Explore Quantum Max, Quantum Max Fast, and Quantum Max OS Irons to find the model that helps you launch it higher, carry it farther, and hit more greens.
What's the difference between the Quantum Max and Quantum Max OS Irons?
The Quantum Max OS (Oversized) Irons are the most forgiving in the Quantum lineup, with a larger head profile and maximum game-improvement shaping. The Quantum Max is slightly more compact while still delivering strong forgiveness and ball speed for a wide range of players. If maximizing forgiveness and launch are your top priorities, the Max OS is the better fit.
What's the difference between the Quantum Max and Quantum Max Fast Irons?
The Quantum Max Fast Irons are engineered for golfers with moderate swing speeds who need help generating distance throughout the set. The lighter construction promotes faster club speed, more ball speed, and higher launch for better carry distances across all irons. The Quantum Max is the all-around game-improvement option for players who want strong performance across a broader range of swing profiles.
What is Callaway's Modern 360 Undercut?
The Modern 360 Undercut is a cavity design in Quantum irons that adds low face flexure, where golfers need it most, promoting faster ball speeds and a higher launch at impact. By allowing the face to flex more efficiently at contact, it delivers better distance and trajectory across a wider range of strikes. It's one of the core technologies behind the Quantum iron lineup's speed and forgiveness.
How do I choose the right Quantum Irons for my game?
Match the model to your swing speed and goals: Quantum Max OS (maximum forgiveness for the most help on mis-hits), Quantum Max (balanced game improvement), Quantum Max Fast (lighter build for moderate swing speeds). Quantum also offers recommended hybrid/iron combo sets for optimized gapping throughout the bag.
Which Quantum Irons are the most forgiving?
The Quantum Max OS is the most forgiving iron in the lineup, combining an oversized head, the Modern 360 Undercut for added face flex, and a Progressive Tri-Sole Design for improved turf interaction. If you want to maximize distance and consistency on off-center hits, the Max OS delivers the highest level of game-improvement support in the Quantum family.
