KB542LCA.040 M8 114/117 to 120" big bore conv. piston set. +.040"

For Milwaukee-Eight 114 and 117 engines requiring a .040 inch oversize, this KB Performance big bore piston set offers exceptional durability. These forged Super Duty pistons are engineered with hard-anodized crowns to handle high heat and prevent micro-welding in the ring grooves. The Line2Line self-lubricating coating ensures the tightest possible fit by allowing the piston to create its own perfect tolerance during the initial run-in. This set fits 2017 to 2025 114 inch M8 engines and requires boring the cylinders to the appropriate big bore size. They are designed to work with the stock 4.500 inch stroke and maintain OEM weight, meaning no flywheel rebalancing is necessary. This kit delivers a 10.9:1 compression ratio and is sold as a complete set.
