A beautifully CNC machined underdrive power steering pump pulley by VAC.
Machined to exact tolerances and hard anodized for durability.
When every last bit of reliable output counts on the track, get our pulley to insure the lowest parasitic loss.

The VAC S14 Underdrive Power Pulleys are now lighter than ever. Using only virgin aluminum, a hard anodized finish, and the tightest tolerances, our pulleys are used on the fastest S14s on the planet.
There lightweight design optimize performance and response while under-driving components for proper function (reducing pump cavitation) at race RPMs.

A must for track cars, they can also be used on a max performance oriented street car. (For a street vehicle with a lot of in car entertainment, we do not encourage under-driving the alternator.) Chose and individual pulley above from the drop down menu
Our pulleys are precision made from 6061 T6 Billet Aluminum and are hard anodized for durability (satin black only).
