Jupiter Lite Driver Shaft

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.
