Go Fast Bits Underdrive Pulley Kit Subaru WRX 2008-2014 / STI 2008-2021 Eclipse_1989-1994 00 Grade 8 boltThis GFB Pulley Kit comes with the crank, alternator and power steering pulleys as well as the belt needed for install. Having large heavy pulleys spinning takes away power that is better spent moving the car. This kit takes care of that by replacing the crank pulley with a lighter version that underdrives the power steering and alternator yet leaves the A C compressor spinning at normal speeds.
