My father wants to add some to his 2004 supercrew.
Anyone installed these themselves?
Is it difficult? Any thing more thatn a wrench needed?

Thanks

 

They are not hard to install at all but some places will install them for free when you purchase them, at least the place I bought them from did. If you are looking at the internet to purchase then do not worry about the install. Basic tools and you can do it.
Hope this helps.
