Lexus GX460 OEM KYB electronic shock exact replacement alternative
Background
The GX460 comes with either normal shocks or adjustable electronic shocks (if you have electronic shocks your SUV will have 2 available toggle switches just right of the gear shifter: Height control and Comfort/Normal/Sport; if you have a GX with normal shocks, these are blanked out with flat covers for these 2 spots). The front electronic shocks have adjustable damping based on a motor on the top that spins an internal rod to stiffen or soften the damping. The rear electronic shocks, I believe, are ferromagnetic so they get stiffer or softer based the voltage applied to it. The electronic shocks are significantly more expensive than the standard shocks.
KYB makes the OE genuine Lexus shocks for the GX460 models with the electronic shocks. The genuine Lexus-labeled electronic shocks are quite expensive ($350 for each front and $750 for each rear) and I wanted some high quality alternatives. After a bit of research, I found the exact OEM KYB parts from a trusted parts supplier from Dubai (PartsOuq.com) that I've bought genuine Lexus parts many times before.
I bought the following from Partsouq.com and they arrived within a week for installation. The fit, function, finish, electronic harness and manufacturer are the same as the genuine Lexus shocks except that you don't pay the heavy dealer markup fees. The OEM KYB exact replacement shocks are made to sell in countries that don't have exclusivity agreements with Toyota/Lexus hence why the price is right.
Part numbers listed below [NOTE: only buy these parts if you have electronic shocks in your GX460; if you don't have the factory electronic shocks, you will have to order a different set of parts for around $350 (which will have a different part number set)):
741071 KYB front OEM electronic shocks ($110/each; order 2)
4860960090 genuine front shock mounts for electronic shocks ($35/each; order 2)
741072 KYB rear OEM electronic shocks ($173/each; order 2)
4850560110 genuine rear shock cushion #1 ($7/each; order 2)
4850560120 genuine rear shock cushion #2 ($9/each; order 2)
Install Notes (see attached PDF excerpts)
Rears. Difficulty 1.5/5. Installation for the rears is very simple (upper shock tower bolt and lower shock tower bolt; put in the 2 new cushions during install) and will take you about 1.5 hrs taking your time. You’ll need large vise grips to hold the shock tower so it doesn’t spin when you remove the top bolt. Take note of how far down the threads the top bolt is before you remove it, as you’ll be tightening it down to the same spot.
Fronts. Difficulty 3/5. The front installation is a bit more involved (and very similar to most front coil strut replacements), but you'll need: 1) a rented spring compressor, 2) be very patient to make sure you take off the shock tower actuator motor very carefully so you don't strip the 4mm Allen bolts holding it in place due to tight access (extremely important and probably most tricky bit; I used a 4mm Allen bit with a ¼” crescent to turn the bolt head slowly; also of note, during re-assembly, before you reinstall the new shock/coil assembly, loose fit the actuator head back on the new shock tower and align the actuator center motor bit with the flat spindle inside the top of the new shock arm, so don’t have issues during on car install), and 3) the KDSS sway bar can be tricky to put back in place (you'll need a second set of hands to install and a second jack to lift up up the sway bar to put in place). Of note, for the KDSS sway bar, I skipped factory instruction steps 4 and 6--you don’t need to fully remove the sway bar, you just need to remove the 2 end bolts at each control arm so it can articulate to remove the shock/coil assembly.

Do you think this little 4mm hex would fit in there?

However, these new KYBs gave my GX460 a new car feel--a nice compliant ride that's not harsh and still well within Lexus standards. Without directly comparing to a newer GX460 with good shocks, I can't tell you if the original Lexus valving vs. these KYBs are different.
In the end, I wouldn't hesitate in getting these direct replacement KYBs again--not to mention the significant savings over the much costlier Lexus stamped factory KYBs. I expect these replacements to last another 10 years, although I'm pretty sure this vehicle won't still be in my garage in 2031.

If we compared the worn original shocks that came out of my car vs. the new KYB, yes they will seem firmer. The original shocks were worn out and really didn't dampen that well due to use/age.

Great timing on this thread. I have a leaking front AVS shock at 69k and need to replace them. The Lexus shocks are about $190 on PartSouq while the KYB is $109. It would make sense that these are essentially the same part of it’s known that KYB are an OE supplier.

Even if KYB is OE supplier, they would still be firmer than stock Lexus part. KYB is always on the firm side. I replaced quite a few struts and shocks with KYB for previous cars and that was my experience with them.

thanks for sharing your experience. I think i was just assuming that the lexus shock was the exact same item, just in a different box.

Here is the video that shows the comparison between KYB OEM and KYB shocks. https://www.youtube.com/watch?v=uEViDBQssbM The only difference is an extra washer that may potentially add some firmness. Since installing them I can't say that the truck drives noticeable firmer than before.

Great info. My question would be if anyone uses these for offroad adventures, more like overland, camping, desert, no nasty rock crawling but forest and logging roads etc?
Which setting do you use and did it make any difference?
I like the idea I can keep features the truck came with and add a slight lift with the rear air bags and a front 1.5" max lift.
Then all terrain tires and that's it for now.
Daily driver status, fun on weekends.
I don't intend to lift it 3" and put massive tires. In a few years if I feel like really getting into difficult passes I'd be ready to step up.
If these may be slightly stiffer than stock then is the sport setting even more noticeable?

TheNomad: I usually put in Comfort off-road myself but in 4L this apparently triggers Comfort and RAHC Hi automatically.....according to FSM...
One of those "I need to confirm myself" but always forget to check after being in off-road situations
I'll try to do some checks in next couple weeks to see if that does indeed occur though.

I have researched more into this topic especially with the Prado 150 community forums since these shocks first came out around 2016. I had KYB shocks installed about 3 weeks ago and can confirm that they provide great ride characteristics and new like car feel especially comparing to the original shocks with 100K miles on them. Thank you SeattleGS400 for your original post!!!
