I think you'll like the Eibach kit. I know I do! I got the Stage 1 kit that does the 1 inch lift in the rear and 2.75 in the front. Plus I got the JBA uppers with the updated boot and the ride is AWESOME. The wife and I took it camping/exploring in the forest the very next day after everything was installed and I immediately noticed a huge improvement over stock. We load ~ 600 lbs of gear and things we use for camping and I didnt notice any sag.
I have the Eibach Pro truck lift and cannot be happier with this purchase. In terms of looks of your vehicle, the upgrade in suspension, or the overall increase in performance on/off road, i have no complaints whatsoever. I was originally looking at the 5100s as well but decided the extra money spent on the Eibach kit would be worth it in the long run.
I can't speak for springs in either case. I ran 5100s on stock springs with a previous 4Runner and a Tundra. Liked them quite a bit. I have Eibach Pro Truck shocks on my current 4Runner with stock springs and love them. The dampening seems to be just a little bit more compliant, less abrupt.
You guys all got me super excited ! All these pictures and words are making me excited !!!!! Can’t wait.. the lift will go in in about 2 weeks !! Will post pics once done !!
I have eibach springs and the 5100's in mine and I'm very happy with it. I probably would have gone full eibach had I done it all at once looking back. However I was also in the aftermarket parts business for 20 years with Eibach as one of our vendors and they have always seemed to have on again off again deals with shock manufacturers. I kind of suspect Bilstein actually makes their shocks. They may be different in the valving but if history repeats they may not always be available either.
I would definitely suggest upper control arms too. I run the JBA's on mine and I really like them. I actually just changed out the front lower control arm bushings with Whiteline Urethane and that made an enormous difference in tightening up the front end. It was a HUGE pain to do though. Now I'm looking into options for rear arm upgrades to match.
