Darren from Truxx must not have communicated the latest news to his staff. I have a text response from him from April 21 acknowledging that he is working on the strut extension. If I were you, I would hold off (I'm assuming you have the self levelling shocks).

Here is the response from this morning when i asked about darren and the extension:


“We have tried many times to replicate the error but we cannot...so this has asked us to have dealers do it and some can, some cannot replicate the issue ( we are not at the shop so we have to trust what they tell us) we are not sure what is going on but it seems there is an install issue on some trucks as others work fine.

Darren has a shock, is going to try and make a bracket but the shock is speed and load sensitive...if you install it wrong it won't matter what shock bracket you use, it will still fall back to a low setting.

The shock has been around forever...GM used it on a lot of Tahoes and Suburbans and we had no issues with it there, Saab, Peugeot, Nissan, Subaru lots of companies have tried it over time.

I know Darren has not been able to replicate the issue if he installs the rear kit correctly, he is working on building a shock extension...but in his words "the correct fix is a real shock, the added load and unsprung weight of larger tires, bigger rims, anything that changes the unsprung weight can also affect the sensitivity in the shock and a shock bracket may not be the answer to fixing a load and speed problem"...

Read this so you understand unsprung weight...

Unsprung mass - Wikipedia

So, everything matters when you are setting up suspension, it is not simply one thing all the time...

We will make a shock bracket for the truck, some time in the next while although time frames are impossible in these pandemic situations...

Go read about unsprung mass, then read the instructions again on the shock description...it all might make more sense :-}”

I'm sorry you guys are having issues. I've had my Truxxx lift kit installed for months and thousands of miles with no issues. I have a 2020 SX-P with self leveling shocks. Tires are Good Year Dura Trac 265/60 r18. I measure 35" to top of fender front and back.

Hello, I just joined the Telluride Forum today as mine will be at my dealer on 05-22-2021.
I would also like to be updated on this Truxxx 2" Lift when it is resolved.
Thank you for the information.

I just got my kit in today. Planning on doing the install myself seeing that looks pretty straightforward after reading the instructions and watching videos on TY. But does anyone know where I can find torque specs for all the components needing to be unbolted? I was thinking of just starting at a lower torque setting and moving up from there till I get the numbers but this may not give me exact just ballpark numbers.

The 2” lift was a Huge upgrade for my Telluride. And the 265’s with Black Rhinos look too good..

What are your wheels specs?

Just wondering if anymore has been heard about this extension truxxx was looking at possibly making; and/or any additional info on this possible problem? Want to pull the trigger in the lift, but just nervous to do on a brand new vehicle some people have had trouble with. Whats the consensus? Problem mostly just install error?

I went to a local very well-known four-wheel-drive shop and they’re telling me that All the lifts they’ve done with vehicles with the automatic leveling system they got longer sensors from the leveling system company and at this time they don’t make a sensor extension for the telluride but they’re saying that is the only correct way to do it adding extensions to struts and stuff is not a good idea just thought I’d pass this information along

Yeah, i dont know much so i have no clue, but the reason i am holding off so far. Especially of truxxx is looking at fabricating an extension. Leads me to believe me even they think one might be needed. But i know a few have said they have had no problems, yet. Worried long term and that perm extension of the shocks

Not sure if they are talking about the same thing. Automatic leveling systems on air suspensions have a level and air compressor and they adjust the height automatically based on what the leveling ride height sensor arm says by adding or removing air pressure to the air suspension. The extension they are talking about is a longer arm to the leveling sensor. This is not what the Telluride self leveling shocks do. The self leveling shocks have fluid in the shocks/strut and they activate their leveling with motion. As the suspension bounces it mechanically pumps it up to try to get closer to normal height while driving. When you stop it sags back down and the shocks rest. There are no sensors. Adding extensions to the Mando self leveling shocks/struts the same height as the lift might be the answer but there are no sensor arms to extend. I could be wrong, but this is how I think it works.

Received my Telluride, loving it so far. I installed the K&N CAI system, love the sound at WOT. The Borla exhaust just arrived today and is an easy bolt on. Used the same rims but swapped the tires to a set of 245/60r20 Toyo Open Country AT3. Also installed the Truxxx lift yesterday, love the stance and everything about the ride so far.

That said, there is definitely an issue with the Truxxx lift and the self-leveling suspension. I appreciate the fact that Truxxx has been the first and only manufacturer to provide us with a lift option, but they are definitely lacking when it comes to the Nivomat system. Nivomat components are designed to work at a certain opperating height in conjunction with the spring, as they are not coil overs. By adding approximately 1 3/4 inches to the spring height, nothing is done to address the new height of the Nivomat shock. I am going to have to figure out a way to fabricate a shock extender to address the additional height that is now required. Hopefully I can come up with something this week but it may take longer. The washers they suggest could help are not the answer, nor is the simple 'disconnect the battery' line sufficient. I did this step, but it still ignores the fact that the Nivomat is now almost 2 inches longer than it should be during normal ride height.

Borla:

nice!

Here when i got the notification of a response to this thread, i was hoping it was an update to the thread topic….nope. Lol

Hey Guys... not sure if this thread is closed but from what I understand... if you do NOT disconnect the battery the self leveling computer will not be able to understand what's going on with the new ride height.??? That's what I read in their very detailed instructions. They also said some installers don't install the sway bar links that are included and that could cause some issues.

Hasnt been any real update in it. Im confused by it all and while i want to do it, dont want to take the chance of messing up a brand new vehicle. So probably going to just forget it for a while. Maybe some other options will cone out. In going to re-read this thread and some others just to try to understand it all better. Was hoping there would have been more updates and/or responses from the truxxx lead about the possible new brackets or something.

I did the install myself. Did disconnect the battery and installed the links. Been driving like that for about 2k miles and the car still sitting leveled. The only problem I just found when I did my oil change is there grease at the front passenger side. I think it's coming from the drive arm (forgot what the proper name is). Has anyone notice this?

Now that I have my telluride, I can verify some things. You do not have to disconnect power because there are no height sensors on the vehicle, nor do they electronically controlled struts(front) or shocks(rear). Nivomat design is self contained, and self regulated. They are not “smart”. Without a shock extension and a lift, they cannot push up because it’s out of the range. On non-load usage with a lift, they could appear to sag or be level, but with people, could easily appear low on either side AND in the rear(depending on weight). Load depending, with the lift, you could actually have sag and not trigger the nivomat’s internal sensors to correct the issue.
They need to make a lower shock extension at the minimum, or get a spring and shock kit going. One possible thing to add, is that vehicles with nivomats have softer springs. So that is not helping the situation either.
