they vary because some are just the crank pulley, others are crank and alternator... and the exspensive ones replace the whole balancer.

i've been running the mac(not sure if they sell it anymore) crank pulley for 7 years... havent had any charging problems, im even running an electric water pump.(the lights do dim at idle).

if you got a big stereo you might want to think about getting the alternator pulley also.


the balancer ones are nice since your not actually adding another pulley to the crank... your just replacing one.(no extra weight)
i dont see them mention anything about those being undrive though... i would ask before you order them.

A few mention it in the description but im looking for on to improve rear wheel horsepower and better gas mileage and there is really only one that says that but its 250

just get the crank piggyback pulley or if you think your going to need the extra juice get the crank and alternator set

I have a 34% reduction one on the Crank, bolted the Balancer on it, no problems with it. I don't have anything electrical in the car that would pull that much to make a difference.
