Then all you need is move the 6L links closer to the central joints and experiment with placement and angles of the shock absorbers. Or you can try the setup from my Baja Truck's rear axle, which had plenty of flex, as shown below. And no, it doesn't come with instructions.

Using 6 stud links may restrict articulation, so scaling down the crawler may be advisable. What size tires were you looking to use?

My current build has 16l parallel lower links, 9l triangulated upper links, and 2x 9.5 springs in series per corner. Great flex and it even has droop.

A long time ago I did something like this on a buggy but I don't see why it can't be adapted to a crawler:

Here are a couple of pics of what I was talking about.

Using the torque balls (mog parts) is a great solution. There is a reason that Lego went with it for their 9398.
