Since they are for Highlander, does that mean they will work on RX, as its based on Highlander?

 

Yes, the third gen RX and the 2014 and newer Highlander are built on the same platform and share the same suspension design, engine, transmission, brakes, power steering etc. I put the Bilsteins on the rear of my RX and it was a huge improvement. I had been running the Sport Suspension rear shocks which were used on the 2010-2012 Sport Package and similar to the later F-Sport shocks. The Bilsteins ride much better and handle just as well.

 

Thanks for this update. Good to know that we can now install Bilstein B6 components on all four corners of the third-generation RX350. That is exactly what I plan to do when the factory components begin to show signs of degrading. They are still functioning properly on my wife's 2015 RX350 as it approaches 52,000 miles.

 

just now on the rock auto site...decent pricing

 

I would not put those front assembly's on. They will not ride as good as the oem springs .Just buy the kyb struts and use
your original springs . Pay a shop to switch them over for you . I've done it both ways .

 

has anyone install the highlander bilsteins in the front as well? i plan to replaced my rears with the highlander bilstein but i want to do the fronts as well. im at 75,xxx.

 

I would NOT do the back only, if you want to change them do all 4 also be aware that the valving will be different from Lexus OEM and consequently also the ride.

 

My rear shocks were shot (70k) so the ride was a bit mushy in the back.
Installed just the rear Bilsteins and the ride/handling is great.

 

The front Bilsteins work well. The whole ride is stiffer and handles better.

 

Replaced my rear shocks today with the Bilstein B6. What a difference they made.
My shocks were totally shot. Nothing left in them.
The Bilsteins tightened my ride up and no more floating feeling. Felt much more in control of the vehicle.

Now I'm noticing the front floating around and rough. The struts are next to be changed.
I'm going with the KYB front strut assembly. That's for next week.

 

Why are you deciding not to install Bilstein B6 front struts? Front left is part no. 22-282873. Front right is part no. 22-282880.

Also, what is your current mileage?

 

I suspect he is going with the KYB complete strut & spring assembly which eliminates the need to compress the spring, but is usually of overall lower quality than just replacing the strut and strut mount bearing. I too do not understand why someone would put a sport shock in the rear and a regular strut in the front and have a handling mismatch.

If you do not want to compress the springs yourself you can always take your removed strut assemblies to a local gas station or repair shop and they will compress the springs for you and swap everything over. I know folks who have done it that way and the cost was about for an hour of labor. This is a simple job for a professional as almost every strut is the same procedure.

 

Also using different manufacturers could cause problems with handling due to different valving.

 

Thanks for the info.
Yes, I was using the KYB assemblies because I did not want to compress the springs.
I did not take into account everything that you mentioned.
I'll go with the Bilstein's in the front and have someone else compress them.

Thanks again.

 

Hello,

Does anyone know of a thicker rear sway bar that fits the RX350?
