It comes with a complete hardware kit, including 4 stainless steel bolts, lock nuts, and mounting washers—eliminating the need for separate part sourcing. The strut’s lightweight design (only 1.8kg) reduces handling effort, and the clearly marked air inlet (equipped with a quick-connect fitting) allows for easy connection to the vehicle’s pneumatic system (installation can be completed in 15-20 minutes by a single technician). For maintenance, the strut requires no regular lubrication (thanks to its self-lubricating piston) and only needs annual visual inspections to check for air leaks or seal damage. It also includes a 24-month warranty against material defects (e.g., cylinder corrosion, valve failure) and manufacturing errors, providing confidence for Dongfeng GX owners and repair facilities
