The Callaway Quantum Max Fast iron set has factory lofts from 22° to 56° and lie angles from 60. Loft and lie may be adjusted by a qualified club fitter, depending on the exact head construction and condition.

model specific bending analysis • 2026
What stands out about the Quantum Max Fast specs?
Gap pattern: The captured loft gaps have a 4° median, with a smallest gap of 3° and a largest gap of 6°. tighter than typical gaps appear at 5i to 6i (3°), 6i to 7i (3°). larger than typical gaps appear at 8i to 9i (5°), 9i to PW (5°), GW to SW (6°).
Lie progression: The captured lie angles progress from 60.75° to 64°, a total increase of 3.25° across the set. The median step between captured clubs is 0.375°.
The long end begins 5i 22°, 6i 25°, 7i 28°, 8i 32°. The scoring end finishes PW 42°, AW 46°, GW 50°, SW 56°. Those two ends do not have to use identical loft spacing because launch, speed and carry compression are different.

Where would I check for bending first?
The GW to SW transition is the first place I would verify on a launch monitor because its 6° loft gap is wider than this set’s 4° median. Also verify peak height and landing angle before making any club stronger.
If that pair also produces an excessive carry gap, a small loft change to one of those two clubs may be more sensible than changing the entire set.
How much bending makes sense for this set?
| Change | How it fits this model |
|---|---|
| 0.5°–1° | Best range to investigate first when one club is creating a small directional or carry gap problem. It is enough to matter without automatically rewriting the set’s factory progression. |
| 1°–2° | A meaningful change. On the Quantum Max Fast, compare the new loft against both neighbouring clubs so you do not create a second gap while fixing the first. |
| More than 2° | Large enough that bounce, offset and gapping consequences become substantial. Confirm head construction and the exact target with Callaway/a qualified fitter before considering it. |
- 1° strong → about 27° loft and roughly 1° less bounce.
- 2° strong → about 26° loft and roughly 2° less bounce.
- 1° weak → about 29° loft and roughly 1° more bounce.
- 2° weak → about 30° loft and roughly 2° more bounce.
These numbers show the geometry only; they do not mean this exact head is safe to bend by that amount.
Should the Quantum Max Fast be bent stronger?
The 7 iron is 28°, which is very strong by traditional iron standards. Further strengthening should be approached cautiously because it can remove additional bounce and compress the carry gaps.
- Strengthening loft generally lowers static loft, removes roughly the same amount of bounce, and slightly increases offset.
- The GW to SW transition is the first place I would verify on a launch monitor because its 6° loft gap is wider than this set’s 4° median.
- Do not strengthen a club merely because another Callaway iron has a lower printed loft.
Should the Quantum Max Fast be bent weaker?
- Weakening adds loft and approximately the same amount of bounce while slightly reducing offset.
- If a club launches too flat or creates too much carry separation, weakening may help; but compare it with both neighbouring carry numbers first.
- If the set is already in the very strong lofts category, the flight goal matters more than matching a generic loft chart.
How the actual loft gaps affect bending
This set has noticeably varied loft spacing, so a blanket whole set loft change is unlikely to be the smartest first move. Preserve the intentional progression unless launch monitor data shows a systematic problem.
How the actual lie progression affects bending
The captured lie angles progress from 60.75° to 64°, a total increase of 3.25° across the set. The median step between captured clubs is 0.375°. Because the factory lie progression already changes through the set, do not automatically make every iron the same amount upright or flat. A 1° whole set change preserves the progression; individual club changes deliberately alter it.
| right handed player starts shots left with centred strike | Investigate flatter lie on the problem club(s). |
|---|---|
| right handed player starts shots right with centred strike | Investigate more upright lie. |
| left handed player | Reverse the left/right directional interpretation. |
| Only one club misbehaves | Measure that club against the set before applying a whole set lie change. |
Can you bend just one Quantum Max Fast iron?
Yes; and the spec pattern tells you when that may be smarter. The GW to SW transition is the first place I would verify on a launch monitor because its 6° loft gap is wider than this set’s 4° median. If the rest of the set produces good start lines and carry gaps, changing one measured problem club is more targeted than shifting all 9 captured clubs.
Should you bend the whole set?
This set has noticeably varied loft spacing, so a blanket whole set loft change is unlikely to be the smartest first move. Preserve the intentional progression unless launch monitor data shows a systematic problem. For lie angle, a whole set change is more defensible when the same centred-strike start-direction pattern appears from long irons through scoring irons. For loft, whole set changes are rarely necessary just to solve one bad carry gap.
Used Quantum Max Fast irons: measure before copying factory specs
The factory chart is a reference, not proof of what a used club measures today. If the widest or tightest gap in this set also looks wrong on the launch monitor, measure those two clubs first: one may simply have drifted from its intended loft or been bent previously.
What bending changes besides the printed number
| 1° stronger | About 1° less loft, roughly 1° less bounce, slightly more offset, generally lower launch direction. |
|---|---|
| 1° weaker | About 1° more loft, roughly 1° more bounce, slightly less offset, generally higher launch direction. |
| More upright lie | For a right-hander, generally adds leftward start line influence. |
| Flatter lie | For a right-hander, generally adds rightward start line influence. |
Best bending workflow for this specific set
- Measure all captured clubs rather than assuming they still match the factory table.
- Start with the unusual gap(s) identified above, then compare actual carry distance, peak height and landing angle.
- For directional problems, use centred-strike start direction and dynamic lie rather than loft.
- Make the smallest useful change to one problem club first.
- Re-measure it immediately and compare it with both neighbouring clubs.
- Only expand the adjustment to more clubs if the same pattern is genuinely present.
When not to bend the Quantum Max Fast
- The requested change is only intended to copy another model’s loft numbers.
- The club’s poor result is caused by strike, shaft length, swingweight or delivery instead of loft/lie.
- The change would make an already tight factory loft gap even tighter without a carry-distance reason.
- The hosel shows prior stress, finish damage or evidence of repeated bending.
- The exact head construction has not been confirmed safe for the requested amount.
Disclaimer: Iron bendability varies with head construction, hosel design, finish, age, previous bending and condition. Do not assume a universal safe adjustment such as ±2°. Have a qualified club fitter measure the actual club and confirm the permitted adjustment with Callaway for your exact model before bending.
