The Autoflex shaft has built a cult following — and raised plenty of eyebrows. Lightweight, whippy, and unapologetically pink, it promises something every golfer wants:
Effortless distance and improved accuracy — with less effort.
Too good to be true? Let's break down why Autoflex shafts are so good — and for whom.
The Autoflex Proposition: Swing Easier, Hit Farther
What makes Autoflex stand out isn’t just its color — it’s the philosophy:
- The shaft is designed to load more without requiring a faster swing
- It adapts to your natural tempo, whether you swing at 85 or 110 mph
- The result? More ball speed and tight dispersion — with less exertion
Autoflex isn’t just a shaft — it’s a cheat code for efficiency.
The Secret Sauce: K.H.T (Korea Hidden Technology)
Autoflex doesn’t publish exact materials or flex specs. Instead, they use K.H.T., a proprietary formula that creates a unique combination of:
- Ultra-lightweight carbon fiber
- Variable stiffness zones that react to your swing
- A "whip" feel that doesn’t sacrifice control
This means the shaft does more of the work for you, especially at moderate swing speeds (90–100 mph).
Who Should Use It?
Autoflex works best for:
- Golfers with moderate swing speed (90–105 mph)
- Players with a smooth tempo (not for violent transitions)
- Seniors, mid-handicappers, or anyone chasing more distance without changing their swing
⚠️ Big hitters with fast transitions might find it too soft unless they test stiffer versions like the SF505X or SF505XX.
Tour Validation (Yes, Really)
While Autoflex is unconventional, it’s not a gimmick. It’s been tested by Tour pros, including:
-Bernd Wiesberger (European Tour)
-Dustin Johnson reportedly tested it during practice rounds
And plenty of YouTubers and fitters (like Club Champion) have confirmed that, when fitted properly, it can outperform traditional shafts.
The Catch? The Price
At $700+, Autoflex isn’t cheap. But for some players, the extra yards and reduced fatigue are worth every dollar.
Final Verdict
Autoflex shafts are good because they flip the script: you don’t need to swing harder to hit farther. They deliver distance through efficiency, not force.
Want a shaft that adapts to you? Autoflex might be the upgrade you never knew you needed.
