Hi I recently bought an 04 Escalade for my wife to drive. Bought it of a twenty year old kid who ripped out the shocks and replaced them with the cheapest ones he could find or so it would seem. I want it to ride nice for my wife and am wondering if it is worth putting the electric shocks back in or just to go with the Arnott Bilstein air shocks. It seems like everyone seems to be putting something else in instead of the factory system. Why? What is the best?
