2021 Toyota RAV4

Took about 15 minutes to install. Very nice. Cannot go wrong with etrailer. Thanks!!!! Great products.

2022 Toyota RAV4

After reviewing the installation video, my husband and I (we are both seniors) were able to install this item fairly easily.


Loved the hitch I purchased for my vehicle,so we got one for my husband's suv. Gives us lots of extra storage for camping gear. Bike Attachment is amazing for exploring our local trails.

2019 Toyota RAV4

I have ordered twice from this company. Since I just bought a new car, I needed a new hitch for the bike rack I had ordered previously. Customer service remembered me and answered the questions I had.
I haven't installed it yet, but the videos are helpful. I am sure it will fit just like the other one. I will deal with this company for all my needs in this area.


Man, super fast delivery...two days. This hitch was pretty easy to install. Recommend you get the bolts on the passenger side going before you do driver side. Much easier to manipulate hitch once passenger side is in. Etrailers has been top notch with notification and delivery.

2020 Toyota RAV4

I have never had such a hard time installing any product in my live. The rav4 HYbird has no FINGER SPACE to get the bolts in on the battery side. I had to use the bolts that I removed from the plate I removed cause I could not get the bolt started. The alinement was great. The product design should have been to where the bolts go under the frame not the sides for Hybirds.
Sad, Im 72 and


This is the second one of these hitches I have purchased for two different cars. It does exactly what I need it to do. Simple, sturdy. Perfect.


It came right away and I'm just waiting to have my mechanic install since I'm not handy. I've used etrailer for my last hitch for my subaru and it was awesome. I highly recommend etrailer. Great customer service!


I bought this hitch to mount on my 2021 RAV 4 Hybrid so I could pull my utility trailer and to hold my receiver style bicycle rack. So far, I have only used it to transport bikes and it works great. The hitch was relatively easy for one person (me) to install in about two hours and it looks good, i.e. not very noticeable.

2021 Toyota RAV4

It seamed of very good quality. I have no mechanical skills, I am a female, 74 years old and 125 pounds. I installed it by myself. Of course, it took longer than normal. I held it up by stacking encyclopedias under it one at a time on each side until it was the right height. Then I put the bolts in. It was tight working space, especially on the passenger side. Even with buying a torque wrench, I saved $xxx over the price I was quoted for unit & labor from a mechanic shop. There was not room to use the torque wrench with the socket on the passenger side and I did not have to lower the muffler.

2020 Toyota RAV4

The product is great. very sturdy. Will use this mainly for my bike rack. Installation was the challenging one. Gave this a 4 rating due to the installation document not really clear about the muffler that needs to be pulled side to side to slowly insert the hitch. Had to call customer support and good thing a video was shared. That was all I need. Customer support was an easy 5 rating for sure!


The installation was a snap if you have access to a hoist. I did & I dropped the rear three exhaust hangers & put a jack the exhaust pipe. Then I lowered the muffler about 8 inches & slipped the hitch in place. I was done with the assembly & out the door in less than 20 mins.


Top notch company. They provide advice on what to buy. Then they provide a video for the item that you want for installation on the car that you have. The price is as good as anyone else and the shipping was free with tracking. Could not ask for a better experience.

2021 Toyota RAV4

Installation went about as expected. No unexpected difficulties. The one side is hard to get to and took a little more time as anticipated. My friend had crow's feet, and these really helped in that area. Definitely a two-person job. When you remove the adhesive that covers the holes on your vehicle go ahead and clean the holes with compressed air or a brush. That will speed up the process a bit. Can't wait to use this.

2020 Toyota RAV4

Hitch receiver 1-1/4" is installed and ready for use. Ran into couple of issues during install on our Toyota 2020 RAV4;
1. we had to unmount the exhaust suspension to make some room
2. bolt clearance on drivers side was very tight


The hitch was easy to install except on the passenger side. Very tight on that side. The hitch was delivered very quickly and arrived in good shape. I will recommend Etrailer to everyone.


Well built, fits great! Super easy. Get yourself a 19mm or 3/4 ratcheting wrench for the install.

Still works great! I’ve always had good luck with Curt products and trailer when I ran a repair shop.
Trevor - 07/10/2022

Toyota RAV4

Delivered quickly, seems to have installed cleanly. Works well so far as receiver for bike rack on our RAV4.


Beautiful work, just received the hitch yesterday, not installed yet but looks to be perfect!
Thank you once again.

2021 Toyota RAV4

took about a half hour to install, fir perfect

Good no complaints
William - 11/12/2021

2021 Toyota RAV4

Fit perfectly on our RAV4

We are still using it in spite of the fact that a truck backed into the bike rack attached to the hitch while the car was parked. The rack bent a little, while the hitch showed no damage.
Barry N - 08/07/2022


Great hitch, very simple to install and quite solid. Super value.


Great value for the price

2021 Toyota RAV4

Pretty simple installation, if you have the right tools. I ran into every 'heads up' scenario highlighted in the video and other reviews. The passenger tie down was in the way, definitely check before lifting up the hitch. The passenger side is really tight, so do yourself a favor and get a ratcheting 19mm wrench. I did not have to lower my exhaust, but if I tried to install this by myself, I definitely would have. Total install time was about 45 minutes. 30 was on the passenger side, since I don't have the ratchet wrench.

2021 Toyota RAV4

This hitch went onto a RAV4 Prime XSE with premium package without issues. The key to installation is to angle the front (relative to the car) of the hitch up at around 45 degrees while fitting it between the exhaust. As others have said it's moderately tough to bolt the left side due to the proximity of the car body. That said, the hitch is on and did its job with a 4-bike carrier this weekend. I don't know if the kick sensor still functions; I disabled it to avoid any accidental triggering by the hitch or accessories.

  • Will Curt Class II Trailer Hitch Receiver C66KR Stick Out Past Bumper On 2019 Toyota RAV4
    When we had a chance to install the Curt Trailer Hitch Receiver # C66KR on a 2020 Toyota RAV4 we found that the trailer hitch receiver will be roughly 2" recessed from the most outward part of the rear bumper. I am not sure exactly which part of the bumper the receiver cannot stick past, since as you can see in the included picture the hitch will stick past the bottom lip, but it will not protrude the main portion of the bumper of your 2019 Toyota RAV4. I included a video of the # C66KR...

  • Best Ground Clearance Trailer Hitch that Fits 2021 Toyota RAV4 Prime
    Yes the hitches from the 2021 Toyota Rav4 Prime are the same as the 2022 Rav4 Prime. The Curt hitch part # C66KR fits right up to the very bottom of the rear bumper so it would have the best ground clearance. I attached an install video for more info for you to check out as well.

  • Can Curt Hitch C66KR be Installed to Avoid Interference With Liftgate Sensors
    In short, no, there isn't a way to 100 percent guarantee the hands-free liftgate on your 2021 Toyota RAV4 will function exactly the same after installing any trailer hitch, including the Curt Trailer Hitch Receiver # C66KR. There isn't a different installation method for the # C66KR which negates the possibility, but I will say that I haven't heard of this happening with this hitch. What happens far more often than not when there is this warning is that you just have to kick your foot...

  • What is the Difference Between the Ground Clearance of the Curt # C66KR and the Draw-Tite # 36675?
    If you are looking at the Curt Hitch # C66KR and the Draw-Tite Hitch # 36675, both of these 1-1/4 inch hitches have ground clearances of 12 inches. Ground clearance is measured from the ground to the bottom of the upper part of the receiver tube opening. With these two options, I recommend the Draw-Tite hitch because it is the more economic option. I went ahead and attached videos of both of these hitches to walk you through the installation process on your 2021 RAV4.

  • 1-1/4 inch Trailer Hitch that Fits 2021 Toyota RAV4 Prime PHEV
    The Draw Tite hitch part # 76201 does fit your 2021 Toyota RAV4 Prime PHEV but it is the wrong size as it is a 2 inch hitch. Instead you'd want the Curt hitch part # C66KR which also fits your vehicle but is the correct 1-1/4 inch hitch size.

  • Difference Between Installation Difficulty of Curt and Draw-Tite Class II Hitch for 2021 Toyota RAV4
    After looking through the installation instruction for the Curt # C66KR and Draw-Tite # 36675 Class II hitches for the 2021 RAV4, there really is no discernable difference in the installation procedure that would justify the difference in install difficulty rating. In my opinion, neither would be any more difficult to install than the other. Since both hitches install in the same manner and have the same capacity, you could choose the least expensive option, and not feel like you've sacrificed...

  • Installation Video For The Curt Class II 1-1/4 inch Hitch Receiver On A 2019 Toyota Rav4
    I have attached a video of an extremely similar hitch to the Curt Class II 1-1/4 Hitch Receiver # C66KR. Its the Curt Class III 2" Hitch Receiver and its being installed on a 2019 Toyota Rav4. It has the same mounting points and will require the same steps to get it installed. The only difference is that it's a Class III 2" instead of a Class II 1-1/4" hitch receiver. Rob does a great job explaining so you'll be confident doing this at home!

    The installation of a hitch like the # C66KR will not interfere with the power liftgate on your 2022 Toyota RAV4 Hybrid. The only thing it may impact is the hands-free sensor. So your key fob and the button will continue to work as intended. However, I would recommend installing a Class III hitch like the etrailer Trailer Hitch Receiver # e23ZR over the Class II hitch.

  • Class III Vs Class II Trailer Hitch For A 2021 Toyota RAV4 Hybrid
    The main reason you should use a class III hitch vs a class II hitch is that a class III hitch like the Curt Trailer Hitch Receiver # C13416 has a 2" x 2" receiver opening which is the most common opening used and manufactured, to carry hitch mounted accessories like the Swagman Trailhead 4-Bike Rack # S63381. Also, class II hitches are not made to be used with a weight distribution system, so if you wanted to use a WDS you'd have to install a class III hitch. That being said, there isn't...

If the only hitch accessory you'll ever use is that particular bike rack, I'd just go with the Class II.

  • Draw-Tite vs Curt hitch for Bike Racks on 2019 Toyota Rav4
    Great question! First off, your Toyota Rav4 can handle 1 1/4" Class II or 2" Class III hitches. In the Class II category, both hitches are very similar in specs and capacity. The Curt Class II Hitch # C66KR is slightly easier to install than the Draw-Tite Class II # 36675. For your Class III hitches, you have the Draw-Tite # 76201 and the Curt # C13416 hitches.

This will give you a 2" receiver for a Hollywood Racks Sport Rider # HLY84FR. Do note that the adapter does reduce the receiver capacity by 50%(350lbs to 175lbs) and cannot be used with trailer towing.
