Can anyone confirm if 2025 RX350h that the kick sensor with tow package for $870 comes with heavy-duty radiator, cooling fan, and engine and transmission oil coolers. Or is it just the trailer hitch and wiring.

 

No it doesn't. Those items are no longer an option either. I guess Lexus figured out that they were not necessary with the current engine drive train.

The package includes
- Unique rear apron with cutout for hitch
-Tow hitch
- Rubber tow hitch Cover with Lexus logo
-Kick sensor
-Wiring harness/light plug
-Hitch extension/ball receiver (But not the actual ball)

 

Another way to look at this is they don't skimp on the cooling system and just use the beefier system on all builds.
