I had the dealer try to install a set of 2010 f40 sway bars on my base 2008 ls460.

bars hit components in the suspension. Could not use. Had to remove. Reinstall front bar.

‘Rear requires subframe removal. $$$$

Anyone run into this issue?

 

Did you buy the right drive type? AWD vs RWD?

 

were f40’s available in both?

 

Yes, and the bar is VERY different

 

Here’s the front bar they sold me. 48811-50230

 

That part number only fits RWD.

 

I applaud your effort to improve handling, and by ordering parts meant for other model years! Quite certain I would not have gambled on these particular parts though because the 6 or 7 parts sites I checked did not list fitment for 2008s or for mine which is a 2007. I believe the first refresh years were 10-12, so I guess it's a bit of a surprise the front sway bar did not fit considering the control arms are interchangeable. I wonder if the slight diameter increase is the reason, or were you able to compare the two side by side, as far as the shape/design?

I recall you mentioning purchasing the larger bars and was hoping it would work out: https://www.clublexus.com/forums/ls-...l#post11235529

As far as the rear bar, a few of us had a discussion about it and how much work it would take just to access to switch out the bushings. https://www.clublexus.com/forums/ls-...ng-change.html

 

my 08 is a base RWD. Would an air suspension 2010 car have different bars than a spring car. Thanks for the help.

we’re all f40 sports air suspension? Different arms?

almost looked like a 2010 sport f40 models frame mounting points were spaced away from the 2008 frame. Shims do not show in fiche. Maybe a frame mod to space away the bar? Anyone have a f40 that can look in that area

 

I forgot to add that the part number is for 2009-12 RWD.

Mine's a 2007 L so I'm not familiar first hand with the 10-12's "sport tuned air suspension" that Lexus called it. However, from what I recall, it was only available on RWD models, and I would suspect the air struts are similar but have a different dampening rate/oil for more taut handling at the expense of a stiffer ride. The newer, refreshed lower rearward control arms (the #2 arm for RWD models, 4862050131, 4864050131) is listed on parts sites for 2013-17 models; however, a good number of us here have installed them w/o any issues, including myself. Furthermore, the parts sites have only 2 numbers (4881050020, 4881050030) for the stabilizer bar links that seem to cover all model and sub-model years from 2007-17.

Although the bar ends should link/line up in the same position, this info leads me to believe the sports suspension stabilizer (sway) bar may not be a direct bolt-on for our non-sports/F models due to one or a combination of the following: collars/mounts position, increased diameter, design/shape. If one was set on using the sport sway bar, with some customizing and ingenuity, drilling and tapping to create new mounting locations could be a possibility. Obviously, we cannot rely on parts sites to show accurate depictions of the thousands of parts. Below is my sway bar from MAR 2021 when I installed all new front control arms and sway bar end links and poly bushings. (vs parts sites)
