SWAG Bowling Ball Cores

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

SWAG puts 12 different cores into the 24 SWAG balls we have in stock today: 7 symmetric and 5 asymmetric. The newest is the SWAG Insanity Symmetric Core. The strongest flare comes from the SWAG Guillotine Asymmetric Core (differential 0.053), and the earliest-revving is the SWAG Dragon Asymmetric Core (RG 2.490). Every core below links to its own page with specs by weight and the balls built on it.

Questions bowlers ask

What cores does SWAG use in its bowling balls?

12 different cores are in the SWAG balls we stock today: Craze Core, Dragon Asymmetric Core, Fusion Core, APX V1 Core, Insanity Symmetric Core, Judge Core, Unreal Core, Assassin Core and others. 7 are symmetric and 5 asymmetric. Each core’s page lists its RG, differential and mass bias by weight.

Which SWAG core has the most flare?

The SWAG Guillotine Asymmetric Core, with a differential of 0.053 at 15 lb, the highest of the SWAG cores in stock. Higher differential means more flare potential and a stronger, more angular motion.

Which SWAG core revs up earliest?

The SWAG Dragon Asymmetric Core, with an RG of 2.490 at 15 lb, the lowest of the SWAG cores in stock. A low RG core starts revving sooner and reads the midlane earlier.

Are SWAG cores symmetric or asymmetric?

Both. Of the 12 SWAG cores in stock, 7 are symmetric (one pin marker, a smooth continuous arc) and 5 are asymmetric (pin and PSA markers, a stronger and more angular backend).

What is SWAG’s newest core?

The SWAG Insanity Symmetric Core, first sold here in July 2026. It is symmetric with an RG of 2.520 and a differential of 0.034 at 15 lb.
