The Storm Rocket A.I. brings back one of the most trusted names in the Thunder line, updated for today’s lane conditions. Known for its easy length and strong backend motion, the Rocket returns with added performance, giving bowlers a cleaner look through the front with more continuation downlane.

At the center is the Booster Core, now enhanced with A.I. Technology, which lowers RG and increases differential to create more dynamic motion and improved carry. Wrapped in the A1S Pearl Reactive cover, this ball provides clean length with a defined, responsive move at the breakpoint—making it ideal when the lanes start to dry out.

Compared to earlier Rocket releases, this version offers more continuation and forgiveness, helping maintain hitting power even on off-hits while still delivering that classic Thunder line shape bowlers trust.

Coverstock

A1S Pearl Reactive Coverstock - Engineered with Storm’s Adhesion System, this cover creates easy length through the front with strong responsiveness to friction, delivering a clean and controlled backend motion.

Core

Booster A.I. Core - A medium RG, medium differential symmetric design enhanced with A.I. Technology to increase flare potential and continuation, improving carry and overall motion on modern lane conditions.

When to Use

Speed Dominant - Ideal when you need help creating length and backend motion on drier lanes. The clean cover helps clear the fronts while still finishing strong.

Balanced - Best used during transition or on medium-dry conditions where stronger balls start reading too early. It allows you to open up angles while maintaining control.

Rev Dominant - A great option when friction is high and stronger equipment becomes too early. It provides added length with a defined backend without overreaction.

Arsenal Fit

Fits as a ball-down option in the Thunder line, sitting below stronger symmetrical pieces while providing added length and a responsive backend when the fronts start to go.
