2pc Mizuno ST-Z 220 / ST-X 220 Driver Weight Screw – 16g & 20g

Tailored performance for Mizuno ST-Z 220 and ST-X 220 drivers

This two piece weight screw set helps you fine tune how your driver behaves off the tee. With the included 16g and 20g weights, you can explore subtle shifts in launch angle, stability, and feel without changing clubs.

Two-piece design for quick setup

Each package contains exactly two weights that work together as a simple upgrade. The kit supports quick changes between rounds or spots on the practice range, letting you compare how different weights influence your swing dynamics.

• Two weights in one package for fast, seamless adjustments
• Available in multiple gram options to tailor launch and stability

Compatibility and installation

These weights are designed for Mizuno ST-Z 220 and ST-X 220 drivers. To install, remove the existing weight, insert the new weights into the port, and tighten until snug. The process is straightforward and can be completed without special tools.

Real-life use cases you might experience

On courses with varying wind or turf conditions, adding weight can subtly alter the ball flight and feel. The 16g and 20g pairing offers a balanced starting point to test whether you prefer a higher launch with more stability or a smoother, more controlled feel.

Cue for quality and care

Crafted for durability with a clean, secure fit, this weight set is built to withstand regular use on the range and on course. Proper seating reduces movement during impact and helps you assess consistent feedback from your swing.

Pro tips for testing your setup

Begin with the 16g plus 20g combination, then swap in other available weights to compare results. Maintain consistent practice conditions to identify meaningful differences in flight and dispersion.

Note that results can vary by swing style and course conditions, so treat this kit as a flexible tool for exploration rather than a guarantee. The goal is to find a setup that feels natural and repeatable for you.

By focusing on feel, you can better align your practice outcomes with on course performance. Keep a simple log of the weights tried and the observed results to track what works best over time.
