This is a set of four PSM 6×1.3mm R2T1 Pro Shock Pistons, designed as an optional part for the Mugen Seiki MBX8 1/8 Kits. These pistons feature a tapered valve hole profile that can be used to adjust compression (taper up) or rebound characteristics (taper down). Plus, PSM machines these pistons with an edge-radius on both sides, helping to reduce friction on the shock body, for ultra smooth compression and rebound characteristics.Â
