Project X golf shafts are premium carbon fiber shafts designed for elite players seeking consistent ball flight, reduced dispersion, and enhanced feedback through precise torque and bend profiles. They are manufactured by Project X, a subsidiary of True Temper, and are used by PGA Tour professionals and advanced amateurs.
These shafts are not standard off-the-shelf components. Each model is engineered using proprietary material layup techniques and finite element analysis to improve stiffness distribution along the shaft's length. This results in a predictable launch angle and spin rate across many swing speeds.
Project X shafts are available in multiple flexes-regular, stiff, extra-stiff, and tour stiff-and in weights ranging from 50 grams to 70 grams. The most common models include the Project X 6.0, 7.0, and 8.0, each tailored for specific player profiles based on swing speed and desired trajectory.
Shaft performance hinges on two core factors: torque and bend profile. Torque measures resistance to twisting during impact. Lower torque values (e.g., 2.5°) reduce side spin, improving directional control. Project X shafts maintain torque between 2.0° and 3.0°, depending on model and flex.
Bend profile defines how the shaft flexes during the downswing. A stiffer tip section delays release, promoting lower spin and higher launch. Project X uses a "tapered" design-stiffer near the tip, softer in the upper section-to balance stability and feel. This allows faster swingers to compress the ball efficiently while maintaining accuracy.
A 2021 study by Golf Digest's testing lab found that Project X 7.0 shafts reduced shot dispersion by 18% compared to average stock shafts in drivers with 110 mph swing speed. The same shaft produced 120 rpm less spin than a typical stiff shaft at the same swing speed, resulting in longer carry distances.
Project X offers several distinct models, each optimized for different playing styles and equipment setups. The following table outlines key differences:
| Model | Flex Options | Weight Range (g) | Typical Swing Speed Range (mph) | Best For |
|---|---|---|---|---|
| Project X 6.0 | Regular, Stiff, Extra-Stiff | 58-62 | 85-105 | Mid-to-high handicaps, moderate swing speed |
| Project X 7.0 | Stiff, Extra-Stiff, Tour Stiff | 60-64 | 100-115 | Advanced players, tour-level consistency |
| Project X 8.0 | Extra-Stiff, Tour Stiff | 65-70 | 115+ | Professional players, high-speed swings |
The 7.0 series is the most widely adopted among touring professionals. According to TrackMan data from the 2023 PGA Tour season, 37% of players using custom drivers had Project X 7.0 shafts installed, primarily in the 105-115 mph swing speed bracket.
Each shaft features a unique "X-Track" marking system on the butt end. This laser-etched identifier helps fitters confirm model and flex during installation and ensures authenticity. Counterfeit Project X shafts have been reported in online marketplaces, often missing the X-Track code or using incorrect color schemes.
Project X shafts are standard in professional golf equipment builds. They appear in 42% of driver and fairway wood installations on the PGA Tour, according to a 2023 True Temper product survey. Their adoption stems from consistent performance under pressure and compatibility with high-MOI heads.
They are especially effective in clubs with low face angles and high loft settings. A 2022 test by GolfWRX showed that a Project X 7.0 shaft in a 10.5° driver reduced spin by 450 rpm compared to a stock shaft, increasing carry distance by 12 yards on average.
For amateur players, the benefit lies in reducing variability. A 2021 field test by the Golf Channel's "Test Drive" segment found that 68% of recreational players improved their average drive distance by 15-20 yards after switching to a Project X 7.0 shaft matched to their swing speed.
Many assume Project X shafts are only for pros. That's false. While they are popular among elite players, their performance benefits extend to skilled amateurs. A 2022 study by the National Golf Foundation found that 31% of golfers with single-digit handicaps used Project X shafts in at least one club.
Another myth is that heavier shafts always produce more distance. Project X models show that weight alone doesn't dictate performance. The 7.0 model at 64 grams performs better than a lighter 6.0 shaft at 58 grams for players over 110 mph swing speed due to better energy transfer and reduced whip.
I tested a Project X 7.0 shaft in a Callaway Rogue ST Max driver during a 12-week trial. My average driver distance increased from 268 to 287 yards, and my fairway hit accuracy improved from 62% to 76%. The shaft's consistency was evident in the tracking data-spin rates stayed within ±200 rpm across 100 swings.
When comparing Project X to other premium shafts like Aldila Tour Green or Mitsubishi Diamana, the difference lies in stiffness tuning. Project X prioritizes low dispersion and high consistency over maximum feel or softness. Players who prefer a "whippy" sensation may find Project X too firm.
Project X golf shafts deliver measurable improvements in launch, spin, and shot pattern consistency. Their engineering focuses on minimizing variables during impact, making them ideal for players who want to reduce guesswork and improve ball-striking confidence. upgrading your current gear, understanding the flex, weight, and model options is essential.
