Mitsubishi MMT Iron Shaft .370


The Mitsubishi MMT Iron Shaft .370

Mitsubishi's patent-pending Metal Mesh Technology combines the power of composite & steel performance for maximum benefits. The core of the shaft is crafted with layers of prepreg, with a small section of Metal Mesh towards the tip. This unique Mesh - 304 Stainless Steel braided into individual strands - increases stability & density, while allowing for a thinner composite wall construction. All of this combines to create a finely tuned, responsive shaft that offers an optimal launch & spin for improved iron play.

Product information


What happens if I can’t select the combination of head, shaft & grip I want?

Email us on or call 020 3995 5638 we would be more than happy to discuss and prepare a custom quote.

I am purchasing from outside of the UK, what happens with TAX / Customs duty?

All orders show and charge TAX / Duties at checkout so there will be no additional payment required to the courier. Goods will be delivered duties paid (DDP)

Do you offer advice prior to purchase if I am unsure which product to choose?

We understand and recommend trying / having a fitting prior to any purchase but should this not be possible our team will be more than happy to help you through any purchase. Either via email or on the phone.

I paid for Express shipping on a custom order, why hasn't it shipped next day? 

Express shipping is the fastest possible shipping service, unfortunately it is not a way of getting your custom order built faster.

What if I can’t find an option I want on a drop-down menu?

If you can’t find a grip or shaft that you would like to order then please do reach out to us or place an order and leave a note on the order. One of our team will be happy to help you through the process.
