I neeed to pull a trailer with my 2019 GMC Yukon. I found and followed the instructions on determining the drop of the hitch, the instructions were spot on. I hooked up my trailer to my Yukon today, all was level and worked perfectly.

I had driven around to Napa, Lowe’s, Home Depot and Walmart, and nobody had the 9” drop hitch I needed. Came back to Etrailer, bought the 2” ball and pin, and the Curt 9” drop hitch. I received the items quickly.

Great website,




The quality of this product is fantastic and it assembled with no problems and makes my rv / toad I pull a perfect match. I will continue to do business with ( much more in the future. The following photos are of my 1988 Fleetwood Jamboree and my baby (rare 1982 Toyota Corolla Station Wagon) all connected up and the 9" drop towing bar makes my Toyota towing very easy and safe at a level condition with my RV. Also look at the new LED lights installed to dress up my older RV, also purchased from I am a happy camper and highly recommend purchasing from them.


I have purchased numerous items from Etrailer for several years and I have never had a negative issue. Quality products with quick delivery. I do not focus on shopping around for the lowest cost because I am a quality person. I will continue to purchase any and all trailer towing related parts from


With my 2015 Yukon Denali I needed a 9 inch drop trailer hitch ball mount for my utility trailer. The one I found on (C45112) is great. Heavy duty, great finish - still like new after a year of use.

Great product. Sturdy and very well made. Perfect for what I needed.

Put the boat trailer at the correct level. Makes the tow much better.


Was having a hard time finding the correct drop for my motor home, Etrailer had it in stock and shipped it out the same day I ordered it!


They accidentally sent the wrong ball mount due to some miscommunication. Chrissy who helped me was awesome every step of the way. I returned the ball mount and recived the correct one within a week. Excellent customer service in my opinion. Very satisfied with my purchase and give a big thumbs up. A+++++++ service.


Due to COVID travel restrictions and health issues we have not been able to actually use the ball mount. It was a perfect fit for our motorhome to auto trailer and the trailer was level with this extended hitch. Some day we will actually use it...


The 10" (9 3/4) drop is the right fit for my 2021 Ford Ranger and 6" X 12" Gator Made Trailer. Trailer is now level. Thanks


My trailer rides level now on my 6" lifted Silverado with this lower mount.


Biggest issue is that NO ONE warns a potential purchaser of FIT! Tolerances matter. First time I used this ball mount I couldn't believe rattling. I have a 5x8 enclosed trailer and was pulling with my Explorer. Had to deliver a piece of furniture 17miles away for repair. I last 3miles was down a gravel road and OH my God, I slowed to a crawl, but still thought I was going to destroy my factory installed receiver. Called Curt and they had me get calipers to measure the receiver opening to the thousandths of an inch! And yes, there was too much difference between receiver and ball mount shaft! If I would have been apprised of this issue I'd certainly done some pre-purchase measuring. You can buy ball mounts at any auto store, or Walmart even and there is NO warning of this issue!!! Curt sent an anti-rattle fitting to me. Yes, they know about this issue. It helps some but is not perfect. It helps to minimize horizontal movement but not so much on vertical. But better than before. Ironically, the ball mount pins I bought from e-trailer and reviewed above can't be used with the anti-rattle fitting! So, there was some money [thrown] away. Lastly, I've had ball mounts before for other vehicles and NEVER had a rattling problem. Probably because I had everything installed at a trailer retailer. And none of the ball mounts I had were extremely heavy. This Curt ball mount is very very heavy. I did need a greater drop for my Explorer and existing trailer, and maybe over shot by one inch. But this thing could be used a great weapon.


Makes my log splitter ride level behind my atv now!!


recently raised dodge ram 1500 laramie shortbed for heavy 4x4 and , since it was set-up by mopar as a trailer puller model, got trailer ready for trips. it sets high needed a dropped hitch mount for lower trailer - ehitch had that perfect mount. im satisfied, great niece travel companion is estatic. cant get any better


The hitch gave me the exact recommended height that I needed for my Acme tow dolly (14 inches) behind my motorhome.

just the right size


Purchased trailer hitch, ball, and lock pin. Needed a 9 1/4 " drop. etrailer had the parts in stock at competitive prices. ordered on a Sunday arrived Wed noon. Great response time on any items I have ever ordered. I like these folks!


Before the knowledge of etrailer is was all ways a epic struggle to address anything related to trailer and towing.
I would recommend to anyone.
It is worth the wait
They have the answers.
This curt product for the app I needed worked excellent. I needed it for a rise,and it came within the 1 inch for what was need.
Very strong and paint appears to be very strong.
Excellent products and excellent service.


Completely satisfied with product performance and eTrailer Corp’s action to upgrade my shipping to 3-5day delivery providing me the opportunity to start my fishing season at least 1week earlier than expected!
The Curt hitch performed beyond my expectations for quality and workmanship!

Thank you eTrailer!!!


Quick shipping especially since its a heavy device. Prior to buying had a couple of questions about other my needs and options and was promptly responded to. etrailer had the product I was looking for, hard to find 9" drop ball mount.

The product showed up 2 days later & before I needed it (had my doubts). And it came in as they published. Extremely happen with the service from etrailer. Easy buy.


The video showing the measurements helped a ton with the faq on choosing how much of a drop you need. Came out perfect for my truck.


I bought this hitch because I needed to lift my trailer 8" to make my pontoon trailer level. The hitch did just that and my trailer sits level when hooked to my truck. I have not yet put my boat on the trailer to pull it but expect all to go smoothly.


Arrived on time. The mount had slight wear. Mainly some scuffing but nothing to change my mind in the purchase I expect it'll receive more in the years to come.


My truck sits quite high in the back and my trailer likes to be towed level as the contents are sensitive so I needed a very large drop. Ordered from E trailer and it was delivered very quickly undamaged good price and good service. I have no photo to share


The item is exactly want I expected. I ordered it on Mon. and etrailer upgraded my shipping at no extra cost and it arrived on Wed. ......Now that is some Rocket Fast Shipping ! You can call me a completely satisfied customer. Thanks, RR


This hitch is exactly what I was looking for. Most are either an 8" or 10" I needed a 9" and this is very close. It arrived today and I was very impressed with quality of the product and the packaging. It arrived in great shape considering its weight. It also arrived sooner than I expected. Great product and service. thanks

See what our Experts say about this CURT Trailer Hitch Ball Mount

  • How to Pick Out Correct Rise/Drop Ball Mount for Van Towing Trailer
    I attached an FAQ that details how to pick out the correct ball mount for you to check. Basically picking out the correct ball mount will allow your trailer to sit as level as possible. If you need more clearance and your trailer is sitting low up front then going with a higher rise would what you'd need. But if you are already level we can't recommend using a higher ball mount since your trailer won't ride properly with the nose pointed in the air. Basically you will first measure the...

  • Why Does Curt Ball Mount part # C45112 Have Higher Capacity in Drop Position
    If you look at the support bracket that is welded behind the ball mount platform of the Curt Ball Mount part # C45112 it provides more support in the drop position than in the rise. When in the drop position the bracket works to support ball mount and it's mainly the metal of the bracket that is doing this. When in the rise position that bracket is really only adding the strength of the welds of the bracket to prevent it from bending down. That's why it has a higher capacity in the drop...

  • Ball Mount Recommendation for 8 inches Of Rise
    8 inches of rise would be exactly what you'd need to tow your trailer level as long as the hitch measurement you took was from the top of the hitch opening to the ground. For that we have the part # C45112 which has 8 inches of rise and would work well.

  • What is the Difference between Curt Ball Mounts C45112 and 45110
    Curt ball mounts # C45112 and 45110 are essentially the same with a slight difference in overall length. The C45112 is 14 inches long and the 45110 is 13 inches long.

  • How to Pick Out Correct Drop Ball Mount for a Ram Truck with 6 inch lift
    You actually will have to be the one to determine the amount of drop you would need but I can easily explain how to do this. You will need to measure from the top of your hitch opening down to the ground and then measure from the bottom lip of your coupler to the ground on your trailer when it is sitting totally level. The difference between these two numbers is the amount of drop you would need. With that info check out the link I attached where you can pick the drop you need from the filters.

  • Distance From Hitch Pin Hole to Gusset on Curt Ball Mount C45112
    Yep, you're exactly right; the distance from the center of the hitch pin hole to the welded gusset is indeed four inches on the Curt Ball Mount for 2" Hitches # C45112. So if that's the amount you need for it to work without hitting the bumper then you're set.

  • How to Increase Height of Trailer Hitch Ball to Allow Boat Trailer to be Towed Level
    Ideally a hitched trailer will be level to the ground. We often recommend starting off with the hitch ball being a bit higher - an inch or so - than the top of the coupler on the level trailer since once hitched there will be a degree of squat in the rear of the tow vehicle from the trailer tongue weight. This is perfectly acceptable. You can select a different ball mount for your hitch that gives you additional height (rise) by using the link provided at right. For example, if you want...

  • Adjustable Ball Mount Recommendation that Can be Used with Cruisemaster DO35 Coupler
    Since the Cruisemaster DO35 requires a ball mount platform with a 1 inch diameter ball hole you'd need an adjustable ball mount that uses a traditional style of ball mount platform like the Convert-a-Ball Adjustable-Height Ball Mount # TK5007 which would work well. This can do up to 10 inches of drop or 9 inches of rise. I attached a review video for this ball mount for you to check out as well.

  • How to Pick Out Ball Mount for Lifted Truck Towing Trailer
    The amount of drop that a ball mount needs is based on two measurements. The distance from the top of the hitch opening to the ground and from the bottom of the coupler lip to the ground on the trailer. Comparing those two dimensions will get you the amount of drop you need. The other option is to go with an adjustable ball mount which is also helpful for future trailers as well. We have the B and W Tow and Stow ball mount part # BWTS10049B which can do up to 7 inches of drop and comes...

  • Recommended Ball Mount with Correct Drop to Tow Trailer Level
    It sounds like you need a ball mount with a drop of at least 8 or 9 inches. A couple options are the Curt # C45090 with 8 inches of drop and the Curt # C45112 with 10-1/4 inches of drop. Another option since you're not positive exactly how your trailer is going to sit when hooked up is to go with an adjustable ball mount. The Weigh Safe 2-Ball Mount # WS10-2 will give you up to 10 inches of drop so you have the ability to choose the best height for your trailer. This also has a built...

  • How to Determine Correct Ball Mount To Keep Towed Trailer Level for Best Handling
    There's a simple way to determine how much drop (or rise) you need from a ball mount in order to keep your towed trailer level. A level trailer handles better so you're wise to get it right! Please refer to the linked article. This explains how to measure the hitch receiver height on the Highlander and also the coupler height on the level trailer. The difference between the two is the drop or rise needed in the ball mount. Hitch height - trailer height = drop; trailer height - hitch height...

  • Explanation of What for Flat Tow Use Means on the Blue Ox High-Low Adapter
    When the Blue Ox High-Low Adapter for Tow Bars # BX88131 says that it is for Flat Towing only, it is referring to a different type of towing. Flat Towing is when you pull a vehicle behind a motor home using a tow bar like the Blue Ox Alpha 2 Non-Binding Tow Bar # BX7380. The tow bar comes from the motor home to the vehicle, the high-low adapter you are looking at is designed to keep the tow bar level with the vehicle. So it is designed when a motorhome is pulling a vehicle, not when a vehicle...

  • Parts Needed To Tow a Trailer Using EcoHitch On 2016 VW Golf R
    The EcoHitch Hidden Trailer Hitch Receiver part # 306-X7332 is an excellent option for a 2016 Volkswagen Golf R. It can be used for towing but you'll also need a trailer wiring harness and ball mount/hitch ball. For a trailer wiring harness, I recommend the Curt Powered Tail Light Converter part # C59236. For the ball mount/hitch ball, you'll need to measure to get this right. I have attached an article below. If the Curt Ball Mount part # C45112 ends up being correct you can use the...

  • Hitch Solution for 2015 Volkswagen Golf GTI that Can Do Ball Mount Rise of 9 inches
    I really wish there was a good solution for your problem but with Class I hitches like what you have there isn't a way to use a taller rise ball mount. The added length and leverage of the taller ball mount just is too much stress on the lower capacity hitch. Aside from going to a 2 inch hitch I really don't have a solution I can provide.

  • Hitch Adapter to Raise Bike Rack
    There are no hitch adapters that offer just rise for a 1-1/4" hitch. What bike rack do you have? If it is one we carry we may be able to find you something to convert it to a 2" rack, or there is also the possibility of a new rack with a shank that has rise. If you let me know what rack you have I may be able to find a solution for you.

  • How Can I Transport My 14 Ft. Laser Sailboat on My 2016 Honda Fit?
    I have a great solution for that will work with the weight/length of your 130-pound Laser Sailboat on your 2016 Honda Fit. Unfortunately, with the approximate 125 pound maximum weight capacity of your roof, you will not be able to adhere to the roof rack weight limit since it exceeds the roof capacity. With that being said, the safest way to transport your sailboat is by trailer. I recommend the Yakima Rack and Roll Trailer - 66" # Y08106. With the Rack and Roll trailer, you will have...

  • Recommendations for Carrying 4 Kayaks on a 2017 Ford Escape
    Carrying 4 kayaks on a vehicle roof is going to require a special type of carrier and the kayaks would have to be carried on their sides directly on roof rack crossbars. The first thing you will need is a roof rack that includes crossbars that run side to side if your 2017 Ford Escape does not already have one. I have included a link to the roof rack main page for your vehicle. There are 2 roof options listed, not existing rails or crossbars and factory raised rails. Choose the type that...

    We can definitely help you out, and you are right about the factory tow package hitch on a 2019 Jeep Wrangler Unlimited being a Class II hitch, though it also has a 2 inch receiver, which is an odd combo not seen on aftermarket hitches. That said, if your current hitch is bolted on (and not welded) I highly recommend replacing it with an aftermarket hitch, the Class III Draw-Tite Trailer Hitch Receiver # DT78MR.
