Lexus GX460 2020 – Comfort-Oriented Suspension Advice

[Kyrylo25]

Hi all,
I have a 2020 Lexus GX460 (60k miles) on 32.5” Falken Wildpeak tires — each wheel added ~20–22 lbs over stock. Since the switch, the ride feels harsher, especially when hitting potholes. It seems like the shocks can’t keep up with rebound, and the ride feels jittery.

My goals:

1. Softer, more compliant street ride (no lift).Sometimes doing overland.
2. Better shock absorption over dips and bumps with extra unsprung weight

I’m considering:

• KYB SR Battlez kit
• Eibach Pro-Truck Stage 2
• Eibach Pro-Truck Sport
• I would also be happy if someone could find me comfortable springs that don't require replacing the struts.

Looking for feedback from anyone who’s tried these setups — especially in terms of comfort and whether they improved the issues I mentioned. Open to combining springs + shocks if needed, but want to keep stock height.
Appreciate any advice!

Not able to provide any help on the suspension front, but why not spend what would effectively be the same amount of money on a lighter wheel/tire setup? The Falkens are notoriously heavy, and the harsher ride is probably from the higher load rating vs stock.

Or just chuck some new suspension on it and enjoy it.

Is your tire E rated? If so, its probably your tires. Need SL rated 285/70R17 if you want max comfort.
Suspension will help a bit but would not take care the real issue. Even using C load rated would make it a lot more comfortable..

what kind of new suspension?

 

[Roody]

what kind of new suspension?

Depends on budget, end goal, desired lift, and whether the vehicle has rear air bags, etc

 

[r2m]

One thing you did not mention is, what is your rim size? A 17" wheel with a tall sidewall tire will provide a better ride, especially when aired down.
That's assuming the tire is not a LT (light truck) rated tire.

I got r17 Trd

The goal - more smooth street driving . Lift is not important for me. Car without airbags.

check the tire load rating. That's going to make the biggest difference. My prediction is that making suspension changes with make it even rougher.

For best ride you want stock springs and stock ride height. Bilsteins have digressive damping that will be rougher on small bumps than OE. Looking at shockwarehouse the stock ride shocks left are Monroe and KYBs. KYB makes good stuff. The OE shocks are KYB. That's what I would get.

From the weight it sounds like your tires are heavier duty than needed.

What's that got to do with it? I don't put any extra weight on my car at all, the tires are soft, the question is that the original struts can't handle that weight.

Which KYB's would you recommend and why ?will they handle the extra 20 lbs of weight of each wheel ?

With all due respect, I disagree.
if one carefully does their due diligence in researching suspension, tires AND what their end game is for mods, e.g.: full overlanding, and rock crawling = very heavy; trails, camping, fire roads, = medium weight; suspension and tires just to keep it looking like a soccer Mom or you're taking your kids to violin lessons = light/stock weight. Match that all together, their ride should be better than stock.
If you do all that, most everyone on this forum has found the ride to be as good and mostly consider the ride to be better than stock suspension.
Go to my build thread here: R²M 2013 GX 460 Overland Build and look at my build and suspension. The ride is absolutely wonderful! My wife and I did a trip from our home in So. Cal. to Maine for a lobster dinner and did it in nine days. Some days traveling over 1,000 miles in one day! We couldn't have more comfortable other than being a little sore after so many hours sitting. Other than that, the ride quality was better than stock.

After 7 years, I just swapped out my Icon suspension and UCA's for all OME components. Only have had it on a couple days, so the suspension still has to settle in. But so far great!

As @r2m said, load rating makes a huge difference. Running an E load tire on the street is like wearing a steel toe boot for running; it'll get the job done, it's just not optimized for the job.

Check the load rating of those Falkens. I bet they're E. They might feel soft to the touch, but they don't conform easily.

Improving suspension compliance will help but ultimately wheels and tires are unsprung weight. The impacts and jolts you feel from hitting potholes, broken sections of pavement, road joints, etc won't be significantly helped by putting on better suspension when what's on there is already good. Lessening the weight at each corner and making the tire compound better suited to road use will help the most here.

That sounds cool but I just have a falcon wldpc at/4 , I also load the car with absolutely no weight other than my 230 feet, can you give me any major advice on what type of suspension I should install based on the goals I wrote in the title of my post

The tires is 115T

That's a speed rating, not a load rating. What is the tire size? (Not the 32.5" mentioned, the actual size stamped on the sidewall)

What tire pressure are you running?

Whenever my truck rides like s*** its because some tech put 40 psi at each corner. I run my 34s at 30 psi and can still get decent mileage.

I have 95 lbs a corner with e load range and its still smooth with bumps. Just some NVH from the mud tires.

I commute over some crappy roads, so tire pressure is critical.

 

[Banandalorian]

Before you buy new shocks, have you checked your tire pressure?

I agree with tire pressure. But it's kind of a double sided sword. On one side you'll a wee bit better MPG with a higher tire pressure, but with that, you'll feel every bump and if tire pressure is too high, poor tire wear. A lower tire pressure will give a better ride and the sacrifice of a little lower MPG and if the pressure is too low, poor tire wear.
I just purchased OME suspension from Mudify and the owner, Eddie at Modify.com and he was very helpful in dialing in my needs with how I've built my rig.
