Hello, I have an 01 GT and I have a friend that has a extra set of March underdrive pulleys from a 96 Cobra. He took them off because he got a supercharger and he said if they will fit he will give them to me. Does anybody have any knowledge about them fitting on a 01 GT. Also i was just curious, from owner who own underdrive pulleys on their 4.6 GT how much of a diffrence do they really make? Thanx

 

March makes piggyback udp's which are practically useless... even if they did fit on your car dont waste your time.

 

+1, don't waste your time. get steeda UDP's!

 

and 2nd they wont fit your car buddy... sell them and buy steeda udp's
