This is a "Billet Aluminum GN1 Belt Tensioner and pulley" for a 1986 or 1987 Buick Grand National, T Type, Turbo T, or GNX 3.8 liter turbo V6. Great replacement for a broken original cast aluminum Tensioner bracket. Not only does this piece look amazing, it is built out of high quality billet aluminum to ensure durability. This is a direct replacement for the factory bracket, and uses the original hardware. Pulley not included, you will utilize your original pulley or purchase a billlet one.
