BCR's here. No issues with them after years, I forget how many. At least 3.

They are stiff, but I have them 4 clicks from max stiffness as at the height I have it, more travel will rub the aero kit fenders. Only had to happen once for me to increase the stiffness from only a few clicks from mid on the stiff side. Don't remember exactly how many. I miss the smoother ride, but not having to worry about hurting the aero kit plastics.

I guess I could raise the truck back up and then decrease the stiffness... but I've come to enjoy it the way it is. It's not the primary vehicle.
