I called Eibach tech support yesterday to ask them why their Pro Kit did not lower the rear of my car, but did lower the front. One of his suggestions was that maybe the SRT6 shocks had bump stops in them, witch I ain't buy'in that. Another suggestion was that the top spring cup was too thick, but it was the same thickness as the front, so I a buy'in that one either. His last suggestion was that if I tightened the lower control arm bushings while the car was in the air with the springs extended that could be the problem. This one is a very slim possibility, but I still really don't think so. The rear Eibach springs were about an inch taller than the stock one's and the front was about 1/2" taller than the stock one's. I know that the Eibach spring coils were not as thick as the stock one's, so that didn't concern me when I was putting the in. Does anybody know if the SRT6 shocks have bump stops in them? And does anybody know if the top spring cups are thicker than a regular Crossfire? I'm going to be calling the dealership with these questions sometime today. The tech also said there is no settling time on the springs, and that when you put them in the car is going to drop as far as it's going to as soon as you set it on the ground. EJ this one would be a good one for you, you seem to come up with a lot of spec's for these cars.
Thanks in advance for any suggestions,
Steve

 

The only thing I can tell you is that he's right about tightening bushings. It is common practice to tighten suspension components with all four wheels on the ground. I even take it a step further by compressing and releasing the suspension a couple of times before tightening it down. You can even have someone sit in the trunk while you tightening it.
IMO that would be the first thing I would try. Good Luck.

 

I was thinking the same thing, they are compressed right now I have 6 concrete blocks in the back. I just got off the phone with a dealership, I had asked them if the SRT6 upper spring cups were taller than a regular Crossfire. They could not give me an answer, but he did say there were 3 different part #'s, but it gave him no measurements. So now I'm searching the web trying to find these part #'s to get some measurements.

 

Steve, did you double-triple check to make sure that the bottom end piece of the Eibach spring fit perfectly into the car's bottom spring mount groove slot?

I did not remove the rear shock so maybe the bump stop is at the top of the shock mount location inside the trunk.

I noticed that my rear top spring pad was #3. But my rear drop was nearly equal to the front because I have about 60 pounds of stereo equipment in the trunk and the max drop happened right away.

Rear

A 210 325 04 84 (17mm)

Yeah, I made sure that the bottom of the spring was in the notch and that the top was in the right place on the isolator, (cup). I just removed the bottom bolt on the shock, but as far as there being a bump stop in the shock I find that hard to believe. I put 6 concrete block in the back and it lowered it 1 inch, if there was a bump stop I don't think it would have dropped an inch with the blocks, also you can push down on the car with your hands and it goes down even farther. The part #'s Chrysler gave me for the spring isolators were 5102308AA, 5102311AA, & 5102312AA. I called a bigger dealership in Maine and with my VIN# he was able to tell me that my car had the 5102311AA, but could not give me any measurements.

 

I think H&R spring has more options on spring pads.

 

I've made an appointment to take the car to the dealership next Thursday and I also talked to their alignment guy. MI1XRIRE, you may be right the alignment guy said some cars it makes no difference if you tighten the bushings with the car raised and some it does. So I'll probably give that a shot first, but I got to get this thing right before I take it in next Thursday or if I can't get it down maybe it won't look so bad with the rear being a little higher off the tire's than the front.

Is there a bump stop in the SRT6 shock? The Eibach tech said he thought if I took the shock out, took off the dust cover I would probably find a bump stop that could be removed. But I find that hard to believe.

Not yet, but I think I'm going to jack the car up and set the rear tire's back down on a couple concrete blocks. Then get under the car and loosen up the sway bar and all the bolts on the lower control arms with the weight of the car on them tonight when I get home from work.

 

Well I took the 6 concrete block out last night, pushed down & lifted up on the rear of the car and it has dropped 1/2". I went ahead and set the rear tire's up on blocks, (put 3 blocks end to end giving me 4 feet to run back & forth on) with cardboard between the blocks and tire's so that the tire's could move, loosened all the lower control arm bushings. I drove back & fourth 6 times, got out of the car, pushed down on the rear of the car, got back in and did it over again then tightened the bushings. When I let the car down I drove it back & forth in the garage to get the wheels out of the bind from being lifted, then measured and it made no difference. I went ahead and put the blocks back in the rear of the car and I'm going to leave them in there for a few more day's.

 

Man I don't know what to tell you, did Eibach verify that you had the correct springs for your car,
I would ask for free standing height, number of coils, coil diameter and spring rate if you have someone that can measure it.
Did you try AL suggestion to disconnect the sway bar?
Good luck at the dealership today...

 

I looked over how the sway bar connected to everything and the way it's connected I don't think it would make any difference. Actually I had to pull the sway bar connecter down and jack the lower control arms up as far as they would go to get the bolt back in. I checked the #'s on the springs to make sure they matched the kit, after what I did & seen last night I think it's going to be okay on the rear drop. I might not get the full 1.2" that the kit said, but I think I'll get at least 3/4" drop or more and I'll be satisfied with that. The car's not going to the dealership till the 5th of July for the alignment.

Thanks for your input,
Steve

 

Steve, one other thing, have you actually driven your car since you replaced the springs? Maybe those new springs need a good workout to settle down? I don't think it would hurt your tires too much to drive it a bit before you can take it in for the alignment.

 

I kind of thought that may help, but it's been raining every day since Sunday when I finished the install. I'll be getting out for a drive in the next day or two, it's suppose to be nice by Friday, in the meantime I'm leaving the 6 concrete block in the back.
