Video Transcript for Curt Hitch Ball - Trailer Hitch Ball - C40007 Review

Today we're going to be taking a look at part number C40007. This is the Curt Chrome Hitch Ball with 2 5/16ths inch diameter, steel construction with a chrome finish, so it's going to offer protection from rust and corrosion. It's also going to feature the wrench flats here on the side of the platform. It's going to allow you to easily get your wrench on there and tighten to the mount and you can easily get it torqued to specifications listed by the manufacturer. The torque rating for this particular mount is indicated in the instructional tag here on the backside. It says that it needs to be tightened to 250 foot pounds of torque. The capacity on the ball is going to be 10,000 pounds.

The shank diameter, this portion here, is going to measure 1 inch. The shank length, measuring from the bottom of that platform to the end of the threaded portion, that's going to give us a measurement of 2 1/4 of an inch. It does include the lock washer, as well as the nut. That's going to do it for today's review of part number C40007. This is the Curt 2 5/16th inch Chrome Hitch Ball, rated at 10,000 pounds. .

I picked 5 to 7 day shipping (foolish) and was pleased when my order was upgraded to 3 to 5 day express shipping FREE. Everything arrived 3 days before our trip and worked perfectly.

    Brophy 2 inch hitch ball # CB26C is made in the USA. It is rated for 7,500 pounds and has a shank length of 2-1/4 inches and shank diameter of 1-1/4 inches. Convert-A-Ball interchangeable ball set # 901b has a 2 inch ball as part of the set. It is made in the USA and is rated up to 10,000 pounds. The shank diameter is 1 inch and the length is 2-1/2 inches. Set # 903b has the same specs except it is stainless steel and the shank length is 2-1/4 inches. The Convert-A-Ball sets will all...

  • How Tight Should Nut be On Curt Hitch Ball # C40007
    Looks like you have the wrong tag on your hitch ball part # C40007. The tag that it should have came with is supposed to read 250 ft lbs. If you watch the review video I attached for this ball you'll see our reviewer reads from the tag that it requires 250 ft lbs.

  • Is 2 Inch Hitch Ball Okay to Use With 2-5/16 Inch Coupler
    While I can sympathize with your issue, it is not safe to tow a trailer if you only have a 2" hitch ball and your trailer coupler is designed for a 2-5/16" hitch ball, even for a short distance; the insecure connection between hitch ball and coupler would pose a danger to others because of the risk of the trailer becoming uncoupled from the tow vehicle. The correct 2-5/16" hitch ball will depend on the shank diameter you need as well as capacity. Your ball mount will have a hole where...

  • Can My 2007 Honda Odyssey Tow a 1500 Lb Empty Trailer With a 2-5/16" Ball?
    Your 2007 Honda Odyssey has a towing capacity of 3500 lb, so you should have no issues towing a 1500 lb empty trailer with a standard 2-5/16" ball like # C40007.

  • Trailer Hitch Ball Mount With Longer Shaft and 2-5/16 Inch Hitch Ball
    We can get you a ball mount with a longer shaft to help keep your trailer safe. Without knowing the rise or drop you need, or the weight capacity, I can only offer a couple of general recommendations for ball mounts with long shafts. Since you have a trailer that utilizes a 2-5/16" hitch ball I assume it is on the heavier side so the best options are: - 13-1/4" Long Shaft: Brophy Ball Mount for 2" Hitches - 3/4" Rise, 2" Drop - 10,000 lb Capacity # BM20 and 2-5/16" Hitch Ball # C40007 -...

  • How to Find a Ball Mount with the Right Rise or Drop to Tow a Trailer Level with a Ford F-150
    Yes, it is likely supposed to be 2-5/16 since there isn't a 2-5/6 option. In order to choose the best ball mount for your new Ford F-150 and motorcycle trailer you will need to do just a little measuring. You want to be able to tow the trailer level so you have to measure for the rise or drop needed to do so. Measuring is easy. Park the truck and the trailer on level ground. Measure from the ground up to the top of the trailer hitch receiver opening. Then use the trailer jack to make...

  • Will the Curt Chrome Hitch Ball # C40007 Fit a 3/8 Inch to 7/8 Inch Thick Ball Mount Platform
    Yes, the Curt Chrome Hitch Ball, # C40007, will just barely fit on a ball mount platform that is 7/8 inch thick. If your ball mount is 7/8 inch thick, you will have 2 or 3 threads showing past the nut, but the nut would fully engage the threads on the hitch ball shank.

  • Hitch Ball Recommendation Made in America
    I believe I have something that will work for you, but the Curt Hitch Ball # C40007 that you referenced is not made in the USA, it is made in China. You might be interested in a Convert-A-Ball Interchangeable Ball Set # 904B. This product is made in the USA and comes with an interchangeable hitch ball that will give you the option to easily change between a 2 inch and a 2-5/16 inch ball.

  • Does The Curt Rebellion XD Shock Absorbing Adjustable Ball Mount Require A Minimum Tongue Weight
    There is not an exact set minimum tongue weight for the Curt Rebellion XD Shock Absorbing Adjustable Ball Mount w/ 2" part # C45949-22516 however it is not going to be very effective on a light weight trailer. We have asked Curt before about lightweight trailers between 2k and 5k and they do agree there won't be enough tongue weight to compress the cushioned isolator so you would essentially be paying for something you can't use. I recommend to use the Convert-A-Ball Dual-Cushioned part...

  • Can I Extend My Hitch Without Using TorkLift Hitch and SuperTruss Extension
    The only other extension option we carry besides the Torklift SuperTruss extender that does not cut your tongue weight in half is an extra long ball mount. Traditional extensions such as part # C45796 cut the tongue weight capacity of the hitch on the truck in half because it creates extra leverage and movement in your towing setup. The only extra long ball mount we offer that is long enough for your setup is the Hidden Hitch ball mount part # 80232 at 15-3/4 inches long. That length...

  • Recommended Extended Ball Mount or Hitch Extender for Towing Boat Trailer
    For your 2018 Tahoe and boat trailer needing a longer extension between them I recommend the Hidden Hitch Ball Mount - 3/4" Rise, 2" Drop - 15-3/4" Long - 6,000 lbs # 80232. Having a longer ball mount like this will not reduce the capacity of your hitch at all. This will give you a length of 15-3/4 inches from the center of the ball to the hitch pin hole. For a compatible hitch ball the shank needs to be 1 inch diameter for this mount. I recommend the 2 inch ball # 40038 or 2-5/16...

Then measure from the ground to the underside of the trailer's coupler with it level as well. The difference between the two tells you how much of a rise (the trailer is higher than the vehicle) or a drop (the vehicle is higher than the trailer)...

  • Determining Correct Ball Mount for 2007 Honda Odyssey to Tow Pop Up Camper
    The way to determine the correct amount of rise (or drop) needed to tow a trailer level there are a couple of measurements needed. First you would measure from the ground up to the top of the receiver opening on the trailer hitch. Then, with the trailer level, measure from the ground to the bottom of the coupler. If the trailer is higher the difference is the amount of rise you will need. And if the vehicle is higher the difference is the amount of drop you would need. On the 2007 Honda...

The Curt hitch # 14001 is also a fit for '97 F-250 HD's that have step bumpers such as the Westin (I've attached a photo which shows the hitch on a truck with a step bumper) and will work for you so long as you have the larger 37-3/4" frame and not a 34" frame.

    To determine the amount of drop you need in a ball mount you need to have your trailer and tow vehicle on level ground and measure from the ground to the bottom of your coupler, and from the ground to the inside of the top of your hitch receiver. I've attached a couple of pictures to help show this. Since you measured from the bottom of each you're likely going to need more than 10 inches drop. You'll likely need around 12 inches or so like the Convert-A-Ball, part # AMSC12. If you...

  • Recommended Weight Distribution System for 300 Lbs Total Tongue Weight
    In order to choose the correct weight distribution system, you will need to find the total tongue weight (TTW) of your towing setup by adding the tongue weight (TW) of both your loaded ready to tow trailer and any cargo stored behind the rear axle of the tow vehicle. An easy way to find this would involve using a tongue weight scale like the Sherline Trailer Tongue Weight Scale part # 5780. When choosing a weight distribution system, you will want your TTW to fall in the middle of the...

But to choose one that has the right rise or drop to tow a trailer level there are just 2 measurements needed. Once that is figured out you can select a ball mount and then a compatible ball. You will need to have the vehicle and trailer on level surfaces to measure. Use the trailer's jack to make sure the trailer is level before measuring. Measure from...

    The correct hitch for your truck will depend on what capacity you were needing. For instance, if you'll be towing trailers weighing less than 6000 lbs, a Class III hitch like the # 75662 would be ideal. The hitch would bolt to the existing crossmember and the rear bumper. For a heaver trailer (assuming your truck has the necessary capacity), a Class IV hitch like # 14361 would work well. The Curt # C15409 you referenced is only a fit for trucks already equipped with the factory hitch. You...
