JQRacing Black Edition 7x1.4 Flat 16mm Shock Piston (4)
JQ Products Black Edition 7-Hole 1.4mm Flat 16mm Shock Pistons.
Different size holes produce an effect known as ¡§pack¡¨, which affects how quickly the shocks respond. Smaller holes increase the pack of the shock, which will slow down the compression and rebound. This is better suited to smooth tracks with big-jumps and not recommended for rough tracks. Larger holes decrease the pack of the shock, which will make the compression and rebound faster and better suited to rough track conditions. This package includes four shock pistons.
