Cornfed. They sell a 1/2" spacer that goes on top of the strut, no strut disassembly, no stud replacement. Comes with its own nuts that work well for the size of it.
The 1/2" spacer nets you 1 inch of lift due to the suspension geometry. They call it a 1" leveling kit I think. Done.
I have had them on mine for a while. I'm happy with them. That's all I run for any "lift" on the Yota though.
