PING’s i540 irons are considered a players distance iron, featuring stronger lofts, tungsten weighting, and an internal air pocket that provides a more pleasing sound and feel than previous models. The i540 has the aesthetic of a players iron while offering big distance gains and forgiveness for the golfer who could use a bit more juice in their game. Since the lofts are mega strong (see the specs below), I chose to go with a 6-iron through Gap Wedge (PING calls it a U-Wedge) for this review. For reference, the 6-iron is 25.5 degrees of loft, so my next club up is actually a 4 hybrid at 20 degrees. The PW is a stout 42 degrees!
During my annual conversations with PING’s Lead Design Engineer Travis Milleman at each year’s PGA Show, we go down the rabbit hole with him on the new equipment coming out – the innovation, materials, specs, and perhaps most importantly, the thought process behind the new product lines. PING is a company that is so well respected in the industry on how they conduct their business and for how they execute delivering high-quality products – this is not the case of all the big OEMs. If you think that’s some media spin or marketing bullshit… just ask any reputable club fitter and/or club builder about what they think of each of the large OEMs, and universally, they’ll tell you that PING (and the Solheim family) are at the very best in terms of quality control and being straight shooters about the capabilities of each product.
So back to our conversations with Milleman, after we discussed the new G440 “K” driver, we delved into irons. Somewhere in the rundown, he handed me an i540 iron and began to tell me about all of the features and properties associated with these new sticks. First off, they look like a better player’s club, but they’re loaded with so much tech “under the hood” that’s the secret sauce that makes these so much easier to launch than your typical better players iron. A players distance iron that look good enough for a scratch player to have in their bag.
Tech Features:
Maraging Steel Face: Features a 9% thinner, forged variable-thickness face that flexes more at impact for faster ball speeds, even on off-center hits.
INR-Air Technology: A patent-pending internal TPU air pocket behind the face dampens unwanted harsh, loud frequencies to provide an upgraded, softer feel.
I-Beam Structure: Adds structural support to the 17-4 stainless steel body to maintain stability across the face.
Tungsten Weighting: Positions weight low in the sole of the 4-7 irons to significantly lower the center of gravity (CG), which encourages a higher, stopping launch angle.
Stock shafts include – PING Alta Blue, PING AWT 3.0, True Temper Dynamic Gold mid-100, KBS Tour, Nippon Modus
Testing:
Aesthetically, better players want to see a slim top line at address, and although it has a ton of tech under the hood, the i540 looks like a legit club that low-digit golfers want to see next to the golf ball… featuring a clean and slim topline.
The sound/feel of the i540 irons is that of a hollowbody construction (only the face of the i540 is forged), but we found the feel to be more pleasing to similar models of like construction – thanks in part to PING’s INR-Air technology inside the cavity of each iron. Impact out of the center feels crisp and a bit lively off the face, almost hybrid-like. Mishits sound and feel as you might expect, a bit louder than ideal, but nothing harsh. If you’ve played anything other than a hollow-body iron recently, it takes a bit of time to get used to the feel of these… but the increase in ball speed is real, and even on mishits.
Perhaps the big question is whether the distance and forgiveness make up for the difference in feel? There’s no question these can help the middle and higher handicap player, so that’s the target demographic. PING isn’t marketing these to low-digit players that play buttery forged musclebacks and blades, but a legit case could be made that they should.
Full disclosure, I’m one of those who has been playing a combo set of forged muscle-back irons for 13 years, so when I began sampling this set of i540 irons, I had no thoughts of gaming them, but I’m an aging GenX player with a 1.3 index clinging to whatever speed I still have on a good day when the body cooperates. Late last year, I decided to park the egoand look into some equipment changes… the first move was to ditch the 3 wood and acquire a Mini Driver; that alone changed my game off the tee dramatically. So in 2026, the approach game has been the focus… would the i540 set have a chance to replace my longtime forged gamers? To be fair, that wasn’t the initial thought when they arrived.
With lofts as strong as these are (see the specs above), I wasn’t sure what to expect. My first swing with the 7-iron on GC Quad flew 176 yards, for a 184 total! Yes, it has 29 degrees in loft… but 184 yards? A typical PW in today’s sets is 45-46 degrees; the i540 is 42 degrees.
Mishits retain their ball speed, and although the i540 irons are a bit on the low spin side (which seems like a detractor for holding shots on firm greens), but PING counters this with launch and descent angle. So although the 7 iron spin rate for me was only 4900, the peak height and descent angle both jumped 15% from my previous set of forged gamers. All while picking up an average of 14 yards of carry per iron. Indoors, the biggest challenge was hitting varying shot shapes and trajectories. The i540 irons wants to go high and straight, unlike my slightly smaller, less-offset forged set that is more prone to hit curves. So, I decided the only way to really find out was to put them in my bag for 30 days, no launch monitors, just golf. And we started at Bandon Dunes (with an LA double-dip of Riviera and Bel-Air thrown in for good measure), just a good fashioned exam of feel and execution.
Rounds at Sheep Ranch, Bandon Trails, Old Mac, Preserve, Riv, Bel-Air and back to the OG at Bandon gave me the full breath of what these i540’s could do. It only took a range session on real turf, and 9 holes on Sheep Ranch for me to realize my misses were better (longer, straighter), and my well-struck shots were still delivering satisfying results. In the wind, off tight fine fescue the i540 allowed me to hit any shot I wanted. The biggest issue I had was getting used to the new yardages, and playing partial shots, but by the third round I began to dial in those elements as well. I’ve taken another golf trip out west since, and have been back playing at home the past 30 days, and the i540 irons haven’t left the bag. Because of the stronger lofts, our longest iron is a 6 (25.5 degrees), so I added a U wedge (47 degrees) for gapping purposes, and removed a hybrid.
In conclusion, whether you fancy yourself as a competitive low-digit shot maker, or a mid to high handicap player striving to improve, the game brings more enjoyment when it’s more fun, and less of a chore. The i540 irons make the game more fun.
The i540 is available from 4i thru U wedge for $1499. For more info – https://ping.com/en-us
