gen 4 underdrive pulleys

[ronandkate]

Has anyone heard of a set of gen 4 under drive pulleys? I was thinking about getting one of the sets of 4-5 pulleys that under drive most accessories.

I know there are these for the Gen3 but I have not seen a set for the Gen4 in person as of yet.

Please forgive my ignorance, but what does the underdrive pulley do?

They slow down the accessory drives and save some power. Also makes it easier on the pumps because they are not going so hard at higher RPM's.
