I was wanting alittle extra lift in the front of my kj. I decided to go with the Rustys front coils since its a 2.5in lift and my OME lift was only a 1.5in lift.

When the coils were put side by side, they were the same height. The spring rate of the OME's is 375lbs(or so Ive read) and the Rustys springs are 310(says it on rustys site).. So how the heck did I get more lift with the Rustys springs?

So far I have right at 1.75in MORE lift over the OME's. Thats with two conduit nuts under the clevis(had two with OME springs also). Im hoping it will settle down to right around 1in more lift over the OME lift. I dont really like how the CV's look right now. That would give me right around 3in of lift from when I was stock..

JK man I dont have a clue but I would think that it has to do with the way the springs are made
the OME's could me more/less progresive where as the rustys are the same through out the spring ?

what I am getting at is that at rest they are the same but the rate of the OME's is different than the rustys so that when you apply a load to the OME's they sink more than the rustys wich may be the resualt of a better or worse ride?
Just a guess but I dont know but I plan on finding out one day

Either someones ratings are wrong or like jason said, the rusty's are a progressive rate spring. Did they have the same number of turns, wire diameter etc....

Might be a good idea to remove those conduit nuts till you see how much things are going to settle.

Hows the ride?

Ive not driven it yet. I got done with it about 9pm last night. Im going to go find some big dips this morning and try to break them in some. :twisted: Ill get back to ya after I take it for a drive.

The CV angles are noting like they would be with the Franken lift, but I still want it about 3/4in lower. It doesnt take me that long to get those conduit nuts out, so its not that big a deal. Im just alittle tired right now and really do no feel like doing that. :?

I guess someone has the spring rates messed up. :?

Aight, I drove it hard with some good hard braking and dips.. Here is the CV joints after one day.

It dropped down to right at 10"(from the point I measured, not to the skid).

I have around 9.25" under the skid. So I gained right at 1" going to the rustys coils. Im happy. 8)

The Rusty's springs will do a significant amount of settling. Your CVs will be much better after.

Did you need the clamp on rubber piece for the rusty's coils?

I didnt have upper balljoint contact with the amount of clevis lift I did(coils turned to where the upper balljoint goes between the coils). However, I do not like the angle of the balljoints at full droop. :wink:

Jeepjeepster, where did you measure at under the skid to come up with the 9 1/4 it looks like the drivers side right as it flattens out from the front is that about right? And you have the Mopar skids? Also you have the 245 70s on now? Just went out to measure mine I have a little over 10 1/4 at about that same place on the raised portion and over 11 1/4 in the other areas just trying to get a feel for how high mine is compared to others.

I took a pic of it, its the third pic down. :wink:

I measure at the lowest point on the skid where its rounded. Yes, I had the 245/70 tires. I cannot believe you have that much under your skid! Do your cv angles look worse than mine? Thats what you really need to go by.. Everyone measures from different places and get different numbers. 8) The type of terrain your on can also change the measurement.. Even if it looks level, it can get way off. :wink:

Mine (cv angles) looks almost like yours. I measured it just a little bit ago sitting on a competely flat floor in the garage so no leaning or uneven ground. I just wanted to make sure that our tires were about the same height, and also that you had the Mopar skids as well. Thats why I asked because everyone does measure at different points. OK so now I sort of know how high (or low) mine is.

Thanks

Tom

Looks Good

Did you rig that clamp/bumpstop yourself? If so, what did you use, if not where did you get it?

How did you turn the coils so the UBJ goes between the coils? Is there a way to do this while the coil is in place? Do you just keep something loose?

I ask because I'll be adding a lift shortly and want to try to avoid UBJ contact at all costs, without much extra cost (i.e. new arms).

Jeepjeepster made the bumstops himself if I remember right. I dont have any upper ball joint contact with the OME Heavy duties and Rancho struts, but also have 4 conduit nuts under each side. I am just about as close as I would want to go without touching. I can barely get my little finger in there
