Description:

For sale, UPD M156 15% Underdrive Crank Pulley. It seems UPD stopped selling these so I'm including a link to the VRP version since it appears to be the same exact pulley.

Pulley was used for roughly 3,000 miles and is in excellent working condition. It has a few minor surface blemishes from using a pulley puller and a small mark from aligning it with the keyway - purely cosmetic and with zero impact on performance or fitment.

I upgraded to a supercharger so I no longer need to run this pulley.

Asking $300 + Shipping.
