A Strong, Controllable Symmetric Solid for Medium to Heavy Oil
About the Danger Zone
The Brunswick Danger Zone revives a classic Brunswick name with a strong, controllable symmetric motion. It pairs the symmetric Danger Zone Core with the HK22 PowerKoil 26 solid coverstock, delivering an early, even read with real hooking strength on medium to heavy oil. It is an easy-to-read benchmark that reads the lane and drives through the pins.
The Danger Zone gives you benchmark strength in a smooth, symmetric package. The Danger Zone core rolls smooth and even, while the HK22 PowerKoil 26 solid cover reads the midlane early. The result is a controllable, continuous hook without the sharp backend of an asymmetric, a dependable medium-to-heavy-oil piece that hooks more than its smooth roll suggests.
Understanding the Brunswick Danger Zone Core and Brunswick HK22 PowerKoil 26 Solid Reactive
Brunswick built the Danger Zone for a strong, controllable symmetric read on medium to heavy oil. Specifically, the symmetric Danger Zone Core posts a 2.501 RG and a strong .048 differential, numbers that produce an early roll with high flare for a symmetric ball, while the HK22 PowerKoil 26 solid cover reads the midlane and drives through the pins. As a result, it gives you benchmark strength with a controllable, continuous motion. The per-weight specifications are listed below.
A Strong Symmetric Core for Flare and an Early Roll
At the heart of the Danger Zone is the symmetric Danger Zone Core. At 15 lb it measures a 2.501 RG and a strong .048 differential, numbers that produce an early roll with high flare for a symmetric ball. The strong differential gives it real hooking strength while the symmetric design keeps the reaction predictable and easy to repeat.
Brunswick wraps the Danger Zone core in DynamiCore for added durability and a stronger hitting ball. That combination of strength and control is what makes the Danger Zone a benchmark: it hooks more than its smooth roll suggests, but it reads the lane the same way every shot.
An HK22 PowerKoil Solid That Reads the Midlane Early
The Danger Zone wraps that core in Brunswick’s HK22 PowerKoil 26 Solid Reactive coverstock at a polished finish. The PowerKoil solid reads the midlane early with strong traction, so the ball gets into a roll on medium to heavy oil and makes a controllable, continuous move through the pins.
That early, even read is what makes the Danger Zone such a dependable benchmark. Leave it at the box finish for medium to heavy oil, take the surface lower for more traction when the volume climbs, or polish it up for a cleaner, longer look when the lanes dry. Have surface changes done at your pro shop for an even, consistent finish.

BowlersMart Tips: Where the Danger Zone Fits in Your Brunswick Arsenal
Where It Fits in Your Arsenal
In the Brunswick lineup, the Danger Zone is the strong, controllable symmetric solid benchmark for medium to heavy oil. It shares the Danger Zone core with the Danger Zone Purple Ice pearl, reading earlier and stronger than the pearl. Throw the Danger Zone on fresh oil, then move to the Purple Ice for more length as the lane transitions.
Surface Adjustments
The polished finish gives the Danger Zone its strong, controllable read. Take the surface down with a lower-grit pad for an earlier, stronger read on more oil, or keep it polished for length when the lanes dry. Have surface changes done at your pro shop for an even, consistent finish.
Coverstock Care
Wipe the HK22 PowerKoil cover with an approved reactive ball cleaner after every session, and deep clean it periodically. Keeping the cover fresh preserves the strong, controllable read that makes the Danger Zone such a dependable benchmark.
