Jupiter Lite 9 Wood

Engineered for Speed. Built for Precision. Now for Your Fairway Woods. The Jupiter Lite Fairway Shaft is the latest innovation from Steadfast Golf, developed in collaboration with shaft designer Steve Sacks—now optimized for fairway woods. It’s built for golfers who want more speed, higher launch, and tighter dispersion off the deck and off the tee—without sacrificing feel. Designed with a lightweight profile using high modulus carbon fiber, the Jupiter Lite Fairway Shaft is 10 grams lighter than previous models—helping you swing your fairway woods faster and generate more distance with less effort. A softened tip section improves responsiveness and optimizes launch, giving you higher ball flight and better carry from fairway lies. The balanced weight profile promotes a smooth swing and enhanced stability at impact, so you can hit straighter, more consistent shots.
