I installed this on my 2015 Honda Accord for the purpose of pulling my small aluminum fishing boat and trailer. Works great!




by:

It's a ball mount designed to fit Curt hitch 12284 - Subaru Crosstrek. Rise and extension with that hitch are correct. Only complaint are the paint chips and scratches when it arrived.




by:

It has performed well for several thousand miles of towing. I would like to see the tolerance between the bar and the hitch a little tighter. When towing you can hear the movement of the drawbar inside the receiver.




by:

Ordered a Curt trailer hitch receiver to mount on a 2003 Dodge Caravan to pull an old Scamp trailer. Came promptly, installed easily and works well.
Thanks




by:

I received what was ordered but it seems like it will be too low for a trailer. I called the company, and the lady was very professional. She verified that I had the correct part and sent info to me on measuring rise & drop for the hitch. I haven't purchased a trailer yet so I will re-order if needed.




by:

Wonderful product. I had the hitch installed in 10 minutes. The wiring was a little more tricky because it required running a power wire all the way to the battery. I towed my trailer from Florida to Tennessee and back. Etrailer is still wonderful to deal with as they always have been in the past. My hitch came in a couple of days. I wouldn't think of ordering from any one else.




by:

Easy installation,solid design.

See trailer ball review. Works great

I ordered a receiver for a 2014 Subaru Impreza, and a drawbar and hitch cover. The package arrived a bit beat up, but nothing was missing or damaged. I intend to use the receiver for a bicycle mount and the drawbar (with an eyebolt) as a rear tie-down for kayaks and probably won't really tow anything.
The online video on how to thread the carriage bolts and anti-spin washers was excellent as were the printed instructions. The fish wire (two different ones) was included and was 'threaded' or coiled to hold the threads of each bolt quite firmly. The stiffness of the wire was perfect.
I used a 'step drill' to enlarge the two front holes in the frame (these new frames aren't made with a real heavy gauge metal, btw) The step drill made a near-perfect round hole vs a Dremel type device that others have used, but either would be fine. Wear goggles to protect your eyes from flying metal shards, please, but don't be intimidated by the project! You will most likely need a helper; my wife threaded the nuts on the bolts while I held up the roughly 30 pound hitch. I also gooped the top of the hitch with black silicone caulk to waterproof the connection. I had no need for the spacers and the receiver was about a half inch from the bottom of the bumper and flush -to -slightly- in from the back of the car.
Etrailer does offer tracking now, so earlier criticisms--if valid then--have been acted upon. Delivery to Cleveland area from Mo. was two to three days. I just wish they offered a device for the front area of the vehicle for tie-down lines for the kayaks (hint, hint, but I have a plan for that).
Secure and satisfied.

by:

Good part, but won't fit with Focus ST and big exhaust tips!




by:

etrailer is smart. They ask for a review a year later and not 10 minutes after you buy the product. That gives you a chance to install it and use it. This receiver has done as I expected. It was an easy install and works well. The only downside to date was me. I left the hitch attached to the car/receiver and a guy walked around my car, kind of close to it and tripped over the ball mount/draw bar. Ouch!!
Love etrailer and my hitch assembly.




by:

I was surprised how fast i got my order . Catherine helped me make sure i had the right part , it fit perfict and was easy to install just like she said . I will forsure tell my friends about etrailer and service / & quality of product . Thank Rick PS You guys made my day !




by:

Just a note you have to get a hitch pin separate. It did not come with the hitch or drawbar.




by:

Shipping was horrible. Thank God it didn't fall out of the box when shipped!


Comments
I am sorry to hear how the packaging was received. We do our best to package the orders so that they will arrive to you in good condition. I will have our customer service team reach out you.
-- Etrailer Expert Jenny N - 08/13/2022


by:

I spent around $175 for a what I thought to be a complete hitch installation and apparently the lousy $2.00 receiver pin was too much cost for etrailer to include. So now I get the pleasure to travel 25 miles to buy that pin locally. Amazon looks better every day.


Comments
Our description states that the hitch pin and clip or locking hitch pin is sold separately. This is to allow our customers to choose the approiate lock that they may need, or mayalready have for their accessories. If you would like the standard hitch pin that would be used for this item is a F-4. Or a locking version as part C23517.

what a great product. the paint is fant astic.




by:

It's a good product easy to install




by:

Always fast and reliable with a full product line




by:

i placed an order through etrailer and received the first shipment on time as expected, though after trying to install the receiver I realized that it was for the 4 door version of my car instead of the coupe. I called them instantly and within 5 minutes of talking to their customer service i had a new receiver on the way to my door step. The customer service here is amazing and they do their best to take care of their customers. The new part was received and fit just as intended. it is high quality and looks amazing!!!! I would recommend them for any and all trailer needs.




by:

Easy yo install looks great strong build




by:

The product came as the order indicated it would be.

However, since the hitch is my son's and he will use it on an ATV trailer connection, it has not been tried out yet. I think it will be the solution that he has been looking for. The ATV and trailer are at the son's cabin (about 1.5 hr. drive) and will be another week or 10 days before we test out if the hitch will work. I will send feedback after that.


Comments
The hitch and ball mount have worked out great for me no issues.
Wallace - 08/16/2016


by:

Just what I expected. Both work great. And the little aid on how to choose the correct rise or drop was very helpful.




by:

Fit my car and easy to install and good instructions included well made would buy again.




by:

etrailer does a great job of customer education.I would recommend them to anyone.

  • Will Curt Ball Mount C45521 Fit a 2014 Subaru Outback with Class I Trailer Hitch
    Ball mount # C45521 is compatible with Class I and II trailer hitches with 1-1/4 inch receivers. So it will fit the hitch. Usually though on Class I and II trailer hitches you have to use the ball mount indicated by the hitch manufacturer or it could void the hitch warranty. If the hitch is an OEM hitch then you will need to check with the dealer. The issue is that on Class I and II trailer hitches they test and rate the hitch using a specific ball mount. The use of a different ball mount...

    I went out to our warehouse to measure the distance from the center of the hitch pin hole to the back of the shank on the Curt Class II Drawbar, # C45521, and it is 1-1/2 inches. I have attached a picture to illustrate my measurement.

  • How to Pick Out a Ball Mount for a 2014 Subaru Forester to Tow Trailer Level
    When picking out a ball mount for a vehicle like your 2014 Subaru Forester you want to go with the ball mount that will allow the trailer to be towed as level as possible. To do this you will need to measure from the top of the hitch opening to the ground and then with the trailer as level as possible measure from the bottom of the coupler to the ground. The difference between these two measurements is the amount of rise/drop you will need. I attached a help article that covers how to...

  • Availability of 1-1/4 Inch Ball Mount for 50mm Hitch Ball with 1 Inch Diameter Shank
    I do have a solution for you, however all of our available ball mounts for 1-1/4 inch receivers feature a ball hole diameter of 3/4 inches. I recommend simply going with a new 50mm hitch ball like the Draw-Tite # 63912, which features a 3/4 inch diameter shank. You can then pair the ball with any 1-1/4 inch ball mount we have available, such as the Curt Class II Drawbar # C45521. This ball mount has a towing capacity of 3,500 pounds and a rise of 2-5/8 inches or a drop of 3-1/4 inches....

  • Class I and II Trailer Hitches and Accessories are 1-1/4 Inch
    Class II trailer hitches and accessories all have 1-1/4 inch receivers/shanks. Class III accessories and hitches are 2 inch. If you have a Class I or Class II trailer hitch then you are supposed to use the ball mount recommended by the trailer hitch manufacturer for warranty reasons. If you have a 2004 Scion xB then all of the hitches for it are Class I trailer hitches and you should be using ball mount # C45521. I have included some links on hitch classes and ball mounts for you.

  • Is Fishwire Tool Included With Curt Hitch For 2001 Honda Civic
    The Curt Trailer Hitch, part # C11204 has the fishwire tool needed for installation of the hitch. This hitch has a 1-1/4 X 1-1/4 inch receiver opening, and is a Class l hitch, and is a good fit for your 2001 Honda Civic 2 or 4 door if it is not a hatchback. The hitch will not fit Si models. All non-trailer loads - bike racks, cargo carriers and so forth - should be supported with stabilizing straps. Failure to properly support these loads will void your hitch warranty from Curt.

    The Curt Class I Hitch # C11367 that you referenced does indeed fit the 2014 BMW 328d sedan as long as the vehicle has a single muffler. Installation will require temporary removal of the bumper and heat shield. This light-duty hitch will bolt on using included hardware and the only specialized tool needed is a torque wrench.

  • Recommended Ball Mount Recommendation for Use with Curt Hitch on 2018 Honda Civic
    The problem is that Class I hitches like what you have require you to only use the recommended ball mount for that hitch. This is due to the lower capacity of the hitch not being rated for added leverage of a higher or lower ball mount. With the Curt hitch part # C11604 that you referenced you have to use the # C45521 which has a 2-5/8 inch rise.

  • Hitch and Ball Mount Recommendation for a 2015 Honda Accord
    I spoke to my contact at Curt and he informed me that the Curt Hitch part # C11681 that you referenced has been confirmed to fit all models of the 2015 Honda Accord so it would work great on your 2015 Honda Accord Sedan Touring. The recommended ball mount with this kit is the part # C45521 which has a 3/4 inch ball hole diameter. Whether or not this would be an ideal solution for carrying an American flag will depend a lot on the size of the flag and pole you plan to use.

  • What Ball Mount to Use with Curt Hitch C11402
    With Class I hitches like the # C11402 you have to use the recommended ball mount from Curt which is the part # C45521. Using a different ball mount would potentially damage the hitch since the length would be different and the leverage might cause damage.

  • Trailer Hitch and Wiring Recommendation for 2018 Honda Fit
    Offically Honda states your 2018 Honda Fit is not rated for towing a trailer. Since people will still tow and there is a demand for a hitch for your vehicle we have a hitch like the Curt part # C11406 which is a confirmed fit as well as trailer wiring like # 118767. For a ball mount you'd need the part # C45521 as well.

  • Trailer Hitch for 2016 Honda HR-V to Tow Trailer for Scooter
    Since the hitches available for your 2016 Honda HR-V are lower in capacity like the Curt hitch # C18145 which has a tongue capacity of 200 lbs which would be too close to the weight of your scooter. Best option would be to tow a small trailer with your vehicle. To do that you'd also need trailer wiring like the Tekonsha part # 118673 and a ball mount like # C45521.

    The Curt # C45521 drawbar you referenced is compatible with a 1-1/4 inch receiver, as is the # F-4 hitch pin and clip. You'll want to make sure that the hitch on your Escape has sufficient capacity to handle the pop-up you're planning on towing. The first thing I'd recommend you do is to determine the capacity of the hitch. The hitch should have a sticker on it telling you if it's a Class I or a Class II hitch. A Class I hitch will have a towing capacity of up to 2000 lbs, and a tongue...
