WISECO Piston Kit with a 4.250-inch bore for 124 CI CVO 117-inch M8 applications. This high-compression piston kit features an 11:1 compression ratio for added power, an ArmorX™ piston coating for protection in extreme conditions and reduced wear, and an ArmorFit™ skirt coating that auto-adjusts to the cylinder wall to support smooth, quiet operation without measuring clearance.
The dome design improves flame travel to maximize air/fuel burn efficiency. A Superfinish piston pin reduces friction and improves scuff resistance, while enhanced pin oiling supports lubrication and reduced friction. Augmented ring land details improve ring seal and function, and dedicated rings provide precise fit with improved compression and oil control. The kit includes two pistons, rings, piston pins and circlips. It is made in the USA and fits OEM and Screamin’ Eagle cylinder heads.
