I recently purchased a 08 JKU Rubi, it has a lift which PO said is a ProComp 3.5. The springs seem pretty worn out, so I am in the market to install new springs. I would like to Put 4.5 lift springs instead of 3.5 to gain additional clearance. Does anyone know if there is any difference in the links between the 3.5 and 4.5 inch lift? Could I just put in the 4.5 springs? I know the track bar will need to be adjusted.

Thanks in advance
