i am at 5.5" with RE non-adjustable short arms and i can honestly say i have no problems with the ride, handling, and death wobble.. actually has less harsh ride than my DD with 3" lift... ideally i would go with adjustables but i honestly dont see a need to mess with my current set up right now.. i do run it on the highway at 65mph as well, and that is limited by some front d/shaft vibes which might go away with some adjustables too... it is mainly a trail rig but it sees DD duty a few days a week just for the hell of it... my next step will definately be a CLAYTONS L/A set up...
