Ride quality after LA suspension

I just installed a RE LA kit - on but 3.5" of lift -- without changing the earlier springs or shocks. My '03 Rubicon drives like a 10-ton truck and will beat you to death, even hitting small bumps on pavement.

We intend to add RE monotube shocks. But, is there anything inherent in adding a LA suspension that would change a relatively tolerable and smooth highway ride to being extremely rough? Is there anything inherent in the geometry of a LA suspension that requires softer shocks or springs?


*************
'03 Rubicon -
3" lift, 1" BL, RE LA upgrade, armored, winch, recovery gear...

... all equipment normally needed for Houston traffic

Sorry but I haven't a clue why it would ride rougher. Maybe you do not have enough lift. I love our LA lifts. They made our ride much better, I would even go so far as to say good or better then the factory. I have been telling everyone that a LA will improve your ride and articulation at the same time, at it did on our two Jeeps.

Also have a '06 Rubi LJ, Auto

Due to control arm angles you usually see a much better ride out of a long arm when you approach 4.5-6" of lift. At this lift height the control arm angle is more closer in relation to a stock setup.

I have never seen a LA lift not improve ride, but I also have never seen one under 4.5" of true lift.

Maybe bumpstops are too long and you're bottoming out on them.

Mine rides as good as it did stock, what kind of shocks and springs do you have?

Superior axles doesn't honor their warranty. Don't buy from them.

the smaller lift than normal LA should not make it rougher, in fact, it would probably make it smoother since the angle of the control arms is really what will change the ride (although choice of bushings in the control arms could translate more vibrations as well, but with the RE kit, that's not an issue)

Mine seems to ride as good or better as it did before I lifted it.

So you did not install new springs or shocks but used the OEM ones you had? Or did I read it wrong? "without changing the earlier springs or shocks". Also not sure if it makes allot of difference but I see a 1" bl and no mml? If adding a 3.5 suspention lift with OEM springs and shocks would that not hold back the lift from it's intended purpose?

The springs were 3.5 to start with and probably have sagged to about 3. The shocks were not known to offer the best ride. Now, however, it is astoundingly bad, like a 10-ton truck and must be bottoming out on the stops, i.e. the springs are too short, or the shocks are terrible -- so we will start with new shocks and shock exstention brackets. I will follow-up in about a week when the new shocks arrive. Oh, there is a 1"mml as well.

Have not done my lift yet still reading and learning! P.s. I do however enjoy your choice of music. Not all the time but when working on something or traveling 15th, 16th, 17th, and 18th also romantic classics... My grandfather turned me onto Mozart, Bach, Beethoven at a young age. I am listening to Antonio Bertali as we speak Chiacona A Violino solo... Reminds me of my Grandfather and some great times.

What kind of bushings are in the control arms? Poly on both ends? One end Johnny Joint? Heim on 1 or both ends? Believe it or not, that can make a huge difference in ride. Most people talk about shocks and springs when discussing ride quality, but I'm telling ya that having CAs with the Currie type JJ (or something similar) can have just as much if not more effect on the ride. I've actually found poly bushings at both ends to provide the worst ride.
