Video Transcript for Curt Ball Mounts - Adjustable Ball Mount - C45901 Review

Speaker 1: Today we're going to take a look at the Curt Channel Style Adjustable Ball Mount, has a 6,000 pound weight capacity. Now this is designed to mount on trailer hitches that have a two inch by two inch receiver tube opening. You notice this is an adjustable channel mount, which will allow for precise trailer leveling. There's six rows of holes here and each one is one inch increment between the rows, so you can move it up wherever you need it.It is equipped with a one inch diameter hole to accept a trailer ball. It has a shank diameter with one inch right here on the mount. Now this shank can also be flipped for maximum rise and a maximum drop.

Right now we have it in the max position, so here's the maximum drop. That would be measured from the top of the shank, to the top of the ball platform. You could put a ruler on that, maximum drop would be six and three quarter inches. If you turned it around, put it in the rise position, and measure top of the shank, top of the ball mount, you'd be measuring maximum rise of five and a quarter inches.Does offer two hitch pinholes, right here on the side. It'll provide either 11 inch or 12 inch shank length, and that measurement is from the center of the ball hold to the center of the hitch pinhole, you can see 11 inches to the first hole, and then 12 inches to the back hole.

Does also offer right down here if you can see, there's a rubber dampener, that you can move from either there or move it up. But that dampener's there to eliminate possible rattle between this channel mount and the ball mount platform when it's all put together.Now it is protected by a nice highly durable carbide powder coat finish. The pins and clips you can see for the channel mount are all included. And it also includes the hitch pin and clip to hold this mount to the hitch. Weight capacity again on this is 6,000 pounds.

Ton weight capacity is 600 pounds.That should do it for the review on the Curt Channel Style Adjustable Ball Mount with a 6,000 pound weight capacity.

Curt Channel Style Adjustable Ballmount - 5-1/4" Rise, 6-3/4" Drop - 6,000 lbs - C45901

Average Customer Rating:  4.9 out of 5 stars   (630 Customer Reviews)


by:

New GMC AT4 required a new ball mount and this one fit all the requirements for the truck and new multi-pro tailgate. With the AT4, I needed more drop and a longer shank (12" hole) for the tailgate to not hit my trailer jack stand; plus, the multiple drop adjustments will make changing trailers a snap. Great product from Curt and great service from etrailer (as usual).


Comments
Wow, this puppy works like a champ after one year of use. I pulled my trailer and Ranger to 26 NSCA tournaments with no issues and smooth, noiseless travel on these long hauls.

by:

Perfect drop hitch. Good brand name, good capacity, all around perfect



by:

This is a great ball mount. Fits the Class III hitch on my Explorer perfectly. Works well with my locking anti-rattle pin. However, there is a little noise from the dual pins used for the adjustment. I called etrailer’s customer service to inquire about remedies for this and was told that there is an Allen key adjustment that needs to be tightened to reduce the noise. I have yet to tighten it but other than that, the ball mount has done a great job.



by:

I love the way it can adjust to the trailer I am pulling. It handles the trailer and load great. It's heavy duty.



by:

Heavy adjustable hitch. Works well. Easy to adjust.



by:

quality product for a reasonable price. etrailer always delivers with good prices and turn around time.



by:

Nice hitch. Easy to adjust and level the truck/trailer. Free shipping and arrived a day early!



by:

Love it, it made it to the Canada border region, Glacier Nat'l Park,and many many miles since!

This product gives me several options for adjusting the trailer tongue height.
It does the job I need it to do.


Comments
Continues to perform well, absolutely no complaints!
Brent - 05/27/2021

by:

Nice welds, more than heavy enough for my trailer. Quick adjustment and I like that the length from coupler pin to the ball is a little bit longer than what I had so the trailer is not as close to the bumper on tight turns. Good product



by:

I helped a fellow co worker on a good budget hitch for his new truck to tow his rpod. I pushed him to an adjustable hitch for the adjustable feature. I have more hitches than you can imagine lol even with having an my main as a adjustable hitch. If you’re on a budget and really only use one size ball this is a great hitch and does not rattle.



by:

Everything arrived on time and without damage. Installation took minutes thanks to the online video instructions, my wife and I are looking forward to many adventures this summer with our new camper. Many thanks to the folks at etrailer who made the hitch, wiring and brake installation painless on our tow vehicle.



by:

good quality



by:

seems too be built very well. it was a little sloppy in the receiver. worse than my old one but I think over all it will be a great hitch for what I need.



by:

They should work great for my new boat!



by:

Works great for leveling trailers. Very easy to adjusting



by:

I use it 5 days a week. Good tow hitch



by:

I am very impressed with the quality of this product. I wanted the ability to adjust the height because I pull farm equipment between farms with my pickup I also wanted the heavy 6000 lb rating for safety. I have showed it to several other people and they are all impressed. I look forward to using it.

Ask the Experts about this CURT Trailer Hitch Ball Mount



  • Does Shank Length of Curt Adjustable Ball Mount # C45901 Affect Capacity of Hitch
    An 11 inch long ball mount is on the longer side but not long enough that it would it diminish the towing capacity of your Toyota Highlander. If were to go much beyond 11 inches I would begin to worry that maybe the leverage would be too much but for your situation I would not think twice about it being totally.

  • How To Find the Correct Ball Mount for a 2021 Toyota RAV4
    In order to find the correct ball mount rise/drop for a 2021 Toyota RAV4 you'll need to measure from the ground to the top inside edge of the receiver on the vehicle and then from the ground to the bottom of the coupler on the trailer while level. The differences between the two measurements will be your rise/drop. The etrailer Ball Mount Kit for 2" Hitches part # 989900 for example has multiple options for different trailers.

  • Adjustable Ball Mount for Ford Expedition Towing Boat Trailer
    If you went with an adjustable ball mount like the part # AM3410 you'd have ability to select the correct rise drop for your trailer to tow it level or if you determine the rise/drop you need I can recommend you a fixed hitch instead. I attached a help article on determining the rise/drop you would need. The part # AM3410 has the ball size you need, the weight capacity you need, and also can do up to 5-1/2 inches of drop.

  • Is 2" Curt Rocker Ball Compatible With Curt Channel Style Adjustable Ball Mount C45901
    Since your trailer has a 2" coupler you will need to use the Curt RockerBall Shock Absorbing 2" Hitch Ball - 1" Diameter Shank - Chrome - 7.5K # C40047. The # C40047 will work perfectly on the Curt Channel Style Adjustable Ballmount - 5-1/4" Rise, 6-3/4" Drop - 6,000 lbs # C45901. While the # C40047 has a 7500lb towing capacity, since the # C45901 has a maximum towing capacity of 6000lbs you will be limited to 6000lbs which is plenty since you are only planning on towing 3500-4000lbs.

  • Replacement For Platform For Curt Ball Mount C45901

And while Curt does not offer this separately, we do have an option for you that will work, which is a dual-sided hitch ball that fits the platform; you will also need the pins to mount it: - Replacement 2" and 2-5/16" Dual-Sided Hitch Ball for Curt 2" Adjustable Ball Mount # C45912 - Replacement Pins and Clips # C45925

  • Solution for Ball Mount to Move Trailer up Steep Driveway
    The best solution would for a ball mount to help you move your trailer up a steel driveway would be one with a good amount of rise. An adjustable ball mount would be the best for this, something like the Curt Channel Style Adjustable Ball Mount - 5-1/4" Rise, 6-3/4" Drop # C45901. I'm not sure what rise or drop you use now, but this would give you some additional rise and allow you to use the rise or drop you need for normal towing circumstances.

  • Recommended Ball Mount To Replace Curt C45901 With Missing Parts
    I reached out to my contact at Curt and while I have a complete replacement option for you, the ball mount section of the # C45901 is not available separately. Since there is no other ball mount option of the same style that will fit your shank, you will need to purchase another # C45901. In addition you will need a hitch ball with a 1" shank, the 1-7/8" # C40002, 2" # 40083, or 2-5/16" # C40005. I included a video of the # C45901 for you to take a look at.

    The Brophy Ball Mount # EA60 only has a 4-3/4" distance from the end of the shank to the center of the hitch pin hole so it will most likely contact the bumper of your 2021 Mazda CX-9. Instead I recommend the Curt Channel Style Adjustable Ballmount # C45901 which is going to give you approximately 6" in length from the end of the shank to the center of the rear hitch pin hole as well as the 5" rise you were needing.
