I am looking to get some Underdrive Pulleys for my V6. I've looked everywhere on the net and cant find any for my engine. I have found many for 4.6 and 5.0L's. Could someone tell me of a site that I could purchase them. Looking for 42%. Must be new, no used.

 

i don't know about %42 but AM has UDP's for sixers. i think they are a BBK brand

 

rpmoutlet.com has 42% udp but i would not buy anything from them. It took me 3 phone calls to get all the pieces for my headers from them.

 

get an asp from autobadges, the only one for 42% is RPM which you DONT want to buy from

 

i wouldnt go with the 42%. i have heard many, many complaints about charging issues (dim headlights, battery drainage with stereo system combos, etc.). most people recommend the 25%. stangmods.com would be your first choice. i got the three piece kit from vmptuning.com, as it comes with an OVERDRIVE pulley for your alternator. voila, no more charging issues.

 

go to latemodelrestorations.com they have some under drive pulley kits for a 3.8
