Just the right amount of rise, great fi nish

Well made and liked the dual length mount. Unfortunately needed more lift and went with the Curt aluminum from etrailer. Shaved a few pounds as well.
David - 10/15/2022


Each time we go camping we look for ways to improve the experience, the C45230 will allow us run with a short or long ball mount, the longer extension allows me to open my tail gate without disconnecting from the trailer. I looked at other manufacturers but was only able to find what I was looking from CURT, and etrailer offered the best price.


Looks good. Powder Coat came damaged. Not sure if it has been previously installed into a receiver that would cause the blemish. Farthest hole to pin center is more like 10 1/2". Not sure if I'm able to use. Really needed the 11"+ dimension.

We measure from the center of the furthest pin hole to the center of the hitch ball hole, which is where we get the 11 and 1 eighth inch measurement. Here is an extra long ball mount that we carry, Item # D-26
Ball Mount 3/4" Rise or 2" Drop, Extra Long
, that measures 12 and 5 eighths inch long from center of pin hole to center of ball hole. A Customer Service representative will reach out to you about the powder coat damage.

I recently had gotten a new tow vehicle and my 13' trailer was hooked up to and showed a lift to my hitch and back of trailer was lower. I called etrailer and talked with Cathy T who helped me with my problem. Very Satisfied with outcome.*****


Excellent Product fit perfect.


The ball mount is what I expected, and is a good product. The only downside is that there is too much freeplay between the ball mount and the receiver. I made some shims that I adhesively bonded to the ball mount, which makes for a much better fit.

Hi Philip, Thanks for your feedback! I would recommend using the etrailer Anti-Rattle Hitch Stabilizer, part # e99007
etrailer Anti-Rattle Hitch Stabilizer for 2" Hitches - Vinyl Coated Steel
, to help get rid of the play in the hitch.
-- Etrailer Expert Tyler M - 05/04/2021


This drop ball mount with extension, and the accompanying pin, ball and cover, was exactly what I needed to match my 16' Scamp trailer with my 2017 Highlander Hybrid. The extension allows the tailgate to clear the electric trailer jack. A perfect solution.

Its still solving the problem perfectly.
Lynn - 11/05/2019


Like double length Pin holes. Have Jeep with Spare tire and need extra length to get ball past spare tire to hitch up utility trailer. When not used, use short hole so I do not walk into end of hitch.

All is good, no problems with any products. Like your web site, good prices, products stand test of time. Will use next time needed.
Eddie - 01/31/2019


Does what it should.

I havent used the hitch hardware much but I like it. The tailgate is the star. I like it a lot and the open design makes parallel parking in the city so easy. I also get a lot of questions and nice comments about the look.
Jeff - 10/17/2017


The two hole ball mount for the 2x2 hitch along with a two inch ball was delivered on promptly as promised . The ball mount and two inch ball mounted in the two inch rise position was exactly what was needed to go along with the front trailer hitch which was also purchased from etrailer to raise the coupler to the right height. Before purchasing this new coupler I had to use a screw jack to mount the trailer to the front hitch because the swivel would not go low enough. With this new ball mount I can use the swivel jack to switch between the front and rear hitches. New ball mount did a great job solving my problem, thank you very much etrailer.


Exactly what I needed. My new truck had a taller tailgate that would hit my trailers lifting jack and not open all the way down. With this coupler's extended length pin option everything works fine. Construction looks very robust, finish was good, and priced reasonably.


This ball mount contacts my spare tire when slid in . Had to push hard to get pin into it Took air out of spare to proper 35 psi which helped. 2016 Silverado 1500 crew 2wd.


Ball mount arrived just as described ( even a day early). After consultation and and advice from Nicholas I ordered a new ball mount for my van and trailer. I was a little skeptical but took Nicholas advice and am glad I did as it gives me the drop I needed. Thanks Etrailer & Nicholas


Perfect fit for my Expedition to keep my boat from hitting the taillights in a tight turn


It works well. I originally bought it so I could drop my tailgate with the trailer on, but I mis-measured, so I use it when I don't need the length. Good quality, nice finish.


Heavy duty, good price

Very well, does everything I hoped it would.
Randall - 08/18/2020


Everything was fine.


Replacement part after a rear-end Collision they work great before it works great now


Product arrived as advertised. Good quality.
Very happy with both the On Line and Telephone support that I received.


Good quality, use for hauling, will buy again. Tom


well built, note it is marked 4" drop on product

I am glad you brought this up, Jim. Curt uses rounded measurements on their product stickers. For example, on this ball mount, the sticker reads that it has a four-inch or a two-inch rise. The actual measuring from the top of the shank to the top of the ball platform is going to measure three and five-eighths of an inch, and the actual rise measuring from the top of the shank to the top of the ball platform is going to measure two and three-eights of an inch. I hope this helps.

looks like a quality product, install was a breeze can't wait to test it


Installed easy and works great after 1st year


Awesome and friendly customer service. They were able to upgrade my shipping for free! Order was accurate and arrived quickly.


Good deal for the price . It did take a little long to get

  • Recommended Fixed Ball Mount With Drop For 6,500-Lb Trailer
    Towing the trailer level is the more important thing to keep in mind. If you have a ball mount that has a rise or drop and is rated for the tongue weight of the trailer you are hauling it is fine. A nice ball mount that will take care of the 3-inch drop you need is part # C45230. This ball mount has a 3-5/8 inch drop and has a towing capacity of 7,500-lbs.

  • Longest Ball Mount with 3 Inches of Drop Available
    You didn't say exactly how long you need the ball mount to be but I can tell you the longest one we have with a 3 inch drop is # C45230. It's 11-1/8 inches from the hitch pin hole to the ball hole when used in the longer position.

  • Curt Ball Mount Recommendation that Has 2-3/8 inches Rise and 3-5/8 inches Drop
    We actually used to carry that part number but just discontinued it since it's no longer available. We do have similar ball mounts though. For almost an exact match we have the part # C45230 that has the same 2-3/8 inch rise and 3-5/8 inch drop. Only difference is the back of the ball mount shank is angled which makes for easier insertion into a hitch.

  • 2 inch Hitch Ball Mount Recommendation with 3 inch Drop, 2-5/16 inch Ball and 7,500 Towing Capacity
    We have the Curt ball mount part # C45230 which has a drop of 3-5/8 inches and has a capacity of 7,500 lbs. For a 2-5/16 inch hitch ball to work with this ball mount we have the # 63847 which would fit and work well.

  • Recommended Long Ball Mount with 2 to 2-1/2 Inches of Rise
    The Curt Dual Length Ball Mount # C45230 has a 2-3/8 inch rise and is 11-1/8 inches long when using the second hitch pin hole. However, it is black not chrome. The closest chrome which we carry is the Curt # C45296 which has enough rise at 2-1/4 inches but it's only 8-1/2 inches long.

  • Using Hitch Extender to Increase Turning Radius of V-Nose Trailer Towed Behind RV
    The first thing you'll want to do is confirm the tongue weight of your trailer. I'll link you to an FAQ article that explains how to do this. You CAN use an extender, see link, but keep in mind an extender will lower the tongue weight capacity of your hitch by 50 percent. The tongue weight capacity represents the maximum amount of downward force that can safely be exerted on your hitch. If the trailer tongue weight is less than half the tongue weight capacity of the hitch, you can use...

  • Difference Between Long and Extra Long Ball Mounts
    The long ball mounts like the part # C45230 have around 11-1/8 inches from the center of the hitch pin hole to the center of the ball hole whereas the extra long ball mounts like the # D-26 have around 12-1/2 inches from the pin hole to the ball hole. These categories are ones that we developed to help organize the ball mounts on our ball mount page. There aren't hard and fast guidelines on how each ball mount is organized.

  • Recommended Extended Ball Mount with 3-1/2 Inch Drop
    I recommend taking a look at the Curt Dual Length Ball Mount # C45230 for your application. This ball mount features a 3-5/8 inch drop but also has two separate pin holes that let you change the length of the shank so you can get a bit more extension. When using the second hitch pin hole, there is a distance of 11-1/8 inches from the center of the pin hole to the center of the hitch ball hole. The ball mount has a weight capacity of 7,500 pounds and a ball hole diameter of 1 inch. For...

  • Recommended Hitch Ball Shank Length for Curt Ball Mount for 2 Inch Hitches
    For the Curt Ball Mount for 2" Hitches - 2-3/8" Rise, 3-5/8" Drop - Angled Shank - 7,500 lbs # C45230 you will need a hitch ball with a 1 inch shank that is just over 2 inches long. For a 1-7/8 inch ball diameter, I recommend the Curt # C40002. For a 2 inch ball diameter, I recommend # 40038. These shank lengths of 2-1/8 and 2-1/4 inches will allow for the ball platform thickness as well as the lock washer and nut.

  • Ball Mount Recommendation for a Trailer that Needs a 1-1/4 Rise To Tow Level
    If you can get the ball mount within a 1/2 inch or so of what you would need to be perfectly level you would be just fine. Since you need 1-1/4 inches of rise to tow level a 2 inch rise would be perfect since there is bound to be a bit of rear suspension sag when you hitch up to your trailer. For a ball mount then I would recommend the # C45230 and then for a hitch ball # 40038 for a 2 inch ball or part # C40007 for a 2-5/16 inch ball. I attached the help article you referenced on selecting...

  • 2 inch Rise Ball Mount Recommendation that is 10 inches from Ball Hole to Pin Hole
    The part number # C45230 would be your best option. This ball mound will do 2-3/8 inches of rise which would be close enough for your setup most likely when you take into account a bit of sag from the weight of your trailer's tongue weight. The ball mount is 10-1/4 inches from the center of hitch pin hole to center of ball hole as well. For a 2 inch ball the part # 40038 would be what you need and for a 2-5/16 inch ball part # C40007.

  • Curt Ball Mount with Drop Near 3-1/4 inch
    The closest we have is the Curt part # C45230 which has a drop of 3-5/8 inches or the # C45154 which has a 3-1/2 inch drop and a 2 inch ball or part # C45151 which has the same drop and a 1-7/8 inch hitch ball.

  • How to Select Correct Ball Mount to Allow Towed Trailer to Remain Level
    You ask a good question. It is important to select a ball mount for your towing set-up that allows the trailer frame to be level with the ground when it is hitched to the tow vehicle. Level trailers handle better and tend to have less sway. With that said, it is generally a good idea to start out with your tow vehicle's hitch ball sitting a good inch (or maybe a little bit more) HIGHER than the trailer coupler. This height difference tends to compensate for the normal rear-end squat on...

  • Can Roadmaster Anti-Rattle Hitch Extender be Used for Towing Travel Trailer
    If you are needing to extend the gap between your tow vehicle and trailer, the Roadmaster Anti-Rattle hitch Extender # RM-071-1075 referenced in your question will provide a great solution. This is compatible with any 2 inch hitch receiver and will move the receiver opening 7-3/4 inches out from your trailer hitch. Please note that the use of this or any similar hitch adapter is going to reduce the tongue weight capacity of your trailer hitch by 50%. For example, if the trailer hitch on...

    For the 2012 Jeep Liberty, I recommend the Curt Trailer Hitch # 13245. This is a Class III rated trailer hitch with a 2 inch hitch receiver. This hitch has a maximum gross trailer weight of 5,000 pounds, but I recommend checking your vehicle's max towing capacity before choosing a trailer and cargo to tow. The Curt hitch has the same quality construction and capacity as the other choices, but with a more economically friendly price. I have attached an installation video of this hitch on...

  • How to Extend a Class III, 2 Inch Trailer Hitch at Least 24 Inches
    The longest hitch extender for 2 inch hitches is 18 inches long, # C45796. If you use it with a long ball mount, # C45230, it would provide and overall extension of about 29 inches. Please note that the use of an extender will reduce the tongue weight capacity of the trailer hitch by 50 percent at least. If you were to use the ball mount only it would not reduce the tongue weight capacity. But by using an extender it does reduce the capacity.

    You've got good instincts. I recommend going with a ball mount that has a 2 inch rise for the exact reason you mentioned, the truck will settle a bit with the tongue weight and any cargo weight. The ball mount we offer with a 2 inch rise is the Curt Class III Drawbar # C45270. This is considered an extra long ball mount, measuring 13 inches from the hitch pin hole to the ball hole.

    I took a look at the online version of the owner's manual for your 2015 Honda CR-V and it lists a maximum trailer weight of 1,500 pounds. Based on my research the 13 foot Scamp trailers can weigh between 1,300 and 1,600 pounds. Since this range does push and potentially exceed the limits of your CR-V I highly recommend verifying the camper's GVWR, which is the most the trailer can weigh when fully loaded, with the Scamp dealer before making a purchase.
