GX ride

Agreed. My OE Bridgestones are no longer as harsh as during the first year of ownership. Tires in general can make a significant difference. My GX still rides more comfortably on winter tires.
Hang on, isn't this why the lube tech was hooking up a vacuum pump to my tires?
This has to be one of the biggest shams of the industry. Sad that folks will fork over $100+ for this "addon" - not calling out the OP.

So marketers represented as a consumer benefit ... a complete joke ... and Costco has Nitrogen available ... but not 100% Nitrogen from "scuba tanks" ... it's from a CO2 converter that's not even close to providing 100% Nitrogen.

It rides firmer than the last generation GX that I owned. Every Lexus has gone firmer.
It being "body of frame" though is not the problem, ride in something like a Tahoe/Denali that has a similar design. WAY smoother ride.
It's still a serene ride (way better than a 4Runner for example) but I would argue Lexus made a mistake trying to chase companies like BMW to be "sporty". People want smooth luxury with a Lexus.

Too much unsprung weight. The 18in wheels are like 32lbs each. The tires are like 39lbs each. I plan on switching to the TRD Pros and lighter Primacy LTX tires. Saves around 15lbs per corner and a thicker sidewall to boot.

For those drawing comparisons to the Tahoe and Yukon, remember that the GM SUVs all use independent rear suspension vs the GX which is solid rear axle, and many of them also have air suspension. The only GX with air suspension, for better or worse, is the Luxury model.
One will ride smoother, the other will go for 200k miles with no maintenance aside from new shocks if you so desire.

I have to stop you there though, my last GX had major suspension replacement beyond the air springs at around 130k miles. Struts/shocks (front and rear) ball joints, tie rods, sway links etc. And the air springs failed, but it was honestly not that big of a deal.
It's only the most recent Tahoe/Yukon (2021+) that have an independent rear suspension. No question Lexus makes a better product than GM, but they could have had their cake and eat it too by simply dialing back the suspension firmness, even with a conventional suspension system. Even the steel spring Tahoe's simply have a smoother ride than this generation GX.
Lexus got it in their head that their cars are "boring" so they decided to try and make everything more "European" in terms of handling. And then had overkill on some of the styling.
I don't think many people are going to think the GX has a "harsh" ride, but it was a step down from the last generation.

To be clear ... the Lexus GX460 (Luxury) does not have "Air Suspension" ... it simply has air bags (as springs) in the rear for load leveling ... providing spring rate adjustability to compensate for rear end sag. The front suspension is ... and has always used springs on all trim levels.

How the hell does that happen? I'm at almost 176k and all my steering and suspension components are flawless. Are you the original owner? If not, the previous owner drove the **** out of it.

Unless it's just smooth highway miles, the concept of not needing anything suspension related addressed before 200k miles just doesn't seem realistic imo. You often times dont realize how bad it's gotten, like when you replace things like the sway links or tie rods, the car feels so much sharper.

A lot of that is pretty normal wear and tear in my opinion. It's not like all of these parts were destroyed and made the car dangerous, but you'd be amazed how sloppy things can get and you don't even realize it.

Yes, that makes sense. Yet, my wife's Jeep Grand Cherokee seems to be absorbing them much better. I'll see how I t feels after 5k miles with the tires broken in a bit more.

^^ Agree ... specifically the OEM Shocks that get progressively sloppy from 85,000 miles. Change them out and immediately question why you lived with the original ones for so long. Have done Upper and Lower Control Arms in the 100,000 mile range ... the rubber bushings do deteriorate and get sloppy based on environmental conditions as much as from wear-and-tear.
Any suggestions for aftermarket shocks for good ride ?

we have a 2022 gx 460 premium plus. We recently replaced the stock 19" wheels and tires with 17" TRD pro wheels + Michelin Defender LTX tires. Ride is noticeably smoother, less jittery when going over road imperfections. Overall, we are happy with the results.
