Project X Red 100g 5.5 Flex Steel Iron Shafts - .355 Tip

Project X Red 100g 5.5 Flex Steel Iron Shafts

Project X Red 100g 5.5 Flex Steel Iron Shafts deliver tour-level feel with added height and spin for players seeking maximum playability and stopping power. Designed to build on the legendary control of the original Project X, the Red series offers a higher launch and increased spin profile — all while maintaining tight dispersion and solid stability through the swing. The 100g weight and 5.5 flex combination is ideal for players with moderate swing speeds who want help elevating the ball without sacrificing accuracy.

Tempo

Tempo is about how you transition from backswing to downswing. Project X Red 5.5 is optimized for players with a moderately fast tempo — those who transition quickly but with control. The shaft’s stability and responsive feel help players time the release and maintain confidence through impact.

Trajectory

With a medium launch profile, this shaft helps players generate a high enough flight to hold greens while keeping the ball from ballooning. It’s perfect for golfers looking to improve carry distance and descent angles on approach shots, especially with mid- to long irons.

Spin

The 100g 5.5 flex in the Project X Red series offers medium spin — balanced to give players additional stopping power on the green without losing rollout consistency. It suits players who prefer a bit more control on soft landings and approach shots from distance.
