Hitting bump stops changing springs?

Good Afternoon:

I currently have a JKUR 2013 with RK 2.5 with all the arms. My jeep has turned into more of an expedition rig and has gotten heavy. When roof rack and family is loaded up I can have some bone breaking hits on the bump stops. So I am thinking the answer is going to the RK 3.5 springs. I won't have to change anything except springs and adjust arms. Would this be best approach. Thanks.

Do you have an aftermarket front driveshaft and high steer kit currently?

If not, maybe just rear coil spacers is the way to go without going down the rabbit hole.

Driveshaft is a good idea at that height. I didn't need a high steer when I had the RE 3.5 but did when I bumped to 4.5. You wouldn't know until the springs are in because of variances between vehicles, so be prepared to buy one in case you need it. Also do your shocks have enough length for compression and extension at the new height? Is it bottoming out in the front and rear? If only in the front and you are otherwise happy with your current lift, you may want to think about hydraulic bump stops like King has. They would cost about as much as springs. The back ones are much more expensive and require welding, so that's not much help if you bottom out on the rear bumps.

EDIT: you posted you have the drag link flip as I was writing this so... nevermind.

Not sure how much an additional 1" lift will do -remember rule of thumb is to extend bump stops same height as the lift your're installing. You'll be taller but still have same problem.

I'm in the same boat as you. Loaded down my ass is dragging and hitting the bumpstops hard. Unloaded no issues whatsoever. I'm considering trying out a pair or Airlift bags for the rear only when we go on trips or when we get our trailer. I don't plan on using them under normal unloaded conditions though. Might be worth looking into. :idontknow:
