Just wondering if anybody has the belt numbers for a 25% underdrive pulley. I wont have a problem with charging, powersteering, and cooling if I go 25% will I?

its for an ls6. Dont know if the ls2 has the exact same belts or not so I thought I'd just throw that in.

Here is the NAPA part number off the main belt:

25-060790 It's a 6 rib 79 inch belt.

The AC belt wore off the part number sorry.

No problems with a -25% pulley.

I have a 25% UD Harmonic Balancer on my car.

I posted in this thread the exact belts I used:
