Overview

The SK Fiber Hypersonic 0.370-inch graphite shaft is designed to bring a balanced blend of speed, feel, and consistency to iron play. This is a raw, uncut shaft and does not include a shaft adapter or grip, giving you a clean starting point to tailor hardware to your setup. When you pair a chosen grip and compatible adapter, you can tune weight distribution and balance to suit your swing tempo and preferred ball flight. For shops and players exploring options, this shaft offers a flexible foundation without committing to a full replacement kit.

Constructed from high-modulus graphite, the shaft features a 0.370-inch tip diameter, a 5.9-inch parallel section, and a 0.600-inch butt diameter. It measures 41 inches in length with a torque of 3.4 degrees and weighs about 68 grams. The result is a light, responsive feel that can help you maintain rhythm through the swing while delivering a stable impact experience.
