It looks like Eibach intends that you set it and forget it, because their website seems to indicate only the front is adjustable.
The logic in making the front adjustable is that customers will have seriously different preferences about how much front lift to have. So they make the front...
A lightly modified Bronco is pretty capable offroad. It doesn't cost a lot to get good sight-seeing and meet people.
You don't really gain much incremental benefit from building a monster truck to run the technical trails, where your vehicle can be rolled by a bad spotter.
The choice for optimizing time and money is to run your offroad tires on the street.
The offroad tires give you more street cred than the "smart" street tires will.
I think you found it. I'm also currently leaning toward Eibach springs and Bilstein 6100 series struts (for the extra inch of downtravel).
Eibach rear springs are progressive, like a lot of the better aftermarket springs.
The only front progressive springs I'm currently aware of are...
It looks like those rear springs might be progressive. If they are, then they're doing it in a different way than others.
If you take a look at the pictures of most of the aftermarket offerings, most of the others' rear springs are clearly dual-rate. Ford might be doing this, but in a...
A small lift is a good idea because of the limitations of IFS.
I think my ideal approach to suspension "lift" would be to aim for a spring upgrade (i.e., dual-rate springs), and then partially equalize uptravel vs downtravel by installing longer struts that give me an extra inch of downtravel...
The tire can jounce upwards a few inches, or droop downwards a few inches. Those are the amounts you want to keep roughly equal.
Equal amounts of uptravel and downtravel up front. The rear suspension has more travel, so those equal amounts of uptravel and downtravel out back will be greater...
It might be worth giving it a try, assuming your vehicle will weigh about the same. Supporting the same amount of weight with the same springs. High-end shocks should be able to manage a greater motion ratio.
The extra articulation improves traction by keeping all four tires planted. Those...
Agreed. The OP's objective of not compromising components argues against further suspension lift. Additional suspension lift would limit articulation. So body lift is the better choice for OP's objectives.
