Product Description

The W01-M58-7894 air suspension spring is a core vehicle suspension component that uses compressed air as the elastic medium.

Functional Benefits

Air springs dynamically adjust vehicle height and suspension stiffness through compressed air inflation/deflation. When fully loaded, the system automatically inflates to prevent body sinking; when unloaded, it deflates to maintain soft suspension. This load-adjustable capability maintains stable body posture under various conditions, improving comfort and stability on uneven roads while reducing body roll and pitch during high-speed driving and cornering.
