Autoflex Original SF 505X Pink & Black Driver Shaft

AutoFlex Original SF 505X Pink Driver Shaft

The AutoFlex SF 505X Driver Shaft is engineered for golfers seeking maximum speed, stability, and distance from a lightweight, high-performance design.

With a 55g construction and optimised for 100–110mph swing speeds, it delivers a powerful blend of high launch, controlled feel, and explosive energy transfer.

Overview

The AutoFlex SF 505X is designed for players who want to maximise performance through efficient energy transfer, improved timing, and advanced shaft dynamics.

Built using AutoFlex’s unique design philosophy, it behaves differently from traditional shafts—storing energy during the swing and releasing it rapidly through impact to increase ball speed without requiring additional effort.

Performance Overview

The SF 505X produces a high launch, mid spin ball flight, helping golfers achieve strong carry distance while maintaining a controlled, penetrating trajectory.

It is engineered to load efficiently and recover with speed, creating a powerful release through impact. Compared to other models in the range, the 505X offers increased resistance and stability, making it ideal for players with stronger, faster swings.

This results in a combination of high ball speed, improved consistency, and tighter dispersion.

Key Technologies

Korea Hidden Technology (KHT)
A proprietary internal structure that controls how the shaft bends and recovers, maximising energy transfer and overall performance.

Lightweight high-performance design
At 55g, the shaft balances speed and stability, allowing stronger players to generate power without losing control.

Dynamic load and release system
Optimised to store and release energy efficiently, enhancing timing, ball speed, and distance.
