If thats what's happening surely the answer is to get a cylinder the correct length or slightly shorter so that locks out before any force is transferred to the ball joint ? If the chain locks at full lift and not before you might as well have a cylinder that does the same, the chain will only stop the lower a-arm falling off, can't see it help the ball joint any ?
I can however see the ball joint taking the brunt of the force on full drop as the wheel will want to continue up into the arch but the only thing stopping it, if the a-arm is on the stopz, are the ball joints, this isn't true for lift as the wheel is actually going down away from the frame and the ball joints only support the weight of the wheel when the A-arm drops to its limit.
Does that make sense ?
