Sets with identical specs

Callaway Quantum Max has the same loft, lie and length on every club it shares with this set, so a single iron from one fills a gap in the other. The head design and stock shaft can differ, so the club may look different from the rest of your set.

Sets with the same lofts

Callaway Elyte has the same factory lofts on every club it shares with this set. A single iron from one can fill a gap in the other at the right loft, though lie, length or head shape may differ, so check the specs.

Other Callaway Quantum irons from 2026

This set has a 29° 7-iron. Callaway also made the Callaway Quantum Max (29° 7-iron) and Callaway Quantum Max Fast (28° 7-iron). Same family and year, but each has its own head and specs, so check the loft before mixing them.
