Absolutely if you see yourself making some changes the double adjustable really facilitate that- I’ve seen both sides of it-
....Double adjustable get loose and rotate
...Single adjustable drive you crazy when you’re trying to fine-tune
....I got my hands on one that had bad or no axle alignment done after a lift....With double adjustable I was able to correct everything in under an hour.
You've actually had a DA arm loosen up? Oddly enough the only jam nut I've ever had come loose was my Currie track bar, which obviously is a single-adjustable link. I tighten them all with everything my 175lbs can give it through a 24" breaker bar.
