Take a ~4100 lb Wrangler and add four 160 lb adults. That's a 15.6% increased static load on the suspension. Small change in ride and performance.
Take a ~2300 lb Fiat 500 and add the same four 160 lb adults. Now you have a 27.8% increased static suspension load. Almost twice the static load and a very noticeable degradation in performance.
Curb weight is a huge reason why heavier vehicles ride and handle so much better when loaded with people/gear compared to lightweight vehicles. If a lightweight vehicle were to compensate, the ride would get stiffer and miserable when there's only the driver aboard.

I've studied some physics. I was just a little unsure of how the logic applied in this case. There are certainly physics at work but weight, or more appropriately mass, is not necessarily a bad thing in terms of facilitating a smooth or comfortable ride. In all likeliness it is a good thing. Not so much for wheeling, but mass lends itself to inertia which would tend to reduce the influence of shock and vibration.

I don't don't know about the lightweight thing. Def dealing with aftermarket coils/shocks. They seem to do better and rated for weight.

The RE front springs for your JK are rated at 185 lbs/in. ...
I have Rubicon Express 4.5" springs (164 lbs/in.) on my Cherokee. I also have Rancho RS9000 shocks with the setting on "1" and it rides a hell of a lot better than my JKU10A. It really absorbes road imperfections, speed bumps, etc. -- but keep in mind I'm running RE Superflex arms with an additional 3/4" rubber isolator on top of the OEM 1/2" rubber isolator. This 5.25" combo works very well around city streets and on the highway.

Good luck whatever you do ...

|jrussblues||The factory shocks and springs are awful. Swap your spacer lift out for a nice coil spring lift with shocks and your wife will be much happier with the ride quality. It is important that you choose the right lift as different brands provide a different quality of ride.|

A really good ride under all conditions requires low unsprung weight. It is a physics thing, and there is no way around it.
Sure soft shocks, low air pressure, low load range tires, taller tire sidewalls, soft springs, etc will help, but all else equal the ride can be much better with less unsprung weight.
This means lighter tires and/or wheels. This may the easiest way to achieve the greatest improvement.

Too much air pressure for sure can cause issues.
|07-02-2013 07:25 PM|
But, bottom line I think it can be made comfortable if you try. That was the main point I was trying to make. Just has to find the right combination to make his wife happy. Unless he really doesn't want her in his jeep!
|07-02-2013 07:04 PM|
Most people seem to like the more controlled stiffer ride with good shocks

And what model is your JKU ?
|07-02-2013 06:21 PM|
Figured since no women have chimed in, I would.
When we went and test drove a stock rubicon at the dealership I HATED it!!! It was the worst feeling thing ever. I wanted to tell Mike not to buy a jeep, but I knew that's the only thing he wanted.
When we picked up his JKU, the ride was COMPLETELY different than the rubicon. I couldn't believe how different it was. I fell in love! So much so that now I want one of my own!
Rode it stock for about a week and changed to 33" tires. No noticeable ride difference. Still comfortable. Then added a 2.5" teraflex lift and the rancho 9100 shocks. It still rides like a dream, except when the idiots overinflate the tires when they rotate them, or when he forgets to adjust the shocks back after wheeling. But within the first five miles you know it's time to change them back, and its easy enough to do.
I swore when I got my odyssey exl that I would never want anything else, unless it was a touring model. But now that I've seen how comfortably a jeep can ride and been able to wheel in the sugar sand, I can't wait to get one of myself. I love being able to see over the other cars and the steel bumpers make me feel safer. We live in West Palm Beach and have snowbirds here half the year and we need some extra protection!
I hope you can get your jeep issue worked out so that your wife falls in love with it as much as you. But then you'd better be ready to buy her one of her own! It's addicting!

Shocks do help, especially our adjustable ones, the RS9000XL.
Aren't happy with them, return them for a refund in the first 90 days...

A monotube will have a firmer ride btw.

My mind is actually boggling at this... When I test drove my JK, I was amazed at how well a coil sprung Jeep could ride, and at least 4 people (not all enthusiasts) have commented about it being way more comfortable and smooth than expected.
Take her for a 10 minute ride in a leaf sprung Jeep and she'll never complain again.
|07-02-2013 12:28 PM|
Would it be easier just replacing the wife?
|07-02-2013 12:11 PM|
|JeepCourtney3700||Trade it in for a Mazda? Otherwise, adjustable shocks. The rancho 9000 series are really, really nice.|

Well for the lift its 2.25 in front and 1.5 in rear because the front end is much more lower in my jeep.
I will try 28 psi and see if there is any changes about the wife I will park the jk for a week and use my old yj to let her know what is the stiff jeep like
|07-02-2013 11:04 AM|
|DirtyTeddy||Nothing will make a noticeable difference she can tell, try shocks and springs. Convinced her a 3.5" lift will do it and maybe the placebo effect will come into play|

Were any modifications made to the suspension? Were the springs changed out or are they stock? What are the last two numbers (the last two will be letters but see what the #s are). They should be 14/15 or so and 54/55/56 at the back- one of those combos or close. I am asking because I changed my springs and went up in weight and it drove like crap instantly after....too harsh and uncontrolled when compared to my stock setup, which was 2-3 numbers lower (was a stock JK at the time).
Also, check your tires. What rating are they- P-metric, C, D? 35 is too high for a light JK to begin with. I run 26-28 on my C-rated 35 MTRs. When I was stock with 32" KMs, I started at 37 and then 35 and it was so bouncy and hard. I talked to the lead Jeep tech and he laughed about the 37 psi recommendation. Said that may even mess up the tire by wearing the middle and affect handling. As I suspected, Chrysler does that to raise the MPG rating by 1-2 MPG. That raises their average and helps them with the newer fuel economy (CAFE) federal requirements. He ran 28/30 and I also ran around 30. Instantly better!
Check all this and let us know. Adjusting your tires will make a pretty big difference right off the bat. Also, what shocks do you have- the stock black Wrangler shocks?

OK.. ill bite and be the one...
Its a Jeep... not a caravan.
