“HCC3800842.” Product names and specifications can vary across manufacturers and industries. However, the designation “1.00mm Oversize” typically indicates that the piston and ring kit is designed to accommodate an engine block that has been machined or worn beyond standard specifications. The oversize pistons are slightly larger in diameter, and they come with corresponding oversized piston rings to ensure a proper fit within the engine cylinder.
