FREEFLEX Instinct 2 Series Iron Shafts
The FREEFLEX Instinct 2 Series Iron Shafts bring progressive performance engineering to every part of your iron set. Featuring three precision-tuned models for long (4567), mid (6789), and scoring (PGS) irons, the Instinct 2 shafts deliver ideal launch conditions, forgiveness, and workability exactly where players need it most.
Each shaft is built to a 39" length with a .355" tapered tip, allowing easy installation without tipping. The lighter, softer long iron shafts launch higher and more easily; mid iron shafts provide versatile ball control and consistency; and the firm scoring iron shafts tighten dispersion for precision near the green. Designed for players who demand set optimization and smooth transitions from club to club, the Instinct 2 Series raises the bar for custom fitting flexibility.
- Long Irons (4567): 58g, 235 CPM, 6.5 TQ — optimized for high launch and forgiveness
- Mid Irons (6789): 60g, 245 CPM, 5.5 TQ — balanced for controlled ball flight and versatility
- Scoring Irons (PGS): 65g, 255 CPM, 4.5 TQ — designed for maximum accuracy and low dispersion
- Length: 39" uncut, easy butt trim customization
- Tip Size: .355" tapered — fits most premium iron heads
Choose one shaft profile for your full set or mix and match to optimize launch, spin, and control for each club. FREEFLEX Instinct 2 delivers total performance your irons deserve.
