Engineered for Speed. Built for Precision.
The Jupiter Lite is the latest innovation from Steadfast Golf, developed in collaboration with shaft designer Steve Sacks. Designed for golfers who want more speed, better launch, and tighter dispersion, without sacrificing feel.
With a lightweight design using high modulus carbon fiber, the Jupiter Lite is 10 grams lighter than previous models—helping you swing faster and hit it farther with less effort.
A softened tip section improves responsiveness and launch angle, giving you higher ball flight and better carry. The balanced weight profile promotes a smooth swing and increased stability at impact.
Available Flexes: Senior (A), Regular (R), Stiff (S), Extra Stiff (X)

Fantastic shaft light, lively, and easy to square up. My 3 wood has become one of my go-to clubs off the tee now.
I wasn’t expecting such a big difference, but the Jupiter Lite really delivers. Better launch, more forgiveness, and a super clean feel.
Extra Stiff flex holds up perfectly to my fast swing. Stability is impressive for a shaft this light. Great job by Steadfast.
Feels premium and extremely well-balanced. My mishits stay on line far better than with my old shaft. Love the smooth profile.
The speed increase is real. The shaft loads beautifully and launches the ball high with great carry. Excellent piece of engineering.
