Yokomo Y2-S144A SLF Big Bore Shock Piston (1.4mm x 4 Hole

YD-2 A variation is added to the piston for big bore shock. By setting the hole diameter to 1.4mm, he can operate it smoothly even when the grip is low. He makes the suspension easier to move, which increases traction when cornering. It is a drift category where oil with a fairly low viscosity is often used, but by widening the piston hole, it is easy to operate even with slightly hard oil (about # 200 to # 300), and silicone oil penetrates into O-rings etc. It will be possible to delay and maintain good condition for a long time.
