Just Purchased a Rubi!!!
From looking the pictures I don't think it is a long arm. I have a Tereflex long arm and the control arms reach much further inward on the frame. They are very obvious on a side shot.
If they are grey, you either have a Rubicon Express lift or AEV. IMO if they are grey and your running all Bilsteins TeraFlex arms and 35s your lift kit is the AEV 3.5 lift. Most don't lift to a 4.5 unless rocking 37s. Also Rubicon Express comes with arms usually...
