I just got a set and wanted to know if any one installed them and how hard it was or will be?

 

I haven't installed an underdrive pulley but I had to remove my pulley because of my supercharger. The hardest part is getting your hands on the right tools. The crankshaft pulley on 2007-ups do not have the three threaded bolt holes that most harmonic balancer pullers could be used to remove. OTC makes a puller that doesn't rely on the bolt holes. You could try some of the auto part stores that rent tools. You may have to remove the fan and shroud for clearance. I had to anyway, but I'm not sure you'll have room to work with the fan and shroud in the way. The fan is going to take a special tool to remove as well. Beyond that it's a matter of removing the belt and installing the new pulley. If you have other pulleys with the kit, I can't help.

 

Go to any parts store ( tell them what your upto )and rent a 57mm spanner to hold the fan pulley at the screws, then I used a 1 1/2 oppen end wrench to lossen the fan.
If you dont allready have one youll need a shorter belt, 1" I think.

 

i dont think i need a new belt from what ive seen from steeda but ill look into it thanks

 

where did you buy them from? I don't see any parts for f150's on their website.

 

there for the 05-10 mustang gt i called them and they said it works

 

oh, i guess you have a 4.6 then?

 

nope 5.4

 

ok they are on the water pump pulley was a little bit to big so i had to grind some from the block took 3 secs and i did need a new belt and they work great now

 

What Part numbers from steeda did you use? if you dont mind. Was about to order mine from Troyer and would like to compare before i buy.

 

awesome. any performance difference on the butt-dyno?

 

butt dyno says yes and the ear dyno with the off the line burn out is alot longer too have not seen any mpg yet but i also have been driving like a bat outta hell
