I posted a link in your thread. As mentioned tightening the jam nuts is a PIA.
I would get a hold of a 1 1/2 crowsfoot attachment. I found it to work the best.

RK has The front lowers at 23 1/8,

rear lowers 2 door 19 5/8 (stock = 19 3/4 ) 4 door 20 1/8"
I would set them to 19 3/4 on either and be done.

 

Great looking setup! Is there anything else needed to run these springs? This is something I would like to do with my jku.

 

I run the same set up. All I have are the recommended bilstein shock, brake line drop brackets and rk sway bar discos. I will be adding 1" bumpstops soon. At the bare minimum you can run just the springs, shocks and drop brackets.

 

Very happy with the Rock Krawler 1.5 lift.

Installed Rock Krawlers front and rear coilovers

 

RK 2.5 stock mod and Bilstein 5100's with 35's and flat fenders. So far I'm real happy with it. I'm going to order some front Teraflex sport LCA's soon. The fender liners have been installed since this picture was taken.

 

awesome thread....I love the pics and info about rock krawler. Those running 3.5" lifted 4drs, is the front driveshaft a "need" or ok to stay stock and upgrade a year or so down the road? Basically I'm trying to make sure I don't cause the domino effect immediately by going 3.5 over 2.5. I'd rather get in on 3.5 flex system, then go to other things and come back to drive shaft and upgrading the suspension further after everything else was addressed

 

Just put my 3.5 on yesterday. Loving it. Front driveshaft is next on the agenda just to play it safe.

 

Finally flexing out the coilovers.

 

I ran with the stock drive shaft for 3 months and it was fine. Depends on how often and how hard you wheel your jeep. It should be fine for a while.
