great price, and easy installation 1/2 hr. and i was done




by:

Looks great




by:

Good quality part at a good price. One suggestion; when customers order a mount and a ball, offer a installation service. Not everyone has the proper tools to torque something this big.


Comments
As expected, this Curt product delivers without any doubt. Has been in use for thousands of miles without any concerns.

This looks to be very well made product. I ordered a stainless hitch ball, and it has a 1" shank. I forgot to order a 1.25" to 1" reducer, since the hole in this is 1.25". Other than that, I'm hoping it lasts as long as the other Curt products.

I have just started using this company and this is only my second order. I do have to say that their service is phenomenal, no problems and great tracking on their part. I have to call them about leaf spring bushings that’s next. RV

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

  • Is There a 2 Inch Ball Mount with 1 Inch Drop
    I do have an option for you but we don't have any 2" ball mounts with a 1" drop exactly, that said the vehicle will likely sag a bit once coupled to the trailer so a 2" drop ball mount should work great to keep the trailer level. I recommend the Curt Ball Mount for 2" Hitches part # C45310 which is rated for 10,000 lbs.

  • Recommended Ball Mount To Use A 2-5/16" Hitch Ball
    I have another option for you, but all of our 2-5/16" hitch balls have at least a 1" shank diameter. Instead I recommend replacing your ball mount to accept a hitch ball with a larger shank like the Curt Ball Mount for 2" Hitches # C45310 which uses hitch balls with a 1-1/4" shank. This would allow you to use the Curt 2-5/16" Hitch Ball # C40030. I included videos to each of the products mentioned for you to take a look at.

  • Fixed Ball Mount With 1" Rise to Replace Ball Mount With 3/4" Rise
    I recommend to use the Curt Ball Mount for 2" Hitches part # C45310 which has a 1" rise and 2" drop. It measures 9-3/8" Long with a 10,000 lb capacity. I have attached a video for your reference. The ball hole diameter of this ball mount is 1-1/4" so you will need a new hitch ball. I recommend 2" Hitch Ball part # A-90.

  • Ball Mount Recommendation for 2015 Chevy Traverse with 2 inch Trailer Hitch
    The closest drop we have to a 3 inch drop ball mount for a 2 inch hitch is going to be a 2 inch drop. Which when you factory in a bit of squat from the rear suspension being loaded that should put you right where you'd need to be. The Curt ball mount part # C45310 would work well. The pin hole diameter is 5/8 inch which would be what your hitch has. 1/2 inch pin diameters would only be seen on 1-1/4 inch hitches. For a 2 inch ball you'd then want the part # A-90.

  • Ball Mount for 2 inch Hitch that has 2 inch Drop and 15k Total Weight Capacity
    Ball mounts with 1 inch diameter ball holes will have lower capacities like the Draw Tite part # 2923 which has a 1 inch ball hole size but only has a capacity of 7,500 lb. Only similar ball mount we have is the Curt Heavy Duty ball mount part # C45331 which as the same 2 inch drop like you need and a capacity of 15,000 lbs. It comes with a hitch ball mounted to it already which measures 2-5/16 inch. This would be your best option.

  • Is the Curt Ball Mount Compatible with the Curt A-90 Ball?
    Yes, the Curt item # A-90 hitch ball fits the Curt Ball Mount for 2" Hitches item # C45310. I recommend the Curt Towing Starter Kit for 2" Hitches - 2" Ball - 3/4" Rise, 2" Drop - 7.5K item # C45534. This will give you both the ball mount and the ball as well as a lock for your hitch mount.

  • Trailer Hitch and Ball Mount for 2007 Honda CR-V
    I can help you figure out exactly what you will need on your 2007 Honda CR-V to get your daughter home. First, Curt hitch # 13555 is a fit for your 2007 Honda CR-V and would be a good choice. This is a no-drill install that should be straightforward; I've added a link to a video of this hitch being installed on a '07 CR-V as well as the installation instructions for you to check out which should help determine if it's something you feel comfortable doing.

  • How To Determine Correct Ball Mount For 2016 Subaru Outback Wagon Towing Trailer
    I would be happy to help! To determine the correct ball mount and hitch ball for you, you will need to know the hitch height of the Curt Trailer Hitch # C13206 once installed on your 2016 Subaru Outback Wagon, and then the coupler height of your specific trailer. For the hitch height, we have installed this hitch on a 2016 Subaru Outback Wagon like yours and have found that it has a hitch height of 15-1/4". Now for coupler height you will want to call the trailer manufacturer and ask,...

  • Will the Curt RockerBall Shock Absorbing Hitch Ball Work With a Weight Distribution System
    The Curt RockerBall Shock Absorbing 2" Hitch Ball part # C40047 will not work with a weight distribution system because the flange that gets wedged between the platform and base that stops the unit from rotating will not fit over the shank on a weight distribution system. Therefore, the Curt RockerBall must be used with a standard ball mount like the Curt Ball Mount for 2" Hitches part # C45310. If you are looking to add a shock absorbing feature to your weight distribution system you'll...

  • Compatibility of Curt Ball Mount # C45310 with Curt Class III Hitch on 2005 Suzuki Grand Vitara
    The Curt Ball Mount # C45310 referenced in your question is indeed compatible and will work nicely with your Curt Trailer Hitch Receiver # C13517. This particular Class III hitch is also confirmed to fit your 2005 Suzuki Grand Vitara. The 2 Inch Hitch Ball # A-90 that you also mentioned features a 1-1/4 inch diameter shank so it will work perfectly with the ball mount. Since it sounds like you will be doing some towing, I recommend the Tekonsha T-One Vehicle Wiring Harness # 118372 if...

  • What is the Wall Thickness of the Curt Class III Ball Mount Part # C45036
    I spoke with my contact at Curt who informed me that the wall thickness of the Curt Class III Ball Mount part # C45036 is about 3/16" or .188" thick. In order to receive a ball mount with a wall thickness of 1/4" or .250 you would need to go up to a Class IV like the Curt Ball Mount for 2" Hitches part # C45310. This ball mount does not come with a hitch ball or hitch pin/clip like the above ball mount does but you can add them using part # A-90 and part # C21500. I have attached a review...

  • Is There A 2 Inch Trailer Hitch Ball Made In the USA
    The 2" Hitch Ball part # EH68C-C is made overseas but we do have a made in the USA hitch ball option for you, the Convert-A-Ball Interchangeable Ball Set part # 904B which gives you both 2" and 2-5/16" options. The majority of the trailer hitch balls are all made overseas. In regards to the Extra Long Ball Mount part # D-26, this does indeed have a reduced capacity due to the extended length but not by much. For reference, the Ball Mount part # C45310 is essentially a shorter version...

  • Can 18 Inch Hitch Extension be Used With 2 Inch Drop Ball Mount
    Yes, your 2000 Ford F-350 can use a ball mount with a 2 inch drop like # C45310 with and 18 inch extension, either the Reese Hitch Extender # RP11004 you mentioned or the Curt Extender # C45796. Keep in mind an extender will reduce the capacity of your trailer hitch, the Reese by 35 percent and the Curt by 50 percent. The extensions will also need a pin and clip or hitch lock to secure to your Ford's hitch, the Pin and Clip # C21510 or Hitch Lock # e98880.

  • Hitch Reducer Sleeve to Allow Use of 2-Inch Hitch Accessories in 2-1/2-Inch Hitch Opening
    Higher-capacity pickups like a Ram 3500, Silverado 3500 or Ford F-350 often have 2-1/2-inch hitches available. For the 2007 Dodge Ram 3500 we offer Draw-Tite 2-1/2-inch hitch # DT45509. If you have a 2-1/2-inch hitch and wish to use 2-inch hitch-mount accessory items such as a ball mount like # C45310 or cargo carrier like # C18151 all you need is a hitch reducer sleeve to drop the size of the hitch opening down to 2-inches. We have many such items shown on the linked page, including Curt...

  • Trailer Hitch, 7-Way, and Brake Controller Recommendation for 2022 Subaru Outback
    The hitch I would recommend for your 2022 Subaru Outback Wagon would be the Curt Class III part # C67JR as it is mostly hidden since only the hitch opening hangs below the rear bumper. This also gives it the best ground clearance. When we installed it on a similar 2022 Outback we found that it measured 16 inches from the top of the hitch opening down to the ground so you'd want a ball mount with a drop near zero like the Curt # C45310. For trailer wiring you will need to start with a 4-way...

The Curt # C13417 has a 6000 lb towing/900 lb tongue weight capacity, the Draw-Tite # DT73GR has a 8000 lb towing/1200 lb tongue weight capacity, and the etrailer # e63ZR has a 6000 lb towing/900 pound tongue weight.
