I am very new to lexus but so far i love it. I have a 2008 RX350 AWD, I want to get a half inch to and inch more of high. If that safe enough on a stock suspension?
I was looking at either strut spacers, or a taller strut. I havent been able to find any coilovers that have the same bolt patterns.
Is it true that the toyota highlander is compatible with the rx? And what years? And are highlander actually taller than the lexus strut?
or would a strut spacer be good enough just for a bigger tire for some light dirt roads?

 

You need 2008-2009 Highlander struts, or 2008-2013 if you want quick struts, the 2001-2007 Highlander struts are the same as the stock RX ones. Quick struts will come with the taller springs

 

O8 or 09 highlander quick struts will bolt right in to the stock mounts?

 

You might not be able to use the 2nd gen Highlander's top strut mounts, you might have to use your stock ones for a proper fit. There is lots of examples of people doing the swap on Toyota Nation on their 1st gen Highlanders.
