I think you would end up with maybe a 1/2" or so. Putting them on a 2dr is where you would really see some improvement since they're so much beefier than the 2DR base model springs.
Thanks Dan. I was looking at the Rock Krawler 2.5" Stock Mod which consists of 4 springs front track bar and rear track bar relocation bracket. Was wondering if the Rubi springs would provide at least 1.5" lift but sounds like it is not gonna happen with the 4-door.
I know the 19 front coils and 60 rear coils get you a 1-2" lift on the base sport models. Swapping out my springs for them on Monday along with 1 3/4 Daystar spacers. Paid 155$ from Jeep for all 4. Good cheap way to get a little lift in my opinion. Also got rid of the junk shocks that came with my 2010 sport and put on some Rancho 9000xl 4" lift shocks today. What a difference in ride control, much more control and a sturdy feeling. Cant wait to get the lift on so I dont have to worry about bottoming them out.
