Adjusting The Loft Angle of a Mizuno JPX One Driver
There are a few simple steps you can take to adjust the loft angle of your driver. You will just need an adjustment tool or wrench to get started.
Here’s how to adjust a Mizuno JPX One driver:
1. Locate the screw on the sole of your Mizuno JPX One driver that attaches the driver head to the shaft.
2. Using the wrench, loosen the screw by turning anticlockwise.
3. Once the screw is fully out, you can rotate the adjustable hosel to a lower loft or a higher loft depending on your preference. You will notice the loft settings you had the driver set to and be able to turn the shaft to up to 16 further options.
The settings on a Mizuno hosel mean the following:
- STD – Standard loft, standard lie. This is the neutral factory setting
- LOW – Standard lie, loft reduced by about 2° from stated. This also opens the face slightly and lowers launch/spin
- HIGH – Standard lie, loft increased by about 2°. This closes the face slightly and raises launch/spin
- U / UPRIGHT – Same loft as STD, but lie angle about 2-3° more upright to encourage a more draw‑biased starting line
- +1 – Loft increased by 1° from stated, lie close to standard
- +2 – Loft increased by 2° from stated, lie close to standard
- -1 – Loft reduced by 1° from stated, lie close to standard
- -2 – Loft reduced by 2° from stated, lie close to standard
4. When you have turned the hosel to your required loft, slot the shaft back into your club head. Your new loft will be display through the window on most drivers.
5. Put the screw back in place and tighten with the wrench by turning clockwise. When it is fully tight, you will hear a crank that sounds like the driver is cracking. At this point, the screw is as tight as needed.
Every time you want to adjust the loft, you repeat this process.
