Fine tune your damping with Yokomo Y2-S144A

Modelers seeking crisper control for the YD-2 will value the Yokomo Y2-S144A piston set. Designed for the YD-2 SLF Big Bore Shock, the pistons incorporate 1.4mm orifices to promote smoother damper travel and better tyre engagement when grip is poor.

Consistent handling on low traction surfaces

These 1.4mm holes ease fluid flow and reduce abrupt damping changes, helping the chassis settle more predictably during cornering and providing steadier traction for slide control.

Allows practical oil tuning options

While light shock oils remain popular for drifting, the increased orifice size makes it viable to explore oils in the #200 to #300 range to tune mid-speed damping and overall balance.

Reduced ingress and extended component life

In addition to performance, the Yokomo Y2-S144A pistons help limit rapid moisture ingress, protecting silicone oil and seals so that shocks hold consistent damping between services.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Do these pistons change shock travel or sag?

Pistons alter damping characteristics rather than static travel, so ride height and sag should remain largely unchanged unless other parts are altered.

What oil tests should I run first?

Try a baseline #200 then compare to #300; monitor rebound, body roll and steering to choose the best trade off for your track conditions.

How do I spot wear on these pistons?

Look for scoring on piston surfaces, degraded O-rings or inconsistent damping; replace worn parts and refresh oil to restore performance.
