This is a package of two 16mm Conical Shock Pistons with 10 possible straight Pre-Marked holes from Ultimate Racing. These pistons are partially drilled so that each driver can finish making the number of holes they desire according to their needs. These pistons are manufactured using a CNC process to ensure concentricity between the piston and the shock body while maintaining quality across different productions. Thanks to their conical shape, depending on how we mount the piston, we can adjust the resistance the shock absorber offers to compression or extension. Mounting the piston with the cone facing up will facilitate compression, while mounting the piston with the cone facing down will facilitate extension.
