Roto Grip Rockstar Amped

This isn’t just a bowling ball—it’s an all-out surge of power, precision, and rock-fueled attitude. Engineered for bowlers who want every shot to bring down the house, the Roto Grip Rockstar Amped brings a new level of energy to the lanes. At its core is the Rocker + A.I. Core Technology, the driving force that delivers high-revving, aggressive motion and raw, untamed power through the pins. Pair that with the all-new NanoStar Pearl Reactive coverstock, featuring a medium load of nanoparticles blended throughout, and you’ve got a ball that clears the fronts with ease, reads the midlane with authority, and unleashes an amped-up backend reaction that’s clean and responsive—never erratic. Finished with Power Edge, this pearl symmetric powerhouse is tuned for medium to medium/heavy oil conditions. It shines when asymmetrical balls are too strong and weaker pieces just won’t cut it—blending out over/under and taming fresh, overactive patterns with rock-solid consistency. Like the original Rockstar, the Amped is built to perform on both house and tournament conditions, but with even more edge and attitude. This isn’t a quiet acoustic set—it’s a wall of sound designed to grip the lane like a guitar solo grips your soul.
