They’ve grown. So should their gear.
The UpSwing Junior to JV Growth Kit is the perfect next step for players who’ve outgrown their original Junior set and are ready to level up their game. Designed for golfers now standing between 42"–54" tall, this upgrade kit transitions your golfer’s existing clubs into the next performance tier—with pro-level materials and no guesswork.

The kit includes both new JV-sized club shafts and fully assembled clubs to match the UpSwing JV Set. With our easy-to-use shaft swap system, you’ll have your golfer back on the course in minutes—better equipped, better sized, and ready to keep growing their game.

Now available for pre-order. 


When they level up, we make sure their clubs do too.

UpSwing Growth Kits are designed to evolve with your junior golfer—so you never have to start from scratch as they size up. Each kit makes it easy to transition into the next performance tier by combining replacement shafts with pre-assembled clubs that match the next level in the UpSwing lineup.

Thanks to our proprietary system, swapping out club shafts is simple, secure, and hassle-free (just use the torque wrench that came with your original set). In just a few minutes, your golfer is back on the course with clubs that are built for the swing they’ve grown into.

Because real progress deserves real equipment—and we’re here to grow with them.
