4DR Rubi with tow package is the tallest out there. IIRC, they end with either 18 or 19 in the front.. .can't remember the number for the rear.
As Rich mentioned, putting them on a stock 2dr will get you about an inch taller, potentially allowing you to install a 33" tire.
doesn't matter if it's rubicon or not on springs... just the options... my wife's '09 X unlimited with hard top and tow package had the highest tag number springs available (don't remember #'s off top of my head, but there's a thread somewhere about the stock springs and the numbers on the tag)... i put them on my 2-door rubicon and got at least an inch out of them.
it's the shocks that set the rubicon suspension apart.
oops... and forgot what forum i was in... lol.. so... question for seller: what are the numbers on the tags on the springs?
