Ping G425 Irons Specs: Loft, Lie Angle & Length Data (Standard/Power/Retro)
All G425 irons share the same head design, but you can order them in three loft configurations. Standard is the baseline; Power Spec is 1.5° stronger per club; Retro Spec is 1.5° weaker. Lengths and lie angles are identical across all three specs. If you already own a set, check the hosel stamp (“P” or “R”) to confirm which variant you have. If you’re shopping, pick one spec for the whole set—mixing within a set creates inconsistent gapping that a fitter can’t easily fix.

| 8i | 34.5° | 33.0° | 36.0° | 62.8° | 36.5″ | ~0.195″ |
| 9i | 39.5° | 38.0° | 41.0° | 63.5° | 36.0″ | ~0.175″ |
| PW | 44.5° | 43.0° | 46.0° | 64.1° | 35.5″ | ~0.155″ |
Lengths are standard steel-shaft lengths. Offsets are approximate; exact values vary slightly per production run. Lie angles are stock; custom fitting is recommended for lie and length adjustments beyond the standard options.
The G425 heads are cast from 17-4 stainless steel with a metal-wood-style face that flexes at impact to boost ball speed, especially on strikes low on the face. A tungsten toe weight adds forgiveness. This technology works the same way regardless of which loft spec you choose.
Key Takeaways
Which spec fits your game depends on launch and distance goals, not skill level alone. Power Spec (stronger lofts) lowers peak height and reduces spin, adding 3–4 yards per club on center hits. Retro Spec (weaker lofts) raises launch and increases spin for steeper descent angles, which helps hold greens. Standard Spec splits the difference. If your current iron set has a 7-iron loft near 34° or higher (common in older or players-style sets), Retro Spec may better match your expected gapping. If you switched from a modern distance-oriented set, Power Spec might feel familiar.
Do not rely solely on the club number printed on the sole. A Power Spec 7-iron (28.5°) is actually stronger than a Standard Spec 6-iron (26.5°). Compare actual lofts—not club numbers—when you blend the G425 into a mixed set or compare distances with your current irons.
Verify your spec before ordering wedges or gap fillers. If you order a G425 PW and a separate G425 gap wedge (often sold as a U wedge in the same series), make sure both are the same loft spec. A Standard PW (44.5°) paired with a Power gap wedge will leave a 2.5° gap between them instead of the intended 4–5° step, creating a yardage hole in your short game.
What can go wrong with a loft change that seems small? A 1.5° stronger loft reduces spin by roughly 500–700 rpm on a 7-iron. If you already launch the ball low or play on firm greens, Power Spec may cause flatter landings and less stopping power. Conversely, Retro Spec may balloon in windy conditions. Test one spec on a launch monitor before committing to a full set.
How to confirm your current set’s spec without a launch monitor: Look for a stamp on the back of the hosel—a small “P” for Power Spec, “R” for Retro Spec. No stamp typically means Standard. If you buy used and the stamp is worn, a clubfitter can measure loft with a digital gauge in about 30 seconds per club.
Limitation to know: Lofts are fixed in the casting. They cannot be bent. If you buy Standard and later want stronger lofts, you must buy a new set in Power Spec. There is no aftermarket adjustment option. Similarly, if you need lie angles flatter or more upright than stock, custom order is required; the hosel construction does not allow easy retrofitting.
Choosing Your Loft Spec
Use these decision rules to narrow the choice before ordering.
- If you need more carry distance without changing swing, Power Spec gives you a direct loft-driven gain. Expect roughly 3–4 extra yards per iron on center hits, but check your descent angle on a monitor. If it drops below 45° with a 7-iron, you may struggle to hold greens.
- If you frequently land shots short of the pin or play on soft greens, Retro Spec raises launch angle and adds spin. That steeper descent helps balls stop quickly. However, you will lose a few yards of raw distance—plan to club up more often.
- If your current 7-iron loft is 30° or higher (typical of older forged irons or cavity backs from the early 2000s), Standard Spec will feel familiar. Power Spec will launch noticeably lower, so only switch if you have the swing speed to still get the ball airborne.
- If you are building a blended set (e.g., G425 long irons with a more compact short iron), match the lofts at the transition club, not the numbers. For example, if you want a 5-iron that gaps to a players-style 6-iron at 30°, you might need the G425 5-iron in Retro Spec (25°) to avoid a 5° gap.
FAQ
What is the difference between Standard, Power, and Retro Spec?
Power Spec reduces the loft by 1.5° per iron, increasing distance but lowering peak height and spin by roughly 500–700 rpm on a middle iron. Retro Spec adds 1.5° of loft, raising launch and spin for steeper landing angles. Standard Spec is the in-between baseline.
Can I change the loft on my existing G425 irons?
No. Lofts are cast into the head and cannot be bent. You would need to order a new set in the desired spec.
Are the G425 irons suitable for low-handicap players?
They are game-improvement irons with moderate offset and a thick sole. Low handicappers who prefer a compact head, thinner topline, and less offset may find the i525 or Blueprint series a better fit. That said, some low-handicap players use G425 irons in the long end for forgiveness and mix them with more workable short irons.
What shaft lengths are available for Power or Retro Spec?
Lengths are identical to Standard Spec for all three configurations. Only lofts change.
Do Power Spec irons comply with USGA/R&A regulations?
Yes. The lofts in Power Spec remain within the USGA’s groove and clubhead rules. Always verify local tournament conditions, but no general restriction applies.
