Hammer Maximum Effect Bowling Ball

You asked for more—Hammer delivered. The Maximum Effect is the boldest addition yet to the wildly popular Effect line, engineered to take the signature Effect motion to new extremes on heavier conditions. For the first time ever, Hammer has paired the HK22 – Cohesion coverstock with CFI (Carbon Fiber Infused) technology, a combination that produces unparalleled traction, strength, and durability. This breakthrough pairing allows the Maximum Effect to dig in where other balls fade, giving you the confidence to attack medium to heavy oil with authority.

With its aggressive 500/1500 grit finish, the Maximum Effect creates early bite and consistent motion without sacrificing backend continuation. Add in the striking four-color swirl design, and you get a ball that’s not only the strongest in the Effect lineup—it’s a statement piece on the lanes. Hammerheads wanted more teeth, more traction, and more Effect, and the Maximum Effect delivers it all.

This is Maximum performance, Maximum confidence—Maximum Effect.
