Features &
Benefits

47” Length Shaft

  • A longer 47” shaft helps the player generate more club head speed. Longer length shafts can be used in all Callaway Driver Heads. Custom builds are available from 46”-48”.

Strong OptiFit Hosel

  • A strong cog allows player to chooses from -2°, -1°, STD, +1° loft settings.

Lighter Interchangeable Head Weights

  • Lighter interchangeable head weights are stock to help dial in the proper swing weight.

Fitting Guidelines

Most players opt to play one loft degree stronger vs. their current driver.

  • Longer shafts typically increase launch angle
  • Strong cog will allow the player to reduce loft by up to 2°

Many players choose a shaft that’s about ~10 grams lighter than their standard-length driver.

Most players choose the same shaft flex as their standard-length driver.

Longer shaft configuration will result in heavier stock swingweights.

  • Lighter interchangeable weights help, and you should expect the swing weights to be heavier than in a standard-length driver

"The longer driver shaft is all about speed. The longer the shaft, the more time you have to maximize speed at impact. I go to the limit of what I can handle, and from there, try to hit it as hard as I can."
