Default Ordering a smaller pulley

Seems to be it should be straight forward. I currently have a 4.75 8rib on my d1sc ProCharger. Looking to go to a 4.0 8rib. I have seen different people/vendors sell them. Just wanted to make sure that they should all be standard ProCharger pulleys and not knock offs of some sort if that is even possible?

Yea, don't buy cheap knock off pulleys. Buy them from ProCharger or a good vendor.

Thank you. I wasn't sure. Looked like there was some off brand ones out there. I don't want problems.

I was going to go with a 4.25 but the shop just finished one up with a 4.0 and that looks like the route to go for me too.

Oh wow. I thought the D1 was comparable to the novi1500. Novi1500 with 3.75 makes 14-15 peak.
