HZRDUS 6.5 Black 70g Gen 5 Extra Stiff Flex Driver Shaft

The Project X HZRDUS Black Gen 5 70 6.5 Extra Stiff Driver Shaft is engineered for powerful golfers who demand low launch, controlled spin, and exceptional stability at higher swing speeds.

Featuring advanced 4D Optimized Carbon technology, the Gen 5 Black combines the unmistakably controlled character of HZRDUS with refined feel and outstanding torsional stability, giving aggressive players the confidence to swing at full speed without sacrificing control.

Overview

The Project X HZRDUS Black Gen 5 70 6.5 Extra Stiff represents the latest evolution of one of the most recognised low-launch, low-spin shaft profiles in performance golf.

HZRDUS Black has always been designed for golfers who create significant load during transition and require a shaft capable of remaining composed throughout an aggressive downswing.

With Gen 5, Project X takes that stability-focused philosophy further.

The latest construction incorporates 4D Optimized Carbon technology, strategically reinforcing critical areas of the shaft to improve torsional stability and maintain more consistent behaviour as the shaft is loaded and released.

In the heavier 70g platform and 6.5 Extra Stiff flex, those characteristics create a particularly controlled setup for stronger golfers.

Rather than allowing excessive shaft movement during transition, the profile provides substantial resistance and a connected sensation between the hands and clubhead.

The result is a driver shaft built for golfers who want to generate speed aggressively while maintaining trajectory control, predictable spin, and confidence through impact.

Performance Overview

The HZRDUS Black Gen 5 70 6.5 is engineered around a low launch, low spin profile, producing the strong, penetrating trajectory preferred by many faster-swinging golfers.

Its defining characteristic is stability under load.

During an aggressive transition, the shaft's reinforced structure helps resist excessive twisting and deformation. This allows the golfer to apply speed without feeling that the clubhead is becoming disconnected or unstable during the downswing.

Through impact, the controlled tip and midsection help maintain more predictable clubface delivery, supporting tighter dispersion and consistent launch conditions.

The 70g weight class further enhances that controlled sensation.

Compared with lighter 60g driver shafts, the additional mass provides greater awareness of the club throughout the swing and can help golfers with powerful transitions maintain rhythm and sequencing.

The 6.5 Extra Stiff profile adds another level of resistance for players capable of loading the shaft aggressively, making this combination particularly well suited to golfers whose speed or transition can overpower softer shaft profiles.

The result is a shaft that delivers:

• Low, penetrating launch
• Controlled low-spin performance
• Exceptional stability at higher swing speeds
• Strong resistance to aggressive transitions
• Tighter dispersion and predictable ball flight
• Greater clubhead awareness from the 70g platform

Key Technologies

4D Optimized Carbon Technology

Advanced carbon fibre reinforcement is strategically positioned to improve torsional stability in critical areas of the shaft.

This helps the shaft maintain its structural integrity under load and promotes more consistent recovery through impact.

HZRDUS Black Performance Profile

The Black profile is engineered around low launch, low spin, and maximum stability, making it particularly suited to golfers who naturally generate significant speed, launch, or spin.

Reinforced Midsection

The midsection is designed to resist excessive deformation during transition, helping stronger golfers maintain control when applying significant force to the shaft.

Stable Tip Profile

A controlled tip section helps manage dynamic loft and spin while supporting consistent clubface delivery through impact.

70g Control Platform

The heavier weight profile provides a substantial, connected feel throughout the swing, making it particularly effective for golfers who prefer additional shaft weight for control and awareness.

Player Profile

This shaft is ideally suited to golfers who:

• Have faster to very fast swing speeds
• Play an Extra Stiff shaft profile
• Have a strong or aggressive transition
• Generate excessive launch or spin
• Prefer a heavier 70g driver shaft
• Want maximum stability through impact
• Prefer a penetrating rather than elevated trajectory
• Prioritise dispersion and control at higher speeds

The 6.5 (Extra Stiff) flex is intended for stronger players capable of consistently loading a firmer shaft profile.

As a general guide, it is most likely to suit golfers around the 105–115+ mph driver swing speed range, although transition, tempo, release pattern, driver head characteristics and finished playing length are equally important when determining the correct fit.

Why Choose the Project X HZRDUS Black Gen 5 70 6.5

The HZRDUS Black Gen 5 70 6.5 is built for golfers who don't need help creating speed — they need a shaft capable of controlling it.

At higher clubhead speeds, unwanted shaft movement can influence dynamic loft, face delivery and strike consistency. The HZRDUS Black philosophy is designed to minimise those variables by providing a stable platform that stronger golfers can load aggressively without losing confidence in the clubhead.

The 70g construction adds a substantial, controlled feel, while the Extra Stiff profile provides the resistance required for powerful transitions.

Combined with the low-launch, low-spin characteristics of HZRDUS Black, this creates a driver shaft particularly suited to players looking to flatten trajectory, manage spin and tighten dispersion.

With this shaft, you can expect:

• Strong, penetrating driver flight
• Lower launch and controlled spin
• Exceptional stability during aggressive transitions
• Greater control at higher clubhead speeds
• Tighter and more predictable dispersion
• Increased clubhead awareness from the 70g profile
• A firm, connected feel from transition through impact

This is a tour-inspired premium graphite driver shaft engineered for golfers who generate serious speed and want a shaft capable of keeping that power under control — combining the low-spin DNA of HZRDUS Black with the advanced stability and refined construction of the Gen 5 platform.
