Fun stuff, but still doesn't answer my question. Obviously there's an issue or there wouldn't be so many people talking about it. In more than 10 years of running AE vehicles, IME if there's a known issue they will usually issue a running change to address it. I'm just wondering if they've said anything yet. And no, haven't noticed anything about the stiffness of the stock arms. Don't have my truck in hand yet as I've said several times. If the RPM arms handle the same as stock, that's awesome, they're damn near unbreakable. But AE wants you to buy their stuff, so I'd look for a change to the stock arms LOL.
