What KHT does
- 01
Lightweight
20–30 g lighter than a conventional shaft, and that much strain off your body.
- 02
Force transfer
Whatever your swing speed, the shaft optimizes how your power reaches the ball.
- 03
Precision
It settles the swing into a stable shape, and accuracy follows from that.
- 04
Distance
Power transfer and flexibility working together: farther, and more precisely.
Model by model
autoFlex Original
The shaft that changed the game. Lightweight construction and KHT maximize power transfer for more ball speed and longer carry and roll. Driver weights 41–57 g; flexes cover 70–120 mph club speeds.
Dream 7 & Joy 365
Generation 2: Japanese carbon prepreg and second-generation KHT. Dream 7 adds a new tip section for impact; Joy 365 adds a softer feel and extra kick for slower swings.
AUTOPOWER KHT
Tour-level stability. T1100 carbon fiber minimizes shaft distortion and optimizes power transfer at impact, for advanced players seeking precision.
Checked by hand
Shaft CPM is measured before shipping, and the final check is done by hand, not machine. Every genuine shaft carries an engraved 12-character code. Verify your shaft
