Since I can't find the complete answer to my question, I'll make a new thread. Yeah, the search is filled with glorious information, but it doesn't help when your question is vague!


Anyway, I'm getting Eibach Sportlines. They're on the way now actually. I hear they are a tiny bit lower than the Pro Kit. Will I have problems getting a jack under there? Probably, but let me see what your answers will be. I can always pick up a lower profile jack also. Spring isolators- I hear they make taller ones that will decrease the amount of drop... is this true? I'd like to reduce the amount of drop in the sportlines if possible.


And a few side questions; how is your ride quality versus OEM? Cornering and handling? You dig em? Worth the cash?

 

I read on here somewhere, that if you order replacement spring isolators from GM you will get the 4th gen ones, and those are taller. There is a thread that has pictures of the two in comparison. I think it was started by ebmiller88.

 

I have Sportlines and cannot get a standard Craftsman 3 ton jack under the front behind the wheels. A lower profile aluminum jack just squeaks under. A cheapie from the local parts store will also fit.

I have the factory isolators and the rear is a little too high for me. The front is very aggressive.

As to their effect, they are a great piece of the suspension whole. I replaced all my suspension parts at the same time, so cannot give you a before and after of just the Sportlines. I do believe they are worth the money.

You cannot even compair the stock springs to these. They ride a bit rough but the performance increase is worth it. I too cannot get a 3-ton jack under the rear pumpkin without dropping the muffler. For lowered f-bods you can use a 2-ton jack on the pumkin or just jack it from the sides on the sub frame connectors (another reason for them ). I too use the stock isolators by the way.

 

Just roll up on a couple of 2x4's to give a little extra clearence to get the jack under.

 

My experience lines up with Shifty's... Love the sportlines but I do have to use a smaller jack under the SFCs to get it high enough to get a big jack under the front end. I bought brand new isolators when i did the install several years ago.

Anyone ever use the Energy Suspension isolator. http://www.jegs.com/cgi-bin/ncommerc...77&prmenbr=361

It doesn't look as tall as the GM replacement. But I don't trust their pictures.

 

I picked up a low profile jack from Sears that seems to work fine. Its low enough for me to reach the subframes to lift it. I had to special order it and it cost more than the ones they always have on sale but for the ease of use it is worth it.

 

FYI. Here is a picture I found of the original stock 3rd gen rear isolator, next to the new GM replacement. The replacement is considerably taller.

 

awesome responses guys, lots of help. Any price on those isolators? About $5 a piece? I saw that picture comparison thread but didn't make the connection



I can't wait- that stance looks great Adam
