This SHOWA O-ring integrates during a shock absorber service to replace the old seal and prepare for the installation of a new SPI or dust seal. It is a simple yet essential wear part to limit infiltration and premature wear of the rod and internal components. Particularly suitable for motocross bikes such as SUZUKI RM-Z 450 (2025), HONDA CRF 450 R (2024), and KAWASAKI KX 250 (2024) — always check compatibility with your model before installation.
Workshop tip: clean the seating surfaces, check the condition of the rod, and use the appropriate tools for a clean installation. Replace sealing elements together for a lasting result.
