| High Light | 1-51385091-0 OEM Fit Lower Spring Seat ，High-Strength Cast Iron Trunnion Seat ，ISUZU CYZ51 6WF1 Spring Seat | ||
The Lower Spring Seat with OEM numbers 1-51385091-0 and 1513850910 is a verified direct-fit replacement for ISUZU CYZ51 / CXZ51K / EXZ51K / CYZ51L / CXZ81K heavy-duty trucks equipped with 6WF1 / 10PE1 diesel engines. This lower spring seat is the core load-bearing component of the rear suspension trunnion system, mounted between the trunnion shaft housing and the leaf spring. It is responsible for carrying the vertical load of the leaf spring and transmitting it to the trunnion shaft and chassis frame, ensuring stable suspension performance under heavy loads and challenging road conditions.
The rear suspension lower spring seat is a critical load-bearing component in the rear suspension system of heavy-duty trucks, connecting the leaf spring to the trunnion shaft. It is mounted on the trunnion shaft housing and provides a stable support surface for the leaf spring. When the vehicle travels over uneven road surfaces, the leaf spring transmits vertical loads through the lower spring seat to the trunnion shaft, which then transfers the load to the chassis frame through the bracket. The lower spring seat must withstand high-frequency cyclic loads and impact forces, which is why it is manufactured from high-strength cast iron with excellent compressive strength and wear resistance. Its cylindrical design with flange ensures precise fit and secure mounting to the trunnion shaft housing. The 6WF1 is a 14.256L inline-six diesel engine producing 330–370 PS, used from 1999 to 2007. The 10PE1 is a 15.7L inline-six diesel engine.
