After months of research and dyno testing, our engineers have come up with what we believe to be the highest-quality 4.6 underdrive-pulley set on the market. Constructed from lightweight billet steel, this SFI-approved package offers increased power, quicker revving, and unmatched durability. It's available in two versions, to fit 1996-2001 1/2 and 2001 1/2-2004 SOHC models.

Notes: On 2001 models, it is necessary to determine which type of water-pump pulley the engine uses. Vehicles equipped with a convex (older-style) pump face must use Pulley Set 847-M10000. Vehicles equipped with a concave (newer-style) pump face should use Pulley Set 847-M10001. Both sets come with an installation bolt (not shown).
