The 04-06 H/L O/E hitch is nice. It's the same part # as the rx330/350/400H. I have it. In fact, when the H/L was delivered ,the tounge and hitch pin came in a Toyota box stating a "Lexus part#".
The heavy duty radiator, Transmission cooler and trailer Pre-wiring harness(Tow prep Package) is a separate option code from the trailer hitch option code. But the hitch ends up being wired to the prewired harness. The Tow Prep pkg. is factory produced at assembly. The Hitch (toungue included also, but no ball) is Port or even Dealer installed.
To me it looks like it is
black powder coated paint. The aftermarket hitches always rust out and look bad after a couple of years.
The Hitch is really nice stuff. I checked out all other brands before I ordered the H/L. and I took the O/E Hitch. Got the H/L for invoice anyway. I had to get it. Foolish if I hadn't. I had to get all option codes in fact. The price was just too good pass up.
Get the O/E hitch . Yu will thank me. Sits high and flush mounted. The correct way it should be mounted too. This is so easy to install, had I needed to install myself. Simple bolt on. Remember to torque bolts to spec.
Comes with a Toyota labled Reciever Plug. The Hitch is a 2 incher/class 3.
The O/E Hitch clears the exhaust resonator tip perfectly.
Rememeber, if yu don't have the Tow prep pkg., your
gross tow capacity is
lower as stated on a lable on the O/E Toyota hitch.
w/prep-3500lbs.(V6),3000lbs.(4cyl.)
w/o prep-2000lbs.(V6), 1500lbs.(4cyl.)
This is because The tow prep pkg. includes:
larger radiator, transmission cooler, high amp alternator,fan coupler.
