Mizuno Quick Switch Driver Shaft Adapter (.335) – JPX One, ST-MAX, ST-G, & Previous

Mizuno has used the same Quick Switch driver hosel across a long run of models, so a single adapter spec covers the current JPX One and ST-MAX 230 as well as ST-G, ST-X 230, ST-X 230 Platinum, ST-Z 230, the 220-series, ST-Z and ST-X, and back through the ST-200, ST-190, ST-180 and GT-180 generations, plus the JPX-900 and JPX-850 drivers.

That breadth makes this a useful adapter for fitters and club builders working across multiple Mizuno driver generations, since one part number covers most of the modern lineup. See the compatibility table above for the full list.

The Quick Switch system allows up to 4 degrees of loft adjustment and up to 3 degrees of upright lie adjustment. Adjusting loft primarily changes launch angle and spin, while the upright lie settings help golfers who fight a fade or want to encourage a draw bias.

These adjustments let you fine-tune ball flight without changing shafts or heads, and the settings carry over identically when you install a new shaft on this adapter.

No. Although Mizuno drivers and fairway woods both take a .335 tip shaft and both use the Quick Switch system, the driver and fairway wood adapters are different parts and are not interchangeable. Hybrids are different again and use a .370 tip.

We carry all three as separate listings — driver (.335), fairway wood (.335), and hybrid (.370). Make sure you are ordering the one that matches your club type.

Each order quantity of 1 includes one (1) individual shaft adapter in the selected configuration. Product photos may show multiple adapters, installed examples, or different adapter options to illustrate compatibility and installation, but a quantity of one at checkout equals one adapter.

If you need adapters for multiple shafts or different club models, simply adjust the quantity at checkout or add each adapter configuration separately to your cart.

The installation screw is included with this adapter. A ferrule is not included — if your build needs one, we carry ferrules separately.

This adapter is for right-handed clubs only. Left-handed Mizuno heads use a different adapter and this part will not seat correctly in a left-handed hosel.
