Video Transcript for Complete Breakdown of the Curt Lunette Ring

Hi, everybody, Andy here with etrailer.com, and today we're gonna take a look at this CURT stud-mount lunette ring. Now, if you are looking for a three-inch diameter, stud-mounted lunette ring that is designed to rotate on your trailer during heavy-duty towing over rough and uneven ground, this ring would be worthy of your consideration. This is a single-stud mount that is designed to let the ring rotate while you tow. And it's going to be ideal for heavy-duty towing, off-road towing applications. And it's going to eliminate the need for a swiveling pintle hook on your tow vehicle. Now, this is constructed from a strong forged steel with a weight capacity of 45,000 pounds, but you never want to exceed the lowest weight capacity of any towing component, such as your vehicle or the hitch of the trailer.

And again, the inner diameter is gonna be three inches. The outer diameter is 6 5/16 inches. The stud bolt size is M48 by 5-6H. And the overall length from end to end is sitting right at 10 5/8 inches long. And the stud length, measuring underneath the base of our ring to the end of the stud, is right at four inches long.

And it comes with everything that you see here, along with the pin. And that's gonna conclude our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

See what our Experts say about this CURT Lunette Ring

  • Correct Lunette Ring With Nut To Fit a 1-1/2" Mounting Hole
    It sounds like you are going to need the Buyers Products 2-1/2" I.D. Forged Alloy Steel Lunette Ring with Nut # 337BDB12503 that fits a 1-1/2" mounting hole. I checked the Buyers Products 3" I.D. Forged Alloy Steel Lunette Ring with Nut # 337BDB12492H in our warehouse and confirmed with Buyers Products that it has a 2"-4.5 thread pitch. This would require a 2" hole to mount the ring. The Curt Lunette Ring # C48530 with a m48-5 will also require a 2" mounting hole.

  • Pintle Hitches to Fit with a 3" Diameter Curt Lunette Ring
    We do carry a variety of pintle hitch options that are compatible with the 3" Diameter Curt Lunette Ring # C48530, you just need to choose the correct mounting style for your tow vehicle. Some of our options mount to a plate, like the part # C48215, while others install in a hitch receiver, like the part # BR27FR. If you can get me some more details on what you're needing for the tow vehicle side of things I'd be more than happy to help you choose the best option from our linked selection.

  • Distance From Ring to Nut of Curt Lunette Ring C48530
    The diameter of the shaft is indeed 2 inches, and the distance from the base of the ring when the nut is threaded on with the cotter pin in place is 2-1/16 inches for the Curt Lunette Ring # C48530. I have added a diagram below showing this for you.

  • Availability of Longer Shank Lunette Ring for Trailer
    The most similar lunette ring we offer that has a longer shank would be the part # 337BDB1238 which has an overall length of 20-3/8 inches but installs a bit differently. We do not have a similar style that you referenced that is longer.

  • Dimensions of Curt Stud Mount Lunette Ring # C48530
    I went out to the warehouse and pulled Curt Stud Mount Lunette Ring # C48530 and took some measurements for you. Take a look at the photo which shows the dimensions of the Stud Mount Lunette Ring. The dimensions are: Mounting stud, Threaded portion = 2" Nut requires a 3" wrench or socket Diameter of shoulder at top of threads = 2-1/64" Hole in center of Lunette = 3" Diameter of Lunette Ring itself = 1-5/8"

  • How Tight Does the Curt Stud Mount Lunette Ring have to Be to Still Allow it to Swivel
    You will want to be able to use the cotter pin to keep the nut in place on the Curt lunette ring # C48530. So it will need to be threaded in far enough for the pin to go through the shank of the ring to hold the nut on. Using flat washers will be fine as long as the nut can still thread on far enough.

  • Recommended Articulating Coupler for Off-Road Trailer
    It sounds like you might want to have a look at something like the Lock N Roll Articulating Hitch w/ 3-Position Channel - 2" Receivers - Vehicle Side - 11K # 336VS503505 which will slide into a 2" hitch receiver and give you a fully articulating solution that's designed for off-road trailers. You could then choose from a few options based on the style of the trailer. The part # 336TS528 is for a 2 inch straight channel, the part # 336TS504 is for an A-frame trailer, # 336TS506 is for a...

  • Recommended Lunette Ring Rated for 30,000 lbs Weight Capacity
    The Curt Lunette Ring - Bolt On - 3" Diameter - 22,000 lbs # C48510 is rated for 22,000 lbs weight capacity. It is not rated to stand up to 30,000 lbs so it could fail. To handle that capacity without deformation or issue, I recommend the Curt Lunette Ring - Stud Mount - 3" Diameter - 45,000 lbs # C48530 or the Curt Lunette Ring - Flat Plate Mount - 3" Diameter - 60,000 lbs # C48560.
