KZU 6-Piece Driver Weights Kit for Callaway Elyte – 5g–23g Precision Mass Weights

Recharge your driver setup with precision tuning

The KZU 6-Piece Driver Weights Kit is designed for golfers who value consistency and control off the tee. Crafted from high-density tungsten and CNC-milled to tight tolerances, these weights are engineered to preserve aerodynamics while delivering repeatable data across sessions. Compatible with Callaway Elyte driver weight ports, the system supports a wide swing-weight range (C9–D6) and offers a practical path to refined launch and spin behavior without overhauling your swing.

Key positioning options let you tailor flight characteristics. The posterior 23 g element can boost MOI by approximately 12%, contributing to stability on off-center contact. Conversely, placing the lighter 5 g weight toward the front can yield a lower-spin, penetrating trajectory for potential distance gains. These adjustments are designed as possibilities to explore, not guarantees, helping you discover what feels and performs best under real playing conditions.

What you get

• Six precision tungsten weights: 5g, 7g, 9g, 15g, 19g, 23g
• 1 Callaway Elyte-compatible driver head weight kit
• 1 compact transport bag for on-range use

Engineering and installation highlights

• Nine mass options (5g–23g, 2g increments) cover a broad swing-weight spectrum (C9–D6)
• ±0.2 g machining tolerance ensures repeatable performance data
• Predictable ball-flight modulation: roughly ±3° launch adjustment and ~50 rpm spin change per 5 g increment
• Thread-lock interface with anti-vibration serrations; standard T9 torque wrench required
• 35 N·m fastening torque maintains positional stability at speeds over 120 mph

The 23 g weight positioned toward the back elevates MOI for stability, while front-weighting with 5 g supports a lower-spin trajectory. This combination empowers players to experiment with shaping shots in practice and on course, providing a tangible sense of how weight distribution affects flight dynamics.

In real-world use, expect a steady, repeatable feel when swapping weights. The kit is designed to help you fine-tune launch conditions and shot-shaping capabilities to suit individual swing profiles, game plans, and testing sessions, all while maintaining a clean, aerodynamically-conscious profile at impact.

Usage tips

• Start with the 23 g rear weight for stability, then experiment with forward weights to modulate spin.
• Mix and match weights within the range to explore subtle changes in launch angle and flight path.
