I'm pretty sure any LCA's can be used with the ICB's (infact, since the ICB's give you better bite, a better LCA like you have would be reccomended). Do plan on getting rid of your sway bar though. The brackets seem to put it pretty low, and turn it into a problem with catching road debris and uneven surfaces.
There's a few guys who welded the brackets on, but I believe they can be just bolted too. Shouldn't be much modification to installing them.
