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.
