Rear air suspension

I’m new new here and have 2022 Platinum. I searched a little for this answer and cannot seem to get a simple answer to this question. Can you raise the rear suspension to the high position and have it stay there all the time? Regardless of the speed, payload… top position no matter what

 

Nope

 

no, but you can adjust the rear linkage to permanently raise the back end. Just have to loosen a nut, move the lever and tighten back up.

 

That’s the simple answer I didn’t want but thanks. I just think it looks better in the high position

 

So if I loosen that nut and change the position, when it says N on the dash it will really be in the high position? It’s really that easy?

 

yessir

 

Nice…

 

So even though it feels like it's already been answered, it's just a bit confusing cause it seems like it defeats the purpose. But let's say you throw 2,000 pounds in the back, overloading it to the point where it'll definitely sag, it'll only raise it below 15 MPH or so? Or will it at least combat the sag?

 

If you set it to H while loaded, itll go back to N once above 15 or 18mph, whatever it is. Im not sure what the max psi is set within the system, but it will try to keep it at N height upto its max psi allowed.

 

So maybe a dumb question. If you move the linkage thus putt the N setting higher, do you still ha e the ability to raise it from there with the switch? Or ha e you effectively taken away the ability for it to go any higher?

 

Being able to raise air suspension is kinda dumb when its only on the rear axle. The lexus GX has adjustable rear air and its virtually useless for actually improving its offroad capabilities since the front bumper and skids are the low point anyways. It probably makes the front approach angle even worse by tilting the front down.

I think Westcott Designs makes a lift for the rear air suspension. I would do that before you adjust the linkage. By overfilling the bags you may hurt the ride and stress them a bit more.

 

the rear air isnt designed for off road use...heck, its not even available on TRD models. Its strictly intended for towing purposes.

Westcott actually does the same thing as adjusting the rear link...they just provide a link that is key'd different than oem. Sounds like you dont know what youre talking about here. Have you done any research on the subject?

 

They say they provide billet lift pucks for the rear so, you know, that's what I assumed they did. Even with billet pucks, I would think they would have to still adjust the arms to compensate for the increased height, the bags just wouldnt be overinflated as they would be at their stock height. Lose the attitude.

Whether its intended for offroad or not, its a less than an ideal way to do it. Its a cheap and roundabout way for the reasons I stated above.

 

No attitude, just making sure readers get accurate information from informed sources. You suggested the Westcott kit but now you're saying its a cheap/roundabout way...again with the conflicting information. Your post was full of inaccuracies and didn't address the question at all...allow me.

The bags will have an additional 6psi in them (per Westcott) with the Westcott rear arm...not overfilling anything by any stretch.
The Westcott link will clock the arm differently to achieve (To a greater degree) what you can accomplish by simply adjusting the OEM arm. Pucks are not used on trucks with rear air.
If this is the case, then adjusting the OEM arm would likely add less than the 6psi with the Westcott unit...again, no overinflating
The only advantage to the Westcott kit is that they provide a 1/4" spacer for the rear shocks. This means you do not run out of shock down travel if it is stretched beyond oem spec.

@area52 yes. Adjusting the arm essentially puts the N ride height a bit higher. This means that the H ride height is proportionately higher as well. You don't lose the ability to raise it via the paddle switch. H height doesn't matter since it resets to N once you go over 15 or 18mph.

 

thank you eddiefromcali....I adjusted the OEM arm and it worked great. It was a cheap and easy fix to accomplish what I was looking for

 

yes you can still raise after adjusting the normal to be higher

 

Thanks gman & eddie

 

Can you tell me how this is done?

 

It's been asked and answered before in this thread

 

It does seem like my ride is pretty poor after raising up the Neutral height. It avoids bottoming out but does seem to degrade the overall ride. Any idea what the max psi of these bags is?

 

Ready through the new Tundra manual, it does mention that lifting the rear air suspension to the high setting can be used for, "bumpy roads," at 18mph or less... I haven't tried this yet, but I wonder if the ride quality improves on "bumpy roads."

Any way to add front air suspension and loop it into the same dash switch as the rear, and then just lift and lower the whole truck for off roading?

 

So I read a Toyota suspension control adjustment (Toyota document) and it says that the sides cannot be adjusted independently of the other as they are not controlled independently. While this makes sense to me because I have tried getting them even and have gone as far as maxing the driver and minimizing the passenger side arm, and the passenger is still higher than the driver, I still can't understand the purpose of having two arms then.

Has anyone tried this with different results or can explain why they have two arms then?

 

I have the same issue right now, my passenger side sits higher by a 1/4in. I measured from the center of the wheel to the bottom of the fender above, the fuel tank was at 1/3.

The front is dead even, which makes the difference in the back stand out more . Have you figured it out?

 

I adjusted mine. So I loosened the nut and slid both arms up which gained me about 1.5”. (37.5” ground to bottom of wheel well on stock 20’s. every now and then this truck sits 1/2” lower on drivers side. No idea why. I did wonder if it’s fuel weight as the tank is on drivers side

My ride quality improved.

 

I took it in a few times and specifically showed them pictures and told them they need to check the tech stream settings. Supposedly they did. I think 1/4" is normal and is tolerable. Mine was more like 1/2" most times.

Yeas the front is dead. I recommend a 2" level on the front or a 2" level with a 1" rear lift. I have one for sale.

 

The dealership said it could be the fuel tank but that's not it. It didn't change when it was empty or full. Also, it is self adjusting so it would account for that.

 

I measured mine on a daily basis for about a week when I would get home, for what ever reason it seems to change daily by 1/2 to 3/4" ......always driver side. I moved those arms about 6 times trying to compensate for it, finally said F it. Also as I understand it the self adjusting is from the " N " position which is set by the arms we can adjust. So if " N " is a 1/2" lower on one , it still will be after it self adjusts up or down due to load .

 

you guys are really caring about a 1/4" variance? I haven't measured mine but it looks even to me

 

No not 1/4". But 1/2" yes as I can see the difference at that height.

 

you must have a super flat spot to measure from then with that small of a variance?
