Coil Springs JK Rubicon to JKU Rubicon

I have an 08 JK Rubicon with PSC BFH front bumper and just ordered my winch. I will be installing a Rough Country front 2.5" rear 2" BB. I've read that I can switch to JKU Rubicon front coil springs to remove the sag but do I need to change the rear as well? or just the front is ok?

Thanks

Since you are only adding weight to the front, I would say just the front. How does your jeep sit now? level? or lower in the front? What number springs are on it now front/rear?

I ran 2.5" RC spacers with JKU Rubicon springs on my 2dr, it was about level with a BFH + winch and rear bumper/swing.

I have 18's on the front of mine, and im using jku rubi take offs on my jku sahara. with the rc bb i sit level maybe a 1/4" high on the front with stock bumpers. If you really are on 18s in the front and are a whole inch lower already, then going with 19's, if you can find them, arent going to make you sit level with the winch on it.

Sorry meant to say I have 15s but looking for 18s-19s. Called local jeep dealership and they said I could order 19s at $48 each. But when I went in they said the could not order parts for a jeep that dont match my vin number... I thought this was very odd. I need a vin number from a 4 door rubi to give them I guess...

I went from 15/16 on the front to 18/18 and gained 3/4 inch, so if you were able to get 18's or 19's you would likely see similar results. Check ebay if you cant find a vin to order new. There are always sets for sale on there.
