Why We Build B18C Forged Crankshafts
Honda stopped making B18C cranks with no replacement plan. Every month, more Type Rs get scrapped because owners can't source engine parts.
We kept the exact stroke and specifications Honda designed. Make it a performance modification as well as a direct replacement that maintains the original engine character.
