Heavy JKU spring options

[desertrunner]

For the sake of conversation what are some good coil options for heavy JKs 6k+ ish lbs? While the AEV coils work I'd prefer something that feels more consistent and smooth. But what I will say with the dual rate is loading up a heavy JKU it doesn't sag.
Not sure if anyone makes a good true progressive rate or even a stiffer linear that doesn't sag like the plush rides. Just maybe something that would work as alternative to a dual rate for a heavy JKU.

My JKU is 6400 pounds +/- on Synergy springs. I don’t have a lot of experience with other brands, but I’ve never been unhappy with what I have. It’s been 7-8 years and there’s no sagging.

I went from AEV to metal cloak to synergy with a similar weight.

While there were time gaps and other changes made along the way I like the synergy coils the best so far. I’ve stopped the search for “what’s next” after them.

I've been really happy with my OME rear springs.

Currie makes a 4" + spring that I ran in the rear and I was really happy with them. Unloaded you'll sit a little high but with the load in it sits perfectly.

I think I'm gonna make the switch to the HD ones on my 2dr actually. I have their med duty ones and they are a great unloaded ride but as soon as I put that tool box in the back its squating a bit.

Yep. I ran the medium duty for 1 New Years run. Ordered the HD springs as soon as I got home. [emoji23]

Even now that I've lightened the weight in the rear, Fiona still rides well unloaded and when we had her loaded up for a week in the desert it was great.

I like the way a bit of rake looks, so I'm happy all around.

I have had the metalcloak dual rate coils in the rear for about 3 years, no sagging. I replaced the front metalcloak coils with the evo plush ride coils and love the setup for now.

Anyone try out the rancho progressive rate coils?

Sharkey has the 2” kit on his Jeeps. I think there is a thread on here somewhere talking about the 2” progressive kit.

Anyone?

I'm running them on my gladiator in the front. Not sure if that helps with your question. But I think it rides fantastic.

I have been running the RK progressive springs for the past six years. They are stiff, but have done very well with the weight of the JK and when fully loaded on and off the road.

I’m running Rusty’s 3.25” springs. Had them about 3 years, the front feels great but the rear are a little stiff unloaded. But feels good loaded with gear, luggage, etc.
Have them paired with Fox 2.0 shocks

I currently have 4” plush rides and I added Air Lift air bags and they are a huge improvement. I was thinking of heavier coils but decided to try the bags. I load up a family of 5, dometic 50 and everything else for camping and it barely sags and I can see out the rear window.
