so i bought the udp's from americanmuscle becuase they rock. i was wondering do alot of you guy just leave the stock alternator pulley on and just put the crank and water pumper pulley on only? iam thinking i might do that.

I put all three of mine on. and i have a hard hitting stereo, never had a problem. unless you count when the heater is blasting, the lights are on and the stereo is maxed out, then i do get a small flicker in the headlights.

I have BBK pulley and did not keep alternator pulley on as it decreases your charging and had this meter tested. Pulleys are nice wheels even spin with track control on.

I've got steeda's, they're better.. But that's beside the point.. I had switched out the alt pulley originally, then my alt took a crap on me and I had to replace it, now i've got the stock size on there and still get some dimming with my system..

They shouldn't spin w/ traction control on.
