Strike King™ Black Pearl


The SK13 reactive coverstock describes our newest formulation for a low friction coverstock. The benefits of using our SK13 formula allows us to produce a less aggressive reactive coverstock that easily projects down the lane without making the coverstock highly sensitive to the dry and oily parts of the lane.


The new Strike King symmetrical core features a single density light bulb shape design. This core design promotes skid through the front and mid-lane with flip on the backend.

Ball Motion

With its High Gloss box finish, the Strike King will provide excellent length with a medium to quick response to friction at the breakpoint. The Strike King is great ball for entry level bowlers, rev dominant and slower ball speed players on light oil conditions.

Reaction Setup

The Strike King be drilled using the standard drilling techniques developed for symmetric bowling balls.

Lightweight Engineering

At Brunswick, the unique core shape of each individual ball is used for weights from 12 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across this weight range.
