Is there such a thing as a under drive pully kit or do you buy them individually ?

Are they hard to install for a complete nitwit ?

Fairly easy install, They sell them as a kit.

Best place to buy ?

Thanks

Tough call, I know I went with STEEDA because i couldn't pass up the deal at the time. To be perfectly honest I don't know if I would do them again given the choice. On the 5.0L they made more of a difference in my opinion. When we installed them on my 2002 and on my friends 2006 GT we noticed no change. Others may have different opinions or input though.

Thanks. That was the next thing I was going to do..I heard 14 hp at the wheels. has anyone in this group done it to the 05-09 ? Was there a noticable ?

Thanks

you can buy them at americanmuscle.com and steeda a better than the no name,you'll need a impact gun to remove them with puller.

Do stick with the Steeda pulleys,most pulleys by other companies are piggy back!You don't want them.:wink:

When I did mine back in the day, I bought a set of MAC under drive pulleys...
When I went to install them I had to machine 3/8 of an inch off the water pump pulley!!! That was not fun and I was not impressed!

On a side note once it was installed, I did notice a HP change....there was greater HP's but not much, enough to notice...!
But if I were you I would stay away from MAC unless you have access to a Lathe!
If you do not have Under drives by now it will be the best 100 bucks you ever spent!

OK, so here they are for 05 to 09 V8 and V6"

Steeda Underdrive Pulley System - 05-09 Ford Mustang

Steeda Underdrive Pulley - 4.0L V6 - '05-'09 Ford Mustang

This is a 2010 improvement for me.

If I could figure out how I can change it, I would change the wordage below with an updated list.
