These pulleys are precision CNC'd from aircraft grade billet aluminum and reduce the rotating mass by a whopping 8.5 lbs! All pulleys with exception of power steering pulley ARE NORMAL DRIVE (NOT UNDER-DRIVE). Our testing has determined that ONLY the power steering pulley should be under-driven (slightly).
