Keep in mind the 2015 RX is an old generation of the RX, where as the 2015 Highlander is an almost brand new generation of the Highlander.

 

I know it's a 9 month old thread, but it's a slow day today.

So anyway... generally speaking:

No Highlander in US = '99-'00 RX300
'01-'03 Highlander = '01-'03 RX300
'04-'07 Highlander = '04-'09 RX330/350
'08-'13 Highlander = '10-'15 RX350
'14-up Highlander = '16-up RX350


From what I've noticed, it looks like the Lexus design language translates across 2 generations. So, the '99-'03 RX300 is similar to the '04-'09 RX330/350. Whereas the L-Finesse design in the '10-'15 RX350 is similar to the '16-up RX350.

 

One other thing the standard premium stereo in the RX absolutely blows away the JBL stereo in the Highlander. Beyond that anyone who says there is no comparison between the RX and the Highlander should really test drive a Highlander Limited. Another thing, if your leasing, I think you will find the monthly payments on the Lexus to be about the same, due to incentives, even though the MSRP is easily 10,000 higher on the Lexus.

 

So if I’m understanding this thread correctly I have individual shocks in the rear suspension of my 2010 RX 350? I’m trying to figure out how to lift my RX but the spacer plugs on offer are a bit short for what I want to do. If I wanted to do a 2-3 inch lift could I just put longer struts in the front and longer shocks and springs in the back?

 

I thought there were no lift kits for the RX350. It is not that type of vehicle. Note that you cannot just throw random longer struts, shocks and springs on it without regard to vehicle weight, spring rates etc as they would probably make your vehicle undrivable with terrible handling. They have to be designed for the vehicle.

Then I found this https://risingtuning.com/lift-kits/product-898

and this https://northwoodsperformance.com/pr...350-2010-2015/

Although neither lifts it as much as you want, which I think is too much for the wheelbase and track, and will result in poor handling and instability. You don't want to be like an old Jeep and rollover on an exit ramp.

Which sort of rendered moot my original opinion below:

There are some for the 2014-2019 Highlander but I do not know if they would work with the RX although they have very similar suspensions. You would have to ask the manufacturers such as https://www.readylift.com/2-0-sst-li...hlander-1.html

See this thread regarding the 3rd gen Highlander which has about the same suspension front and rear although spring rates and shock valving and maybe length are probably a bit different as it weighs more.
Farther into the linked thread are some other ways to attempt to raise your vehicle, although I would not recommend them. Go buy a 4Runner if you want to lift it.

great , would you be familiar with differences between the Japanese and the Canadian versions ? Is it build quality or duty ?

 

I have no idea. Basically I was talking about making sure you get the correct part that will fit your vehicle.
Most aftermarket parts companies do not differentiate between the Canada built and Japan built versions of the RX.
Just get the ones listed for your year and model vehicle.

 

I wait new ver of MDX.

 

Are the rear shocks on a 2015 fsport interchangeable with a 08-13 Highlander?

Part numbers are similar but slightly off. Don’t know if that is a Toyota/Lexus thing.

 

No as those Highlander years had a strut rear suspension and the 10-15 RX has a shock rear suspension.
Read the thread linked below as the Bilstein shocks and struts are far superior in handling and ride to any OEM Lexus or Toyota shock or strut. You want the Bilstein B6 which is equal to the F-Sport version.
However they are officially listed for the Highlander models described below because Bilstein never tested them on the RX. Many members have used them on their RXs.

The front struts are officially for the 2nd gen Highlander 2007-2012 as it shares the 3rd gen RX front suspension. However it has a different rear suspension with struts instead of shocks.

The Bilstein Highlander rear shocks are listed for the 3rd gen Highlander 2013-2018 as it adopted the 3rd gen RX rear suspension. Note that the 3rd gen Highlander has a slightly different front suspension from the RX so its front struts don't fit!

 

thanks! Using this and the link you provided I was able to find the info needed.
