Does 450h use the exact same shocks as RX350?
Anyone know for sure?
I recently had a RX350 loaner and a NX loaner and both times when I got back into my RXh I immediately realized that I liked the RXh better. Don't get me wrong, the RX350 rode quite well but the "h" had smoother shifting and handled road bumps better, probably due to the extra mass, no so much due to shocks.
Just get my point across better, here is what i'm referring to: The shock absorbers reduce and slow down (damps) the vibrations from the springs which must be beefier on the H due to the heavier weight. As such, to make the ride quality "equal" with the rest of the RX line up, a sane and half intelligent engineer would specify a higher damping rate for the H than that of the pedestrian model RXs.
What I want to know is: Is it verified that H models and regular RXs have different shocks? Or did Lexus specify the same part thinking that 400 lbs doesn't really make a difference. (In the late 80's when GM had buick, olds, caddies, and a couple of other brands it used the same old part everywhere thinking no one would notice.)

The ride quality is noticeably harsher than the previous RX 400h. More bouncy, more transfer of road conditions.
Can this be improved with different shocks/struts?
Or tires?
Thanks,

Can't say whether that means the shocks are the same or not. For example, Canadian version has a different part number from the Japanese.
Considering that RX450h rides softer than its 350 counterpart, it is hard to say whether 350 shocks/springs would make any positive difference.
And as far as aftermarket support, there's virtually none.
