What Is an Asymmetrical Bowling Ball? Simply put, when bowling balls have asymmetrical cores, it means the inside of the bowling ball is heavier on one side than the other. The core weight is not even like it is in symmetrical bowling balls. The asymmetrical core type imbalance is what helps the bowling ball hook.

An asymmetrical bowling ball is a bowling ball that has an asymmetrical core inside. It is a new core technology that is an improvement from the popular symmetrical core. What defines this type of core is if you happen to cut the core in a straight line from top to bottom, the two halves fit into each other.

Asymmetric Bowling Balls: On the other hand, asymmetric cores possess a more complex mass distribution, creating an imbalance within the ball. These cores come in various shapes, such as elliptical or mushroom-like designs. The imbalance causes the ball to rev up more aggressively and respond to friction with increased hook potential.
