Does anyone have any experience with dual rate coil springs?

[Wcampbell40]

I have been doing more a more serious off roading over the past couple of years so I have been upgrading what I see as short comings as I go. I am now looking at front coil springs. My 2012 jku had a Zone Offroad 4 inch lift on it when I bought it and it doesn't flex well at all. I have front swaybar disconnects but the springs just seem not to compress. I also have an adjustable track bar and track bar relocation bracket.

I have been reading about dual or multi rate coil springs and I'm thinking they might help. Does anyone have any experience with them? If so, what brand should I be looking for?
Thanks in advance for the help!

Oh ya, I also have control arm relocation brackets that I will hopefully be installing tomorrow. I am planing on upgrading to long arms eventually but it's just not on the budget right now.

This isn't the solution to your problem.

Zone is a pretty low end lift for starters. In addition, when choosing a spring and shock setup, you want something that pairs very well together based of compressed lengths, free lengths, etc. This is the reason that the Currie springs and Fox shocks are so beloved on the TJ platform. The numbers of the two work extremely well together when properly setup.

In addition, for more flex you'll want to consider getting rid of the factory front sway bar and not running disconnects but instead running a Currie Antirock system. This will improve your performance tremendously.

Also make sure that you have a 50/50 up-travel / down-travel bias with your shocks, otherwise you are hurting your performance. If I had to guess 9 out of 10 Jeep owners not only have no idea what this means, but also have no idea how or why it's so important.

Unfortunately I'm becoming clear on zone's quality. I've been reading about shock lengths and travel in them. When I have tested the flex the socks are no where near bottoming out, that's with the zone shocks that came with it and the new Ranchos I just put on. That's why I'm thinking the spring rate it just way too high for what I want.
Also the antirocks are definitely on my list for the future!
