Yokomo Y2-S144A 1.4mm Piston Set for YD-2 SLF Big Bore Shock  [Y2-S144A]

Suspension tuning with Yokomo Y2-S144A pistons

RC drivers looking to sharpen their YD-2 handling can fit the Yokomo Y2-S144A piston set. Made for the YD-2 SLF Big Bore Shock, these pistons use 1.4mm orifices to free up suspension travel and increase traction when surface grip is limited.

Improved corner traction on low grip surfaces

The 1.4mm hole size smooths shock flow, helping maintain control when grip drops. That added compliance improves traction through corners and suits drift builds that demand consistent steering feel.

Tuning with a range of shock oils

Although drifters often prefer thin oils, the larger piston orifices let you move up to slightly heavier oils, typically between #200 and #300, to dial in rebound and body control for your setup.

Maintenance and component protection

Beyond handling gains, the Yokomo Y2-S144A design helps slow water ingress, protecting silicone oil in seals and O-rings and preserving consistent shock performance between services.
