About This Product
This KB Performance piston set is designed for Milwaukee-Eight owners performing a 120 inch big bore conversion with a .030 inch oversize. Part of the forged Super Duty series, these pistons include a hard-anodized crown and top ring groove to reflect heat and prevent ring groove wear. The specialized Line2Line abradable powder coating allows for a zero-tolerance installation, as the coating wears in to create a perfect piston-to-cylinder fit. This kit fits 2017 to 2025 114 inch M8 engines and works with the stock 4.500 inch stroke. No case boring or flywheel rebalancing is required since they maintain OEM weight. This set provides a 10.9:1 compression ratio for improved performance and ring seal.
Manufacturer part number: KB542LCA.030.
