Hammer Bowling Ball Cores

Every Hammer core in a ball we sell, with its RG, differential and mass bias, on one map

Hammer puts 17 different cores into the 42 Hammer balls we have in stock today: 8 symmetric and 9 asymmetric. The newest is the Hammer Stacked LED Core. The strongest flare comes from the Hammer Gas Mask Core (differential 0.058), and the earliest-revving is the Hammer Obsession Tour Core (RG 2.469). Every core below links to its own page with specs by weight and the balls built on it.

Questions bowlers ask

What cores does Hammer use in its bowling balls?

17 different cores are in the Hammer balls we stock today: Gas Mask Core, Raw Hammer Core, Vibe Core, Super Offset Core, Huntsman Core, LED Core, Aftermath Core, Gas Mask Low Diff Core and others. 8 are symmetric and 9 asymmetric. Each core’s page lists its RG, differential and mass bias by weight.

Which Hammer core has the most flare?

The Hammer Gas Mask Core, with a differential of 0.058 at 15 lb, the highest of the Hammer cores in stock. Higher differential means more flare potential and a stronger, more angular motion.

Which Hammer core revs up earliest?

The Hammer Obsession Tour Core, with an RG of 2.469 at 15 lb, the lowest of the Hammer cores in stock. A low RG core starts revving sooner and reads the midlane earlier.

Are Hammer cores symmetric or asymmetric?

Both. Of the 17 Hammer cores in stock, 8 are symmetric (one pin marker, a smooth continuous arc) and 9 are asymmetric (pin and PSA markers, a stronger and more angular backend).

What is Hammer’s newest core?

The Hammer Stacked LED Core, first sold here in October 2026. It is symmetric with an RG of 2.545 and a differential of 0.047 at 15 lb.
