Shocks and Struts

Wondering if anyone has attempted or knows a reason why I could NOT fit a load adjusting shock to the GX460. No one sells a direct part but it does not seem to be a difficult fitment when looking at the rear shock.
For some reason its also kind of hard to find the rear shock from many vendors at all unless your doing a lift.
I do not have the air ride system, just regular old shocks on the rear.
It seems to me there is plenty of space around the stock rear shocks.
I have the boat well positioned on the trailer to try and limit the tongue weight.
When towing it is NOT riding on the bump stops and I have never felt them contact in case anyone was thinking along those lines again just looking for slight ride improvement and don't see a directly listed fitment option.
I do not want to adjust the ride height. I tow a 6000lb boat on a fairly regular basis and wanted to help the squat and keep the front down during towing, and stiffen up the ride when turning.
I had these on an f150 a few years ago and it basically felt like I put a stiffer anti roll bar on the backside.
2015 GX 460
for example this has a very similar range of compression / extension 14 and 22 inches is listed on stock

Just looking for thoughts/experience and Thanks!

The advantage of the Timbren product is that they do not (significantly) change the ride characteristics when you are not towing, but will engage when the tongue load causes the rear-end to compress. Timbren Load Supporting Bump Stops ...

The advantage of the Air Lift product is that you can "air-up" or "air-down" based on your tongue load to the exact amount of rear-end lift required to re-level the vehicle stance. Spring Coil Air Lift Insert ...

Are my shocks blown?
Noticed that my front shocks (2011 gx460 at 82k miles with AVS) are quite moist on the dust cover and part of the spring. Are they blown?

Unless theres another source to that oil stain it certainely does look that way. At that age and mileage its usually a good investment.

Yeah I had a leaking shock like this awhile back. Replaced the shock. Felt good again.

Yes, you need new shocks. Only 82,000 miles with this leakage combined with the cost for AVS Shock replacement is absolutely criminal given the performance improvement over good quality conventional shocks is subtle at best. On a GX470 ... I ditched the AVS shocks when faced with the same and never looked back ... significant improvement in ride and handling for a fraction of AVS shock replacement.

Softer riding shocks for base model
I know there has been a thread on this subject that took on a life of its own but I’ll ask again and hopefully I’m not given engineering classes because my son takes that as a freshman at UMass Amherst. My question is my shocks are nearing its life expectancy(I have 90k) and I’m interested in replacing them with a shock that tends to give a softer supple ride if it actually exists. At last check I can get all 4 corners of KYB Excel-G for around $400 on Rockauto.com and factory for about $50 more on a Lexus discount site. I have heard Monroe makes a soft shock but doesn’t last as long as does Gabriel. I know it won’t be night and day by just changing shocks but I want to know what SHOCK will address the undesired firmness the best. I know my go to ACRAD mentioned possibly an aftermarket air shock dampened to its softest setting. Thanks for your time.

IMO, if you're going aftermarket, get Bilstein shocks, I think they are one of the best shocks for ride comfort and performance. They are more expensive but do it once and do it right. Don't get Monroe, they will be gone within a year and don't get KYB or you may loose your teeth. I ran both of these in other cars and won't get them again if there are other choices available.
Not just shocks, you also need to make sure the springs are rated for your load too. Some people get too stiff of springs thinking of overloading them in the future to settle them down. This results in harsh ride/bouncy

I'll be direct ... Monroe and Gabriel shocks are absolute garbage ... inferior in every way, and will be completely shot in less than 30,000 miles. If I may suggest ... rather than focusing on "soft and supple", focus on "controlled damping" which is where Bilstein rules ... comfortable and controlled with a perfect amount of road feel. As you know, the GX460 is a truck based platform ... so dumbing down the shocks will never achieve a Lexus RX ride ... and is unsafe from an overall vehicle dynamics standpoint.
I agree ... the KYB shocks feel like they do a marginal job balancing performance with comfort ... not a bad job, but higher end alternatives do much better at achieving this balance.

4600's if they fit ... some say are identically valved as the 5100's, but some say the 5100's are firmer, but I have not found that to be the case ... unless the 5100's are on the higher lift end of adjustment. The 4600 are for non-lift applications.

A video explaining the differences
"4600 is the most stock-like, 5100 is for some improved handling, larger wheels & tires over factory, and some better offroad capability and durability."
