Don't take this the wrong way, because I appreciate everyones input, but did you read my original post?

Im not trying to be a jerk I promise, I know the photo was larger than the typing. The only reason I did the RTI at all was to go up backwards and see what was stopping my springs compression.

I have had my Jeep on the trail quite a few times since my tera kit install. I was noticing that on the rocks sometimes my rear was not sucking up the rocks as much as I wanted. so I rolled it backwards up the RTI. The kit works well don't get me wrong. On my TJ the spring rate was particular to my jeep/top type So the jeeps rear spring would compress to the bumpstop before the jeep started teeter-tottering. That is what I want this one to do. For the type of offroading I do (mostly slippery arkansas rocks up and down mountain) It would be better for me to keep my jeep as level and let my jeep do all the stretching. I don;t know how the trails are in your area, so your needs may be very different than mine.

There is nothing wrong with this kit, and it does not have stiffer than necessary coils or anything. They designed this kit to be able to give a 4 door hardtop with real bumpers, swing away with a full sized spare, to have 3" of lift. I assume they also designed it to have at least factory load capacity. That does not mean that the springs are to stiff for a two-door or anything. I would just like to try some springs that have a lighter spring rate. I have a 2 door, and I never pull a trailer, rarely have anyone/anything/ or even much gear in the back.

I started this thread to make sure that I was not missing something crazy and it was just my spring rate keeping me from doing what I want to do. Many heads are better than my half of one for sure. Thank you all for all the input. I am not taking offense to anything so feel free to tell me I am wrong in my thinking or whatever. Thanks again.

 

It's because your front sway bar is disconnected, there's nothing wrong with your rear suspension.....re-connect the front and try it again and you will see much different results.

When the front is disconnected, that's where you'll see most of the flex...

 

haha sorry dude, yea i kinda just looked at it my bad. I've always experienced a lack of rear axle droop, even with the stock suspension. Rear stuff has never been an issue though, so that is kinda odd. I still agree with redneck though, at least regarding that when your on the ramp it might not stuff. I'll do a reverse rti this weekend and snap some pics, see if we can figure this out.

 

Here's mine way back when i first got it....


front connected on the same type of incline (sort of):


notice how the rear is stuffed?


same spot, but front dis-connected:


the front is doing most of the flexing

 

Put a couple fat chicks in the back. haha

 

Yes....Its because your front sway bar is disco. The front axle is doing all the work (flex) since its disco and less resistance. The rear sway is doing its job and causing the no stoff effect.

 

Bwaahahaaahaa!!!

 

we have the same lift, and almost the same jeep... so don't worry about ramping it. I think you will have the same result. I don't think anything is wrong with my jeep or lift, it just has firmer springs than I need.

I agree with some of that. That is a really interesting point about the sway bar disco. I don't really think that you completely get what I was saying though. The TJ I had right before this, and the grand cherokee I had both had coil suspensions similar to the JK's and I lifted both each more than once. they both would compress to the bumpstop. I just put the JK on the RTI to see if anything was binding up or hitting or something. The issue was that when I was on the trail the rear is not compressing and "stuffing" the rear tire on the trail, it is moving upward very little really. When my jeep is on a level spot and the jeep is level, and I drive one rear tire on top of a rock I would like my tire to move upward and the jeep remain level. Right now if I do that the jeep gets kinda tippy feeling and almost like it has no suspension at all cause the jeep tilts. Neither of my coil spring jeeps in the past did this, but I spent some money on them and I think both of them weighed a bit more than this.

The front does not do that. The front has a heavy engine sitting on it though, and like you said the sway bar is disconnected so it flexes more than usual. But think about this... the swaybar kinda works like a spring, just like a torsion bar, when it is connected. As the bar twists it applies pressure to the axle. when it is disconnected that extra pressure is removed. If you think about it the swaybar really is the same as having an increased spring rate on the spring that is being compressed. The jeep stays more level and less tippy when the swaybar is disconnected because of the reduction in pressure between the axle and Jeep, allowing the tire to travel upward into the fender well instead of pushing the jeep up.


The swaybar in the rear doesn't put that much pressure on the axle under compression like in the front because it is much smaller and has less spring rate or whatever. I think that a reduction in spring rate in the rear (by getting springs with a lower lb/in rating) will give me the compression I want back there and keep the jeep more level. Just like disconnecting the front swaybar.

I really appreciate everyone who has taken the time to respond to my question. I hope everyone who reads this understands that there is NOTHING WRONG with my suspension. I am very happy with my jeep and suspension, I am just looking to improve my offroad performance. The only reason for this thread was to make sure that I didn't do something dumb, or that I was missing something on my suspension before I decided 100% that this is just from my jeep needing a lighter lb/in. coil spring in the rear. I hope no one sees this thread and thinks something is wrong with this kit.

the front shouldnt have anything to do with rear stuff. the TF springs just dont stuff like others do, but they should stuff more than that.
