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, 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, 2nd Swing and Golf Avenue, and should be measured against this chart before buying.
- XXIO's own Prime irons product page, specification table (https://srixonasia.com/product/xxio-prime-irons/) — 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.
