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

Optimise suspension behaviour with Yokomo Y2-S144A

For racers and drifters tuning a YD-2, the Yokomo Y2-S144A piston set is a targeted upgrade. Specifically made for the YD-2 SLF Big Bore Shock, these pistons use 1.4mm openings to improve suspension compliance and help the tyres maintain contact on slippery surfaces.

Enhanced traction when surfaces are slippery

The 1.4mm orifices reduce harsh damping spikes and encourage smoother shock travel, which helps the car hook up during cornering and gives a more controllable drift window.

Works with broader oil ranges

Even though light oils are standard for drift, the larger hole diameter allows tuning with heavier oils in the #200 to #300 bracket to refine mid-speed damping and overall balance.

Protects seals and internal oil longer

Alongside handling improvements, the Yokomo Y2-S144A pistons help limit fast water intrusion and protect silicone lubricants, supporting sustained shock performance and simpler maintenance routines.
