Our Final Gear Kit is produced for those who are seeking a solution for better results. The ratio of the  gear set is determined through our long research and many actual track tests, so that it is possible to use the performance of your highly modified engine to its full extent.Carefully selected quality materials are used, and every gear is forged for extra strength. Further more, metal surface processing called "hard shot peening" are given to the gears so that they can hold a heavier load more reliably.
