This is a pack of four Team Associated Factory Team 12mm Big Bore V2 Tapered Screw Mount Shock Pistons, with three 1.4mm holes. These pistons have been machined to provide a precision fit and finish, and feature a tapered profile that allows you to alter the speed of the rebound or stroke. The edges have been radiused for smooth shock action.

NOTE: Screw mount pistons are not compatible with e-clip shock shafts.
