Two Part Question - ABS Sensor and Ride is rough
 

I have a 2015 F150 2WD. I recently put a 3" front and 2" back leveling kit on it. Before I did this the ABS sensor for the front left malfunctioned from hitting a pot hole at roughly 25mph so I dropped it off at a Ford Dealership. They clarified it was in fact the ABS sensor and proceeded to replace it. When they ordered a new one they said the new one was roughly 3" too short. What would be the reason why it would be too short? The one on the right side is the original one and still connected and the front truck is not unlevel. Could there be other issues under the truck that got messed up?

Also, at high speeds my truck does not ride smoothly, my whole truck shakes(not bad) but enough to beat you up and make the drive uncomfortable. I have 305/55/20 All Terrains, I've had them balanced. What could be the reason
