Leveling 22 Platinum with AVS/Air

My bad - load leveling - not AVS.

 

My bad - load leveling not AvS.

 

Just wanted to provide an update on my setup with rear air suspension and AVS. When my '22 was new, there wasn't an option to increase the rear height to go with a front leveling kit, other than modifying or replacing the rear air sensor brackets (which is what I did when it was brand new). Essentially that increased the rear air pressure to raise the back of the truck to the desired height needed to go with the front leveling kit. It worked okay but I knew it had to be a little bit harsher in the rear with the extra air in the bags, even though I thought it rode fine (other than Comfort mode which was a little weird with that setup). I also always had in the back of my mind the concern of possibly over-extending my rear AVS shocks over a big bump and while I never had an issue or damage from that, I'd hate to have to pay that bill.

So a couple months ago I finally installed the ReadyLIFT spacer kit on the rear. This spaces the air bags off the axles and also provides extensions for the shocks, bump stops, and brake lines. That, along with provided replacement sensor brackets, puts the air back to the pressure as was originally designed by Toyota as well as significantly reducing the potential for shock damage. Note that the kit comes with front leveling spacers too so you get a complete kit but I already had those installed.

While the ride was fine as I originally had it, I must say the ReadyLIFT kit was well worth the time and money. I now use Comfort suspension mode as my standard and the truck rides like an absolute dream, while still automatically adjusting for all my work tool and gear load, plus the boat when being towed. The other modes (Normal, Sport, and Sport+) are great too and I use them when appropriate/desired.

So if you have the use for and are lucky enough to have the rear air/AVS and want to level the truck, spend the extra and do it the right way instead of just using sensor adapter brackets. You won't be disappointed.

Now we just need Toyota to build more of these (6.5', hybrid, w/ rear air/AVS) ultimate 1/2 ton towing and work machines. Nobody on earth has an equivalent. So strange they haven't leveraged this but then again, that seems to be the Toyota way

 

No, those are for coils in the back. The brand readylift has 2 and 3" lifts for rear air.

 

This one?

 

That's the one I have on mine. They have a 3" also. Like the OP I took did a front with rear arms and I didn't like it. This was so much better.

 

Yep. That's the one.

 

That's what I run as well. Low bag psi but added lift

 

What size tires did you get on after the lift. Was looking at either 295/70r18 or 285/75r18.

 

I have Nito Terra Grappler 305/55R20. The front leveling spacer kit is a Rough Country 1.75. There was the slightest rub at full lock when the tires were new but it's gone now.

 

They actually only 33” but wider. So smaller than a 34-34.5

 

I recently purchased 2025 Platinum with rear air and AVS and installed lift, 3" SST Lift Kit With CV Axle - 2022-2025 Toyota Tundra Rear Air 4WD with KO3s 295/60/20 on stock wheels. The ride is great, I do notice a small rake, but I'll leave it that way for now. Still in the first week, have to try towing, some 4x4 and longer drives.

 

I would try the ready lift after my 23 plat with avs leveling rear bag popped towing my airstream. The other lift did not use rear spacers.

Long story short I would never own a factory air bag system for a towing truck again! Bilstein 61’s all the way around with an aftermarket air bag system that is much more reliable and controllable!

 

How large was the airstream?

 

did you have a lift that over extended the bags vs spacing them?

 

Airstreams vary for tongue weight 27-28’ are less than 25’.
That said 25’ is what popped the bag.

 

Had spacers up front but did not need the rear arms to level. OEM arms were on the truck when air bag popped.

 

ouch... that sucks to hear.. was it covered by warranty at least?

 

Yes warranty covered but dealer had truck for over a month while parts were on order. Hmmmm.
With a bag popped you ride on the bump stops then which did damage to airstream grrrr.
Traded truck in for 25 without avs

I will say dealer tried to wiggle out of warranty tho but knowledge and firmness prevailed

 

I have some westcott arms I'd sell. I don't need them anymore.

 

Thanks but no thanks. I do not own this truck anymore. You could try selling them in the for sale section.

 

Bummer sorry to hear about that. I like the bags for towing and hauling. I was nervous originally but got more comfortable. Guess I shouldn’t be!

 

I would be worried but to each is their own!

 

Oof that’s no good. I’ll settle for getting my engine replaced sometime soon.
