How to Level a Jeep with Quadra-Lift Air Suspension 

This is the first time I have read every. single. comment. on a youtube video. Excellent work! Hope to try this mod next spring but will probably order the ready made parts.

There is a factory rake because of payload requirements. If you fit 4 grown adults or a small trailer it will squat the rear end. Even with the automatic level adjustment of the air ride, it still needs to be higher in the rear than the front otherwise the vehicle will become unstable at certain speeds. Not only is your wheel alignment based on this but also your axles. I don't think it's dangerous to do this mod and it absolutely looks better but the mod doesn't take into account all the engineering thoughts. Ideally if they needed a rake in the suspension, I think they could have designed the fender openings to be a little lower. In the SRT models, the fender flares do cover more so at minimum SRT thought about it a little.

this brother's ocd is serious. i have a wk2 and i totally get it, i dont like the gap either but i wouldnt go thru all of this. maybe if i was more handy. well done man i wish i was as handy to do this. GOOD VID

Hola. Muy bueno el video. Podrías indicar en qué medida dejaste los brazos finalmente por favor. Muchas gracias

I'm impressed you took this on. But you didn't actually show removing or reinstalling these tubes (these are tubes, right?), or which tools were used. It is encouraging that you didn't have to remove the wheels. And, btw, for headlight adjustment, which direction do you turn it to raise it up and how much difference does a half turn make?

Nice video, subscriped.

has anyone had any success with adding the spacers to the struts with these links? like they do for the ram's with quadra lift? Makes it a much more smooth ride i hear.

Hey Tony very informative video. I'm a Chrysler Tech and thinking of leveling/lifting my 2014 Grand Cherokee Summit. I know when I currently put it in Offroad I/II the ride gets much stiffer. I assume that once you made your adjustment to the ride height link you have a stiffer ride as well? Thinking of adding the Rough Country Ride Height Leveling Kit.

Hi Tony, well done really nice and informative video. I was wondering if you've had any problems with the QL after this mod? If I understood you currently, the Jeep is now in Off-road 1 mode all the time? Please correct me if I'm wrong here. Did you tuned the rear end as well? Thanks, Sagi.

Awesome video Tony. Is your Jeep in the video at ride height? Just wondering when you have it at the lowest point (exit) does still sit pretty low.

A cheaper route for the all thread is going to Home Depot and buying machine screws M5-.8 x 80mm. That gives you 3.13” of thread and you only need 2.91”. They are $2 for a pack of two. They are also stainless steel.

Tony, great video and explanation. It appears you kept the OEM 20" wheels and simply replaced the standard tire with a more aggressive A/T type tire. If that's correct, can you share with us what size tire those are and if you encountered any rubbing particularly on the front tires against the inner wheel well liners or suspension components. I've been wanting to do just what you've done but up until now was not aware of how easy it is to do. Thank you.

Tony Great video. My desire is to LOWER my 2011 GC Overland. I want to set the standard ride height at the lower setting but not have the traction control turned off, which happens if you dial in the lowered SPORT setting. So if I fabricate some of my own adjustable links am I correct that, I need to lengthen the front links to lower the front and shorten the rear links to lower the rear. If this is correct do you lave any idea what , say 2mm in length does to the actual ride height, IE. 2mm longer link in front lowers Ride.Hht. 1/2 in? And finally, do you measure the ride height on level ground across centerline of wheel to underside of wheel well OR do you measure from center of wheel to underside of wheel well just curious? I'm sorry for so many questions but like you I'm a little OCD myself!

Cool video's. Do your front struts make allot of noise over bumps like speed bumps and other low speed vertical movements?

Hi, great video and thank you for sharing. Can you confirm the final length you ended up with overall. Thx

Hey tony. Great video. I love watched it a few times and the first time I understood everything. Then I confused myself and am now wondering how a shorter rod raises the vehicle and a longer rod lowers it? Can you explain? Thank you!

Which way do I turn headlight screw to lower the beam of headlight..... I'm blinding everyone on the road 😅......

Great video! I'm here in Oklahoma as well as have a WK2 Overland Summit with QL also. How is yours holding up overnight? Are you losing air when it sits hours? I am in the front only, but it raises back up just fine when started. I have the links, both the leveling ones and also some raising ones, or maybe its the other way around (leveling = raising, lowering = lower than stock). Where are you located, NE, Central, SW, etc? I'm NE.

Any issues with tire wear, wheel alignment, etc? Was reading a few posts from the forum and this issue was brought up a couple times. Curious if you had the wheels re-aligned after installing the different air links. Thanks

Tony Great video, I am junior Romero from Dominican Republic. I have a jeep Grand Cherokee over land 2011, and it has the following problem : sometimes it goes up alone, and does not go down by the down button, and although the vehicle goes at a speed higher than 100 km / h it does not give the down signal. Now the vehicle has remained in the lowest position, and does not rise, Now the vehicle has stayed in the lowest position, and it does not go up, if I press the up button says; nor does it do anything, but if I press the down button, it tells me that it is in the lowest position. in previous times they have changed the shock absorbers, the compressor, and the valve set, and today again I have the same problem with the suspension. Where can I get the electric, and / or electronic manual of this vehicle?

Hey what’s up man! So i have a Jeep Grand Cherokee high altitude 2018 with the air suspension and i looked on the adjustablelink website and i only found for the 2017 and below!

I am preparing to do this same fix but question is - will it not affect or damage air bags when ride on off-road 2 option, air bags will be stretch in that option probably above maximum working capacity ????

Great video!!! If you answer some questions. I also have grand Cherokee and I’m trying to do the same thing to mine. What is the height of your wheel fender flare after the adjustment and what airbag position? In what air bag position were you adjusting the links on, was it on the entry/exit or Level 1? Thanks for doing this video!

Questions both raised modes were not affected? And question two how short could you possibly go on the rod to lift it higher without over airing the bags?

Could you just shorten the stockers to 4.5" as long as both are done evenly? Thanks for your time

How do you instal the safety pins on the joint, especially the top one it is imposible to do it?

Hi Man, I have a 2017 WK2 Trailhawk Hemi "QL of course", and I really want to correct the rake / leveling, do you recommend any good quality ready-made rods ? do I need to do anything else beside shorter rods ? Thanks a lot :)

Anyone that wants to just buy it made already for cheap. Message Shane Brief on Facebook.

I think you can set the desired height with the right scanner to access car air suspension control module

what happends when you take it to the dealer and have the module replaced and you have to do a relearn on the height sensors? if the technicians do not know you did this they may not be able to set the ride height properly again and it will/may not be able to set the hight properly. this could cause a lot of frustration.

My 2012 overland is displaying a message that the air suspension is cooling down and than the height won't change knowing that sometimes everything goes well and desired height is set, any idea what to do?

Great video! I am in Tulsa- what part of OK are you in?

What were the exact measurements for those front links ?

What about the off-road modes? Do each of them still work correctly and function fully?

what is the ball size of the 2 joints ....i seen that the all thread is 5mm... where did you purchase them from

Do I just buy 1 threaded rod that's 1m long? Then cut to size?

What size and brand is that tire

So stupid question. I have all the parts. How do I get the male end out of the female end when first purchased from the store.Thanks in advance!

what kind of tires are those? And where can I get them?

Will this work on a 2wd Limted with air suspension?

In Canada those elbow joints are called ball joints. Just to help those looking for that part.
