Hey friends, I have a 2011 JKU with a 3” lift. I added steel bumpers, a gobi rack and a spare tire holder (+tire) and, not surprisingly, that’s a lot of weight—especially in the rear. I have a large roof tent on another rig that I’d like to move to the Jeep, but I’d like to address the suspension first. I love the look of larger lifts but practically, 3”-3.5” on 35” tires works well for me.

Any advice on the best way to address this? I drive it hard off-road and I want suspension that can handle the weight, take trail punishment and keep it even.

Here’s a pic that shows the current stance.

I had the same issue with our jeep. ARB awning and a RTT left a big sag in the rear. I went with the overland springs from Teraflex and took care of all the sag. My understanding is that the OME heavy duty springs will work as well.

I have the exact rig and the OME heavy springs took care of the problem. I had put on the OME medium springs but they didn't last.
Here is a picture of before and after, the rig is level when towing and a little higher in the rear when not towing. Rides like a charm.

On the OME springs. I had them on my overloaded Rubicon and now have them on my 80 series. Spring spacers will not keep you from bottoming out.

Thx @MOAK, so you’ve found that the OME springs have been helpful?

Yes, very much so. When loaded down with and all our gear the vehicle scales out at 7,000 lbs. that includes about 150 lbs of tongue weight for the 1,000 lb trailer. All told, 8,000 lbs. the cruzer drops about 3/4”. The rubicon did about the same. Be mindful though, your truck will ride like a truck when not loaded. A lot of folks don’t care to make that compromise. ( 2863s in rear, 2850Js up front)
 
Same issue with my AEV 2.5" lift. The rear just needed more stiffness to deal with bumpers, roof rack, tire carrier. I'm 300lbs. My dog is 175lbs and a Jeep full of gear made the rear end soft. I moved to Metalcloak Progressive springs and it made all the difference. As a daily driver, it is a bit stiffer, but worth the tradeoff.
