I have a D2 with 2" lift OME HD springs and shocks. I run without the bars on trails. I find it helps articulation, reduces head toss *a lot*, and increases traction. Even when you're not at the limit of articulation, removing the swaybars helps keep the weight more evenly spread on all 4 tires over milder obstacles.
This past weekend I ran without the front and rear bars for the first time. Previously I only removed the front. My ABS/TC system is not working, and I was really surprised what I could drive over with no traction problems. Even without locking the CDL.
However, I for one do not like driving on the road like this. The truck feels very unstable. I don't even want to think what it would be like to be in an emergency situation like this. Yeah, you need to know how to drive it, it goes like this: "If anything is in front of you on the road, just crash straight into it, don't even think about swerving." Doesn't matter if it's a deer, a child, or a Mack truck.
Sure, running without bars on the road is perfectly fine 99.999% of the time, if you drive carefully. For me, it's that 0.001% of the time I want the bars.
Quick Disconnects are on my short list. For now, I take the bars on and off as needed. It's super easy on the D2.
