The DJI Matrice 400 Gimbal Dampers utilize upgraded silicone-filled construction to isolate vibrations for single- or dual-gimbal mounts, supporting payloads up to 1.4 kg per damper with low-frequency damping for sharper imagery. Rated for 400-1000 hours of service life, they install easily on the gimbal cradle and are essential for maintaining precision in high-speed or turbulent flights.
