Our readers are always interested in hearing about the new shafts we spot on the ranges of the PGA Tour, but interest really spikes when we spot a new model that shares its name with a classic. At the Wells Fargo Championship we did just that, snapping photos of True Temper’s new Project X LZ steel iron shafts.

True Temper currently offers Project X LZ Handcrafted graphite shafts for drivers and fairway woods, which have a “Loading Zone” located in a different area of the shaft depending on flex to help golfers transfer more energy to the golf ball at impact. With the Project X LZ iron shafts, it looks as though True Temper is after the same result, while keeping the penetrating trajectory and overall stability for which Project X iron shafts are known.

The LZ technology is visible through what True Temper calls “rapid, tapered steps out of the grip through the midsection.”

The tapered steps, or “LZ” technology, were not used in either the Project X or PXi shafts.

Project X LZ vs. Project X

According to True Temper, the butt and tip sections of the new Project X LZ iron shaft were made stiffer than the original Project X design, however, the midsection of the shaft has a reduced stiffness to accommodate the “LZ” design.

The Project X LZ iron shafts are also lighter than the original model, but heavier than Project X’s PXi shaft, which is currently used by several players on the PGA Tour including Jason Dufner and Ian Poulter.

Keep in mind that the original Project X iron shaft is the brand’s most popular shaft on the PGA Tour, and can boast usage by World No. 1 Rory McIlroy (Project X 7.0 in irons, Project X 6.5 in wedges), Master’s champion Jordan Spieth (Project X 6.0 in irons and wedges), and Gary Woodland (Project X 7.0 in irons, Project X 6.5 in wedges), who is considered the longest hitter on the PGA Tour by his peers.
