Rifle Project X Individual Iron Shaft

The complex Rifle Project X Iron Shaft was in development for more than two years, and represents the most advanced steel shaft technology available today.

Each shaft in a set has a different, dedicated constant taper per inch, transferring more energy to the clubhead. The result is a stepless shaft and a ball that rises faster and then flattens out for a more penetrating trajectory.

Bend Points: Mid/High. Step Pattern:Stepless

Flex Equals:

  • 4.5 = Regular
  • 5.0 = Regular +
  • 5.5 = Stiff
  • 6.0 = Stiff +
  • 6.5 = Extra Stiff
  • 7.0 = Extra Stiff +

Write a Review for the Project X .370 Steel Iron Shaft
Rated 5 out of 5 by 8 reviewers.
Rated 5 out of 5 by Best shaft Going IMOHO Have built several sets with these project x shafts and every one performs well. All have been pured and have a consistant feel to them. Havent bought any since true temper bought the company but i hope they stay the same. The stepless shaft in satin gives the clubs a "sexy" feel. With the stiffer flex (7) i get a long boring ball flight with increased accuracy. March 31, 2012
Rated 5 out of 5 by Rifle Project X Individual Iron Shaft One factor is shaft weight. With somewhat lighter shafts I could pick up some clubhead speed. February 2, 2012
Rated 5 out of 5 by Great shaft but stiffer than flighted Fitted a set of 6.5 s in my 10yr old ping i3 Blades as stock shaft was balloning at my windy but hot course in Barbados where I teach. They transformend the irons such that I still play them because of the penetrating ball flight [the ball really does rise and then flatten out] 5 iron 190yds carry 175 with old shafts much better dispersion as well , I agree they feel heavier then similar weighted shafts but i like this as it stops me being quick and i like to feel the club on back swing. Love them May 20, 2010
Rated 5 out of 5 by worth the price probably the best feel and flight of any steel shaft on the market June 12, 2009
