Stainless Steel has never looked so good or performed so well. More than just flashy, Thunder delivers real power. The band is 20mm wide, 7.2mm thick, and weight ranges from 5.5 – 6.7 ounces. Rose style is 14kt Rose Gold plated.

Inside ring surface is comfort fit (as are all our rings), edges are rounded for ideal long term wear, and each ring is laser engraved with our very bold logo.

Pairs equally well with your best jeans, a favorite motorcycle jacket, or those chains you keep in your sex dungeon. It will also keep you hard a a brick.

    Different, but yet the same.

    This is my seventh ring, and yes it is different. Not quite as heavy as the tungsten carbide but somehow with a little added thickness it is more than heavy enough. The extra bulk provides a balanced feeling that is just enough different to be noticeable, but in a very GOOD way.

    But yet it is the same … outstanding quality, comfort and handsome beauty are the words I would use to describe King-Rings product and this ring doesn’t disappoint. Scott has done it again.

    I’ve owned a few cock rings before but this was my first King Ring. I was a bit unsure at first about paying so much for a cock ring. But when i saw the thunder I couldn’t stop myself. Now I’ve tried it I’m so glad I took the plunge.

    The ring looks beautiful and yet incredibly masculine and sexy. And it feels even better. It has a great weight without being too heavy. If you get the sizing rings you can ensure the perfect fit. It is really comfortable to wear for long periods too which is not something you can say for a lot of rings. And as for how it performs, you will really have to try it for yourself. All in all this is a great addition to an outstanding range. And you get great customer service from Scott as well.

    I’ve had Thunder for about a month now, and I neglected to review it until now because I honestly didn’t want to take it off. The packaging is exquisite and truly feels like you’re holding something special. Then you open it and see what’s inside. My eyes bulged at how awesome the ring looks in person. It looks like it’s not just another hunk of steel. Then you put it on.

    I have never worn a more comfortable ring. The fit was just right, it’s got enough weight to remind you that its there, yet it’s not so heavy that you fear it dropping down your leg with each step. But at the same time, it doesn’t pinch you and make you feel uncomfortable. It even stayed in place through hot summer days of high activity, keeping it on for a full week without having to readjust it. And it makes my package look exquisite. Finally, I went a round with it. That part I’ll let you experience for yourself.

    If you aren’t quite ready to jump into buying any of the Tungsten rings, Thunder is a good entry point. The price is most definitely higher than what you would pay elsewhere for similar stainless steel rings, but the quality of the ring is so worth it & the design sets it apart from your typical donut. And the customer service you get will definitely put a bow on the whole experience. Definitely a satisfied customer who will make another purchase!

    This is a big, chunky, masculine ring. The facet cuts are deep into the ring which add to the masculine feel and the matte finish applied to the central facets adds an extra touch of interest. The ring is lighter than other King rings which can make it easier for all day wear.

    Thunder is now my fifth King-rings and I’m very excited to be wearing a beautiful piece of art. This ring was comfortable from the very first time I put it on my cock. The thickness is bigger than most in Scott’s collection making it snug and in place. I chose the BRIGHT ring and taking it out of its package was truly a surprise. Your astounded by the quality craftsmanship which goes into making your ring . You can’t believe how bright it is either. Then all that’s on your
    mind is putting it on as soon possible.

    I wear King-rings 24/7 365 day a year that’s how much I love these cock rings. Scott certainly takes care of his customers as well, his customer service is five star ⭐️⭐️⭐️⭐️⭐️

    Once you try a King-ring you’ll never go back to wearing to a normal cock ring ever.

    I received my King Ring in the mailbox last week. The discreet packaging probably had my mail lady wondering what was so heavy in that little box. 😀

    I excitedly opened the descrete box and found the sexy presentation of a gold jewelry box. I really felt like I had just gifted myself something special. Once I pulled the lid off the box, the ring was professionally packaged, in a cellophane wrapper marked with rings size printed on the outside. Thoughtful.

    The ring also comes with a black Crown Royal type of soft storage bag for discreet carry and storage.

    I purchased the bright stainless steel Thunder because it resembles my wedding band almost exactly, although my wedding band is made of tungsten and the color isn’t as bright. The facets are cut exactly the same so they both pair great together.

    The weight of this ring is impressive, I have been comparing and wearing the sizing rings for over a year and when I put the Thunder on.. OMG it was amazing. Nice weight and tug on my dude.

    The edges are so much smoother than the sizing rings. I did sand smooth the edges on the plastic sizers to be more comfortable, but they still did pinch some.

    The Thunder though, doesn’t pinch because the edges are as smooth as my wedding band. I am so very happy with this purchase, I will be buying more. I can’t wait to buy the new Glans ring next.

    Scott and family have built an amazing business model. From the website, to the ease of purchase, the temporary sizing rings and the care thought into making sure you get the right size, to the packaging, the soft storage bag and the follow-up email, making sure everything was just right.

    If he had just thrown the beautiful badass ring in an envelope and mailed it, that would have been fine.. but I’ve been blown away.

    All the extras make this product and it’s excellent grade, weight and design, pushes my experience over the top. Now, I’ve got to plan a date night. This thing makes me last forever.

    Thanks for taking care of us dudes out here.

    I can’t say enough about the 5 star+ service received from Scott. Truly exceptional! I’m new to C rings and ordering the sizing rings was a perfect way to decide which was appropriate for my guys. When I received the actual Thunder ring I was truly impressed on how amazing it looked and felt. It really looked like a piece of jewelry. The finish and materials is A+++! The weight of this ring feels great too. Wearing this when I’m out makes me feel confident and secretly hiding something special. I’m ecstatic about this purchase and will definitely want to order other styles!

    Thunder is my second King Ring and I am very pleased with this ring. It is a substantial ring in terms of size and appearance yet lighter than the other King Rings due to it being made of stainless steel rather than tungsten. The lighter weight means less of a tug when wearing it, but it doesn’t mean that the ring is any less impressive.

    I own a number of rings about the same size as Thunder but none are as comfortable to wear. I generally wear a ring unless I’m in the shower or sleeping. The attention paid to the inner design of Thunder makes it one of the most comfortable rings I own to wear all day. The tapered inside has a smooth transition on the edge so Thunder won’t ever pinch. That little difference in design makes a big difference and your member will appreciate it.

    Thunder is visually striking when it’s sitting on my dresser; when I’m wearing it it looks amazing. The mirror polish on the outer rows of bricks catch and reflect light to attract attention to the ring. If you’re lucky enough to see it in sunlight you’ll find Thunder dazzling to behold. The design suggests a castle wall erected around the root of my member and when I have an erection Thunder frames and enhances beyond my expectations.

    Best of all Thunder comes with the fantastic customer support from Scott at King Rings. Scott’s passion and commitment to quality craftsmanship and design is very welcome. It is about time that men have rings of this quality available. Many thanks!

    This is my 2nd ring from King Rings. My wife ordered Thunder as a Birthday present for me. Which was really lovely of her. Now I have to say she is not all sweetness and light and can be a bit wicked to me. Thunder arrived some 2 weeks prior to my Birthday and with great anticipation I opened the package and inside found the Thunder in Rose Gold. I was told to try it on straight away and so did. Wow we both loved it. The colour, fit and look is just amazing. I had it on for about a minute before it was taken off of me and I was told I was not getting it back until my actual Birthday. Now let me tell you, that was the longest 2 weeks of my life. Any way Birthday arrives and I get the enjoyment of opening the packaging again and once again setting my eyes on such a wonderful ring. I wear it all the time (well interspersed with Island Wood) and it is so comfortable and stunning. Once again Scott has done us proud. Yes the rings are expensive but they are well worth the money and so much better quality than any others I have worn. Thanks so much for such a great product and service which was yet again first class

    There are two kinds of people: junk or jewels. If you’re a “junk” guy, by all means stick with the cheap rubber or ugly steel cock rings. If, however, you are a “jewels” kind of guy, you’ve found the right place. My thunder ring is beautiful–the heft and craftsmanship can be summed up with “holy shit.” I paired it with a rose gold glans ring and the whole experience is just fantastic. The jewelry is clearly high quality, feels really good when it is on, and evidently, quite the crowd-pleaser.

    The personalized service from Scott and team is exactly what you’d expect from a premium product.

    I’m afraid I will have a whole collection of King Rings in the near future.

    Beautiful ring and very well made. The ring fits nicely but is a heavy ring. Would consider going a size smaller in view of the weight for an ultra secure fit.

  12. Todd (verified owner)

    Just received my Thunder cock ring and I couldn’t be more pleased! It’s actually better than I had expected. The weight, design, and overall look make for THE best c-ring I’ve ever purchased – seriously! It’s a prime example of “you get what you pay for”! I actually wear it 24/7, as it’s so comfortable. In addition to the great quality of the ring itself, the customer service outreach (proactively!) was bar none. I’ll definitely be a “repeat customer”!

  13. David (verified owner)

    Great ring, love the feel and look of it. The shine between the contrast and texture on the metal demands attention. Out of my collection of all my king rings – this ring is becoming my go to ring for my casual days.

    Thank you Scott for the great service and customer service.

  14. Stephen P (verified owner)

    I’ve been wearing c-rings for several years and this is by far the best I’ve ever worn. I also purchased the same sized trial ring at check out to ensure proper fit. I was a bit concerned on the tightness of the trial ring, but after exchanging emails with Scott I felt confident in trying on Thunder. I knew as soon as I put Thunder on that I made the right decision. The overall look, weight, and width just makes it feel right. Best of all, my bride of almost 30 years likes it as well. There is no better endorsement than that.

    The customer support truly puts this company over the top. I never expected to hear from the company unsolicited. The service is second to none.

    I can confidently say you will not be disappointed.

    First and foremost, a huge THANK YOU to Scott for his outstanding customer service! I truly appreciated his honesty and the advice he provided me with to ensure my first purchase of both a c-ring and g-ring would be just the right fit for me. His recommendation to purchase the sizing rings was no doubt the best advice ever. I took the time trying on different sizes until I was certain of my choice was the right tailor-fit rings for me. As an added bonus for purchasing the sizing rings (both c and g-rings) he provides his customers with a credit x2 (for each set) towards your purchase of your king rings products!

    When I received both my rings, I was amazed to see how stunning and exquisite they looked.The design and craftsmanship is beautifully executed. His advice = They are just the right fit indeed!. Wearing a 3 oz g-ring for the very first time was totally out of this world! Feeling that weight pulling down is amazingly exciting and WoW very impressive! I have been wearing both rings every day and I never leave the house without them on! Every man should have a g-ring! They compliment your c-ring so exquisitely and most of all make you feel and look like a king!!

    I am totally pleased and proud to own and wear the King Ring products! I’ve already started saving for my next set of rings. 😉

    Yo I just received my Thunder C-ring today, and I am very, very satisfied with it. I am glad that I did my research and waited for the right choice and making the decision to go with King rings. I will be purchasing another C-ring the True-Blue when available, but until then I will be purchasing a Glans ring from King-rings.

  17. James B (verified owner)

    What a top notch experience!

    The customer service has been absolutely incredible.

    You are definitely going to be amazed when you hold this ring in your hand. Now just imagine what it is going to be like when you try it on for the first time.

    I am now a loyal customer. Without a doubt, there will be another ring purchased.

  18. Jayson (verified owner)

    I’ve had my Thunder for a few days and have definitely not been disappointed. The weight is perfect and it feels amazing, as long as you get the sizing right. Comfortable enough for all day wear. Customer service is amazing and upgraded my shipping for free! Highly recommend!
