The rear however, is a little disappointing. They claim 1" but after adding a 58lb bumper.. which was after removing 22lbs of rear bumper/tow hook/tow hitch/stock muffler.. not only was that 1" gone but I then went down another 1/2"

So I'm completely pleased with the front but will need a spacer added to the rear.

As for ride.. its all the same when it comes to traditional springs.

Interesting, I just chatted with quadratec online last night and they told me the are progressive. Chris, have you come up with a different solution?

chris t I wanted to follow up with my experience with Quadratech and give the good and bad. When I placed my order, I ordered the wrong rear shocks. I figured it out when I was posting the part numbers above. When I noticed, I called them and they were happy to change the part number and to change the order. My fault, and they were great with the speed that they changed it. What no one told me was that they charged me another $221 for the new shocks. I let it go for a day and then contacted them. I was told that it would take 24 hours to come off. I don't know about you guys, but I don't always have an extra $221 sitting in my play account, but this time I did. It's been 2 days now and I don't have the money back in my account. Everyone has been great, But I was surprised that they charged me in the first place when the first order had not shipped prior to the change. I will do business with them again, and just wanted to post this as an FYI for historical purposes so that others don't get surprised.

You need to take measurements from mid wheel to the fender. This takes tire height out of the equation.

HK_Runner I tried stiffer JKU springs- absolutely hated the ride. You did the right thing.
05-08-2013 08:36 PM
itssbs I can tell you... the eibach springs are slightly thicker than stock, stiffer and are an excellent ride. I added a warn m8000s winch and lost .5" inches of droop. tried the Rancho 3/4 spacers and did not like the soft ride. These springs lifted the front 1.5" with winch and made my JKR perfectly level to offset the additional weight and is a perfect ride. IMO, my Jeep should have handled this way from the factory. Very impressed! I considered the #18 springs, but, for the money $109 @QUADRATECH, took a shot at the eibachs. Glad I did!!
05-08-2013 04:08 PM
HK_Runner Good choice on springs and shocks. I wonder how these springs compare to the RK, TF, AEV springs in spring rate/stiffness.
05-08-2013 01:51 PM
Rancho Subscribed.... I like reviews.
05-08-2013 01:49 PM
jadmt subscribed. I have been on the fence about getting some eibach springs as well. I have used them in the past on motorcycle shocks with good results

chris t MacCTD, We have a 4 door with the tow package on it. All was fine until we added the rock hard full width bumper, and the winch. We're looking at rear bumpers and a roof rack, plus the couple of hundred pounds we add when we load up the kids, dogs, and camping gear. I did give thought to the jeep parts upgrade, but decided on the progressive springs instead.

MacCTD If your JK is a 2 door why not just put on a set of 18 and 59 springs with Rubicon shocks, pretty inexpensive way to firm up the suspension on a 2 door and gain the close to 2 inches in the front and 1 inch in the rear.
05-08-2013 11:57 AM
chris t That looks really nice, just what we're looking for.

chris t G-Mike,
The part numbers are RS999326 front and RS999327 rear. They are 0-2" lift. Since this is only a 1" lift overall, it should be perfect.

Wheels082,
The Teraflex are a linear spring, and the Eibach's are supposed to be a progressive spring. The idea behind the progressive spring is that as it compresses more, the spring gets more "stiff". So as you load it with more weight, the spring should ride the same. The issue is whether the Eibach's are truly progressive or not. It's hard to tell based on the pictures that ITSSBS posted.

It looks like the upgrade will happen over Memorial Day weekend. I'll post the before and after pics.
05-08-2013 11:27 AM
wheels082 What is different/how do these compare the the Teraflex leveling kit springs?
05-08-2013 10:12 AM
G-Mike What part number Rancho's did you get? I was looking at this configuration myself.
05-08-2013 07:02 AM
mopar guy Let us know your thoughts this is the setup I want go with so I'll be watching this post.

Eibach's been in the game for a long time, both are made in the US, both are progressive. I couldn't find any real useful data on the Eibach's, so I decided to try them. I figure I'll be the guinea pig for these and give some opinions on them. If they suck, then I'll send them back and order the Synergy. I have used Eibach on my sports cars before and really liked them. I will let you know how they work.

I decided on the 9000's because of the adjustability. I have used the 5150's on my FJ, and loved them. I will put them on my Tundra as well soon. I know how the 5100s are. Rancho has a 90 day try it or return it policy, so I'm going to give them a try. Again, I will let you know what our thoughts are.

I sincerely appreciate your comments on your posts, and the fact that this board is great about not slamming people for asking questions that have been asked before. Thanks!

Chris, My experience with Eibach springs is on a 2003 Cadillac Escalade that I purchased new in 2003. The springs lowered my rear by 2 inches and I now have 75,000 miles on it. Over this period of time there has been no sagging in the springs and the SUV corners very well at high speeds in the mountains. I have carried some real heavy loads in the back of my Escalade and never any spring issues!
I understand two different type vehicles and you are lifting and I lowered, but just wanted to share my positive experience with you. They are definitely of high quality, Good Luck!

How are they handling the weight ? Did you take measurements before and after ?

Edit
Hmm progressive ?

Ordered Eibach Springs and Rancho 9000xl

Well, I finally decided on what I was going to order and I ordered the Eibach Lift and Level kit. Progressive springs were important to me since we camp and add a lot of weight to the JK. I didn't want to lift too much since we expedition more than crawl. It essentially came down to Synergy or Eibach's. They both offer a 2" front, 1" rear progressive lift setup.
