The XCG-4 features a tungsten sole and a slightly larger maraging steel cup face and crown than the previous XCG-3. Maraging steel is used over stainless steel because it possesses superior strength and toughness without losing malleability. The end result is better rebound and feel than stainless steel.

The lightweight ultra-thin maraging steel cup face and crown launch the ball with less spin and faster speed.

The majority of the club’s weight is in the rear heel and toe of the sole. This set up is achieved by the heavy tungsten sole plate.

Two internal weight pads improve sound, feel, and the center of gravity location for a more pure energy transfer at impact.

Tungsten is twice as heavy as steel allowing even more weight to be placed below the ball for improved performance. The resulting center of gravity angle is extremely deep, helping the club face square at impact with more force for a quick launch and longer, more accurate shots.
