Do i need struts with OME lift

I got my 885's and aal. Installed the aal no problem... got 3 inches (i know its gonna settle). My problem is know when i went to install my coils, i could not compress them to fit my stock shocks. Im gonna obviously have to replace them. I was hoping they would fit to hold me over til spring. The billy 5100 is obviously the way to go. (spend 5 minutes on these forums and youd know this) Long story short is how exactly do they work? I know they have the little collars on them for the different ride height but where would i set mine

 

So true, but still you will find 5 different threads about the same thing. Just to clarify stock height on 5100's is the lowest notch.

 

But as you may know already, OME shocks go perfect with OME coils. But 5100 are definitely the way to go budget wise.
