These 2024 irons recorded the fastest ball speeds during robot testing

Callaway's Paradym Ai Smoke impressed in the ball speed department.

Jonathan Wall/GOLF

Unless you’re an elite ball-striker wielding a set of musclebacks that absolutely have to hit a certain speed threshold, adding some velocity through the bag is generally a good thing.

More speed means more distance, and more distance means a shorter club in your hands on a 150-yard approach. That’s a scenario every golfer wants to encounter during a round.

Tracking down an iron with plenty of ball speed in the tank is one way to shorten those approaches. But it’s not just speed out of the middle. Unless you possess a tour card, it’s generally good to have something in the bag that generates strong ball speed numbers across the entire face.

As expected, the five fastest models were in the game-improvement category, which makes sense considering these offerings are usually loaded with ultra-thin faces, tungsten weighting and high-tech cavity badges. Let’s check out the numbers.

(How we calculate: Each 7-iron is tested at 80 mph using three-point face mapping. We hit six balls from each location on the face — heel, toe and geometric center — and then came up with an average based on the 18 strikes.)

Cleveland ZipCore XL | 116 mph

Cleveland ZipCore XL Custom Irons

$128.57
Go big and get it close? Yes, please. With all-new ZipCore XL Irons, you get both. AI-designed MainFrame faces and weighting, along with our legendary ZipCore technology, combine to deliver all of the power, control, and confidence you need to hit it far and stick it close without fail. MAINFRAME Designed with the help of AI, MainFrame uses a variable network of grooves, channels, and cavities milled into the backside of the club face on ZipCore XL’s 4i–7i. This pattern helps maximize flex at impact for better COR. ZIPCORE In 8i–SW lofts, ZipCore replaces heavy steel in the hosel and heel with an extremely lightweight yet strong, vibration dampening material. This sets the Center of Gravity right where you strike the ball, giving you more consistent launch, spin, and distance.

Ping G730 | 115.5 mph

PING G730 Custom Irons

$170
Maximizing distance was the primary objective in PING’s longest and most forgiving iron to date, generating typical distance gains of approximately five yards from the flexing, hyper 17-4 stainless steel face. Flexing Face By employing hyper 17-4 stainless steel through heat treating, we thinned the face and optimized its overall structure to increase flexing and help lower the CG, delivering higher-launching shots with ball-speed gains and approximately five more yards of distance. Powerful Sound The cavity-back design is supplemented with the proven PurFlex cavity badge that enhances feel and produces a more powerful sound. Extreme Forgiveness The bigger head, more offset and wider sole in the investment-cast design increase the MOI in both axes, elevating forgiveness for improved stability and accuracy in this premium game-improvement design.
