Autoflex Original SF 405 Pink & Black Driver Shaft

AutoFlex Original SF 405 Pink Driver Shaft

The AutoFlex SF 405 Driver Shaft is a lightweight performance shaft designed to increase clubhead speed, ball speed, and overall distance through its uniquely responsive profile.

With a 45g construction and optimised for 85–100mph swing speeds, it delivers a powerful combination of high launch, efficient energy transfer, and effortless performance.

Overview

The AutoFlex SF 405 is engineered for golfers who want to maximise distance through speed, timing, and advanced shaft dynamics.

Using AutoFlex’s proprietary design philosophy, the shaft works differently from traditional models — storing energy during the swing and releasing it efficiently through impact to generate increased ball speed without requiring additional effort.

Performance Overview

The SF 405 is designed to produce a high launch, mid spin ball flight, helping golfers achieve strong carry distance with optimal trajectory.

Its defining characteristic is its ability to load deeply and recover quickly, creating a powerful release through impact. This enhances ball speed while maintaining control, allowing players to benefit from increased distance without excessive dispersion.

Despite its active profile, the shaft remains stable through impact, delivering a consistent and repeatable ball flight.

Key Technologies

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

Lightweight high-performance design
At 45g, the shaft promotes faster swing speeds while maintaining enough structure to ensure stability and control.

Dynamic load and release system
Engineered to optimise how the shaft stores and releases energy, improving timing, speed, and overall efficiency.

Player Profile

This shaft is ideally suited to golfers who:

• Want to increase distance through higher clubhead and ball speed
• Have moderate to faster swing speeds
• Benefit from a responsive, dynamic shaft profile
• Prefer higher launch with efficient spin characteristics

The SF 405 model is best suited to players with clubhead speeds in the 85–100 mph range, with fitting influenced by both tempo and transition.
