Collection: Callaway Big Bertha Alpha 815 & 816 Driver Shafts – Fully Compatible Upgrade Options
Upgrade or replace the shaft in your Callaway Big Bertha Alpha driver — whether 815 or 816 — with our premium selection of aftermarket shafts. Each shaft listed here is fully compatible with the Alpha 815 and Alpha 816 driver heads, and supplied adapter-ready (when applicable) for correct fitment and immediate performance gains.
The Big Bertha Alpha 815 and 816 drivers are well known for combining adjustability, forgiveness, and low-spin distance potential. With features like the adjustable gravity-core weight system and R•MOTO face design, these heads offer launch/spin customisation and solid ball-speed — but pairing them with a modern, well-matched shaft can unlock even greater performance. A shaft upgrade can improve launch angle, spin control, ball-speed consistency, and shot dispersion — especially helpful if you’re seeking more carry, tighter grouping, or better control from your tee shots.
Our shaft range includes options from leading manufacturers — Fujikura, Mitsubishi Chemical, Graphite Design, Aldila, Project X and more. We offer a broad selection of shaft weights, flexes and launch/spin profiles, from lighter, high-launch shafts to firm, low-spin shafts for stronger swings. This variety allows you to fine-tune the Alpha head to your swing speed, ball flight preference, and playing conditions.
All Big Bertha Alpha-compatible shafts listed here are in stock, professionally assembled in our UK workshop, and dispatched quickly for prompt delivery.
