It pairs the asymmetric Gauntlet Core with the HK22C2 Solid coverstock at a coarse finish, delivering big flare and an early, hard-driving read on medium to heavy oil. It is a heavy-oil workhorse for bowlers who need early traction and strong drive.\n\nThe Spawn reads early and rolls strong. The asymmetric Gauntlet core stores energy for a defined breakpoint, while the HK22C2 Solid cover at a 1000-grit finish grabs the midlane hard. The result is a strong, controllable hook that gets into a roll quickly, ideal for fresh, heavy oil.\n\nUnderstanding the Hammer Gauntlet Core and Hammer HK22C2 Solid Reactive\n\nHammer built the Spawn for a strong, early read on medium to heavy oil. Specifically, the asymmetric Gauntlet Core posts a 2.501 RG, a strong .050 differential, and a .012 intermediate differential, numbers that produce high flare and an early, defined breakpoint, while the HK22C2 Solid cover at a 1000-grit finish reads the midlane early and drives through the pins. As a result, it gives you strong, early traction with a continuous backend. The per-weight specifications are listed below.\n\nA Strong Asymmetric Core for Early Roll and Flare\n\nAt the heart of the Spawn is the asymmetric Gauntlet Core. At 15 lb it measures a 2.501 RG, a strong .050 differential, and a .012 intermediate differential, a combination that produces high track flare and an early, defined breakpoint. The strong differential gives the ball the flare to clear heavy oil while the asymmetric design adds a defined move at the spot.\n\nBecause the Gauntlet core is asymmetric, layout has a strong influence on the reaction, so your pro shop can tune the pin and intermediate differential to control how early and how strong the Spawn plays.\n\nA Coarse HK22C2 Solid That Digs Into Heavy Oil\n\nThe Spawn wraps that core in Hammer's HK22C2 Solid Reactive coverstock at a coarse 1000-grit finish. The premium HK22C2 solid and aggressive sanded surface grab the midlane early, so the ball gets into a strong roll on heavy oil and drives continuously through the pins rather than skidding too far down the lane.\n\nThat early, traction-first read paired with the strong Gauntlet core is what makes the Spawn a heavy-oil workhorse: it digs in on real volume and keeps driving. Leave it at the 1000-grit box finish for maximum traction on heavy oil, or polish it up at your pro shop for a cleaner, longer read as the lanes transition.\n\nSpawn Specs\n\nRG and differential vary by weight. Specifications provided by the manufacturer.\n\nWho This Ball Is Right For\n\n✓Tournament Players: A strong, early-reading asymmetric for heavy fresh oil\n\n✓Higher-Rev Bowlers: The strong Gauntlet core and coarse HK22C2 solid reward revs with an early, continuous breakpoint\n\n✓Power Players: Early roll and high flare to clear heavy oil and keep driving through the pins\n\n✓Arsenal Builders: The early-reading heavy-oil piece, the strong solid at the top of the bag\n\nGood to Know Before You Buy\n\n·Strong, aggressive motion: This is a high-flare piece built for traction. If you want a controlled, lower-hook reaction, a lower-differential ball will suit you better.\n\n·Ships sanded for traction: The 1000 Grit finish is built to grip in oil. Polish it for more length when the volume drops.\n\n·Asymmetric layout sensitivity: Layout choices shift the reaction more than on a symmetric ball. Match the pin and mass bias to your game with 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 Spawn Fits in Your Hammer Arsenal\n\nWhere It Fits in Your Arsenal\n\nIn the Hammer lineup, the Spawn is the strong, early-reading heavy-oil piece. Its coarse 1000-grit cover digs in sooner than most of the line, so it is the ball you start with on fresh, heavy oil. Move to the Effect line or a pearl for more length as the lane transitions.\n\nSurface Adjustments\n\nThe 1000-grit finish gives the Spawn its early, strong read and heavy-oil traction. Keep it sanded for maximum grip, or polish it up at your pro shop for more length when the volume drops. Have surface changes done by a professional for an even, consistent finish.\n\nCoverstock Care\n\nWipe the HK22C2 Solid cover with an approved reactive ball cleaner after every session, and deep clean it periodically. A coarse-sanded solid like the Spawn relies on a fresh, clean surface to keep digging into oil.\n\nEarn points on every Hammer purchase through the Striking Rewards loyalty program.
