Who makes a good Underdrive Pulley?

Looking for one with as few problems as possible. I heard with one the crank bolt backs out, another one the belt likes to jump off.. Obviously don't want to spend more than the average cost.

So.. who's good?

Powerbond/SLP is "touted" for having non-belt-slip ribs and higher walls. ATI is touted for being a harmonic balancer, not just a pulley. And most people run the ASP, lol.

Got the Powerbond here, no problems yet. The pulley does have a higher wall where the belt goes around it, I don't see anyway that it could slip off.

Couldn't go wrong with the ASP or powerbond.

Just stay away from March unless you like using makeshift tools and supersize pullers to take it off.

SLP, March & Powerbond are all the same pully. I have the SLP and got it because of belt slippage issues a friend of min had with his ASP untill he got the KaTech tentioner. I gained 12rwhp & 12rwtq with it. No charging issues so far either.

Iv got a March on my car and Iv been quite pleased. w/ the pulley and a catback, the car dynoed 339rwhp and 350 rwtq. My buddy put it on (he has a lift) and it took maybe 20-30 minutes tops.

I have no reason in taking it off right now. I bought it to replace my stock pulley, its doing its job. Perhaps my opinion on it will change if i ever need to take it off.

I have had good results with the March pulley on two different LS1 cars. However, I haven't had to remove one.

Arctic....didnt you go through a big ordeal with this? That's something to think about when deciding which one to go with....
