Steelfiber J88 Iron

Designed to promote higher launch in a lightweight performance package, Steelfiber J-Series iron shafts deliver enhanced playability without sacrificing stability or control. Parallel tip construction provides fitters with expanded versatility, allowing for precise tuning across a wide range of player needs and build specifications.

At the core of each shaft is a high-modulus graphite structure, reinforced with over 59 miles of exclusive Steelfiber material unique to Aerotech. This advanced composite construction creates exceptional hoop strength and structural stability, delivering the consistent feel, control, and performance typically associated with steel while maintaining the vibration-dampening benefits of graphite.

Features

Spin

Spin is the amount of backspin that the ball has. The designs of certain golf shafts can promote more or less spin so keep this in mind when looking for a shaft to maximize your game.

Tempo

Tempo is not how fast you swing it, it is how you swing it fast. Tempo will affect how you load and unload the shaft and is a big factor in which shaft will best suit you. A player with a quicker backswing and more aggressive transition will have a faster tempo, while a player with a slower backswing and smoother transition will have a more deliberate tempo.

Trajectory

Trajectory is the flight of the ball and the peak height that the ball reaches. A player who struggles with getting the ball in the air should look towards a higher trajectory shaft, while a player who struggles hitting the ball too high should look for a lower trajectory shaft.
