Adjusting Your Callaway Paradym Driver
The Callaway Paradym driver uses the OptiFit hosel (8 positions, ±2° loft) and a removable sole weight (2g/5g/7g/9g) to change launch, spin, and shot shape. To adjust: turn the hosel ring to the desired setting, swap the sole weight, and torque both screws to 40 in-lbs with a T25 Torx bit. Do all changes off the course – you’ll need a torque wrench.
If you don’t own a torque wrench, take the driver to a pro shop. Most will adjust it for free. Never use a regular screwdriver or Allen key.
Quick Settings Chart
The OptiFit ring has 8 positions. The N (neutral) marked with a dot is the standard loft (9°, 10.5°, or 12°). The “D” (Draw) setting closes the face angle; it does not move the CG.
| Position | Loft Change | Lie / Face Angle |
|---|---|---|
| N – (dot) | Standard loft | Neutral lie, square face |
| N+1 or D+1 | +1° | Slightly upright lie, +2° closed face (draw bias) |
| N+2 or D+2 | +2° | More upright lie, +4° closed face (strong draw) |
| N-1 | –1° | Neutral lie, –1° open face (slight fade) |
| N-2 | –2° | Neutral lie, –2° open face (fade) |
| D | Standard loft | +2° closed face (draw bias) |
| D+1 | +1° | Same as N+1 |
| D+2 | +2° | Same as N+2 |
Key difference: The D settings close the face without changing loft. N+1 closes the face and adds loft. Choose based on whether you want a draw with higher launch (N+1/D+1) or a flat draw (D).
Step-by-Step Adjustment
- Remove the sole weight – use a T25 Torx bit and torque wrench. Set the screw aside.
- Remove the driver head – unscrew the shaft screw (also T25). Keep both screws in a safe spot (a small cup works).
- Rotate the OptiFit ring to your desired position. The marking must align with the white line on the adapter. You’ll hear a click when it’s seated.
- Reattach the head – slide it onto the shaft until the ring clicks fully. Do not force it.
- Reinstall the shaft screw – tighten to exactly 40 in-lbs (4.5 Nm). If you don’t have a torque wrench, stop now and go to a pro shop.
- Install the new sole weight – insert the weight (2g, 5g, 7g, or 9g) and tighten to 40 in-lbs.
- Test on the range – hit 5–10 balls. If ball flight is still off, try a different weight or a ±1° hosel change.
Branch after step 7: If you see no change in flight after two adjustments (e.g., still slicing with a D setting), the problem may be swing path or face impact location, not the equipment. Go back to neutral (N) and check your alignment and grip first. If you’re still unsure, book a clubfitting session.
Stop/escalate threshold: If the shaft screw or sole weight screw won’t turn smoothly, feels stripped, or the head wobbles after tightening, stop immediately. Do not play with a loose head – it can fly off mid-swing. Take it to a certified Callaway repair center. Attempting to force a stripped screw can damage the threaded aluminum port beyond repair.
Common Settings (Draw/Fade/High/Low)
For a Draw (right-to-left for right-handed):
– Hosel: D+1 or D+2 (closed face, adds loft)
– Sole weight: 2g or 5g (lighter weight helps square the face earlier)
– Result: Higher launch + draw bias
For a Fade (left-to-right):
– Hosel: N-1 or N-2 (open face, reduces loft)
– Sole weight: 7g or 9g (heavier weight slows face closure)
– Result: Lower launch + open face angle
For Higher Launch:
– Hosel: N+1 or N+2 (adds loft)
– Sole weight: 2g or 5g (moves CG back, increases launch)
– Result: Steeper descent angle, more carry
For Lower Launch / Lower Spin:
– Hosel: N-1 or N-2 (reduces loft)
– Sole weight: 7g or 9g (moves CG forward, reduces spin)
– Result: Flatter trajectory, more roll
Practical note: Changing loft ±2° also changes effective face angle. At N-2 the face is 2° open – aim slightly left to compensate. At D+2 the face is 4° closed – aim right.
Torque & Tools
Torque spec: 40 in-lbs (4.5 Nm) for both screws.
Required tool: T25 Torx bit + torque wrench (available at most golf retailers or online).
Never use an Allen key, a hex bit, or a hand‑tighten approach. The Paradym driver head uses aluminum threads – overtightening strips them (warranty void). Undertightening lets the head loosen during a swing.
Common mistake: People crank the shaft screw “hand tight” with a standard driver, then wonder why the head feels loose after a few swings. Always torque it. If you don’t have a wrench, use a pro shop’s for free.
FAQ
Can I adjust the driver on the course?
No – you need a torque wrench and T25 bit. All changes should be done at home or on the practice range.
Does changing the hosel move the CG?
No. The OptiFit only changes loft and face angle. The center of gravity stays fixed. Only the sole weight shifts CG: heavier weight moves it forward (less spin), lighter weight moves it back (more spin).
What if my Paradym has a sliding weight track (like older models)?
The standard Paradym, Paradym X, and Triple Diamond all use a screw‑in weight port. No sliding track. If your driver has a track, it’s not a Paradym – check the model.
Will adding +2° loft make the driver illegal?
No. The USGA allows up to 2° of adjustable loft. A 9° head at +2° becomes 11°, well within limits. For tournament play, verify locally if your local rules have tighter restrictions.
How do I choose the right sole weight?
Start with the weight that came in the driver (often 7g for standard models). If you want a softer, higher landing, try 2g or 5g. For a more boring flight, try 9g. Change only one variable at a time – weight or hosel – so you can isolate the effect.
Can I use aftermarket weights?
Only use genuine Callaway Paradym weights. Aftermarket weights may have slightly different thread pitch or length, risking cross‑threading or loosening. Stock weights are available from Callaway or authorized dealers.
When should I stop DIY adjustments?
If the screw won’t tighten to 40 in-lbs (it keeps turning), feels gritty, or the head wobbles after torquing, stop. Do not play. Take it to a certified repair center or Callaway service. A loose head can damage the shaft and the head, and flying parts can cause injury.
