The Project X LZ (Loading Zone) Graphite Shaft is engineered for golfers who want explosive energy transfer without sacrificing stability or control. Designed using Project X’s advanced Loading Zone Technology, this shaft stores more energy during the transition and releases it aggressively through impact for maximum ball speed and added carry distance.

What Makes the Project X LZ Different?

Unlike traditional graphite shafts with uniform stiffness profiles, the LZ features a strategically softened mid-section — the heart of the “Loading Zone.”

This softer centre section:

• Increases shaft deflection during transition
• Promotes stronger loading in the downswing
• Delivers a powerful, controlled kick at impact
• Enhances ball speed and carry distance

The tip and butt sections remain firm and stable, preventing unwanted twisting or excessive spin. The result? A shaft that feels lively without ever feeling loose.

Performance Profile

• Launch: Mid to High
• Spin: Mid
• Bend Point: Low/Mid
• Construction: Premium Graphite
• OEM Version: Manufactured by Grafalloy/Project X

This profile suits players looking to increase launch and ball speed while maintaining control through impact.

Who Is This Shaft Ideal For?

The Project X LZ Graphite Shaft is ideal for golfers who:

• Want more carry distance without switching to ultra-light shafts
• Have a smooth-to-moderate transition and want better energy transfer
• Need mid/high launch with controlled spin
• Prefer a stable feel but with noticeable kick through impact

It’s especially effective for players who feel their current shaft is too “boardy” and doesn’t load efficiently during transition.

Technology Breakdown – Loading Zone (LZ)

The LZ design creates a performance hinge in the mid-section of the shaft. During the downswing, this section stores more energy than traditional designs. At impact, that stored energy is released efficiently into the ball, producing:

✔ Increased head speed
✔ Higher ball speed
✔ Improved carry distance
✔ Stable dispersion

This balanced profile gives you the power of a softer shaft without sacrificing the control of a stable tip section.

Premium Finish

The Project X LZ features a distinctive aesthetic:

• Matte black mid-section with visible woven carbon fibre
• Blue and silver detailing on the butt and tip sections

A premium performance look to match its performance profile.
