Description

Stock pistons wear down over time, reducing compression and power output—especially under sustained high-RPM operation or forced induction. The WSM Piston Kit delivers OEM-quality construction with engineered upgrades that reduce friction, dissipate heat more effectively, and strengthen critical ring groove areas, giving you reliable performance gains without compromise. Whether you're rebuilding after a failure or upgrading for durability, this is the precision component serious Honda 420 builders choose.
