Product Introduction

Shock absorbers for HOWO 371 trucks are divided into two main categories:

1. Cab Shock Absorbers: Installed on the cab's front and rear suspension, they reduce cab bounce and vibration caused by road shocks, significantly improving driver comfort. They feature integrated coil springs or rubber buffers for enhanced stability.

2. Axle Shock Absorbers: Mounted on the front and rear axles, they work with leaf springs to dampen chassis vibrations, preventing excessive suspension movement and protecting other drivetrain components.

All shock absorbers undergo strict quality control, including pressure testing and fatigue testing, to ensure they meet the high durability requirements of heavy-duty commercial vehicles.
