Hey guys, I'm getting rid of my March aluminum under drive pulleys (Performance ratio kit Part # 2010) Just the crankshaft and alternator pulley. 1986-96 F-series pkup w/ 5.0L-,5.8L
And a rebuilt Ford 95 amp alternator from a Mustang.
I'm installing my supercharger and I can't use the under drive pulleys w/ the setup. The alt was upgraded to a 160 amp....because of all the silly lights I have.
If anybody is interested please respond. I wanted to give you guys 1st crack at them before I put them up on Ebay.

 

what are you looking to get out of the pulleys? i might want them...

 

$50 plus shipping.

 

What do they do?

i may be interested in that alternator... im in need of one b/c i have extra lights too
how much you asking for just the alt and do you know how much it would be to ship it to michigan

 

They are underdrive pulleys. They free up some needed horse power.
$50 for the alt + shipping. I'm not sure about shipping price. I'll have to weigh it and go from there.

 

Here are some pics of the goods..........

Often wondered if those things actually accomplish anything. did you see any improvement when you had them on - any problems operating accessoroes??

 

Stumper,

The underdrive pulleys are a no brainer. They simply free up parasitic losses that happen with stock pulleys by driving them faster than they need to be driven. I have the Ford Racing pulleys on my truck, and got slightly better mileage and better performance. Seat of the pants not a huge deal, on these trucks should be worth 8-10 hp at the wheels. Dollar for dollar a great bang for the buck.

On my truck with accessories and lights on, the lights would dim and the A/C fans slow some at idle, but raise up to normal full levels if I so much as breathed on the gas pedal. Caused me some concern at first, but found it to be nothing more.

 

Stumper,
I liked them when they were on my truck. I would still use them but when I install my supercharger it calls for stock pulleys.
If you want these ....$30 + S/H and they're yours. I don't have time to put them up on Ebay.
