Hammer Blacklist Bowling Ball

Blacked Out, and Impossible to Ignore

About the Blacklist

The Hammer Blacklist is designed to stand out by not standing out. Its black pearl cover and black logos create a sleek, all-black look unlike anything else in the Hammer lineup, yet its performance is anything but subtle. It streets November 19, 2026.

The new Stacked LED core, inspired by Hammer’s popular LED core shapes, is paired with HK22 Cohesion Pearl, the pearl version of the coverstock used on the Black Widow 3.0 Dynasty, at a 500, 1000, 1500 Siaair / Factory Compound finish. The result is easy length and a strong response to friction: a clean, angular motion with a strong, continuous backend, more defined than the Hammerhead Pearl and more angular and aggressive downlane than the Deep Ocean Vibe.

Understanding the Hammer Stacked LED Core and Hammer HK22 Cohesion Pearl Reactive

Hammer built the Blacklist for medium oil and a skid/flip reaction. Specifically, the symmetric Stacked LED core measures a 2.545 RG with a .047 differential at 15 lb, enough flare for a strong backend without an early read, while the HK22 Cohesion Pearl cover at a 500, 1000, 1500 Siaair / Factory Compound finish clears the front for easy length. The 13 and 12 lb weights use a dedicated core (2.585 RG, .040 differential at 13 lb). The full per-weight numbers are listed below.

A New LED-Family Symmetric Core Built for Length and a Strong Backend

At the heart of the Blacklist is the new Stacked LED core, inspired by the LED core shapes Hammer fans already know. At 15 lb it measures a 2.545 RG and a .047 differential. The medium-high RG helps the ball conserve energy through the front of the lane, and the differential gives it the flare to turn hard once it finds friction.

As a symmetric core it reads the lane predictably and repeats its shape shot after shot, which suits the Blacklist’s job: easy length, then a clean, defined move at the breakpoint. The 13 and 12 lb weights carry a dedicated core tuned for those weights (2.585 RG, .040 differential at 13 lb).

The Black Widow 3.0 Dynasty Cover, in Pearl

Wrapping the Stacked LED core is HK22 Cohesion Pearl, the pearl version of the coverstock on the Black Widow 3.0 Dynasty. It ships at a 500, 1000, 1500 Siaair / Factory Compound finish, a clean, polished box surface that lets the ball skid through the front and store energy for the backend.

That pearl cover is what gives the Blacklist its skid/flip character. It gets down the lane easily, then responds strongly to friction for a clean, angular change of direction and a continuous finish through the pins.
