@Urlik You could well be correct. I am positive I was told and or read that the $870 tow package included heavy duty radiator, and other upgraded parts. A parts search is the best way to determine. When I looked at detailed parts lists, I had a hard time finding 2024 model year lists. Everyone had 2023 parts diagrams, and perhaps the 2023 and 2024 parts are identical. What I know I got: factory or port installed hitch, rear mounted plug, relocation of the kick sensor, a receiver (but oddly no ball), and a branded cover to stick in the receiver hole when not using the hitch. In the Lexus cost/price world, I expect that is probably what you get for the $870 cost. Having said all of that, many Lexus dealers say what Longo Lexus does - and it sure looks like a canned Lexus-provided description: https://www.longolexus.com/blogs/307...wing-capacity/. And different dealers use the exact same language to detail what the tow package includes - which sure looks like Lexus-provided language and not dealer happy-talk. I am a bit doubtful the consumer-facing parts list is up-to-date, given the fact that an entire model year (2024) is missing from many of the Lexus websites I looked at.
So I am still uncertain.

I doubt anything changed parts wise from 2023 to 2024.

Agree. From my poking around I don’t have a great sense about 2023 parts inventory being fully accurate either. Seems like there are endless threads here with people trying to find simple things like winter mat part numbers.

Looks like my original thread was deleted and my question merged into this obsolete thread as post #13. I say obsolete because there is no longer a "$160.00 Tow Package" in 2024. It is now an "$870.00 Kick sensor with Tow Package". That's the reason I started a new thread. Too bad, because now we are not likely to get a verifiable answer to the question of what the $870.00 3500lb tow package actually includes because the title of this thread is obsolete and will not attract the appropriate attention. Please restore my original thread.

I think you are correct. When I was deciding on what options I wanted on my 23 RX (in a perfect world), I did not see an option for a Tow Prep Package. This was in June/July of 23. I spent a LOT of time going over this information and really don't think that I missed it somehow.
I tow with my other vehicles and would like to at some point with my Lexus (around 1,000#'s). Hopefully we can get to the bottom of this eventually.
But quite frankly, I find it hard to believe that towing this amount of weight would cause any harm to the powertrain with the existing engine and transmission coolers.

I'm very satisfied with my two RXs, but can't imagine you'd get much from Lexus for $160...maybe they've become more generous

My understanding is that the $160 "Towing prep package" includes only the pre-wiring. You need to buy the actual hitch and actual wiring harness on top of that. Look at the "BUILD" section of the Lexus website.

The $160 tow prep package no longer exists on web site as an option. Most likely an error since it only applies to previous model. 2022 and prior.

You just need a hitch and a wiring harness. Aftermarket or the Lexus tow hitch package.

This is not entirely clear. I posted this in the question about 2 inch trailer hitch.

The dealer spent a lot of time figuring this out. I believe I am correct in that the 160 dollar items is the "converter" cable. This is required to activate the brake lights. it is not the cable that has the 4 pin connector. That is another cable. Look at page 18 of the link to see part numbers. If you want a non Lexus hitch you could get by with the 160 dollar cable and everything else could be non Lexus. There are some people who posted that the factory kick sensor still worked but I had the dealer install the shorter cable and sensor
