I've been wanting to upgrade the shock absorbers on my 2007 Lexus RX 350 to Bilstein Shocks. Does anyone know if their Bilstein B6 Series shocks are compatible with my RX 350?

 

There are no dedicated struts for the 2nd gen RX, however they made Bilstein B6 struts for the 2010-2013 2nd gen Toyota Highlander. These can be installed on your RX350, but you will gain an inch or so of height due to the 2nd gen Highlander having taller struts than a 2001-2007 1st gen Highlander (where the 2nd gen RX suspension architecture is from). Be aware that all of these will bolt on no problem, except for the front passenger side strut. This is due to the Highlander spring being wound counter-clockwise on that particular side for that reason on that specific model - thanks Toyota. This is a problem us 1st gen Highlanders have run into and it means you will need 2010-2013 Highlander front springs for this to work. I would recommend the FWD model ones to match the spring rate of the 2nd gen RX, the 2nd gen Highlander is a heavier car.

If you want to complete the package, I would do sway bars and lowering springs as well. I got H&R springs for an RX300, they lowered the center of gravity while still providing a comfortable ride and helped stiffen up the car. The rear springs are progressive instead of linear like stock. You would need Toyota Venza lowering springs to match the 2nd gen Highlander struts, but we'd need to find out if the Venza has that counter-clockwise spring at the front right or not. As for sway bars, the front can be directly taken from a 3rd gen RX350. 26mm vs 23mm without any added understeer. There are also aftermarket solutions for the rear. The front requires 2013-2018 Lexus ES350 front sway bar end links to work, but other than that it is a direct bolt on. These modifications apart from the Bilsteins (I chose KYB) made the car handle VERY WELL, especially since it is a near 4000 lb SUV. Corners a lot better than most sedans I have driven.
