Howo/Sitrak truck parts are engineered for extreme durability, and the VG1642111030_3 AIR SPRING represents the pinnacle of pneumatic suspension technology. Designed for heavy-duty commercial vehicles, this genuine-grade air spring delivers superior ride comfort, load stability, and extended service life. Whether you operate a Howo, Sitrak, or compatible chassis, the VG1642111030_3 ensures consistent damping and reduces wear on axles and tires. This replacement part meets or exceeds OEM standards, making it the preferred choice for fleet managers and owner-operators worldwide. With its robust rubber compound and precision-machined pistons, the VG1642111030_3 guarantees optimal performance even in the harshest off-road conditions.
The AIR SPRING is not just another air spring; it’s a precision-engineered component that transforms your truck’s handling. Manufactured using high-tenacity fabric reinforcement and low-hysteresis rubber, this air spring absorbs road shocks efficiently, reducing driver fatigue and cargo damage. The integrated bead plate and seamless crimping ensure leak-free operation, while the anti-abrasion outer cover extends service intervals. For fleet operators, the AIR SPRING reduces downtime and maintenance costs, delivering a clear ROI within the first 20,000 miles.
Compared to conventional coil springs, the air spring offers adjustable ride height, progressive spring rate, and superior dampening. The AIR SPRING is directly interchangeable with original equipment, requiring no modifications. Its compact design (height 320mm, outer diameter 190mm) fits most suspension layouts, making it a versatile upgrade for both on-highway and off-highway applications.

The VG1642111030_3 air spring is designed to fit a wide range of Howo and Sitrak models, including T7H, C7H, A7, and the new SITRAK C-series. It also replaces OEM numbers: 812W32260-0001 and WG9725330001. The mounting holes align perfectly with the standard axle bracket, and the air inlet port uses a 1/4” NPT thread for universal connectivity.
Installation takes approximately 45 minutes per side with basic hand tools. Always deflate the system and use thread sealant on the fittings. After installation, perform a leak test with soapy water. The AIR SPRING is delivered with a protective cap and lubrication grease for the bead.
1. Enhanced ride quality – The progressive air spring rate ensures a smooth ride regardless of load, reducing chassis stress.
2. Longevity – The VG1642111030_3 uses a high-grade EPDM compound resistant to ozone, oil, and weathering.
3. Fuel efficiency – By maintaining optimal ride height, the air spring reduces aerodynamic drag and rolling resistance.
4. Braking stability – Consistent axle load distribution improves braking performance, especially on uneven surfaces.
5. Noise reduction – The elastomeric damping absorbs high-frequency vibrations, lowering cabin noise levels by up to 6 dB.
Field tests in the Australian outback and Siberian winter confirm that the AIR SPRING maintains its elasticity and sealing integrity from -40°C to +80°C. The double-convoluted design provides a progressive spring curve, ensuring that the vehicle remains level even when loaded asymmetrically. Additionally, the AIR SPRING is compatible with electronic leveling systems (ECS) and height sensors, enabling automatic ride height adjustment.
Each AIR SPRING is individually packaged in a reinforced carton with foam inserts to prevent damage during transit. The package includes the air spring unit, two mounting bolts, and a detailed installation manual (EN/DE/FR). Bulk orders (10+ units) are shipped on pallets with protective wrapping.
For fleet replacement programs, we offer customized labeling and just-in-time delivery. The AIR SPRING is stocked in our regional warehouses in Europe, Asia, and the Americas, ensuring rapid dispatch.
