S300 vs. S400

Many golfers have communicated confusion around the topic of the s300 and s400 shafts. What is the difference in terms of weight, stiffness, and manufacturing accuracy? Is one better than the other, and who should use which?

Here we are going to dive a little deeper and clear up any confusion.

What Are True Temper Dynamic Gold s300 and s400

True Temper Dynamic Gold s300 is the standard stiffness and flex for golf shafts. It is not the only one, but it is the median shaft construction and is the standard by which every other shaft is compared.

The s400 golf shaft, also known as Dynamic Gold s400, is slightly heavier and stiffer than the s300, although it would take an extremely discerning golfer to pick out the difference between the two weights.

In comparison to the S300 and S400 shafts, the Dynamic Gold X100 offers an even stiffer flex and is typically chosen by highly skilled golfers with faster swing speeds.

Is s400 Stiffer Than s300

When asking ‘which Dynamic Gold shaft is stiff?’, some golfers may say that the s400 is stiffer than the s300, while others claim they exhibit the same stiffness, with the only noticeable difference being in weight.

The s400 is meant to be slightly stiffer, but the difference is tough to pick up on. A golfer may notice that the s300 has a somewhat softer feel than s400.

One crucial factor to note is that shafts are often weight sorted, but sometimes not precisely. Some s400 shafts on the market may have been s300’s that weighed in a little too high.

There is an allowance within the manufacturing process of a couple of grams in each direction. Meaning a shaft that was meant to be 130 grams weighs in at 132 grams, so it is sold as a shaft meant to be 134 grams.

📋 Keep in mind: The Dynamic Gold “Tour” issue is sorted plus or minus half a gram on each side, giving these shafts more consistency between products. This is a minimal difference, but one that could affect a professional’s game.

Key Differences Between Both Shafts

There are a few differences to note between the two shafts. The Dynamic Gold s300 weight is 130 grams, and it has more flex than the s400 (supposedly), although most golfers can’t notice the difference.


  • Weighs 130 grams
  • Higher ball flight
  • More spin


  • Weighs 134 grams
  • Lower ball flight
  • Less spin

Does Iron Shaft Flex Make A Difference

Flex comes down to the way the club is swung. However, when tested, regular shaft flexes performed as good or better than stiff shafts.

Irons naturally have stiffer shafts since they are shorter. A more rigid shaft may be a little more abrupt in the hands while having slightly more flex can aid to a softer feel.

Higher flex shafts have proven to be just as, or more, accurate than stiff shafts. The players who should use shafts with lower flex are ones with aggressive swings. In comparison, golfers with smooth and controlled swings can get away with higher flex and achieve the same results.

📋 Keep in mind: When determining the proper shaft for a player, the most important factor is the fit, which means the length and weight given the golfer’s body size.


Be sure you’re getting the right fit, and flex for you by having your clubs fitted professionally. Otherwise, leave your comments and queries in the section below.


How heavy are S400 shafts?

The True Temper S400, also known as the Dynamic Golf S400 shaft, weighs about 132 grams, has a stiff flex, and is known for its high kick point that leads to low spin and low trajectory.

What stiffness is S300?

The S300 is a stiff flex shaft. It is considered to be a normal stiff unlike other shafts that are borderline regular flex or extremely stiff and heavy.
