Updated November 2026

Parents shopping for a cobra fly z junior driver usually need one thing first: the right replacement or add-on weight for the clubhead. The Fly-Z family uses small screw-in weights to adjust swing weight and feel, and the weight that fits best depends on your child’s height, grip strength and swing speed. This list focuses on four weight options built for the Fly-Z head, judged by fit with the Fly-Z series, weight variety, packaging and owner feedback patterns.

Buying Guide

Check the head compatibility

Confirm that the weight is listed for your specific Fly-Z model, since the screw-in weight port must match. Look for the exact model names in the listing.

Match weight to swing speed

Heavier weights add stability but can slow swing speed for smaller golfers. Lighter weights are easier to swing but may feel less stable on off-center hits.

Change one variable at a time

When testing weights, swap only one piece and observe the results over several sessions before making another change.

Consider a full upgrade when the fit is off

If your child needs a different length, loft or shaft flex, a weight swap won’t solve the problem. A complete driver may be the better step.

FAQ

Can a weight change the flight of a Fly-Z junior driver?

Yes, a heavier or lighter weight shifts the balance point and can change feel and launch tendencies. Results vary by swing, so test gradually.

Do I need the same weight on both sides?

Most Fly-Z setups use a single weight in a designated port. Check your club’s manual for the correct placement before adding or removing weight.

When should a junior golfer move to a full driver?

When the current club no longer fits height, grip size or swing speed, a complete driver with new specs is usually the better step.

Conclusion

For a simple replacement, the XFDACOV 11g weight is a sensible middle option. Choose the HISTAR 13g for a heavier feel and the DAZUZ 7g for light fine tuning. If your child has outgrown the Fly-Z, the Cobra Darkspeed Adapt MAX-K Driver is the step up.
