SHOWA Damper Diaphragm — a spare part designed for the refurbishment of suspensions. This flexible diaphragm is an integral part of the reservoir damper circuit and serves to ensure the separation between the hydraulic fluid and the gas cavity, in accordance with manufacturer principles. Designed for installation on SHOWA dampers, it allows for a clean intervention during a service to restore appropriate sealing and consistent hydraulic response on the demanding terrains of motocross.
A wear part to consider during a restoration, the diaphragm is aimed at riders and workshops keen on maintaining the original quality of suspension components. Compatible with many SHOWA dampers mounted on cross models (e.g., Kawasaki KX250, Suzuki RM‑Z450, Honda CRF250R), it integrates into a maintenance operation to limit oil loss and oil/gas mixtures that can alter hydraulic behavior.
For safe installation, follow the manufacturer's recommendations or consult a suspension specialist. This part is supplied new, ready to be installed as part of a refurbishment.
