This aluminum pulley set is designed as a stock diameter, direct replacement for your factory OE pulley set. This set has a overall weight reduction of 62% over the factory spec. The stock pulleys weigh 6.25 lbs, compared to Tomioka Racing weight of 2.4 lbs, allowing more power and faster revs by minimizing the rotational mass of the pulleys.
