This is a pack of four optional Yokomo Blank Shock Pistons. These shock pistons feature three pre set hole marks on one side, and four hole marks on the other, allowing you to drill out the pistons to the valving you prefer. Plus having the marks on both sides allows you to drill the holes in either 2, 3 or 4 hole configurations.
NOTE: For best results use a sharp drill bit to drill the holes.
