I am already worried about too much ride hieght gain and too stiff springs harming the ride- why do you suggest the 6 leaf? I am guessing the rear end is currently sagging about 2-4 inches lower than stock, and these raise the rear end 2 inches according to the description, which could mean as much as a six inch lift from where it is now to the rear. The six leaf version is for the BB dart after all?
