Hammerhead Pearl
The Hammer Hammerhead Pearl is a pearl reactive bowling ball with the Spheroid core. RG 2.481 and differential 0.048 at 15 lb. For medium oil.
The Hammerhead made waves as a no-nonsense benchmark ball that delivers unbeatable value. Now, the line evolves. The Hammerhead Pearl attacks medium to broken-down lanes with explosive backend motion and the unmistakable Hammer attitude. When the bigger hooking balls start burning up or losing energy, this one keeps striking. Powered by the proven Spheroid core and HK22 – Aggression Pearl cover, the Hammerhead Pearl doesn’t just fill a gap—it owns it. This ball was built to dominate.
