9000xls what am I feeling for?

So I installed the 9000xls and initially left them at the 5 and 5 setting. Tried 4 and 4 and now 3 and 3. I don't really notice much of a difference. Can someone explain what I am to be looking for as far as ride?
I can still feel slight bumps in the road and when going slow over speed bumps my JK still rocks back and fourth as the stock setup did. Maybe I am expecting too much, I don't know.

Ride quality is subjective. Only you can answer what you're looking for. It's a Wrangler not a Lexus. Try cranking them up and see what you think. Tire pressure also plays a roll. Too much pressure will make for a harsh ride and wear your tires unevenly. Don't forget to rotate them every 5k or so.

If you don't like them return them if you can. They might not be the right shock for you...

No. I was trying to help out. A lot of guys run them on 5. Lower setting are softer. More body roll. Higher settings are stiffer with less body roll. That's my understanding.

You are going to feel bumps no matter what shock you buy. There are scores of threads on shocks especially Rancho. Do a search. You'll have a better understanding. If you're unhappy and it's been less than 90 days you can get a refund and start over. Put your old shocks back on and spend more time reading and thinking about exactly what you want to achieve.

What's your tire psi and load range ?

There's a pretty decent difference between .. Say 5/5 and 3/3

2-3 is a little soft. I preferred 5 or even 6/5

Experiment.

I installed these last week and started at 3/3. Felt too soft, so went to 4/4. The back felt a little jumpy, so went to 4/3 and that seems real good so far.

At 3 for the front it felt a little like an old Delta 88.

I have them. You should definitely notice a difference between 5, 4 and 3. But some are more in tune than others with that kind of thing.

Are you talking highway driving, or around town? On road or offroad? That might be the issue.

Running stock Rubicon wheels & tires, I found that 4 was stiffer than I wanted, 3 wasn't bad, but I like 2 because I like to feel the suspension working. Our roads around here are pretty rough.

... and I think alot of folks run these 3 front, 4 rear if I'm not mistaken. But I don't know that there is a "wrong" setting - personal preference. I might try 1 and 9 one day, just for fun.

Kj, just had the tires rotated two days ago. They set them at 40 psi. right front is actually39. Load range C Bf Km's. I had them at 36 prior to taking them in. That might be the problem. I appreciate all your guys input as far as what you run and your trials. Never really thought of mixing the setting from front to rear but it makes sense due to the weight issues.

Oh this is mainly in town with a few brief 15 minute drives on the freeway.

Let me back track on the 40 psi thing. I went next door to our power generation shop and grabbed a Milton Chicago slide tire pressure gauge and it showed my tires at 36 psi. The Slime made in China needle gauge shows 40 psi. I think it's safe to say the made in China needle gauge might be off.

I have 3 Minton gauges and they all read differently so I would not put 100% faith in those.

Regardless of tire pressure you should still be able to feel the difference between the shock settings. The entire range has to be within a safe and usable range otherwise it could cause unstable or highly uncomfortable ride. If you can image a complete range of damping where 0 is no shocks and 100 is solid shocks then the 9000XL adjustment range is probably something like 40-70.

To get a feel for the difference set first to 9 drive it including some bumps or potholes that only affect 1 tire and then set it to 1 and do the same. Keep in mind these are adjustable shocks with presets not fully tunable shocks that provide enough rope to cause problems for yourself.

If you can't get a soft enough ride with the shocks with your normal tire pressure then consider lowering the air pressure in small increments.

Awesome, will give it a go.

Turns out my slime dial gauge with bleeder is pretty accurate compared to the Miltons.

Same experience with gauges. I had one read 5psi too high.

One more thing for someone pondering this adjustability... it wasn't until I went over a speed bump that I realized that the front was harsher than the rear. That's when I settled on a 3 front, 4 rear type of setting. Could be something to do with the angle of "impact" in relation to the control arms as well, but yeah - try the speed bump test to help dial them in.

Nature of the beast. Front transfers shock all the way down the chassis.

Had them at 7-6 today.. think its safe to say they are working. Felt like wagon wheels compared to the 3-3. Got them at 6-5 and that might be the sweet spot. I did try the speed bump test and your right I could tell.

Thanks for all your inputs.

Sweet man .. Also keep in mind. Temp will stiffen shocks. I didn't look where your located. Once it warms up you should notice more of a change between the settings. Freakin April and temp hasn't broke 60 yet

Very cool! Glad you "felt" them.

Does anyone have a preferred setting for beach/sand with the Rancho's? I have the RS9000XL's and am curious if those settings will make a difference when i hit the beach this weekend.

I think that unless you will be prerunning or constantly flexing and trailing on the beach, shock stiffness level will not improve anything in sand. The most improvement will come from airing down the tires. Sand is soft, and will yield, but sometimes its bumpy, or flat. Too stiff and bumpy sand will have you shaking, too soft and you will be like an old pimped ride up and down. You may want something in the 4 or 5 numbers.

Beach sand by nature is smooth so unless you plan on flying off of sand dunes the shocks tuning will not be a major factor. If you run for an extended period on dunes then fade can become an issue.

Running at medium to higher speeds on sandy desert trails is a different story.
