2004-2007 Cadillac CTS-V Belts and Belt Tensioners

Use a solid billet adjustable belt tensioner to eliminate belt resonance commonly experienced from the GM Gen III/IV engines, especially when using ATI dampers.  This tensioner is a direct replacement for the factory piece, but adds the flexibility of adjustment to compensate for variances in the accessory drive system.  Available in anodized black, red, and blue.
