Exo k4 vs kifaru ark Which one is more stable?

[zhangfeng]

I have no way to try these two frames, so I want to ask if there are any brothers who have used these two frames at the same time. Which one is more stable? I don't want to shake on my back. What's the burden on my shoulder?

I found the ark more comfortable. It takes more adjusting to not feel it is pulling backwards compared with the K4 though. I found the Ark slips less on my hips.

I would say that has more to do with how you place the load and strap/compress the load then the actual pack. You can make any high end pack “shake”on your back if you load it incorrectly.
