Nope, inside they are the same...
Most Rubicons were built with more options than the x's were, however.
When I bought mine, I couldn't find one without a 6 disc changer and dual tops.
I would hope so! The X is just an SE with a 4.0. The Rubi is a top model (like a Sport for example) with most everything already included, and with some substantial upgrades not available on a non-Rubi (as mentioned in this thread.)
In the early years of the X, not much was available even as options. In the last years, dealers ordered lots of X's so optioned out they cost nearly as much as Rubis. Poor suckers who bought them knew no better...
Okay, I should search for the answer to this, but since we're kind of on the topic already...what's the deal with the passenger seat tumble feature? Is that an option, or standard? I know it sounds kind of stupid, but I'd like to get rid of it. Could I pick up a non-tumble bracket, perhaps?
WHY on earth for? Just don't tumble it. <slapping forehead> And no, they all tumble, there's no non-tumble base.
I was told by both Rough Country and Jeep (DC) the springs in all TJ's (ie; 2003 - 2006) are the EXACT SAME SPRING. Check the part numbers for a 2004 Rubi and 2004 X. Their the same. Where the difference is is in the axles. The D44's front & rear on a Rubi sit 1/2" higher than axles on a Sport or X model.
For example, if you were to buy a 2.5" lift from Rough Country, on the Sport and X models, you will achieve 2.5" of lift, where as on the Rubi, you only get 2.0" lift due to the axles - not the springs.
You are incorrect about the difference being the axles. The D44 rear in the Rubi is the same housing as the D44 in any other TJ (I.e. the same except for the locker and gear ratio.)
And the statement "the springs in all TJ's (ie; 2003 - 2006) are the EXACT SAME SPRING" is incorrect, and well known to be incorrect.
I inquired thru (email) Jeep technical owner support from the Jeep site. Someone got back to me a day later stating the springs in my '04 Rubi (4.0 / auto tranny) are the same as a equivalent equipped '04 Sport and X model. .
That is correct. But it is NOT what you wrote above. IF an X and a Rubi were equivalent equipped
, they'd have the same spring rate. This is not
the same as saying all TJs have the exact same spring.
