I just picked up a set of BBK UD pulleys for my 03 GT. What effect will they have on the altenator? Is there anything I need to lookout for during or after I install them?

just keep an eye on your temp gauge and alt gauge and everything should be fine. They shouldnt harm your ride any at all.

An alternator on it's way out might struggle with UDP's, especially with the Mach 460 system and any custom audio/video added...

But it should be no problem at all.

had no probs with mine - and its hot here. I even have my timing jacked up and done have any temp problems, let alone charging problems. the only people that may have charging problems are maybe those with an aftermarket stereo and sit at idle for LONG times, like 15+ minutes at a stop at a time etc.

Thanks guys...it looks like I'll be installing them this weekend..anything I should look out for when doing the install?? looks pretty simple to me.

you wont get the alternator bolt off with out a impact wrench and u need a harmonic balancer to get the crank pulley off
