Yokomo "X" Shock Tapered Piston (Black) (2) (2 Hole/1.5mm)
This is a pack of two optional Yokomo X Shock Tapered Pistons, and are intended for use with the big bore "X" Shocks. With the use of a tapered piston it is possible to change the damping characteristics of the shock stroke. When the taper is facing up the shock will compress more easily but have less pack. When the taper if facing down the shock will rebound more easily while retaining pack.
