Project X Driver Shaft Review

True Temper Project X & Project X PXv Driver Shafts

The Project X brand name came from Royal Precision. Royal Precision, an iron shaft only company, was acquired by True Temper in 2006. The Project X brand name was part of that purchase. Project X branded driver shafts appeared soon after that purchase.  They use the same stiffness designation as the Project X irons shafts, numbers, rather than letters.  The 5.0, 5.5, 6.0, 6.5 & 7.0 numbers designate stiffness.  The original numbering scheme was formula based and came from frequency and length.  The numbering system on the Project X driver shafts, like all other driver shaft stiffness designations I have seen are based on both weight and stiffness.  A heavier 6.0 shaft will also be a stiffer 6,0 shaft.

TTPX Composite Ei.fwI looked at four versions of the Project X driver shaft, the original Blue, the lighter weight Black, the newer, PXV Tour52 and the PXV. The profiles are compared in this chart. With the exception of the PXV Tour52, the bend profiles are quite similar. The nearest match my software located was the Graphite Design TourAD BB. The Project X has about .6 degrees more torque than the Graphite Design TourAD BB. You can expect a lower than average launch from the Project X driver shafts.

This shaft has been with us for a few years.  In the 6.5 model, stiffness is added to the tip. The slight bump seen in the average chart is an indication of that stiffness showing up in the averages. Radial quality is excellent, meaning alignment if the Project X family of driver shafts will not matter. TTPX EIGjTt Blue.fw

The original Project X blue was lightened ever so slightly in the Project X Black version.  And, as you can see, the tip was softened to create a higher flight. Quality is excellent, All weights and flexes follow the same bend profile design.TTPX EIGjTt Black.fw

Project X PXv Tour 52

The PXv Tour52 is a different shaft. In a light weight shafts, this profile is a low launch design. The traditional concept of the Project X was low launch and looking at this profile, I can see a design that honors that tradition. In this weight range, the torque numbers are quite low.  Typically as weight goes down, torque goes up, not so with the Project X PXv Tour 52.

The Project X PXv is very similar to the original Project X Blue. The tip is a little tighter and stiffer. It makes sense to not make big changes to something that works. As with many revisions, the graphics get updated, and small changes, typically the result of upgrades in carbon fiber material, address tour feedback. Once again, in the stiffer versions, there is a low mid stiffness bump to give the stronger player tip stability.

    I have a project x blue 5.0 driver shaft. Is this shaft the right flex for my golf driver
    swing from 85-90 mph?

    • DevotedGolfer

      That cannot be answered by swing speed alone. Everyone loads differently and your relationship with any particular shaft is best explored with a qualified club fitter. Qualified meaning someone that truly understands swing mechanics and shaft profiles.

    I am looking for a lightweight shaft to play full 46″ for a 188 gram driver head (R7 Quad with lighter weights) to keep swingweight around D3. My average swing speed with normal weight driver and 45″ shaft is 117 mph with peak of 122 mph. Which of all the lightweight shafts you’ve reviewed would hold up to my swing speed and give me mid launch and mid-low spin? Thanks

    • DevotedGolfer

      Tom,
      I don’t pull out the lightweight stuff when I fit your swing speed range. With that kind of speed you have nothing to gain from a light weigh shaft other than dispersion and massive snap hooks when you go after it.

    looking to replace the stock r flex shaft in my r9 my miss is high left hook. i was thing about a S flex project x PVx 63 or 78g. what do you think?
