Hammer Blacklist Bowling Ball

IMPOSSIBLE TO IGNORE. All Black. Maximum Attitude.

Some bowling balls demand attention with bold colors. The Hammer Blacklist Bowling Ball takes the opposite approach. Featuring a sleek Black Pearl coverstock with black logos, the Blacklist delivers a distinctive blacked-out appearance while producing an aggressive, attention-grabbing reaction on the lanes.

This is a pre-order bowling ball. It will ship on the release date.

Designed for medium oil lane conditions, the Hammer Blacklist combines the newly developed Stacked LED core with HK22 – Cohesion Pearl Reactive coverstock to create easy length, a strong response to friction, and a powerful, continuous backend motion.

The result is a clean, angular skid-flip bowling ball that travels efficiently through the front of the lane before making a decisive move toward the pocket.

Hammer designed the Blacklist to deliver a more defined reaction than the Hammerhead Pearl and a more angular, aggressive downlane response than the Deep Ocean Vibe.

With a 15 lb RG of 2.545 and differential of 0.047, the Blacklist combines a versatile core design with substantial flare potential, making it an excellent option for bowlers seeking backend strength without sacrificing front-lane length.

Whether you're searching for a pearl reactive bowling ball for medium oil, a strong backend bowling ball, or a high-performance black bowling ball that looks as impressive as it performs, the Hammer Blacklist delivers.

Stacked LED Core – Engineered for Length and Backend Performance

At the heart of the Hammer Blacklist is the all-new Stacked LED core, inspired by the popular LED core shapes found in Hammer's previous bowling ball designs.

Engineered to complement the HK22 – Cohesion Pearl coverstock, the Stacked LED core supports the clean, angular motion that defines the Blacklist.

Featuring a 15 lb RG of 2.545 and differential of 0.047, the core provides a combination of rotational characteristics and flare potential suited to medium oil conditions.

The RG contributes to the ball's ability to travel through the front of the lane before developing its strongest reaction, while the differential influences track flare potential.

Together, these characteristics help the Blacklist maintain length while generating a strong response as it encounters friction downlane.

For bowlers looking for a medium oil bowling ball with strong backend reaction and reliable continuation, the Stacked LED core provides the foundation for an aggressive yet versatile performance profile.

HK22 – Cohesion Pearl Reactive Coverstock – Clean Length, Powerful Response

The HK22 – Cohesion Pearl Reactive coverstock is one of the defining performance features of the Hammer Blacklist.

Hammer developed the Blacklist using the pearl version of the coverstock technology found on the Black Widow 3.0 Dynasty, creating a different reaction shape suited to medium oil conditions.

The pearl reactive formulation is designed to travel cleanly through the front portion of the lane before responding strongly to friction.
