Project X Shafts Reviewed – Are They Any Good?

As a brand of True Temper – the makers of arguably the most popular iron shaft in the world – Project X shafts get a good deal of attention.

And for good reason. Project X shafts have been called some of the most stable and smooth shafts on the market.

There’s no question about the quality of Project X shafts. The only issue comes in the form of variety. There are a lot of different Project X shafts to choose from which can make it difficult to select the one that is perfect for your game. But in the following list, we will break down some of the most popular Project X shafts and tell you what kind of player they suit.

Project X LZ Shaft Review

Selling Points:

  • Variable wall technology
  • Active midsection
  • Firm but and tip section

The Project X LZ shaft comes in 110g, 115g, 120g and 125g versions. With the LZ, it seems that Project X was trying to appeal to as many players as possible. That’s because it isn’t as stout as other Project X shafts; but it still offers a high degree of stability. It has a very smooth transition that invites you to swing outside of yourself and in the heavier weights, can keep up with aggressive transitions. Dispersion is tight and the flight can be worked from mid to high.

Who is it for?

The Project X LZ is a great fit for mid handicappers who are trying to avoid the overt stiffness of steel iron shafts. It can still keep up with fast swing speed players though – just make sure you get the heavier versions.

Project X LZ Options

  • Regular flex
  • Regular+ flex
  • Stiff flex
  • Extra stiff flex

Pros & Cons

Pros:

  • Very smooth transition
  • Stepless design
  • Controlled spin

Cons:

  • The midsection can feel a bit noodly

Overall Score: 98/100

Project X IO Shaft Review

Selling Points:

  • Progressive weighting
  • Mid/low launch
  • Brushed steel finish

The best thing about the IO shafts is the progressive weighting. This makes the long irons more manageable and adds stability to the short irons. Performance is dynamic: you get the speed you need from the long irons and acute launch/distance control in the short irons. The IO shafts don’t have a very stout feel. Instead, you can feel the shaft load and release clearly in the midsection.

Who is it for?

The Project X IO shaft is a great fit for players who found the original Project X shafts a bit too stiff.

Project X IO Options

  • Regular+ flex
  • Stiff flex
  • Extra stiff flex
  • 105g, 110g, 115g weight

Pros & Cons

Pros:

  • Easy to activate
  • Good distance
  • Good control

Cons:

  • Not great for 95+ MPH swing speeds

Overall Score: 96/100

Project X Riptide Shaft Review

Selling Points:

  • Torsional stability optimization
  • Mid spin
  • Mid launch

When I first tested the Project X Riptide, the first thing I noticed was the weight. This is a very light driver shaft with a very active feel. Club head speed was 100+ MPH on almost all my swings and carry distance was consistently in the 250-yard range. My only gripe was that the flight was a bit erratic.

Who is it for?

The Project X Riptide shaft is a great option for slow swing speed players who want to improve their smash factor and distance.

Project X Riptide Options

  • Regular+, stiff and extra stiff flex
  • Counterbalanced version available
  • 88g

Pros & Cons

Pros:

  • Lightweight
  • Good carry distance
  • Good stopping power

Cons:

  • Unpredictable flight

Overall Score: 95/100

Project X Evenflow Shaft Review

Selling Points:

  • Even bend profile
  • Smooth transition
  • Efficient swing energy transfer

The Project X Evenflow feels active through the whole shaft. Of all the Project X shafts, I felt like this one was transferring my swing energy the most efficiently. You can feel the whole shaft bend and convey your swing power to the ball. The active feel remains controlled; but still may not be favored by heavy hitters.

Who is it for?

The Project X Evenflow is a good choice for players with deliberate tempos and swing speeds within 75 and 90 MPH.

Project X Evenflow Options

  • Black and Blue versions
  • 65g weight class
  • 75g weight class

Pros & Cons

Pros:

  • Low spin version available
  • Effortless club head speed
  • Good for deliberate tempos

Cons:

  • Not great for aggressive tempos

Overall Score: 97/100

Project X LS Shaft Review

Selling Points:

  • Low spin design
  • Matte gray finish
  • Stiff profile

The Project X LS is not for the faint of heart. This is a steel iron shaft on the heavy and stout side. There is only a feeble kick so even when you swing out of your shoes, you can keep track of the club head every step of the way. The spin stays low as advertised so you have to be a bit careful about rollout. In general though, this is a very accurate and durable shaft. Very tight dispersion and low flight.

Who is it for?

The Project X LS is definitely for 95+ MPH swing speed players who need a shaft that can keep dispersion tight even with a very aggressive tempo.

Project X LS Options

  • Stiff, extra stiff, tour extra stiff flex
  • 120g, 125g, 130g weights
  • .355” tip

Pros & Cons

Pros:

  • Very stable
  • Great for fast swingers
  • Very workable

Cons:

  • Harsh feel on mis-hits

Overall Score: 96/100

Project X Cypher Shaft Review

Selling Points:

  • Low resin design
  • Lightweight
  • Iron or wood versions

With my driver, the Project X Cypher produced high launch and surprisingly low spin for a shaft of this weight. It feels fast on the downswing and you can feel the bend point just below the grip section. The low spin kept dispersion tight and produced long rollouts. And for my swing, the low spin/high launch combo produced carry distances that were consistently in 260 yard range.

Who is it for?

The Project X Cypher is a good driver shaft for players who are seeking more distance and who want to find the heart of the fairway consistently.

Project X Cypher Options

  • Senior, regular+, regular and stiff flex
  • 47g, 48g, 49g weight
  • Wood or iron shafts

Pros & Cons

Pros:

  • Lightweight
  • Good smash factor
  • Accurate

Cons:

  • A bit whippy

Overall Score: 97/100

The “Smoke” line of shafts come in red, green and black versions. The HZRDUS Green is the stoutest, lowest-spinning version. The HZRDUS Smoke Red is the highest-launching version and the HZRDUS Smoke Black is the middle launch/spin version.
