Air Suspension Headaches...

Today I made an attempt to level my truck. Long story short, I gave up in frustration and ended up putting the OEM links back in.

Started out great..got all the parts I needed and the assembly went good too. Than when I installed them, my truck didn't like them. The truck looked great being leveled but it road like complete @$$.

Every little bump I hit it was like a trampoline and would bounce along. I expected a little rougher ride but this was almost unbearable. Also, I wasn't able to go into the highest setting as it kept saying "payload too high." I read somewhere that you have to drive it around a little bit to get the suspension use to the different links and I even reset the air suspension a couple times and it didn't help.

I know people have done this before and were able to make it work without any issues. I'm just wondering if anyone can help me out with this. Do you have to drive around for more than a couple miles for everything to work itself out?

Pics below...don't mind the dirty truck.

Too much $$$. I wouldn't get the use out of it. All I want to do is level it out.

Are you having an issue with the air ride system at all? Like any over payload messages? Do you have full use of your air ride adjustability with no error messages?
interested to know as well. I was going to make up a set of links at the "ideal height" and give it a try my self.

So did you make "sweet spot" links or come up with your own measurements?

Made my own links but I'm just trying to work out the kinks. I made them adjustable so if this were to happen I can work around the factory air system. I'm thinking that if I make them a little bit longer, so lower the front end a little bit, it will get close to "the sweet spot" so it will level my truck error code free.
I figured out the trick...just took some playing around to find the "sweet spot." Originally, I made the links 5/8" shorter than OEM links. Even though it got me to level, I believe the air suspension system was trying to pump too much air in the front bags to achieve it. This morning, I made my links the same as OEM length and started adjusting them down from there. Once I hit level, tightened them up and took the truck for a spin. It almost has a factory ride now. It's a little more rigid but not by much. I laid some paint over them...when they dry and I get them installed, I'll post up some pictures and measurements for everyone. My links only ended up having to be a little more than 1/4" shorter to achieve enough lift in the front to level it out with the rear.

Your links are too far out of the PCM's parameter, that's why it's getting nutty & overpressurized.
There is a sweet spot, I've posted the measurements here many times, the links I made are cheap plastic tube with small holes drilled in each end to fit on the ball ends. I've had my truck on these modded links since I picked it up from the dealer in September. Below are the correct measurements for everything to work properly.

Front links: from center to center of each ball stud must be no more than 4 1/8"
Rear links: from center to center of each ball stud must be no more than 3 3/4"

The modded link measurements are in the center. Note* The rear is made longer & the front is made shorter.


This is what's been on my truck since September., costs less than a dollar!

An 1/8" shorter in the front & a 1/4" longer in the rear than OEM is what I've posted in every thread about this mod to make this truck ride stock @ taller height & level. The key is the measurements must be from ball center to ball center.

I saw your measurements numerous times on here but I was only interested in leveling the truck - I didn't want to touch the rear so that's why I didn't use your measurements. Thanks though for your contribution...I'm sure there are a bunch of people that want to get lift all around.

I adjusted them today to a point where I don't get any system failure messages and still achieved a level stance.

I was only interested in leveling my truck as I didn't want to touch the rear. I saw your posts as well. I tried just doing 1/8" shorter in the front and didn't get what I was looking for.
That's because the PCM compensates for the difference up front when it senses the rear has changed as well.
Anyway, glad you got it back into parameter so it stops goin nuts on you.
RR,

What height do you get with your links? I just installed mine for 4" in the front and 3.75" in the rear and that got me Off-Rode height in N mode. Is this where you are at too?

Exactly!:), I just never use off-rode mode anymore.

Awesome, I notice no ride height quality issues so I am going to try and push it another inch. I'm used to cars with track ready suspensions so I imagine I will hit the system limits before I find myself with a harsh enough ride to matter to me. We will see.

I tried that & didn't like the ride, too harsh.

Roomraider - you able to run either r35x12.50x17 or 315x70x17 on stock rims with this mod of your custom link set up? Or do we need to change rims?


Sorry if all of this duplicate info. Here is my list of things I plan on doing the 1st month of ownership
From Dealer - before I pick it up
1. Black MOPAR side Steps
2. Dodge MOPAR cab lights


After I pick It up
1. Link modifications. Looking for RoomRaider help
2. 35x12.50x17 or 315x70x17 tires
3. Flow master outlaw muffler P/N 817633
4. Some brand of Cold Air Induction kit. K&N or AFE or ????
5. Tint front drivers side / passenger side window to match rear doors


More to follow. Always open for suggestions

Can't wait to see your new Rebel, post pics immediately:D we love pics here. The only tire I've tested with this mod is the Toyo R/T 35x12.50x17 which fit like a glove on stock wheels with no rub whatsoever after link mod & new alignment in normal mode. The R/T's are new to market and much better than the A/T imo.
