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.\n\nThe 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.\n\nUnderstanding the Hammer Stacked LED Core and Hammer HK22 Cohesion Pearl Reactive\n\nHammer 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.\n\nA New LED-Family Symmetric Core Built for Length and a Strong Backend\n\nAt 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.\n\nAs 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).\n\nThe Black Widow 3.0 Dynasty Cover, in Pearl\n\nWrapping 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.\n\nThat 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.\n\nBlacklist Specs\n\nRG and differential vary by weight. Specifications provided by the manufacturer.\n\nWho This Ball Is Right For\n\n✓Speed-Dominant Players: The pearl cover and a .047 differential give extra backend when ball speed outruns the lane\n\n✓League Bowlers: A clean, easy-to-read transition ball for medium house shots\n\n✓Hammerhead Pearl Owners: A more defined, more angular step up for the same part of the bag\n\n✓Style-Minded Bowlers: An all-black ball with black logos that looks like nothing else in the Hammer lineup\n\nGood to Know Before You Buy\n\n·Ships polished: The 500, 1000, 1500 Siaair / Factory Compound finish runs clean and long out of the box. For an earlier read on heavier oil, take the surface down at your pro shop.\n\n·Colors vary: Actual colors vary somewhat from the photos shown; no two balls come out of the mold exactly alike.\n\n·Tiny pit holes are normal: A few tiny pit holes in the coverstock are a normal part of the manufacturing process.\n\n·Sold undrilled: Ships without finger holes, so it can be fitted to your hand and span.\n\nBowlersMart Tips: Where the Blacklist Fits in Your Hammer Arsenal\n\nWhere It Fits in Your Arsenal\n\nIn the Hammer lineup, the Blacklist is the clean, angular pearl for medium oil and transition. Hammer positions it as more defined than the Hammerhead Pearl and more angular and aggressive downlane than the Deep Ocean Vibe, so it slots between your benchmark and your cleanest backend ball.\n\nSurface Adjustments\n\nThe 500, 1000, 1500 Siaair / Factory Compound finish ships clean and long. Take the surface down at your pro shop for an earlier read when the oil is heavier, or keep it polished for maximum length. Have surface changes done at your pro shop for an even, consistent finish.\n\nCoverstock Care\n\nReactive covers absorb oil over time, which softens the reaction. Wipe the ball down after every set and deep clean it periodically so the HK22 Cohesion Pearl cover keeps the motion it shipped with.\n\nEarn points on every Hammer purchase through the Striking Rewards loyalty program. Every ball you add to your arsenal builds toward your next reward.\n\nShop With Confidence at BowlersMart\n\nThe Hammer Blacklist Bowling Ball ships free with no minimum purchase and is backed by our 60-day return policy.
