Project X LZ is a current .355 taper-tip steel iron shaft with a firm butt and tip around a softer loading zone, but its $53.99 price and fit-sensitive response make blind reshafting a bad bet.
Start with your current iron build before you price a full reshaft. You need your existing shaft model, flex, playing lengths, swing weights, and normal miss. Then you can test LZ in a comparable head and watch your strike, start direction, peak height, and dispersion. You should not assume the softer middle will automatically give you more speed or launch. Your transition and release determine whether you feel the loading zone as helpful or unstable. If you like the response, have your shop document the exact raw shafts, tip format, trimming, and finished specs. That record protects your result when you replace or rebuild one club later.
Before you commit, ask whether you can test your flex in your head, whether your shop can match your swing weights, and whether you can keep your final build sheet. You need your result to be repeatable across your set. Can you center the strike? Can you control the face? Can you repeat the window? Your transition, your strike, and your dispersion should support your choice.

Is the Project X LZ steel shaft worth buying?
Yes, when a fitting shows that its 110-to-125-gram weight and pronounced midsection load improve strike and face delivery. It is not a guaranteed distance, launch, or dispersion upgrade. Eight chrome shafts cost $431.92 before grips and labor, so test LZ against original Project X, Dynamic Gold, KBS Tour, and other golf shaft options in the same head.
Use this review to narrow your fitting, not choose your flex from a screen. You need the same head, ball, loft, lie, length, and swing-weight target when you compare shafts. You should track your strike, start line, peak height, spin, carry, and late-session fatigue. If you like the load but your miss widens, test another flex. If your height falls, test less weight. If your timing improves, repeat the session before you order a set. Honestly, you should know what your completed club is solving. The printed number is kind of useless when your build and your delivery do not match the person who wrote the flex chart. The old review blended current steel LZ with legacy graphite wood and iron products, used unsupported FlexLok and three-wall language, and attached exact TrackMan gains without retained data. This article covers only the current Project X LZ steel iron and wedge shaft.

Project X LZ Shaft
Project X LZ Shaft delivers explosive distance and buttery-smooth feel for elite-level ball control.
The Loading Zone Is Real, but FlexLok and Graphite Claims Were Wrong
The current LZ steel design uses a softer midsection between stronger butt and tip sections. GolfWorks describes variable-wall construction and rapid tapered steps through the loading area. The intended result is more perceptible load and release than original Project X without giving up tip support through impact.
That identity matters because Project X has used LZ on different products. A legacy handcrafted graphite wood shaft used FlexLok terminology, and an older LZ Tour graphite iron shaft was a separate model. Neither is a material option for today's steel LZ. The live page's FlexLok, three-wall, LZ-55 wood, and LZ Tour 90 graphite language mixed those families together and has been removed.
The current steel shaft is visibly stepped and sold in discrete .355 taper lengths. True Temper's direct page begins with a 39.5-inch 4-iron shaft and ends with a 36.5-inch wedge shaft; GolfWorks also lists a 40-inch 3-iron option. A builder selects the shaft intended for the club number, then completes the build to the planned playing length and swing weight.
Project X also repeats a 7 percent greater energy-transfer claim. No public methodology, player count, baseline, or measurement protocol was found for that figure. It should remain a manufacturer claim, not a promise of more smash factor or distance. Energy transfer is not one isolated shaft outcome because you can change speed, strike, delivered loft, and face position in response to feel.
The useful takeaway is simple. LZ has a distinct load pattern that many golfers can feel. Whether that sensation improves the completed club is a fitting question, not a technology-word contest.
The Flex Number Is Not a Universal Stiffness Scale
Current LZ options are 5.0 at 110 grams, 5.5 at 115, 6.0 at 120, and 6.5 at 125. Retailers often translate those labels to regular, regular-plus, stiff, and extra stiff. Those are shopping shortcuts. They do not prove that LZ 6.0 measures or feels like every other stiff shaft.
Independent comparisons make that warning concrete. Published hands-on testing's published account normally used a different Project X flex but preferred 6.0 in LZ. ExactGolf compared original Project X 6.0 with LZ 5.5 because those samples measured close in overall stiffness. Selecting the same printed number across both models would not have created the intended comparison.
Weight matters just as much. You who fits a 110-gram 5.0 is not buying the same total-mass experience as a 125-gram 6.5. Heavy steel can reduce speed, peak height, or late-round consistency for some players. Dropping to a softer printed flex does not automatically solve a weight problem because the product still begins at 110 grams.
Raw shafts are not left- or right-handed. A retailer's paid orientation service may use a handedness label, but it is an installation process, not a separate raw shaft. Likewise, current LZ is not a universal hybrid shaft. The .355 taper tip must match the head and the correct discrete shaft must be selected.
Do not buy by seven-iron speed alone. Transition, release, strike pattern, desired height, spin, fatigue, and feel belong in the decision. Compare the same head and ball, then use the flex and weight that produces the most repeatable delivery rather than the label that flatters your ego.
If you're between choices, build one test iron at your normal length and target swing weight. Hit it late in the session, not only while fresh. Your start line, contact, peak height, and fatigue will tell you more than a retailer's regular-or-stiff translation.
Independent Testing Supports the Feel, Not Universal Performance Gains
Multiple published accounts describe the same broad sensation: a stable butt and tip with a clearer midshaft load than original Project X. Published hands-on testing found more kick, a mid-launch window, and useful trajectory control. Published launch-monitor testing described a crisp, active response and controlled release. Those accounts support product identity, but neither published a shot-level dataset that predicts another golfer's result.
D'Lance Golf provides the best accessible multi-measured account account. It tested indoors with TrackMan and Callaway Chrome Soft balls using shafts chosen near each golfer's fitting specification. Lighter LZ examples launched in a similar neighborhood to KBS Tour R and C-Taper Lite R, while heavier versions landed among several common stiff profiles. Every measured account produced a higher smash factor with LZ than with the comparison shafts, and the author explicitly called the result inconclusive. Both halves of that finding matter.
ExactGolf found no meaningful launch or spin difference between its original Project X and LZ comparison. Its player handled original Project X better, and LZ produced more directional outliers. The report also explains that another golfer could produce the opposite result. That is the responsible shaft-review conclusion.
The old page's exact claims, 18-to-12-yard dispersion, 1.46-to-1.48 smash, two more degrees of launch, 2-to-3 mph ball speed, and 5-to-7 yards of carry, had no retained test record. They are gone. LZ can help when its weight and loading pattern improve timing. It can also add unwanted spin, feel unstable, or widen the miss when the match is wrong.
Honestly, a shaft does not know what launch window the product page promised. It responds to you and the completed club.
Eight Shafts Cost $431.92 Before Installation
Chrome LZ costs $53.99 per raw shaft from both True Temper and GolfWorks. Eight shafts total $431.92 before grips, ferrules, fitting, pulling old shafts, installation, loft-and-lie checks, and swing-weight work. The $64.99 Blackout version costs more than chrome across a full set.
The comparison math is useful. Standard Dynamic Gold at $32.99 costs $263.92 for eight, saving $168. KBS Tour at $39.95 costs $319.60, saving $112.32. Original Project X at $48.99 is only $40 less across eight. Those products do not feel identical, but they show how much of the purchase is a profile decision rather than a general quality upgrade.
LZ remains current nearly a decade after its May 2016 launch, and current tour use confirms that it can work at the highest level. Tour use does not tell a recreational golfer which flex to buy. A $432 experiment is still expensive when the head, grip, and build are not controlled.
The sensible process is to fit one or two clubs first. Keep the head, loft, lie, ball, and finished length consistent. Compare strike, start direction, height, spin, carry, and the size of the miss. Then hit enough shots to see fatigue and timing changes rather than judging one perfect swing.
If LZ produces the best repeatable pattern and the load feel helps you sequence the club, the premium is defensible. If Dynamic Gold, KBS Tour, original Project X, or a lighter option matches the numbers, spend the difference elsewhere.
You also need to price the exit. If the completed set does not fit, pulled shafts lose value and the direct warranty excludes reinstalled components. A one-club test is kind of boring compared with opening eight boxes, but it is a much cheaper way to learn.
Installation and Warranty Rules Rule Out Casual Shaft Swaps
Current LZ is sold as discrete .355 taper-tip iron and wedge shafts. Select the raw shaft for the correct club number, verify the hosel, and use the manufacturer's build instructions. Do not apply generic parallel-tip trimming advice, do not assume every hybrid accepts it, and do not transfer one installed shaft between heads as though the warranty and build remain unchanged.
True Temper's public warranty is one year for original purchasers who buy directly from TrueTemper.com. Retailer and OEM purchases must be handled through the seller. Proof of purchase is required, and the direct policy excludes shafts that have been pulled and reinstalled. Cosmetic wear on Blackout is also excluded.
That does not mean every legitimate dealer build lacks protection. It means the claim route depends on the channel. Ask the fitter or retailer who handles a defect before installation and keep the receipt, shaft labels, and build sheet.
Finished swing weight is another reason to involve a builder. Shaft weight, balance, raw length, head weight, ferrule, grip, and final length interact. A correctly installed shaft can still create a poor club if the total build misses you's target.
LZ is best for someone already comfortable with 110-to-125-gram steel who wants more midsection load than original Project X. It is a poor blind buy for you chasing distance, struggling with heavy-shaft fatigue, or planning a casual garage transfer without confirming the exact components.
When you collect the finished clubs, verify playing length, swing weight, loft, lie, and grip orientation before leaving the shop. Those checks create a baseline if one club later feels different and prevent a build error from being mistaken for a shaft-performance problem.

Frequently Asked Questions
What does LZ mean in Project X LZ?
LZ means Loading Zone. The current steel shaft uses a softer midsection between firmer butt and tip sections, with visible rapid steps through the loading area. FlexLok belongs to a separate legacy graphite product and should not be used to describe the current steel iron shaft. If you are comparing it with standard Project X, focus on how the middle loads and whether that changes your strike and face delivery. The loading sensation is the product's real distinction. It is not a certified percentage gain in speed or distance.
Is Project X LZ 6.0 a stiff shaft?
Retailers commonly label 6.0 as stiff, but Project X numbers are not universal stiffness units. LZ 6.0 weighs 120 grams, and an independent comparison matched original Project X 6.0 with LZ 5.5 because those samples measured closer. Test the exact model instead of transferring the printed number. You should compare measured stiffness, weight, and completed-club performance rather than buying the label you used before. The correct choice can move up or down a printed flex depending on the head, finished length, swing weight, transition, and the feel you respond to.
Does Project X LZ launch higher than standard Project X?
It can for some golfers, but not universally. Several published accounts saw mid flight or more kick, while ExactGolf found no meaningful launch difference in its comparison. Weight, flex, head, strike, and delivery decide the actual window. For your fitting, use the same head, loft, lie, ball, and finished length and compare average peak height, spin, strike, and start direction. A design category such as mid launch describes the product family; it cannot predict your delivered loft or impact pattern.
Can Project X LZ go in a hybrid?
The current product reviewed here is a discrete .355 taper-tip steel iron and wedge shaft. Hybrid compatibility is head-specific, and most hybrid claims on the old page were unsupported. Confirm the hosel and build instructions rather than assuming the shaft fits. If you are building a utility iron or unusual head, ask the manufacturer or a qualified builder for the exact tip and shaft-number requirement. A forced fit or casual tip alteration can damage the component and produce a club that misses the intended swing weight.
What warranty applies to Project X LZ?
True Temper states one year for qualifying original direct purchasers. Dealer and OEM claims go through the seller, proof is required, and pulled-and-reinstalled shafts are excluded from the direct warranty. Confirm the claim route before installation. Keep the invoice and build record, and ask the seller who handles a defect before installation. Your dealer may provide a valid claim route, but it is not the same as the direct-purchase policy. Cosmetic wear and installation damage are separate from manufacturing defects.
Final Thoughts on Project X LZ
Project X LZ has lasted because it gives golfers a recognizable load sensation without abandoning tip support. That is a legitimate fitting option, not proof of more distance. The data shows different players can launch, spin, and disperse the same shaft differently.
Test the correct weight and flex in the intended head, calculate the full build cost, and let repeatable impact decide. If the LZ profile wins, pay for it. If it does not, the $432 shaft label will not rescue the set.
