S54 Underdrive Crank Pulley

A beautifully CNC machined underdrive crank pulley by VAC. Machined to exact tolerances and hard anodized for durability. These pulleys offer the ability to get the additional weight off the front of the crank, as well as underdrive all accessories.
When every last bit of reliable output counts on the track, our pulley can be used to insure the lowest parasitic loss.

This pulley is designed featuring a step on the back side to easily accept our crank trigger rings for your standalone ECU install, whatever manufacturers ECU you are using.
We can also supply you with a gear if you wish to use this pulley to drive a dry sump.

Notes:

  • We recommend this pulley not be used on a street car, race use only.
  • We do not recommend a under-driven water pump pulley be used along with our crank pulley, however you may still underdrive the alternator and power steering.

Image is example only, your S54 pulley will differ from shown
