autoFlex and AUTOPOWER shafts are made in Korea by DUMINA and brought to the US by DUMINA Golf America, from our headquarters in La Habra, California.
01 · Korea Hidden Technology
The secret behind every swing.
We make one of the most copied shafts in the world, so protecting it became part of the job. Materials, layup, process: how it's made is not public. The name says it: Korea Hidden Technology.
The results, however, are fully public. Every launch monitor prints them.
Explore the technology →Lightweight
20–30g lighter than a conventional shaft, and that much strain off your body.
Force transfer
Whatever your swing speed, the shaft optimises how your power reaches the ball.
Precision
It settles the swing into a stable shape, and accuracy follows from that.
Distance
Power transfer and flexibility working together: farther, and more precisely.
Checked by hand. The final check is done by hand, not machine. Every shaft is individually inspected before it ships.
02 · Genuine only
One of the most counterfeited shafts in the world.
A fake can look right and cost almost as much, but it will not perform or last like the real thing, and it cannot be serviced under warranty.
Korea Hidden Technology cannot be made outside the DUMINA factory. A copy can match the look, never the inside. Buy from us or an authorized dealer to be sure your shaft is genuine.
