Here's the decision. You're looking at a current, stepless steel iron shaft with a firm, stable profile. True Temper classifies it for low trajectory, low spin, and fast tempo, but those aren't guaranteed launch-monitor results. Independent comparisons show that Project X, Dynamic Gold, and KBS can finish within a couple hundred rpm or a yard or two for a well-matched player. Test it if you like a firm feel and want controlled flight. Don't buy it from a swing-speed chart or because somebody promised extra yards.
Quick Overview
The original Project X is a stepless steel iron shaft, not a blanket name for every Project X wood, iron, and wedge product.
True Temper lists .355 taper flexes from 5.0 to 7.0 at 110 to 130 grams, plus .370 parallel options in 5.5, 6.0, and 6.5.
The current price is $48.99 per raw shaft at True Temper, GolfWorks, and Fairway Golf USA.
Independent testing supports a firm, controlled profile for matched players but not fixed spin, dispersion, or distance gains.
Buy it after a fitting, not from a swing-speed chart. Compare Dynamic Gold, KBS Tour, Project X LZ, and Project X Red.
Project X Shaft

What the Stepless Design Actually Means
The original Project X uses a smooth exterior taper instead of the visible steps you'll see on standard Dynamic Gold. That's a real design difference. It doesn't prove that visible steps interrupt energy transfer, and it won't guarantee more distance.
The full stiffness and mass profile matters more than the exterior shape. Independent EI analysis found Project X slightly softer in the butt and stiffer through the midsection than Dynamic Gold X100 in the samples measured. That's why you might call it stable while somebody else calls it harsh.
You may see the expected penetrating, lower-spin flight. You can also get the opposite: higher flight, lost distance, or less awareness of the clubhead. Honestly, that kind of variation is why you should compare shafts in the same head instead of treating “low spin” as a promise.
Flex, Weight, and Who It Fits
Current .355-inch taper options run from 5.0 to 7.0. Nominal weights rise from 110 grams at 5.0 to 130 grams at 7.0. The .370-inch parallel version is currently listed in 5.5, 6.0, and 6.5 at 115, 120, and 125 grams.
You're reading Project X's own flex scale. Club brands sometimes place familiar R, S, or X labels beside those numbers, but that shorthand doesn't make flex universal. True Temper doesn't publish a guaranteed swing-speed range for each number.
Choose flex with a fitter who can evaluate your transition, release, strike, launch, spin, peak height, and landing angle. A hard-stepped or soft-stepped build also changes the finished club. If a 6.0 feels dead or you can't find the center, a faster swing doesn't make it right.
Do Not Confuse It With Project X Graphite Wood Shafts
The older Project X Black driver shaft is a separate graphite wood-shaft product. You can't carry its TeXtreme material claims or driver test numbers into a review of the original steel iron shaft.
Project X separates its steel products from HZRDUS, Denali, and TITAN graphite wood shafts. You're dealing with different materials, weights, tip diameters, and profiles. A good fit in the steel iron model doesn't predict your driver shaft.
The same rule applies to manufacturing. True Temper says its steel shafts are made in Amory, Mississippi. Its Project X brand page separately describes San Diego production for HandCrafted graphite. You won't get an accurate origin without naming the exact model.
Project X Wedge Is a Separate Product
Project X Wedge is a separate current shaft. It isn't proof that you'll get one continuous profile from driver through wedge. It has its own product page, specifications, and fitting purpose.
You can use the original taper shaft in the wedge length offered by True Temper, or a fitter can recommend the dedicated Project X Wedge model. Neither choice guarantees tighter dispersion or more spin. Your head design, loft, strike, build, and delivery all contribute.
If your scoring clubs need more launch, feel, or partial-shot control than your irons, test them separately. You don't need the same name on every shaft. You need the flight and distance control that works.
Original vs Red vs LZ
You've got three clear starting points. Original Project X is the firm, stable option. Project X LZ uses a softer midsection so you'll feel more load. Project X Red is positioned for higher launch and spin.
A 2026 fitter comparison of original 6.0 and Red 6.0 found less than one mph of club-speed difference and no ball-speed difference. Red launched about 1.5 degrees higher, peaked about eight feet higher, and landed about 2.2 degrees steeper in that comparison. It was roughly 1.5 yards shorter. You may react differently.
LZ costs $53.99 per raw shaft, while original and Red are $48.99. ExactGolf found no meaningful launch or spin difference between original 6.0 and LZ 5.5 for its player. Use the family labels to decide what you'll test, not to predict your final numbers.

Is the Project X Shaft Worth It?
Yes, for the right fit. At $48.99 per raw shaft, Project X costs more than standard Dynamic Gold at $32.99 and KBS Tour at $34.95. An eight-shaft Project X set is about $391.92 before grips, labor, or fitting.
Pros:
Firm, stable profile for players who fit it.
Five taper-tip flex and weight options from 110 to 130 grams.
Current .355 taper and .370 parallel availability.
Long-running model with current named tour use.
Cons:
Can feel harsh or hard to load for some golfers.
Costs more per shaft than Dynamic Gold or KBS Tour.
Low-flight fit can reduce stopping power.
The numerical flex scale encourages bad one-number recommendations.
Frequently Asked Questions
Where Are Project X Shafts Manufactured?
True Temper says its steel shafts are made in Amory, Mississippi. That supports the original steel Project X covered here. Project X also sells separate graphite families, and its brand page identifies San Diego production for HandCrafted graphite, so origin must be tied to the exact model.
What Is the Warranty Period for Project X Shafts?
True Temper provides a one-year limited warranty to the original purchaser for shafts bought directly from TrueTemper.com with proof of purchase. If you buy through a dealer or club manufacturer, start the claim with that seller because its terms apply. Improper installation, alteration, reinstallation, abuse, impact, and normal wear are excluded.
Can Project X Shafts Be Reshafted Into Existing Clubs?
Yes, if the shaft and build match the clubhead. The original is available in .355-inch taper and .370-inch parallel tips. Verify the hosel, trim instructions, finished length, head weight, and swing weight before installation. A qualified builder is the safest option.
How Much Do Project X Shafts Typically Cost?
The original Project X steel iron shaft was $48.99 per raw shaft at True Temper, GolfWorks, and Fairway Golf USA when checked on August 20, 2026. Grips, trimming, fitting, and installation cost extra. Other Project X families have separate prices.
Are Project X Shafts Available for Left-Handed Golfers?
Raw Project X iron shafts are not inherently right- or left-handed. A retailer's right- or left-hand PUREing option describes how an optional alignment service is installed in the finished club. It is not a different shaft model.
Final Thoughts
The original Project X remains a credible steel iron shaft, but the old article asked it to prove too much. Stepless construction doesn't guarantee extra yards. A 6.0 label doesn't select itself from swing speed. Driver-shaft results don't transfer to an iron shaft.
Test Project X if you want a firm, stable profile and controlled flight. Compare Dynamic Gold if value matters, KBS Tour if you want a smoother mid-trajectory option, Project X LZ if you want more load sensation, and Project X Red if you need more height. The best result is the one that improves your strike and dispersion without costing the peak height and landing angle you need.
