Used Callaway X

1998–2018

The X line was Callaway's volume iron for twenty years, built on the S2H2 hollow hosel that freed weight out of the neck and into the perimeter. Each generation pushed the centre of gravity lower and further back, and most sold in far greater numbers than the tour irons standing beside them.

FAQs

The questions buyers ask most about these clubs.

What's the S2H2 hosel every X iron shares?

A hollow hosel that frees weight out of the neck and into the perimeter — the constant across twenty years of generations, even as the centre of gravity moved lower and further back each time.

What's the difference between the Pro and Tour builds?

Pro Series ran from the X-12 to the X-18, a shorter blade with less offset; Tour replaced it from the X-20 onward, keeping the cavity construction inside a more compact head.

Which X generation was built purely for distance?

X-24 Hot — the last of the numbered irons, with a thinner, hotter face and stronger lofts, and no Pro or Tour head offered alongside it.
