Built for YD-2 series SLF big bore shocks, the Yokomo Y2-S126TA SLF tapered piston was developed with TeamYOKOMO DRIFT insights to offer a simple but effective way to change shock behaviour by flipping the piston.
The tapered profile lets you tune handling rapidly: tapered side down yields a softer rebound, while the reverse orientation eases compression. This lets drivers adapt their car to different drift styles and track conditions.
The diagonal hole design takes advantage of fluid dynamics to keep normal movements smooth and to maintain damping force when gaps form, helping stability during aggressive driving lines.
The six 1.2mm ports are intended to give a softer shock response without starving the oil film between the O-ring and shaft. Using shock oil around #300 is a sensible baseline to avoid film breakdown.
