Project X’s tour-caliber 39-gram driver shaft

Certain numbers in sports have an almost mystical value to them, like running a mile in less than four minutes. Recently, True Temper broke one of those key figures — a driver shaft that weighs less than 40 grams.

According to True Temper, its Project X PXV 39 is the first PGA Tour-caliber shaft that weighs less than 40 grams at a length of 46 inches.

“This is for the guy who’s looking for the ultimate in club head speed,” said Don Brown, product developer for True Temper.

Because of the way the weight is distributed in the shaft, the PXV 39 will allow golfers to build a club with the lightweight shaft at either 46, 46.5 or 47 inches and still have a swing weight at D5 or less.

Brown said the mid-launch, mid-spin shaft has been in the works from True Temper for nearly 10 years. Originally, it was going to be used just for recreational players, but it has been tested and put in play by professionals in Europe and the U.S.

“We wanted to do our testing with Tour players because of the ball speeds they bring,” Brown said. “As it turns out, this shaft fits a lot of Tour players very well.”

Check out the video interview about the PXV 39 with GolfWRX’s Zak Kozuchowski and Brown to learn more about the shaft.

I just recently purchased a taylor made SLDR driver with a pxv39 shaft. I twas the best driver head shaft combo i have ever hit. the problem was after 5 1/2 rounds the shaft snapped in half just below the midpoint, for a brand new shaft to do this it either had a defective shaft or it cannot with stand very many strikes at the ball. I am looking for some feedback on this as I have ordered another one and don’t want the same thing happening with a $350.00 shaft. please reply with any info you can, thank you

I can’t see a quick, aggressive swinger like Ricky Fowler, Rod Pampling, or a young Nick Price having a whole lot of success with this light of total weight. And 47″, that’s 2.5″ longer then the average length on the PGA Tour. Time will tell though.

I’d bet that shaft feels ‘whippy’….a lot of movement in the tip. Maybe I’m wrong…but Id bet it does.

  Surprisingly solid feel. I thought it would feel whippy too. After 3 hits I was really striping it. Ordered a couple days ago. Can’t wait to start blasting it. Now the question is what to throw in the 3 & 5 woods.

Game improvement iron as a driving iron? – GolfWRXers discuss

Published

In our forums, one user is sharing details of a recent round in which his playing partner was gaming an…unconventional driving iron.

@AbSWFPGA explained:

“Played with a kid the other day who was a good player and he used a TaylorMade qi max hl 4 iron as a driving iron. He hit it off a lot of tees and it was pretty money. I looked up the 4 iron in that set and it’s 18.5 degrees so that would make for a good driving iron in terms of loft. Has anyone done this and could share some feedback? Thanks”

Our members have been sharing their own perspectives and experiences with unique driving irons in the forum.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

Dave33: “I just got a new set of irons, Ping I540’s, and the 4 iron is 19 degrees. That’s basically as strong as the 2 iron in my 30 yr old custom set its replacing and I used to hit that 2 iron off the tee all the time. The I540 4 iron off the tee is an awesome club. ”
Santiago Golf: “I have tried this a few times and they always went too high … Never really the stinger height I was looking for. I got a IDEA Pro style hybrid and it was the perfect mid launching club I was looking for.”
DircaDelta: “I basically do this with a JPX 925 Hot Metal Pro 4iron (19 degrees). I tried a few driving irons but honestly this probably fits me best due to the shorter length, but it’s still hot and still has a wide sole which is nice. Great off the tee, turf, and punchy shots to lay-up on par 5s or get out of trouble. It has the same shaft as my irons (Modus 120X) so I could probably get more out of it from a different shaft, but it fits what I need in terms of gapping from my 5 iron (JPX Forged) and gapping and launch from my short 5 wood. I think it’s a good (and often cheaper) route so long as you can find one that suits your eye and gapping needs. I don’t like offset so the HMP’s help in the optics department over a “more typical” game improvement iron.”
