Storm Equinox Bowling Ball

Ready to dominate league nights? The Storm Equinox is your next-level performance ball, made for serious bowlers who demand backend power and control.

Purpose-built for league and weekend warriors, the Equinox is tuned for medium to heavy oil patterns—especially those in the 39–44 ft range that dominate competitive play. It delivers that signature Storm backend motion with a blend of power and precision you can count on.

At the core is Storm’s all-new Solarion A.I. Core, an asymmetrical design featuring three strategically placed cylinders. The central mass lowers the RG (2.48) for a quick revving action, while the top cylinder improves drilling flexibility. The lightweight base increases torque and creates a strong continuation through the pins. A .054 differential and .018 mass bias add aggressive flare and high-powered motion.

On the surface, the A1S Pearl Reactive coverstock debuts Storm’s Adhesion System Technology, designed to grip the lane with advanced tackiness. Combined with the Power Edge Polish finish, it delivers easy length with a crisp, angular move at the breakpoint—ideal for those looking to open up the lane and finish strong.
