Features: 1. Utilizes cushioning principle to enhance shock absorption performance, improving ride comfort, especially when driving over uneven surfaces such as potholes and bumps. 2. Improves vehicle stability when driving on non-asphalt, rough roads, or during sharp turns. 3. Helps reduce body vibration caused by uneven road surfaces, minimizing driving noise. 4. Slightly increases vehicle height to improve ground clearance and obstacle passability. 5. Helps protect the shock absorber and suspension system, extends the lifespan of the shock absorber, and prevents damage to the shock absorber spring oil seal from excessive movement.
