2013-2018 Toyota RAV4 (4th Gen) Front Strut Tower Bar

2013+ Toyota RAV4 (XA40 - 4th Gen model) Front Strut Tower Brace

Lexus RX350, Toyota RAV4, and the Japanese market Toyota Harrier share the same strut tower design, and share the same Cusco Strut Tower Bar.
Even modern cars such as the Rav4 and RX350 are not immune to chassis flex and deterioration over time, as all metals flex to an extent.
By using Cusco Tower Bars and Power Braces strategically, comfort can increase with shocks and struts doing more work to isolate you from the road harshness.
The more structurally rigid chassis can provide you with less alignment changes and precision in communication with the road as well.
We've provided the basic installation guide here as well.
