If there’s a shaft manufacturer golfers of all abilities have come to trust, it’s True Temper. While the company makes a variety of high-performing shafts, the Project X family is the most recognizable.
In this article, we’re going to take an in-depth look at the Project X LZ Iron Shafts.
These steel iron shafts are suitable for a wide variety of golfers, and have proven to be some of the best feeling iron shafts True Temper has ever made.
Let’s dive a little deeper.
Key Features
Loading Zone Technology maximizes energy transfer on the downswing for explosive ball speeds.
Variable Wall Technology in the butt and tip sections reduces stiffness in the midsection.
Plenty of flex options give players plenty of options to choose from.

Design and Technology
No one utilizes technology in iron shafts better than True Temper.
In the LZ Shafts, it’s all about Loading Zone Technology. While iron shafts all work to load power in the backswing and unload it in the downswing, this revolutionary technology has proven to do it better than anything else. The result is more clubhead and ball speed at impact.
True Temper has mastered the design in this shaft which delivers consistent flight from any lie. Variable Wall Technology at either end of the shaft is solid and firm. This allows the shaft’s midsection to be lighter and more flexible. It’s in this middle part of the shaft where the greatest amount of energy is stored and unloaded on the downswing.
Both these technologies combine to deliver golfers of all abilities fast ball speeds and the stability they need at impact to hit consistent shots.

Our Experience
I’ve long been a fan of Project X Shafts. I’ve had them in my irons for as long as I can remember. I recently put the LZ Shafts in my irons and the difference was noticeable.
Not only does the ball seem to come off hotter with these shafts, they feel exceptionally stable through impact too.
When I went through a fitting, I was surprised to find that the 6.5 flex shafts were best for my game. While I hit the 6.0s a little farther, my ball flight with the 6.5s was more consistent.
Again, I can’t emphasize enough how important it is to get fitted before putting these shafts in your irons.
