i got my lift kit from bds suspension - they use a thread on extension for the top of the strut - 2 inches long and i think they are available separatly from the lift kit

derek

I called bds and they wanted to sell me the struts and the spacer. So I don't know if you can get the spacer seperate or not.

i made my own as well 2"strut spacers. i havent had any problems yet, been driving on them now for about 3 months. and i beat the crap out of it. there is one other thing you can do to get a little more travel (down travel).take the lower ball joint and flip it. it sits under the a arm know put it on top and it will give you about      3\4"more down travel. i am as high as i can go with out going sas.
