Are the factory arms for a Rubicon longer than possibly an X or Sport?

 

Short answer = nope.

Same part numbers.


.

 

Shocks are the only real difference in suspensions.

 

I thought spring rate is different on Rubicon models.

 

no that has been disproven over and over but it will continue to pop up no matter how many times it has been disproved. A stock sport 4 door can have higher spring rate than a 4 door rubicon. My 2013 sport had 17/59 my buddies same sport had 19/60 my 14 rubicon 4 door had 18/60 another friends rubicon has 17/58 these all have tow package autos with hard tops so all over the board.

 

In the 2007 parts manual there are 19 different spring part numbers. All 19 are coded for all variations of the JK: LHD, RHD, two door, four door. There is no coding used by series (Rubi, Sahara, X). There is an additional code, Z??. There are 38 unique Z?? codes. The manual says to refer to the VIN number sales code listing to interpret the Z?? codes. Thanks, jadmt, I was under the impression that the Rubi's had slightly stiffer springs!
