Product Introduction

The WG9725520277 leaf spring seat (left side) is a key suspension mounting component used in SINOTRUK HOWO heavy-duty trucks. It is installed between the vehicle chassis frame and the leaf spring assembly, providing a secure mounting point and ensuring proper load transfer from the axle to the frame.

This component plays a critical role in the truck suspension system by stabilizing the leaf spring pack and maintaining correct axle alignment during operation. It helps distribute vertical load, absorb road impact, and improve overall driving stability under heavy-duty working conditions.

Manufactured using high-strength ductile iron or forged steel materials, the spring seat is designed to withstand extreme loads, continuous vibration, and harsh road environments such as mining sites, construction zones, and long-distance freight transport.

The WG9725520277 is widely used on HOWO series trucks and is compatible with multiple heavy-duty configurations. Each unit is processed with precision casting and machining, ensuring dimensional accuracy, strength consistency, and long service life.

All parts are tested for load resistance, crack detection, and fatigue durability to meet OEM quality standards.
