What would be the best under drive pulley or are they all the same?

I'm not sure what the best is but I have a Powerbond 25% UD pulley and it performs just fine.

one of them keeps the ac pulley the same size, but reduces down the operations pulley. that one is the most recommended.

Keep in mind that those of us running a 25% are usually cammed with a higher idle. Toss a 25% on a stocker and you might see some interesting behavior...

So it wouldn't be a good idea to put a 25% on a stocker?

Check out the Fluidampr LS3/L99 under drive pulley. 25% under drive on Alt / PS / WP, stock on A/C Compressor. There are a lot of topics on this. Do a search. Be aware not all pulleys are made equal.

The Fluidampr product is unique in how it balances the engine.

I would also recommend the APR bolt to replace the stock one.
