[b] Craven Speed Crank Pulleys are machined from 6061 T6 aircraft aluminum. This strong material is also very light. Our pulley may be the lightest available for the tC. The stock crank pulley on your tC weighs in at 3.65 lbs, while the aluminum version pushes the scale to only .85 lbs. That is a reduction of over 75%. This won't have an effect on your curb weight, but your engine will notice the lack of rotating mass. You'll see the needle climb faster as the engine easily turns the crank from a stand still.
