Honestly there are a ton of opinions on how you have to do it, and what spring length and weight you need to run. I should have just used the calculator link below and started that way, but i was lucky enough to be able to swap springs at my local ORW, sometimes they don't allow you too. Other companies will let you exchange springs if they aren't thrashed. You can also start by seeing what other people are doing for spring rates, but it will be different because of angles and setups, but it will give you a good start. But you also have to think of valving as you can run a light spring with stiff valving or vise versa really up to you. But it takes time to set up a non bolt on like those from Rebel or ORE. Even those need tuning and adjusting to get what you want. But a custom built setup for your rig is by far the best way to go about it IMO.

I think there was a thread started on here somewhere with spring rates and valving. If not might be a good idea to start since coil over set ups are getting popular.

Check out these links for some great info. He gives you the calculator for initial rates and also how to re check and change.

Thanks a lot Flexy!

I'll dig into this and see where I end up!

Id reccomend to get a longer lower coil also. Say you have a 12" coilover get a 14" lower spring.

Mine is my dd on 41.5s and i love it. Tuning and coil rates are crucial for ride quality. They are adjustable so Essentially could be dialed in to whatever you feel is best but that would take a lot of tinkering to get where you may feel is best compared to others. I've always been told not to tune with coils. Get coils for your ride height and preload then tune via nitrogen pressure and shims. But some may disagree.

Thats exactly what I have read and been told multiple times. Coils will get ride height but ride quality and performance is in the valving and pressures.

Do you have any ride height pictures with wheels on?
This was our trip to the Baja 1000, some gear in it, but this is where it sits. The wife wouldn't let me drive..

For a true daily driver, coilovers give up road handling for flex. You cannot have the best of both worlds. You loose sway control, overall road handling and cornering on the road. You gain Flex, off road bump compliance and overall off road traction etc. with them. So, as I said, If you are using your jeep on a daily basis of long distance road driving / highway driving, and only playing off road on the weekends, then think twice about coil overs.

Which is why ORIs are awesome. No coils, just nitrogen pressures.

I don't drive my jeep in the winter, but my buddy who has the EVO coilover kit says it rides like crap when it gets cold.

I dis agree with this... And also coilover/shock flex makes no sense as they both could "flex" as much. You also make it sound like coilovers magically remove your sway bar.

Only argument i see for a dd with minimal wheeling is the cost factor.

I disagree with this, too. My JK on coilovers is solid on the freeway and handles the corners superbly with minimum sway, yet soaks up the bumps well and articulates great off-road. The system is a little firm below 30mph, but at higher speeds, it rides and drives fantastic.

My only complaints are related to the EVO bolt-on kits themselves. If I get a redo, I'll likely go weld-on, or try the kits from Rebel or Icon. Otherwise, I love the way my JK drives and I'd say coilovers are well worth it.

I disagree also... My wife DD's "her" jeep on coilovers and she hasn't complained once.

It rides much better than the AEV coil lift it was on before.
