Speed, distance and control in a player's design. The PING i540 irons represent the modern players distance category — combining the compact look of a player's iron with technology engineered for maximum ball speed and distance. For golfers seeking more speed and distance with stopping power, the i540 is packed with score-lowering innovations for consistent, predictable shot-making. Tungsten weighting and a faster forged maraging steel face help you fly the ball higher and farther, stopping it close. A patent-pending INR-Air™ technology improves sound and feel within the multi-material construction. The result is an iron that delivers exceptional distance and trajectory control without asking you to compromise on workability or aesthetics. Available 4–9, PW, UW.
Ideal for:
The forged maraging steel face features a variable thickness profile that is thinner in key areas, allowing greater flex at impact. This engineered flexibility produces a metal-wood-like bend through the hitting zone, translating directly into elevated ball speed across the face. The result is maximum height on every iron in the set and consistently longer distances — even on slightly off-centre strikes. The face material's superior strength-to-weight ratio also enabled PING's engineers to redistribute mass more strategically throughout the head.
This patent-pending innovation places a precisely engineered air pocket directly behind the face, inside the cavity of the iron. The air chamber selectively dampens specific vibration frequencies that contribute to harsh sound and unwanted feedback at impact. Critically, the air pocket achieves this acoustic and feel benefit without restricting the movement of the face — preserving the full ball-speed benefit of the thin maraging steel construction. The combined effect is a softer, more refined sensation at impact and a tour-quality sound profile across all irons in the set.
Weight savings achieved through the multi-material design allowed PING engineers to place tungsten weights along the sole of irons 4 through 7. Tungsten's exceptional density means a relatively small amount of material moves the centre of gravity significantly lower and deeper compared with conventional stainless steel construction. This lower CG produces a higher launch angle, helping mid-to-long irons carry farther and land steeper for more effective stopping power on approach shots. The strategic sole placement also maintains the compact, clean profile of the head at address — golfers see a player's iron, not a game-improvement club.
The i540's cavity features a structural crossbar — the I-Beam — that spans the interior of the 17-4 stainless steel body, borrowing a principle used in metal-wood construction. This bar reinforces the structural integrity of the body, preventing unwanted flexing that could degrade consistency at impact. At the same time, the I-Beam's geometry is tuned to contribute positively to the overall sound and feel of the club, complementing the work done by the INR-Air technology. The combination of these two innovations inside the cavity delivers a cohesive, refined experience across every iron number.
Every dimension of the i540 head has been shaped to project confidence and inspire precision at address. The compact head size, narrow sole width and thin topline deliver the visual appeal that better players demand, while still housing all the distance-enhancing technology within. The tighter profile supports a higher degree of workability — golfers can shape shots both ways and control trajectory with ease. The clean aesthetic also extends to address position, where the 7-iron sits flat and square, reinforcing alignment and setup consistency before every swing.
The i540 is offered with two graphite stock shaft options to match different swing profiles. The PING Alta CB Blue is a lightweight, counter-balanced graphite shaft designed to produce a mid-high to high launch angle with smooth tempo — ideal for players wanting an effortless feel and a higher ball flight. The UST Mamiya Recoil DART graphite shaft offers a slightly firmer, more responsive profile with medium launch and stable spin rates, suiting players who want graphite's weight benefit without giving up feedback and control. Both shaft families are available in multiple flex options to cover a wide range of swing speeds.

These are design specifications that may vary due to manufacturing tolerances. Lie angle is based on the Black Colour Code at standard length. Club bounce angles will vary slightly if ordered with non-standard loft specifications. Standard swingweights for graphite-shafted clubs are 2 to 3 points lighter than the values shown, depending on shaft flex. Achievable swingweights depend on the shaft and grip combination selected. Available for both right-handed and left-handed players. Shaft weights listed are based on the trimmed length of a 7-iron and may differ from shaft manufacturer website specifications.
