Designed and engineered by strength athlete and coach Chris Duffin and his design/engineering team.

Carefully Crafted

Designed and manufactured in-house at our world-famous facility – Kabuki Strength Lab

USPA and IPL Approved Bars

Both of our New Generation bars (Power and Squat Bar) are approved and certified for use in the USPA and IPL.

250k+ PSI Tensile Strength

Our proprietary manufacturing process allows us to make the hardest, most durable bar the industry has ever seen.

  • Are the Bars Certified or Approved for use in any Powerlifting Federations?

    Yes! Both the Power Bar and Squat Bar are USPA and IPL approved for competition use. We are seeking out further approvals and certifications from other accreditation bodies, and both of our bars conform to international competition specs.

  • When are the bars available?

    The pre-sale period for the New Generation bars is over and pre-sale units are being shipped to pre-sale customers. Bars are now priced at retail and if there is a lead-time it will be posted on the individual product page on the store.

  • How much do the Power Bar and Squat Bar cost?

    The retail price for the Power Bar is $599, and the Squat Bar is $699.

    Pre-orders of both bars are discounted 10% off the retail price, so the Power Bar is $540 and the Squat Bar is $630 during this pre-sale period. 

  • What makes this bar different from others?

    Both of our new generation barbells, the power bar and squat bar, are made of a aerospace-grade steel alloy that is hardened to over 51 Rockwell and over 250,000psi Tensile Strength using our proprietary process. As far as we know, this is the hardest bar on the market and nobody even comes close to offering a bar with these metallurgical specifications.

    Chris describes why “hardness” and “tensile strength” matter and what they mean in the video below titled “Metallurgy 101” so make sure to check that out!

    What this means in a nutshell, is that our new generation bars are the most durable, long-lasting, and high-quality barbells on the market right now. They are also priced very competitively compared to higher-end bars which are still fall under ours when comparing specifications.

  • Does the power bar meet the specifications for a competition power bar?

    Yes, the power bar was designed with IPF/USAPL and IPL/USPA specifications in mind and fits within their required specs for a competition power bar.

  • What warranty do the bars come with?

    We guarantee our bar materials and workmanship for life and claims are handled on a case-by-case basis by our customer service team.

  • What is the difference between the Power Bar and the Squat Bar?

    See below for full specifications for each bar. The Power Bar is a 20 kilogram barbell commonly used in powerlifting meets as a 3-lift bar – for the squat, bench press, and deadlift.

    The Squat Bar is a specialty barbell that weighs 25 kilograms, is thicker and longer than a regular bar, and is used by many federations for the squat. Most big  (800+ pound) squats you’ve seen in competitions are done on a squat bar like ours.

Let’s be honest, there’s a lot of barbells out there from a lot of manufacturers. Some have been around for decades, while others just recently showed up on the scene.

So what’s the difference? Why should anybody care to buy our barbell versus the other guys’?

Because of who we are, and why we do what we do. Our mission statement is simple – we are an organization devoted to optimizing human ability via innovative equipment, world-class coaching, and research-based education. When we make a piece of equipment, we make it because there is a gap in the current market, a need for improvement, or because we think we can do it BETTER than all the other guys.

Bar science is metallurgical science, the branch of science and technology concerned with the properties of metals and their production and purification. Our chief-engineer and co-owner knows a thing-or-two about metallurgy, having worked in the manufacturing industry for decades and having dealt with high-tech components for very, VERY expensive products like the Boeing 737 jetliner.

We saw the current bars out there and started playing around with making our own. During this period of design, testing, retesting, and more testing; we realized that we came up with something incredibly rare. A high-performance barbell that is more durable than any bar on the market. But why don’t the other guys make a more durable bar?

Because they can’t.

With higher “hardness” and “tensile strength” comes the increased risk of catastrophic failure in a bar under load. But we figured out a way to make a 250,000+ PSI bar that performs as well, if not better than the leading bars in the industry…without any risk of fragility or failure. But “why?”, you may ask…

Because we wanted to make a high-quality bar that you could use for the rest of your life, and pass down to your kids and them to their kids. Don’t believe us? Take our bar and start sawing your other bars and see what happens (please don’t do that – all bars deserve love and to be used properly).

The Kabuki Strength New Generation Bars all come with a 5 year warranty on the knurl. If it wears down to an unacceptable level, we’ll give you a new bar free of charge. It is built using the highest-grade American steel using proprietary in-house processes and hand-assembled using the perfect mix of hardware designed for longevity, and high-performance for a bar of its type.


Testing occurred throughout the entire development process for our new generation bars. Materials selection involved testing to determine the optimal steel alloy to use. Lots of testing was performed on the hardening process and figuring out a way to create the hardest bar while still allowing for whip and preventing the bar from snapping. The knurl took us many many revisions to figure out until we all agreed on the production version of the knurl – something we consider to be the best knurl in the industry. Overall this bar has been tested and retested hundreds of times with every feature and specification in mind.


In this video, our chief engineer and co-owner Chris Duffin discusses the metallurgy and science of barbells. He explains what the common numbers are data are used to describe barbells and what they mean practically in real-world performance. If you’re not convinced our bar is the best, this video will explain factually and objectively why it is.


This video shows a knurl test performed on our bar against a competitor’s power bar. The test had two components: 1) Our bar held stationary against a spinning competitors bar (on lathe) and 2) The competitor’s bar held stationary against our spinning bar.


The GOAT himself, Ed Coan stopped by the Kabuki Strength booth when we were down at the US Open in San Diego and had this to say about our new generation bars…


So what do all these numbers and figures below mean? Chris explains the metallurgy and science behind the bar in the video above in a very concise and easy-to-understand way. Although we can’t disclose detail about our proprietary manufacturing process, we can say with certainty that we’ve produced the hardest, most durable bar the market has ever seen. Not only do the numbers back this up, but it’s performance in real-world and stress testing also demonstrates this. Nobody has ever brought a production bar this hard to market (over 250,000psi and 51 Rockwell) because doing so without risking catastrophic failure (bar snapping under load) is a difficult challenge. We’ve taken it upon ourselves to spend hundreds of hours researching, experimenting, and figuring out a way to create the ultimate barbell – a hard bar that performs well and will outlast its owner! Chris isn’t joking when he says in the video above that this is a bar you can pass down to your children.

Tensile Strength
The tensile strength of a material is the maximum amount of tensile stress that it can take before failure, such as breaking or permanent deformation. Our bar has the highest certified tensile strength of any barbell on the market.
Rockwell Hardness
The Rockwell scale is a hardness scale based on indentation of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload. In practical terms, the hardness will directly correlate to the longevity of the knurl.
Knurl Wear
Our bar withstood a knurl test for 300 seconds before we stopped the test. The knurl test involved using our barbell as the cutting tool against other barbells (and our own) spinning on a lathe. Other competitor bars lasted for 5 and 7 second respectively before their knurl completely failed.
Deformation @ 34,000N
In a deformation test using 34,000N force, our bar experienced 3x less deformation (.125 inches) than the average of both competitors bars.
