Hammer Special Effect Bowling Ball

Looking for elite performance with explosive backend power? The Hammer Special Effect is your next-level weapon for challenging conditions.

As the upgraded evolution of the fan-favorite Hammer Effect, the Special Effect fuses classic core strength with modern cover innovation — giving bowlers a shiny ball that rolls early and finishes strong. The proven Huntsman Core returns, delivering a balanced blend of torque, control, and heavy hook potential that thrives under pressure.

But what really sets this one apart is the HK22 Cohesion Solid Reactive coverstock. With a 1500 Grit + Factory Compound finish, it creates exceptional mid-lane traction and a fierce backend reaction — perfect for medium to heavy oil conditions where sharp movement is essential.

Hammer built the Special Effect for high-performance players who want predictability in the early lane, aggression at the breakpoint, and a statement shot into the pocket. Finished in an electrifying mix of black, blue, purple, and red, this ball looks every bit as serious as it performs.
