Upgrade your damping control with the Yokomo S4-S17213 shock piston. Made for 13mm shock bodies, this piston uses two 1.7mm ports and a 2.0mm plate to help you micro-tune compression and rebound behaviour.
This piston installs cleanly in Yokomo SOR-020 and SOR-020D shock assemblies, giving consistent results whether you are testing on carpet or hardpack. Use it to refine handling and corner balance.
