Very rugged hitch. The installation folks said that it fit perfectly as they sometimes have difficult installations with hybrid vehicles. No issues at all with this one. Etrailer has been great and we will be purchasing a hitch bike rack from them!

Straightforward installation on 2022 Lexus RX 450h. I’m an average-sized guy, able to do this safely without having to raise the vehicle.
I needed to use an extension (~30” pipe) to exert the 79 lb-ft of torque called for. Maybe my new torque wrench is miscalibrated or maybe I’m just a lot weaker than I thought.
The most helpful video instructions for my 2022 Lexus RX450h were from U-Haul.
Shipping was fast and flawless from E-Trailer.



by:

Fit almost perfectly (cut away a tiny amount of foam insulation). Installed easily by propping it up on a few paint cans and books then used a socket wrench with 6" extension to tighten bolts.

That’s so great, 100% match

The holes in the hitch could have been a little bit wider. Other than that it was an easy fit.

Easy to order. Quick to ship. Quick to arrive. It was a fairly easy installation. Took about 75 minutes to install. Perfect hitch to carry our bikes. Thank you for great customer service!



by:

Very happy with my etrailer purchase. The dealership wanted to charge $1,700.00 to install my hitch. Etrailer saved me significantly without any hassles. I was able to purchase and have my mechanic install a hitch for 1/3 of the dealership cost.



by:
2020 LexusRX 350

Installed in about 15 minutes. Two bolts out, two plastic bolt hole covers out, loose-fitted the hitch in place with two bolts to mark plastic under bumper, dropped one side of the hitch, cut the plastic with a box cutter, bolted on the hitch. Done...! Dealership wanted $1k. Mine's a 2020 RX350 base FWD.



by:
2017 LexusRX 350

Lexus wanted $640 plus installation for a trailer hitch. Etrailer had the exact same hitch for about $200 and it came with FREE SHIPPING! I got the hitch in just a few days from ordering and installed it myself in about 10 minutes. Never used this company before, but I will definitely recommend them.

  • Will Curt Trailer Hitch Receiver C73DR Work W/ Lift Gate Sensor On 2021 Lexus RX 350
    The Curt Trailer Hitch Receiver # C73DR you were looking at is a confirmed fit for your 2021 Lexus RX 350 and will fit with your rear lift gate sensor though it will likely change the location your foot must be to activate the sensor. You will need to place your foot to the left or right of the receiver for the sensor to detect your foot. If you are planning on towing with your RX 350 you will also need a vehicle wiring harness # C56217. I included videos of the products mentioned for...

  • Bike Rack Recommendation for 2020 Lexus RX 350
    Hey Max, you would want to install a trailer hitch on your 2020 Lexus RX 350 like the part # C73DR so that you can install a hitch mounted bike rack like the Hollywood Racks Trail Rider part # HR200Z to carry your bike. There are no trunk mounted bike racks that are a fit for your vehicle.

  • Trailer Hitch Recommendation for 2018 Lexus RX450H
    The etrailer Class III hitch part # e49KR is confirmed as a fit for your 2018 Lexus RX 450H so it would work well for you. For trailer wiring you'd then want the part # 118255 which is a confirmed fit as well. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip,...

  • Will a Trailer Hitch Fit and Affect Liftgate Sensor on a 2022 Lexus RX 350
    We do have a hitch that will fit your 2022 Lexus RX 350 with the Curt # C73DR. This hitch will still allow you to use your liftgate sensor, but you will need to kick to either side of the receiver as opposed to just swiping your foot under the bumper. If you were planning on using this for a bike rack, then I recommend checking out the RockyMounts WestSlope # RKY10222 which has a unique U-Shape that makes loading and unloading bikes much easier than most other platform racks.

  • Replacement Hardware Kit for a Curt Hitch
    Hey Edward. The Curt Hitch item # C73DR is the same hitch as the pn 13515. It does indeed fit the 2022 Lexus RX 450h. When you transfer the item # C73DR hitch over to your new Lexus you'll need the Replacement Hardware Kit for Trailer Hitches item # RHK. The hitch bolts are only designed to be torqued down once. This kit provides the correct length and grade of bolts that you'll need to reinstall your hitch. You will want to go to the item # RHK product page and type in 13515 in the...

  • Will The Curt C73DR Hitch Fit A 2022 Lexus RX 350 F Sport
    The Curt Hitch # C73DR will not fit on your 2022 Lexus RX 350 F Sport, it only fits the non-sport version. There is not a hitch for the sport version of your RX 350, but could help you fit a roof rack if that would help.

  • Hitch And Wiring Harness Recommendation For My 2022 Lexus RX 350

  • Bumper Panel Modification Required for Trailer Hitch Receiver On a 2021 Lexus RX 350
    When installing the Curt Trailer Hitch Receiver # C73DR on your 2021 Lexus RX 350 while there is no drilling required for installation, underbody panel(s) and/or fascia must be temporarily loosened or removed. Trimming a portion of the lower fascia panel may be needed to reattach panel or fascia. This could be something like a 3" x 3" hole that can be cut with a cut off tool or by using a small hack saw. I also recommend installing the Tekonsha T-One Vehicle Wiring Harness # 118255 before...

  • Curt Trailer Hitch Fitment on a 2022 Lexus RX 350
    Yes, the Curt Trailer Hitch Receiver # C73DR will fit your 2022 Lexus RX 350 as long as it isn't the F Sport model. If that's what you have then you'll need the Draw-Tite Hitch # 75540 instead. If you're planning on using this for a bike rack I recommend checking out the RockyMounts BackStage # RKY10002 which is a platform, wheel-mount style rack with a built-in swinging arm so you can gain unrestricted access to the rear cargo area of your vehicle without removing the bikes or the rack.

  • Will Trailer Hitch Installed on 2021 Lexus RX350 Affect Operation of Hands-Free Liftgate
    As long as your 2021 Lexus RX350 isn't the F-Sport model, the Curt Class III hitch, part # C73DR is a confirmed fit. The Curt # C13272 hitch you'd looked at isn't a confirmed fit. We haven't received any feedback stating that installing the Curt # C73DR hitch has prevented the hands-free liftgate feature on the Lexus RX350 from working, but it will typically block the sensors from reading input right at the center of the vehicle.

  • Recommended 2 Inch Hitch for a 2021 Lexus RX 450h
    I have a solution for you but the Curt Trailer Hitch Receiver item # 13445 does not fit the 2021 Lexus RX 450h. The only hitch available for the 2021 RX 450h is the Curt Hitch Receiver item # C73DR. This hitch is custom fit and bolts directly to your RX 450h with included hardware. It does not require any drilling. If you are planning on towing you will also need a wiring harness item # 119250KIT and a ball mount kit item # C45534.

    I would be happy to help you set your 2022 Lexus RX 350 up for towing.

  • Trailer Hitch and 7-Way for Towing with 2019 Lexus 350RX
    The first thing you need to tow a trailer with your 2019 Lexus RX 350 is a trailer hitch like the # C73DR which is mostly hidden and has great towing capacities. Then for trailer wiring you'd need to start with a 4-way like the part # 118255 which is a confirmed fit. If the trailer does not have brakes you'd need the part # 37185 to convert to a 7-way or the part # ETBC7 with a brake controller like Brake EVN # TK63VR for if the trailer has brakes.

  • What is Difference Between Curt and Draw Tite Hitches for 2021 Lexus RX 450h
    Hey Randy, so the Curt hitch part # C73DR and the Draw Tite part # 75540 that fit your 2021 Lexus RX 450h are both very similar designs that would both work great. The short story here is I would go with the less expensive hitch if it were me since that's the biggest actual difference. But more than that the Draw Tite actually has higher towing capacities so it wins in that regard as well.

  • Will Installing Curt C73DR Hitch Prevent Hands-Free Liftgate on 2021 Lexus RX350 From Working
    We haven't received any feedback stating that installing the Curt # C73DR hitch has prevented the hands-free liftgate feature on the Lexus RX350 from working. What usually happens is that the receiver tube of the hitch blocks the sensors from reading input right at the center of the vehicle, but typically if you wave your foot several inches to either side of the receiver tube, the sensors should work just fine.

    Hey Jerry, thanks for reaching out and for your recent purchase of the Curt Trailer Hitch receiver # C73DR for your 2022 Lexus RX 350! We haven't removed that style of sensor yet, but when I did some research into what that sensor looks like I was seeing that there are 2 screws and some guides that hold it in place. If you remove those 2 screws you should be able to slip the whole assembly loose so you don't cut it while you're trimming the fascia. I don't have any photos or videos of...
