Installs in place of your factory crank and water pump pulleys. This is a BOLT on installation. REALLY frees up horsepower! Expect a nice performance gain, 5-7 wheel horsepower is typical. This device works by slowing down or "underdriving" your vehicles accessories. That includes all pulley driven items (alternator, water pump, power steering, A/C, etc.). The less horsepower your engine spends driving those, the more power it has to move your vehicle forward. Zetec motors are INTERNALLY ZERO balanced, meaning the factory pulley IS NOT a harmonic dampener of any kind. This means swapping the crank pulley will have NO adverse effects on engine longevity, Massive's staff has logged literally over 250,000 collective miles with these pulleys installed and have seen NO unsatisfactory qualities. Made of super light weight 6061 aluminum, this pulley also allows the engine to rev more freely by replacing the heavy cast iron pulley it replaces. Weight differences between this and competitors pulleys is less than 2 ounces yet pulleys offer 90% higher total rigidity and far better overall strength. These are not cheesy knock offs with fitment problems often found on ebay, these are the real deal. Massive makes our pullies with the highest precision machinery in the business today, and utilizing ultra close tolerances and a super strength design that will last forever. Fairly straight forward installation, comes with its own instructions. These high quality Massive pieces are quality made in house at Massive in the USA. If you need assistance, let us know and we'll walk you through it! Should take less than 1 hour for a novice car guy (or girl). Pulleys come anodized MASSIVE PURPLE. Has the Massive logo and a crank position mark machined into the faces. For A/C cars only.
