They may or may not make a difference, everyone perceives their vehicle ride differently and has their own expectations. I don't mind the bounce and do not think it bad and I even installed the sport suspension rear shocks, but I used to have a MINI Cooper S...
Rear shocks are not that expensive, from this link you can see the Monroe's are under $50 each at Rock Auto https://www.rockauto.com/en/catalog/...+absorber,7556
You could probably have your local gas station or any local mechanic install them in less than an hour. I replaced both of mine in my garage in less than an hour but I have been doing my own car repairs for many years.
Not much of an investment to see if you want to keep the vehicle.

Kyb strut plus
Has anyone had any experience with putting on the KYB Strut Plus (complete strut assembly) on your 2010 or newer RX350? I recently purchased them from rockauto, and I'm looking for any info on what to expect and if I go with a different set up and return these. Any information would be helpful! Thanks!

Bilstein B4 series are equivalent in ride and handling (but better) to the original struts and shocks.
Bilstein B6 series are equivalent to the F-Sport shocks and struts for those who want improved handling with a slightly stiffer ride. I have them on my RX and it rides better than the F Sport rear shocks I had before and no worse than the original ones.
However, if you want a better ride than the KYBs get the Bilsteins front struts that are listed for the 2010-2013 Highlander as it has the same front suspension as the 3rd gen. RX350. The B4 model is the same as your OEM. Part numbers 22282675 and 22282668
If you decide to replace the rear shocks with Bilsteins, you want the ones listed for the 2014 Highlander as it has the same rear suspension with shocks as the RX. The 2010-13 Highlander is different in that it has struts in the back.
Part No. Bilstein 19-282862

However if you just want a good ride, get the B4 series. Rock Auto has them as does Shock Warehouse and maybe Tire Rack. Look them up under 2015 Toyota Highlander with the 3.5 engine.
B4: Front Left: 22282835, Front Right: 22282842, Rear: 19282862
B6: Front Left 22282873, Front Right: 22282880, Rear: 24282901

I installed the Bilstein B6 rear shocks on my 2010 AWD RX350 and aside from them being a very tight fit in the upper mount, they fit fine and drive great. I actually found that on the passenger side it was easier to remove the upper shock mount, 3 bolts, then bolt in the shock, then put the upper mount back in. It was very tight and hard to line up. The driver side went right in. I think that was just unique to my car or that shock. Others have had no such complaints.
Bilstein does not list it for the RX350 because they have not tested it for the RX. They developed it for the 2014 and newer Highlander which has the same rear suspension as the 2010 and newer RX and has a bigger market and more buyers who would modify their vehicle with higher performance shocks & struts.
The 2008 - 2013 Highlander has the same front suspension as the 2010 -2015 RX.
The 2014 Highlander was a redesign and they adopted the RX rear suspension which allows more rear cargo room, but it has a different front suspension.

I replaced the factory rear stock shock absorbers with KYBs. The ride actually seemed softer. Maybe because the factory ones were leaking. I had trouble getting the originals off, so I took it to a local repair shop. Hope this helps.
