Underdrive pulleys FS

I have a set of March UD pulleys for a 79-93 5.0 I had them on for about 3 months then took them off they are the steel ones. They come in the original box with the directions and everything

35 bucks plus shipping

Why you getting rid of them?

Why are you selling them? Did they not perform well? What's the negatives???

Cause in 86 the crank pulley wont fit my car so the crank spinning at normal speed and the alt and waterpump on under drive made no difference cause I couldnt put the crank pulley on lol

Its a completly different bolt pattern for the crank on 86 they onyl fit 87-93


thats why the crank pulley in the pic looks brand new. Cause it is haha has never been installed

I see, makes perfect sense to me...dead weight...I just asked because I am installing some on mine and don't really expect alot out of them.

I been considering the same thing, I've heard + & - about these. Good bang for the buck, then minimal gains. So after hearing everyone comment on this site and others, I've come to the conclusion that I still don't know! I guess a gain is a gain and if you want them, get them!

I say if you get them at a great price, why not....I bought some on Ebay but just have not installed them yet. I plan to install eventually and see if I can tell a difference...like I said, not expecting much, but they were cheap so we'll see.

I didnt notie anything but like I said I didnt have the crank pulley instaled so thats the main reason
