Sounds like your front end is 'hunting' which may be a product of the alignment. There are different shocks and springs. Take a close look at your KYB's, there are the GR-2 which are gas but softer and there are gas-a-justs which are gas and more stiff. Count your rear leafs to see how many leafs there are 4 -4 1/2 are comfortable to most, 5 leafs are stiffer/performance vs. ride quality.
Look at the inner shock towers and see if you have an extra pair of holes 1" above where your UCA bolts stick through, they may have performed the 1" shelby/arning drop and didn't use the necessary alignment settings for this mod.
I've also had shops do an alignment and not even tighten the front strut rod nuts, take a look at those bushings also.
