wat's the difference????
 

Can anyone tell me what's the difference between...crankshaft pulley, underdrive pulley, and power pulley....which do you suggest if they are actually different at all?

Underdrive pulley = any pulley that's larger than stock size, which underdrives the component its attached to.

Power pulley = ??? I don't know... AEM calls them power pulleys maybe... or could be referring to the alternator pulley?

Crankshaft pulley = pulley on the crank ;)

The AEM set comes with the AC and alternator pulleys, which in turn underdrive the PS.

the UR set comes with a crank pulley and (I'm not sure what else, if anything)

i read - but have now forgotten - that one of those is a bad idea to replace. i think its the crankshaft pulley. something about it causing problems. :confused:

crankshaft one is supposed to be the one that throws off the centrifical force and messes up the motor....

Some people I know have them and have been fine but I've heard some bad stories over te yrs also...

I mean pulley sare pulleys just that some companies have diff names for there's..:yes: :yes: :yes:

thank you for confirming. :yes:
