Are Rock Krawler spring shims compatible with Rubicon Express springs?

[Jkyle]

I just purchased a 2012 JK Rubicon 2DR. The previous owner installed a Rubicon Express basic lift with 2.5 or 3 inch springs but left the control arms stock. I want to upgrade the control arms with Rock Krawler X-factor Mid arms.

Does any one know if the Rock Krawler spring shims, that come with the control arm kit, are compatible the Rubicon Express springs?

I see no reason they wouldn't be as long as the springs are the same length.
