The Project X HZRDUS Black GEN 4 shaft continues to deliver the consistent, low launch, low spin performance we’ve come to expect. Friendlier feel than previous models.
While the golf industry races ahead, constantly churning out new products, there are some things that you can rely on. The Project X HZRDUS Black has become one of those standbys. Now in its fourth iteration, this shaft has become a staple on Tour and in the bags of everyday golfers who want low launch, low spin, and supreme ball control. I tested this latest version to see what Dual Torsional Design can do to enhance its performance.
The fourth generation HZRDUS Black gets an updated font and an overall cleaner look. The signature hazmat placard with the shaft’s specs remains, but a lot has been removed. We don’t even have the Project X branding beyond the HZRDUS logo that we had in the first generation [review HERE]. Similarly, there’s no “Smoke” or “Smoke RDX”. The only markings beyond the placard and HZRDUS logo is the “Dual Torsional Design” near the tip.
Installed logo down, you get a clean, gloss black look at address. I’ve always thought the HZRDUS shafts did a good job with their aesthetics, but, in contrast to this simplified look, the third generation version seems quite busy [review HERE].
Having tested every generation of the Project X HZRDUS Black, I had a pretty clear expectation for what this shaft would feel like. Still, the GEN 4 managed to surprise me. What I wasn’t expecting was the incredibly clean impact feel. Hitting this shaft vs. many others was like using a graphite putter shaft vs. steel. There were no excess vibrations, just a clear sense of ball meeting club face.
The Project X HZRDUS Black GEN 4 has the same stiff butt and tip sections with an ultra-stiff mid as its predecessors. This is a shaft that is going to stay rock solid no matter how hard you swing it. It’s built to resist high swing speeds and aggressive transitions, and it does that job marvelously.
All that said, this is the friendliest HZRDUS Black that I’ve swung. It’s never going to kick or “activate,” but it doesn’t laugh at your efforts either. Previous versions seemed to dare you to swing harder. GEN 4 handles whatever you throw at it without demanding that you swing all-out.

The engine behind the fourth generation of HZRDUS Black is Dual Torsional Design. In short, Project X makes the shaft with smaller “flags” to maintain a more consistent angle and create lower torque. If you want the full explanation with visuals, check out the video HERE.
Practically speaking, the Project X HZRDUS Black GEN 4 delivers the same performance we’ve come to expect. The stiff tip section keeps drives on a low, penetrating trajectory with low spin. For players that struggle with high spin or those that play in a lot of wind, this shaft can add distance and control.
In terms of accuracy, the HZRDUS Black GEN 4 is the kind of shaft that makes you fully responsible for your results. I’ve never swung a HZRDUS Black and thought, “That bomb/hook/slice/push/pull wasn’t what I was expecting.” Good swings produce laser-straight shots, bad swings tend to get what they deserve. That said, the low spin does reduce curve a bit, which helps to keep some poor shots in play.
Going back to the feel, the biggest change I noticed in GEN 4 is that I don’t need to give every swing 110%. The gentler feel allowed me to swing at 90% and enjoy the control this shaft offers without bringing in the high variance of all-out swings.
The Project X HZRDUS Black GEN 4 is available at 60, 70, and 80 grams. In both 60 and 70 grams, you can get 5.5, 6.0, 6.5, and TX flexes. The 80 gram version drops the 5.5 flex.
The Project X HZRDUS Black GEN 4 is a smart, iterative upgrade on a shaft that’s approaching classic status. Its new Dual Torsional Design allows for lower torque and more consistency without creating a harsh feel.
