The included adapter and grip simplify fitting, especially for those rebuilding multiple clubs or testing different swings.
- Includes adapter and grip for simple installation.

Best for aggressive, fast-swing players seeking low launch and high stability. The 6.5 X-Stiff designation targets a specific feedback profile and helps control dispersion at higher speeds. This shaft is a strong option for players who want to maximize accuracy on powerful swings in a 40-inch form factor.
- Higher stiffness promotes reduced twisting at impact.
- 75g weight aids feel for faster tempo without excessive tip stiffness.
Best for: players with fast swing speeds who need a tight shot dispersion. Limitation: may feel overly firm for slower tempos.

The .335 tip for drivers ensures compatibility with common fittings, while remaining a cost-efficient choice for custom builds.
- Lightweight graphite construction supports swing speed increases.
- Multiple tip sizes allow broader fitting options.
Best for: budget-conscious players building or updating a driver. Caution: uncut length requires professional shortening and install expertise.
Buying Guide
What should I consider when choosing a 40 inch driver shaft?
Key factors include flex (how much give the shaft has), weight, tip size, and material. Graphite shafts are lighter and can help speed, while specific flex choices tailor launch and feel to your swing tempo. Ensure the shaft length matches your swing span and is comfortable in your stance.
How does flex impact performance?
Faster swingers typically benefit from stiffer flexes to reduce twisting and preserve accuracy. Slower tempos may gain from regular or senior flex for higher launch and better feel. Always confirm your current swing speed and tempo before selecting a flex.
Is a grip/adapter included important?
Yes, a grip and adapter simplify installation and ensure a secure fit. If a shaft is listed as uncut, you’ll need to supply a compatible grip and adapter separately or choose a version that includes them.
