The New Project X LZ Iron Shaft


Until this season, True Temper’s popular Project X iron shaft line consisted of two version: the original Project X shaft, which is currently played by four-time major winner Rory McIlroy, and the lightweight Project X PXi shaft that Ian Poulter and Jason Dufner use.




Both shafts have enjoyed success on TOUR, but over the course of the last year, True Temper started to see the need for a Project X model that fell in between the profiles of PX and PXi.

Enter Project X LZ (Loading Zone), an iron shaft that actually has a similar design to True Temper’s Hand Crafted LZ graphite with a loading zone in the middle of the shaft.


According to Paul Loegering, True Temper’s Tour relations manager, Project X LZ still features the same low-to-mid launch and spin that Project X is known for. However, the new shaft has a butt and tip section that’s actually stiffer than the original PX, allowing for more stability during the downswing with a consistent trajectory and low spin.


The shafts also differ in the midsection. While Project X has a stiff profile throughout, Project X LZ has a softer midsection (micro steps) that acts as a loading zone on the downswing, improving clubhead speed by transferring more energy to the golf ball at impact.


“The loading zone is more of an energy transfer that transitions the energy from the top of the swing to the golf ball to create more clubhead speed,” Loegering said. “Obviously all these guys on TOUR want to get maximum clubhead speed, and this loading zone will help them achieve what they’re looking for.”

Adam Scott recently switched to the Project X LZ 6.5 Iron Shaft and won the Honda Classic and the WGC-Cadillac Championship the following week.


The shaft will be available in five flexes — 5.0, 5.5, 6.0, 6.5 and 7.0 — and increases in five-gram increments, starting with 105 grams in the 5.0 flex to 125 grams in the 7.0 flex.

“This will be a good option for the guys [on TOUR] that want to stay in Project X but need a little bit more spin and don’t want to flight the long irons up ” Loegering said. “It’s going to offer a consistent apex height in the long irons, which is something players expect with Project X.”
