Also, front has caster/camber in the plates... Nice feature. The height adjustment is in the knuckle, so you set the spring tension with the jam nuts, then set your height.
Oops double tap
I think they are still under warranty... Not even a year old. Not sure about specs, i got them for the price, so i never looked.
They ride decent, and they are quiet. If i was staying low, i would never sell them. They were worth every penny.
