Installed the Eibachs today. Full review to come, but during the test drive they are a significant improvement over the ranchos. Honestly on my truck I never felt like the Ranchos were lacking in the handling department, but they totally sucked when it came to absorbing a bump... frost heaves, speed bumps, etc... it was horrendous. The thing was like a bucking bronco. One frost heave near my house in particular I couldn't take at over 5 mph. During the test drive I hit the same heave at 5, 10, and 20mph and it was hardly even noticible. So, a definite improvement in that regard.
The ride is slightly stiffer (and I mean slightly) but not bad at all.
For what its worth, I installed the Eibachs on the 3rd setting and I have ~1" of rake. The 3rd setting did actually give me a little more lift than I wanted, but I will see if the suspension settles at all. I actually think the Eibachs give a little more lift than the Bilsteins. I saw ~1.75" of lift in the front end on the 3rd setting. So I would expect just over 2" for the highest setting.
All in all, they seem like a nice set. I will give it some time, get an alignment, and report back.
Note: in the picture below the truck is on a slight incline which makes it look like its a little nose high (just look at the wheel gaps).
