These are being sold discounted due to the place that etches the logo and size of the pulley messed up and has some extra marks on it as pictured. It is brand new and never used. Just a cosmetic flaw in the etching. You must have a ZZP modular hub in order to use this pulley. This is good for someone who already has a ZZP modular pulley system on their 3.8L 3800 series 2 or series 3 supercharged engine and want to swap to a 3.5\" pulley. These normally sell for $59.99 each. This is discounted due to the cosmetic imperfection.
For supercharged 1996 to 2008: Buick Park Avenue Ultra, Pontiac Grand Prix, Buick Regal GS, Pontiac Bonnevile SSEI, 2004-05 Chevy Impala SS, Monte Carlo SS, 1996 to 1999 Buick Riviera, etc
