Video Transcript for Curt Chrome Hitch Bal Review

What's up everybody Adam here with etrailer. Today, we're gonna be taking a look at the Curt Trailer Ball. So this one's gonna be 2 5/16". So you want to make sure you match it up with your coupler. Typically on the top of the coupler, we're gonna have a couple numbers, and that'll kind of tell you that if it's an older coupler, you just want to make sure that it is the right size before you purchase. This one is gonna have a capacity of 10,000 pounds.

So you want to match it up with the right equipment. So make sure that the ball mount's gonna be at least 10,000 pounds. And of course, make sure that your vehicle and your hitch can handle that as well. Whenever you're picking a ball mount, you want to make sure that the diameter of the hole is gonna be 1 1/4" in diameter. I don't want anything bigger because there's gonna be too much slop.

And of course, anything smaller isn't gonna fit. So we want to make sure it's nice and tight. And that is the size we want to kind of go for. The shank is about 2 5/8" long so it's gonna work with ball mounts that have 1/2" to 1" thick. So this one right here is on the heavier side, but it's still within those bounds, so we're good to go.

It does have a chrome plating around the whole entire ball. If you want to put some grease on it, you can. That will kind of help limit the amount of wear you're gonna have, but it's inevitable, it's gonna happen. If you do want to upgrade, 'cause trailer balls are pretty much the same, you just need to get the right size and the right capacity. But if you we're to upgrade, you can get one that's made of stainless steel.

It's all machined out of one piece, that's gonna hold up against the elements a little bit better, but also there are some other ones as well that has had coatings on them and such. Chrome looks good now, but eventually it will wear away and not really look the best. So, just kind of take that into consideration, but that's pretty much with any ball. There isn't a whole lot to this, and that's pretty much it for our look at the Curt Trailer Hitch Ball..

The hitch and ball are perfect, as I needed a longer hitch to get past the bumper. Excellent product! When the package was delivered, there was a hole in the box and the actual hitch was missing.

Ball mount and trailer hitch ball were precisely as advertised. It is nice that I was able to find exactly what I needed to pull the 7,500 lb. (Gross Trailer Weight) utility trailer safely. The Big-Box stores just did not have the selection!

Ask the Experts about this CURT Trailer Hitch Ball



  • What is the Torque Spec for a Nut on a 1-7/8 Inch Hitch Ball
    The torque value for your 1-7/8 inch ball is going to depend on the diameter of the shank. Draw-Tite lists the following torque specs: "During hitch ball installation, torque all 3/4" shank diameter balls to 160 ft. lbs., and 1" shank diameter balls to 250 ft. lbs., and 1-1/4" shank diameter balls to 450 ft. lbs."

  • What Torque Rating Should the Trailer Hitch Ball # A-6 be Tightened To
    I spoke with my contact at CURT and he informed me that this 2-5/16 inch Trailer Hitch Ball # A-6 will need to be torqued to 450 ft/lbs. I attached FAQ on hitch balls for you to check out also.

  • Hitch Installation Bolt Torque Ratings on Hitch for 2005 Chevy Express
    We currently offer 10 different receiver hitches for the 2005 Chevy Express, with towing capacities ranging from 3500 to 12,000 lbs. The torque rating of the installation bolts will depend on the particular hitch being installed, the rating will vary according to the weight capacity of the hitch.

  • Trailer Hitch Ball Wrench Size and Torque Rating for 1-1/4 Inch Hitch Ball Shank Size
    You can have a 2-5/16 inch hitch ball on either a 1 inch or 1-1/4 inch shank. The nut on a hitch ball with a 1-1/4 inch shank takes a wrench with a 1-7/8 inch socket. A hitch ball with a 1 inch shank will take a wrench with a 1-1/2 inch socket. You will need to torque all hitch balls with a 1-1/4 inch shank, like 2-51/6 inch hitch ball # A-6, down to 450 ft/lbs. I am including a link to some helpful trailer hitch ball information, if needed.

  • Torque Specifications For A 2 Tow Ball Nut Towing A 700lb Drift Boat
    The 2" Hitch Ball like the # A-90 requires a foot pound torque of 450 but I would really need to know your specific ball to tell you the torque rating. An impact wrench is the preferred installation method but if you don't have access to that, you can also torque down with a 1-7/8" wrench or socket. After inserting the ball mount in your receiver sideways you can torque it down as tight as you possibly can. Included is a video resource for this hitch ball example. I hope you have a...

  • How to Choose the Correct Replacement Hitch Ball
    In order to choose the correct replacement hitch ball you would need to measure the diameter of the shank, length of the shank, and diameter of the ball. The diameter of the ball should be stamped into the head but the other two will more than likely need to be physically measured. For example, the part # 63845 has a 2-1/8" long x 1" diameter shank with a 2" ball. Once you find out the above info you can then use our selection which I have attached for you to find the correct one for...

  • Comparing Smartphone and Display Version of the Tireminder TPMS Systems
    I'd go with the smartphone version of the Tireminder TPMS part # TPMS-APP-6 over the kit that comes with a display part # TM-A1A-6. Since it connects to your phone that's one less thing to remember on trips and it's one less thing you'd have to install and keep track of.

  • TireMinder Tire Pressure Monitoring System for Multiple Trailers
    I spoke with my contact regarding your existing solar powered TireMinder Tire Pressure Monitoring System. We do not currently have this particular kit but she said that it is really only designed to be used with one trailer. The transmitters with that system are specific to the monitor so additional transmitters could only be added if the ones you currently have on your camping trailer are "deleted" from the system.. This means you would need to go through the process of deleting and relearning...

    With there being 3 standard size balls used to tow a trailer, you can simply measure for 2 of them Those being a 2 inch coupler that attaches to something like the Curt 2" Hitch Ball - 1-1/4" Diameter x 2-5/8" Long Shank # A-90, or a 2-5/16 inch one that will attach to the 2-5/16" Hitch Ball - 1-1/4" Diameter x 2-5/8" Long Shank # A-6. The one that throws a wrench in the this is the 1-7/8 inch ball, like the Curt # A-80. With it being so close to 2 inches, it will definitely make differentiating...

  • Recommended Ball Mount for 8 Inch Drop and 7,500 to 10,000 Capacity
    The Draw-Tite Ball Mount for 2" Hitch - 7" Rise, 8" Drop - 9-1/2" Long - 12,000 lbs # 4283 is the closest we have to what you are looking for in a fixed mount. It has an 8 inch drop, 12K capacity, 1-1/4 inch hitch ball hole diameter, and 7/8 inch thick mount. The smaller diameter holes and thinner mount will leave you with only a 5K capacity. For a 2 inch ball, I recommend # A-90 and for a 2-5/16 inch ball # A-6. Let me know if you have questions or need a recommendation for that 5K...

  • Will Curt Hitch Ball # A-6 Work with a Blue Ox SwayPro Weight Distribution System # BXW0751
    The hitch balls we recommend for this Blue Ox SwayPro Weight Distribution System, part # BXW0751, have a shank length of either 2-3/4-inches (part # 19286 with a 2-5/16-inch ball size) or 2-5/8-inch (part # A-90, with a 2-inch ball size). The ball you ordered, part # A-6, also has a 2-5/8-inch long shank, so it should work with your Blue Ox SwayPro.

  • Can TireMinder A1A Tire Pressure Monitoring System TM-A1A-6 Read Pressure in Spare Tire
    The TireMinder RV Tire Pressure Monitoring System # TM-A1A-6 will still be able to accurately read and report the PSI pressure in your RV's spare tire, even though the tire is mounted on your spare tire carrier and is not rotating. I confirmed this with my contact at Minder Research, maker of the TireMinder system # TM-A1A-6.

  • Can TireMinder TPMS System Be Used on Inner Tire Valve Extensions
    I reached out to my contact at TireMinder and she said there aren't any issues using their TPMS systems like the part # TM-A1A-6 you were looking at with valve extensions, as long as the extensions are steel. The added weight of the sensors won't cause problems with them potentially snapping off during travel. They will work really nicely for your RV's inner tires. I have attached a short video review and the written install manual below that you can check out as well.

  • Best Way to Reduce Suspension Sag When Towing a Trailer
    We have the perfect product for you, but it's not a suspension enhancement system as they are more ideal for vehicles that are carrying weight in the cargo area of the vehicle. For a towing situation a weight distribution system would be much better as it actually distributes the tongue weight of the trailer up to the front axle of the tow vehicle which will help with braking and handling. The best way to pick out a weight distribution system is to base it off of the loaded tongue weight...

  • Is a Weight Distribution System or Sway Control Needed for 3,500lb Trailer with Chevy Silverado 3500
    Considering the towing capacity of your Chevrolet Silverado 3500 and the relatively light 3,500 pound Casita Trailer, you most likely will not need a weight distribution system or sway control. I recommend simply going on a few test drives with your trailer to see how everything handles. If after a few trips, you feel like the control and stability of the ride can be improved upon, a weight distribution system might be a good idea. If you do end up looking for a weight distribution system,...

  • Will Curt Hitch Ball # A-6 Work on Reese Steadi-Flex Weight Distribution System RP66559
    Yes, the Reese Steadi-Flex weight distribution system part # RP66559 that you referenced takes a hitch ball with a 1-1/4 inch diameter shank that is 2-5/8 inches long just like the part # A-6 so it would work well. Also this has the same 10k capacity as the Steadi-Flex.

    The Curt TruTrack Weight Distribution System w/ Sway Control - Trunnion - 8,000 lbs GTW, 800 lbs TW # C17499 will allow a rise of up to 6 inches so it will work well for you. The shank will need to be inverted for the rise position and you will put the hardware in the 3rd and 5th holes from the top when inverted. You will need to torque the hitch ball and the shank to the manufacturer specs, so if you don't have the ability to do that on your own, I recommend going to a local mechanic...

  • Recommended Weight Distribution & Sway Control for Small Hybrid Camper
    Weight distribution fit is determined by the total tongue weight of the trailer. This total tongue weight includes the loaded tongue weight of the trailer (not the dry weight) as well as any cargo weight behind the rear axle of your towing vehicle. In your case this won't be much because you have a jeep without much cargo space. A system rated too high can create a rigid ride, so you want your total tongue weight to fall in the middle range of your weight distribution system's total...

Its 200-600 pound tongue weight capacity will work perfectly for the total tongue weight range you are looking at with this trailer and your Grand Cherokee.

It has a maximum tongue weight capacity of 1,000 pounds. The shank is included and it's adjustable to provide a max 7" drop (or a 10-1/2" rise).
