The PING i540 iron set has factory lofts from 19° to 47° and captured standard lie angles from 60.5° to 64.1°. Loft and lie changes should be fitted from the actual club measurements and ball flight.

Where PING already publishes one of these configurations, use it as the first reference before inventing a random whole set loft change.
PING Color Code lie fitting
The standard lie figures above correspond to PING’s Black Color Code at standard length on current product specifications. PING’s current chart uses ten lie codes from 4° flat to 5° upright.
| Gold | 4° flat |
|---|---|
| Brown | 3° flat |
| Orange | 2° flat |
| Red | 1° flat |
| Black | Standard |
| Blue | 1° upright |
| Green | 2° upright |
| White | 3° upright |
| Silver | 4° upright |
| Maroon | 5° upright |
Use the chart as a fitting reference, not as proof that every used head can be safely bent through the full range.
Where should you check bending first?
The 4i to 5i loft gap is 3° compared with a 4° set median. That tighter spacing is the first place to check for carry overlap.
Should this set be bent stronger?
The 29° 7 iron is already very strong. Further strengthening should solve a real flight or gap problem rather than chase a lower loft number.
As a geometry example, taking the 7 iron from 29° to 28° would make it 1° stronger and reduce effective bounce by roughly 1° from the published 9° baseline. Actual measured results can vary.
Compare the changed club with both neighbours before bending.
Should this set be bent weaker?
Weakening loft adds effective bounce and can increase launch or stopping power when the resulting carry gaps still make sense.
Lie angle: flatter or more upright?
| Right handed shots start left with centred strike | Investigate a flatter lie. |
|---|---|
| Right handed shots start right with centred strike | Investigate a more upright lie. |
| Left handed golfer | Reverse the left and right directional interpretation. |
| Only one iron is wrong | Measure that club before changing the entire set. |
Can you bend just one iron?
Yes. If the unusual loft gap identified above also produces the wrong carry gap, changing one measured club is usually more targeted than shifting the whole set.
Used PING irons: read the dot, then measure
The dot identifies the club’s intended PING lie code, but it does not prove a used iron still measures there. Previous repair work, bending and changes to PING’s historical Color Code system make actual measurement more important than the paint alone.
Best fitting workflow for this set
- Measure current loft and lie for every problem club.
- Compare actual carry, peak height and start direction with the factory spacing.
- Use loft for gapping or flight problems and lie for directional fit problems.
- Start with the smallest useful change.
- Re-measure after adjustment and re-test against neighbouring clubs.
When not to bend
- The goal is only to copy another model’s printed lofts.
- The problem is strike, shaft length or swingweight instead of loft or lie.
- The requested change would make an already tight gap even tighter without a carry reason.
- The hosel is damaged or has been repeatedly adjusted.
- The exact head has not been confirmed safe for the requested amount.
Disclaimer: PING iron bendability and repair options vary by model, material, age and condition. Color Code systems also changed over time. Have a qualified fitter measure the actual club and confirm the requested adjustment with PING before bending.
