- C45338

First, I appreciate William, and his customer relations skills. He's very pro customer! Many sales reps that I have dealt with don't have a clue of just how valuable a customer is. The product itself is fine. However, it was abused during shipping, leaving dings on it. The shipping box arrived almost destroyed. The ball mount itself is good quality, heavy, and solid.

- C45338

The hitch was able to perform as I had intended it to. However instead of using it as a drop I am using it as a rise and it would have been better if I had a 10 inch rise. I am using a front hitch (which I also got from etrailer) to maneuver a trailer into a tight parking space.

Still great

Quality product bu found I didn’t need this much drop

- C45338

This is a great drop hitch for my lfted truck, very great experience dealing with Etrailer in all aspects of my order, will definitely order everything I can from them in the future.

- C45338

Heavy duty, great quality as described!

- C45338

It is exactly what I expected.

- C45338

Perfect fit exactly what I needed. I have a light duty adjustable hitch that I worried was inadequate. I purchase this for the rating and reassurance that I was safe towing my heavy trailer and tractor.

- C45338

Awesome product!

- C45338

This product works as described. I used it in the rise position with a 2 5/16 ball to pull a 40ft bumper pull RV that weighs about 8000lbs.

- C45338

As advertised. Nice unit

- C45338

Received my ball mount and everything was intact. Is just what I expected. Looks sturdy and well built.

Great. Even after I purchased a different truck, I was able to make it fit by minor adjustments to it. Customer service was very helpful picking the right tool for the job.

Worked really well - Jeep Grand Cherokee has a high back bumper - Kayak trailer is low to the ground and we like to pull it level.

Working well - use it most every weekend.

completely satisfied , good shipping, good products . I use the 2 inch hitch and 2 inch ball about every week on my jeep grand cherokee . I use the trailer dolly to park the utility trailer behind the using the trailer dolly I don't have to drive the jeep on the lawn. (sorry I don't have pictures to send.)

- C45338

Great product, fair price, excellent service and fast shipping. Great experience, thanks!

very well

Speedy delivery. Excellent quality.

- C45338

I love ordering from etrailer. Easy to find what I'm looking for and it gets here quick. Everything they carry is great quality from my experience so far. I needed yet another drop hitch for my truck this time for a 2 5/16' ball. Great price for something that is rated 10k pounds.

- C45338

Purchased a hitch and ball from eTrailer. The information and videos on the website were very useful. The products were shipped out the same day and everything was received promptly as advertised. Very satisfied.

- C45338

After a year the mount shows no wear at all I would recommend this product to any one needing a good hitch mount, with a large rise and drop.

- C45338

I have used etrailer for many products and goods. They have excellent products and information specific for your vehicle.

- C45338

This drop hitch is well made and has a nice protective finish. We just bought a much bigger truck and the drop will allow towing of my smaller trailer nice and level. The specified amount of drop is accurate.

- C45338

Works perfect to tow my jeep behind my motorhome. Thanks

- C45338

Enjoyed the way your web site setup which made it easy to select what I was looking for and check out. The hitch was just what I needed, thanks folks.

- C45338

Works as expected - made well. Amount of drop was just right to make my trailer level when towing.

- C45338

great product, looks great, problem is I ordered the wrong rise, I ordered 7 inch and actually need a 5 inch rise. should have ordered Curt Ball Mounts Code: C45336

- C45338

This drop hitch rated at 10,000 lbs is so much cheaper than anyone around me and the quality is excellent. I've used etrailer for several purchases over the years they always deliver. I'm always impressed with their selection and pricing. On this last order they upgraded my shipping and I received my order 4 days earlier than expected.

  • Hitch Pin Hole to Support Gusset Distance on Curt 10K Ball Mount 8-1/2 Inch Drop
    On Curt ball mount # C45338 it measures approximately 5 inches from the center of the pin hole to the support gusset. However, the welds could be slightly different from one to the next so on some it will be less and others it will be more but only by a fraction of an inch. I have linked a video review of this ball mount for you.

  • Ball Mount for Trailer Hitch Height of 12-1/2 inch and Coupler Height 19 Inches
    The two dimensions needed to be compared when picking out rise/drop ball mount is the top of the hitch opening down to the ground as well as the bottom of the coupler lip on the trailer down to the ground when the trailer is level. Since you measured from top of the coupler you'd need to remove right at 2 inches from 21 so you'd have from 12-1/2 inches to 19 inches which is 6-1/2 inches. So the closest you can get to that is 7 inches of rise like the part # C45338 which would work great.

  • What is the Ground Clearance for the Curt Hitch # C13397 for My 2021 Honda CR-V?
    The height from the ground to the bottom edge of the Curt Hitch # C13397 on your 2021 Honda CR-V is 11-1/4 inches. With this ground clearance height, I recommend using a drop hitch like the Curt Ball Mount for 2" Hitches - 7" Rise, 8-1/4" Drop - 9-3/8" Long # C45338. With this adapter, you will be able to have a higher ground clearance if you use a small utility trailer.

  • Hitch Extended to Keep Trailer From Hitting Flat Bed Truck While Turning
    Since flat beds are longer than regular truck beds situations like yours can occur more often than with a regular truck. Using a longer ball mount or a hitch extender is a viable option. Since the longest ball mount with an 8 inch drop is # C45338. It measures 9-3/8 inches from the center of the hitch pin hole to the center of the ball hole. If that is not enough length then an extender will need to be used. The use of an extender reduces the tongue weight capacity of the trailer hitch...

  • Ball Mount with 8 Inch Rise Needed To Tow Boat Trailer Level
    I recommend the Curt Ball Mount # C45338. This ball mount offers a 7 inch rise, which will put you within an inch of level. This ball mount will fit 2 inch hitch receivers and has a gross towing capacity of 10,000 pounds and a tongue weight capacity of 1,000 pounds. In order to have an 8 inch rise with a high enough towing capacity, you will want the Convert-a-Ball Adjustable-Height Ball Mount # TK5007. This adjustable ball mount has a maximum rise of 9 inches.

  • Recommended 2 Inch Hitch Ball with 10,000 lb Capacity for Curt Ball Mount
    There is a 2 inch hitch ball rated for 10,000 lbs that is compatible with the Curt Ball Mount # C45338. I recommend the 2" Hitch Ball # A-90 because it is rated for 10,000 lbs and has a shank that measures 1-1/4" diameter x 2-5/8 long so there will be minimal excess once the nut is tightened. I have added a link to a video review of this hitch ball for you to check out as well.

  • Ball Mount with 6 inch Drop and 1-7/8 inch Hitch Ball
    For a 6 inch drop ball mount that would fit the 2 inch hitch of your 2019 Subaru Ascent we have the Draw Tite part # 40346 and then for a 1-7/8 inch hitch ball you'd want the part # 19261 and you'd be set. The Curt ball mount does not have the smaller ball size available for it since the ball hole is larger.

  • Ball Mount Recommendation for 2 inch Hitch that Needs Rise of 6.75 Inches
    For the Curt hitch part # 13266 that fits your 2012 Volvo XC70 the ball mount you'd want would be the Curt # C45338 which has rise of 7 inches. With suspension sag from the tongue weight of the trailer this would put you right where you need to be for the trailer to sit level. I also attached a help article on determining the correct rise/drop ball mount for you to check out as well.

  • How to Determine the Amount of Drop Needed on Ball Mount for Towing Trailer
    When determining the amount of rise or drop you will need on the ball mount for your towing setup, you just need to take a couple simple measurements. The first, which you have already taken, is from the ground to the top of the trailer hitch receiver when your vehicle is parked and on level ground. The second is from the ground to the bottom of the trailer coupler when it is also parked on level ground. You did state you took a measurement when the trailer was attached to a different vehicle,...

  • Ball Mount to Use for 6 inch Drop When Using Curt Rockerball
    The place to measure on your trailer for picking out correct rise/drop is actually from the bottom of the coupler lip. So since you measured from the top of where the ball fits into the coupler you'd need to subtract about 2 inches from that so you'd have 17 inches. So difference between 23 inches and 17 inches is 6 inches which means you'd need a drop of inches. So since you have a Curt Rockerball that adds 2 inches you'd need a 8 inch drop then. So for that you'd want the part # C45338...

  • Can Curt Ball Mount Part # C45338 be Used with Tow Dolly
    Yes, if you had a tow dolly that attaches to a hitch ball the Curt ball mount part # C45338 that you referenced would work well with it. For hitch balls you'd want the part # A-90 for a 2 inch ball or part # C40036 for a 2-5/16 inch ball.

  • 12K-Rated 2-Inch Ball Mount with 8-Inches of Drop
    For a 2-inch ball mount rated for 12,000-lbs that has 8-inches of drop we offer two options you can see on the linked page. Part # 4283 from Draw-Tite provides 7-inches of rise or 8-inches of drop, as does Curt # C45448. Both take a hitch ball, sold separately, like 10K-rated # A-90. This is the highest-rated 2-inch ball we offer. We do not have a 12K ball mount with this rise/drop that comes with the hitch ball pre-mounted.

    Yes! The Curt Ball Mount # C45338, which has a 7 inch Rise and a 8-1/4 inch Drop, has a ball hole diameter of 1-1/4 inches and the ball hole platform is 3/4 inches thick. You will want to secure this to your trailer hitch receiver with a pin and clip # C21500. You can use either a hitch ball that has a 2 inch diameter # A-90 or a 2-5/16 inch diameter # 19286.

  • Can the Ark Articulating Coupler Be Used with an Adjustable Channel Mounting Ball Mount
    We haven't tested using an Ark Articulating Coupler # AR44FR with a Curt Adjustable ball mount like the # C45902 and I don't think this is going to work because of the limited clearance from the hitch ball to the channel. You'll instead want to use a ball mount with a drop like the # C45338 specifically for towing with the AR44FR, since it will allow the coupler to move freely. I've linked an article on how to properly measure for a drop/rise ball mount to this answer in case you're not...

  • Ball Mount to Clear Rear Bumper on 2013 Toyota Sienna and Provide Close to 7 Inch Rise
    Based on your measurements getting exactly what you need is a little tricky but I have some possible options for you. I can get you close to the rise you need by using ball mount # D-28, which has a 4 inch rise, with hi rise ball # C40034 or # C40032, both of these balls offer another 2 inches of height for a total rise of 6 inches. The tongue weight of the trailer will pull it down a little so at most you would be off level by 1 inch.

  • Gaining Rise With a Hitch Ball
    You can get get a hitch ball with a 1 inch diameter shank that will give you 2 inches of rise with a 2 inch ball # C40034, though that is going to limit your towing capacity to 6,000 lbs. If you needed to stick with a 10,000 lb towing capacity, then you would need a new ball mount, # C45338 for 8 inches of drop, # AMSC6 for 6 inches of drop or if four inches of drop was needed, # AMSC4. I have added links to video reviews of each of these ball mounts for you to take a look at.

  • Ballmount Rise/Drop Needed for Towing Rental Car Dolly with 2015 Dodge Charger
    The closer you can get the hitch ball height to the level height of the trailer (tow dolly in your case), the better. Towing the trailer nose up or down can cause trailer sway, which you'll want to avoid. For best results, you'll want to get the coupler and ball height within 1-1/2 to 2 inches, and it's better to have the coupler slightly lower than the trailer ball than vice versa. A ball mount with a 7-inch rise like # C45338 would put you right where you need to be, height wise. If...
