Buyers Products Bolt-On 5/8" Forged D-Ring spreads the pull to the entire mounting plate instead of concentrating it on a single point. Its bolt-on design means you don't have to weld, so it's great for flat surfaces where welding is not an option. The 5/8" diameter D-ring comes with a forged mounting bracket welded onto a steel plate. A black powder coated finish adds durability and corrosion protection. Mounting hardware and two back support bars are included. Be sure to check the capacity of the surface you are mounting on prior to use. D-rings are not approved for overhead use.


  • 4-Hole mounting bracket helps spread pull force to multiple anchor points
  • Versatile uses across many applications
  • Corrosion-resistant black powder-coated finish
  • Strong forged steel construction
  • Working load limit: 6,130 lbs
  • Ring diameter: 5/8"
  • Inner dimensional height: 3"
  • Inner dimensional width: 3"

Buyers Products 5/8" Forged D-Ring With 4-Hole Integral Mounting Bracket - 337B40MP

Average Customer Rating:  4.9 out of 5 stars   (8 Customer Reviews)

by:

Mounted on the rear floor edge of my side x side trailer. I have a chain attached to the D Ring & then drops over the trailer ball on my machine. Absolutely no way the machine can go forward in a panic stop situation. Great piece of mind while in motion. I purchased a WLL of three times the weight of the machine. I can always trust E Trailer to have exactly what I need for towing. 720470

These are easy to install and are very sturdy...would work for any atv/utv...customer service is great also...prompt responses...would use E trailer for all my trailer needs 873009

by:

Not wanting to weld on my new trailer, I purchased these instead. Using the included backing plates, you will need a half inch longer bolts to go through a 2x6 floor. Installation was very simple. I would have given 5 stars, but had to purchase longer bolts. Overall, a very fine product. 853877

This ring was mounted on the front of my 7x12 trailer, through the wood floor and through the metal frame. I use the ring to pull my 1800 lb stump grinder onto trailer when it broken. I use it a lot and it works perfectly! Etrailer.com is my number one go to when trailer parts are needed . Also purchased a really nice class IV trailer hitch for my ‘04 Jeep Wrangler. Fit perfect, easy one person install. Works great! If Dena don’t have it, you don’t need it. 818292

Excellent product, I installed 6 of these on my car hauler, four for the cars, and two on the sides for the motorcycles. They are very well constructed, I had to purchase longer bolts since they weren’t long enough for the floor boards. Definitely would recommend, should also get the strap kit etrailer sells, it comes with a very nice zippered bag, you will be all set to haul anything safely. 812240

  • What is the Capacity of Buyers Products 5/8 Forged D-Ring 337B40MP
    The Buyers Products 5/8" Forged D-Ring # 337B40MP has a working load limit of 6,130 pounds. The break strength data was not provided. Usually the working load limit is a third of the break strength but again the exact figure is not provided. The capacity will also depend on what you have the D-ring mounted to. So for example if mounted to a steel frame you will likely be able to reach the WLL capacity. Attached to 1/2 inch plywood, not so much.

  • Can Curt C45832 Tow Strap Loop Be Used to Tie Down a UTV
    The # C45832 strap loop itself has a 13K capacity, so the strength of this part itself wouldn't be an issue. If the combined capacity of the receiver hitches is greater than the 2370 lb dry weight of your UTV, this would be a good way of tying it down. If the receivers don't have that kind of capacity, I'd use a more traditional tie down setup like a couple of D-rings such as # 337B40MP and two ratchet straps like # BDW20325. You could rig it up as shown in the provided video.
