Autoflex Original SF 505XX Pink & Black Driver Shaft

AutoFlex Original SF 505XX Pink Driver Shaft

The AutoFlex SF 505XX Driver Shaft is built for high-speed players seeking maximum stability, speed, and distance from a lightweight, high-performance design.

With a 57g construction and optimised for 110–120mph swing speeds, it delivers a powerful combination of high launch, controlled feel, and efficient energy transfer.

The AutoFlex SF 505XX is engineered for golfers who generate higher swing speeds and require a shaft that can maintain stability without sacrificing speed.

Utilising AutoFlex’s unique construction, the shaft stores energy during the swing and releases it rapidly through impact, helping produce increased ball speed while maintaining control. It offers a modern performance profile that differs from traditional, overly rigid shafts.

Performance Overview

The SF 505XX is designed to produce a high launch, mid spin ball flight, allowing players to maximise carry distance while maintaining a strong, controlled trajectory.

It is built to load efficiently and recover with speed, even at higher swing speeds. Compared to other models in the range, the 505XX provides the highest level of resistance and stability, making it ideal for aggressive transitions and powerful swings.

This results in a combination of explosive distance, improved consistency, and tighter dispersion at higher speeds.

Key Technologies

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

Lightweight high-performance design
At 57g, the shaft balances speed with maximum 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.
