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..

It's a good product, very fair pricing and very quick shipping. Thank you for upholding honest business practices oh, you are my go-to source for trailer Parts and Equipment


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. I sent an email to them and the shipped a new one the very next day! No questions! This type of customer service is rare these days and they have won my loyalty. Great folks over there!


It’s a trailer ball and is round
fast shipping from etrailer


I always receive the best customer service from etrailer.You set the standard!


The products were perfect for my use. I can now drop my tailgate while the trailer is hooked up. However, more importantly the service was excellent. I recieved the order earlier than expected thanks to a free shipping upgrade. I will not buy my towing and trailer needs anywhere else.


Quality product, would recommend!


It's nice and chrome. Works well.


Awesome help in determining what I needed… shipping was super quick!!


This was my 1st purchase from e-trailer & I was very happy with the product & service. Very well made. High quality. Just as described. Fast shipping.


All is well thank you

Works great thanks again
Gus C - 08/02/2021


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!


The Hitch work as it was advertised, Loved it. Would not pull my cargo trailer without it. Have bought several item from etrailer in the past, always good products and good service. Always the first place I check before buying anything I need for my trailers.


Quality products and fast shipping.


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.


my another etrailer hitch purchase and another 5 star for their service/product and fast shipping


Shank is perfect length for a weight distribution hitch


Installed and works great. The nut was larger than my long hitch wrench could handle, but I came up with an alternative method to tighten the nut.


etrailer has what I need. Email updates on order status and the product was right on. Great quality and service. God bless the USA.


Pretty simple piece. It is what it is. High quality 2 5/16" ball with 1 1/4" shaft.


Perfect for what I needed


High quality.


I just wanted to tell you how much I appreciate your quick response to orders. Shipping orders right away, combined with your good prices, makes yours the company to go to for trailer-related purchases. Thanks!


Great customer communication, great service. The product was exactly what I ordered and a much better price then anything else I could find. Thanks for the communication and service


Hitch was exactly as depicted, Good value for the money. Shipped promptly, considering the holiday. Would buy from them again.


Works great no issues!

  • 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."

    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...

  • 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,...

    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).
