I am thinking of changing my 2" rusty springs to the Rock Krawler 2.5" springs. I have the Bilstein's 5100's with the RK adjustable front track bar with the JKS adjustable sway bar links, am I going to need anything else but the springs? The reason i am doing this is I have a Rock hard front bumper with a winch and just bought a ACE rear bumper with a tire carrier and the rusty's seem like they are sagging a little.

Thanks, Kevin

 

You probably won't need to do anything other than swap the springs. The only 2 possible issues you may have are brake lines, and rear track bar. The brake lines with a 2012, you should be fine, worse case is you may have to add an inexpensive set of brake line extensions. The rear track bar, especially with the ACE bumper on the rear, you should be fine, if needed you can add a track bar bracket after you have the springs swapped out.

 

As mentioned the brake lines should be extended or get the relocation bracket ($30) for the rears to be on the safe side. I would get the rear track bar bracket ($100) that goes on the axle. Other than that I think you will be OK

 

Thanks guys! I was talking to a vender and he told me I may need to put lower control arms on or front caster/camber brackets on to correct the caster, but he also said that can be done later. should this be done now or later or at all, this is only a 2.5". On my 08 JKU I had the teraflex 2.5" and didn't need them.

 

Need to do now... No.
Need to do later... Maybe. you'll have to see what your angles are after the lift settles out.
Can do now... Sure, even at 2.5" your caster will be out a bit, and adj. arms (or brackets) will let you dial it in perfectly. Rear pinion angle should be OK on a 4 door. 2 door, you may ant to do the rear UCA's.

 

Ok, Thanks Mike for your help!

 

No problem, that's what I'm here for.
