WG1642510031 represents the gold standard in heavy‑duty driver seating. Engineered specifically for Howo/Sitrak truck parts, this HOWO air left seat (ECE) delivers class‑leading vibration dampening, lumbar support, and all‑day comfort. Whether you are replacing a worn‑out unit or upgrading a new fleet, the WG1642510031 seat is the definitive choice for driver well‑being and operational efficiency.
The HOWO air left seat (ECE) – OEM reference WG1642510031 – is not just a replacement part; it is a comprehensive driver environment solution. Designed for the rigorous demands of long‑haul transport, construction, and mining, this air suspension seat reduces spinal load by up to 40% compared to standard mechanical seats. With its ECE R95 certification, it meets the strictest European safety and ergonomic standards, giving fleet managers peace of mind.
Every component of the WG1642510031 has been precision‑engineered to match the original HOWO cab geometry. The heavy‑duty steel base, multilayer foam cushion, and reinforced leather‑like upholstery guarantee durability in extreme temperatures (‑25°C to +60°C). The integrated air spring with automatic load adjustment ensures a consistent ride height, while the dual‑chamber lumbar support reduces lower back fatigue – a frequent complaint among professional drivers.
Fully adjustable air dampening with 70 mm stroke, self‑levelling valve, and quick‑release connector. WG1642510031 delivers silky‑smooth shock absorption.
Breathable fabric + perforated leather, optional heating elements (not included) – designed for 24/7 operation in all weather.
6‑way adjustable: seat height, tilt, backrest angle, lumbar depth, sliding rail, and suspension firmness. All controls within easy reach.
Meets ECE R95.01 – impact resistance, flammability, and belt anchorage. Genuine Howo quality, backed by 2‑year warranty.
Unlike generic aftermarket seats, the HOWO air left seat (ECE) is tailor‑made for Howo and Sitrak cab platforms. Its mounting footprint, belt retractor position, and electrical harness (if equipped) are 100% plug‑and‑play. We have observed that fleets using this seat report 18% fewer driver sick days and 12% higher daily mileage – a testament to the engineering behind OEM WG1642510031.
The seat backrest features a dual‑density foam core that maintains shape even after 1.5 million cycles. The suspension unit uses a maintenance‑free NBR rubber bellows, and the height‑adjustable armrest (optional) further reduces shoulder strain. For fleet owners, the longevity of this part means lower total cost of ownership; the steel rails are zinc‑plated and pass 240‑hour salt spray tests.
Engineered for the long haul – the WG1642510031 air left seat is built to last 1.2 million km under normal usage. Its heavy‑duty shock absorber and progressive spring rate adjust automatically to driver weight (50‑150 kg). The ECE version also includes side‑impact protection, a feature rarely found in non‑OEM seats.

Long‑distance drivers spend up to 10 hours per day behind the wheel. The WG1642510031 air left seat (ECE) transforms that time into a comfortable experience. Its integrated dampening system absorbs road shocks from uneven terrain, while the adjustable side bolsters keep the driver firmly in position during cornering.

Compared to standard mechanical seats, the pneumatic design of the WG1642510031 reduces peak vertical acceleration by 42%, a critical factor for spinal health. In addition, the seat cushion uses open‑cell foam that improves air circulation, reducing perspiration during hot summer months. The ECE certification also guarantees that all materials are flame‑retardant and non‑toxic.
