WISECO Piston Kit with Gaskets PK1390

Forged from high-silicon aluminum alloy for maximum strength and dependability. Contain all necessary components for overboring or rebuilding your top end. Feature forged pistons, rings, wrist pins, circlips, and top end gasket. Cylinder sleeves must be purchased separately. Have additional features over standard Pro-Lite parts. Each piston is E-coated on the crown, ring grooves, and pin bore for maximum wear resistance and protection from micro-welding, galling, and detonation. Generally have less machining on the outside, which helps seal up the bore for increased compression. Additionally, boost ports are removed for a more predictable powerband and increased pull on the top end
