mr gasket is pretty reputable. but since those look like UD pulleys, be prepared for charging issues.

i tell everyone to not get under drive pulleys. i has seen countless people on here have issues with them, including my self. they slow the alternator so much people usually have issues at idle. even with high amp alternators. imo they are not worth the hassle even if they were free.

Re: Pulleys

Think foxes have charging problems with Udps due to small amp alternators. I could be wrong. You could always upgrade alternator too but that's not cheap.

i still had problems after alternator upgrade. i went to a 150 amp. the problem is also the alternators are designed to spin a certain speed. i ended up keeping my pulleys except for the alternator pulley i switched out out for an overdrive. this totally defeats the purpose. but i didnt have my stock pulleys, plus the the new ones were prettier.

Stay stock and save yourself some headaches.
The issues they can cause are not worth the few HP you might gain.
You can realize as much or more HP recovery by installing a larger alternator and an electric fan, which may cost a bit more, but you'll get more benefits in return too.

If your not having cooling issues but just charging issues you could overdrive the alternator leaving the ud crank pulley. This will get it spinning back the rpm it should. But besides that you will probably have to check salvage yards.

I am currently BBC having cooling problems. It is fine going down the road but gets warm at idle.

Yeah that's common also. So many people have problems with these damn ud pulleys. I don't know why Noone sells factory replacements.

Check rock auto, MPs auto salvage, and Emmet head auto (site sponsor)
