The shock buffer bushing is a key component of the suspension system, designed to absorb and cushion the impact between the shock absorber and the vehicle body or chassis. Made of durable rubber or polyurethane, it helps reduce noise, vibration, and harshness (NVH) during driving. Positioned at the top or bottom of the shock absorber, the bushing improves ride comfort, protects suspension components, and extends the service life of the vehicle under various road conditions.
