We have used them on many different builds with great success, no issues. You can expect around 5-10 rwhp gain.

We keep the SLP UD Pulley and Serpentine Belt in stock. It comes with a new GM Crank Bolt.

SLP Underdrive Pulley $179.95

Might as well do a cam swap while you're at it. It's a lot of work to swap the crank pulley, just for it's sake. Not worth it unless you plan on doing the cam too, or if there's something wrong with your stock one.

Does the SLP have a/c 10% UD like ASP unit?

Anybody run into charging issues running the underdrive pully? I had a different make/model vehicle years ago, and at idle the volt meter on the dash would drop below 12V...you could see the headlights and dash lights dim at night when I was at idle. Only above 1000 rpm would the problem go away. Every since then, I've been very leary of the underdrive pullies.

The A/C side stays the same size as stock.

I had nothing but trouble with the ASP Underdrive, haven't tried the SLP yet though.

MTPZ06

Apparently no issues with keeping a charge well above 12V at idle?
