About the XXIO Prime
Prime is the top of XXIO's range and the lightest thing the brand builds — the stock SP-1300 iron shafts weigh 42 to 46 grams, and the set runs at C7 swing weight. The head is a four-piece construction with a titanium face and a Rebound Frame structure for a very low centre of gravity. The stock set starts at the 6-iron; the 5-iron is special order. Lofts match the XXIO numbered sets club for club.

Frequently asked questions
What is the loft of an XXIO Prime 7-iron?
The XXIO Prime 7-iron has a loft of 28 degrees, a lie of 62.5 degrees and a length of 37.5 inches.
Why does the XXIO Prime set start at the 6-iron?
That is the stock makeup — 6-iron through sand wedge. The 5-iron is available on special order rather than as part of the standard set.
How light is the XXIO Prime iron shaft?
The stock SP-1300 graphite iron shafts weigh between 42 and 46 grams, which is roughly a third of a typical steel iron shaft, and the finished clubs measure C7 swing weight.
Where it sits in the lineup
Introduced in 2025, the XXIO Prime is a current super game improvement set in the XXIO range as of September 2026, with no replacement announced. New sets are built to the standard lofts, lies and lengths in the chart above, though a fitting can move any of them — so confirm the numbers on the order sheet. Used sets appear on eBay, and should be measured against this chart before buying.
- XXIO's own Prime irons product page, specification table (srixonasia.com) — supplied every loft, lie, length and swing weight, the SP-1300 stock shaft weights and flexes, and the note that the stock set is 6-iron through sand wedge with the 5-iron on special order.
- firstcallgolf.com 'XXIO Brings Beauty, Vitality and Strength to All-New Prime' and the matching Dunlop Sports release — announced 10 March 2025, US retail 14 March 2025, four-piece titanium-face construction with the Rebound Frame.
- Note: this file records the Prime generation launched in March 2025. XXIO has sold Prime clubs under the same name since 2005, so a Prime set bought earlier will not match this chart.
- Status check, 29 September 2026: confirmed as a current model with no replacement announced. Product page live and in stock on XXIO's US site (us.dunlopsports.com).
