It pairs the strong symmetric Tiered Hexagon Core with a harder 78D Urethane Solid coverstock, delivering controlled, predictable urethane motion with the flare of a strong core, for dry to medium oil and short patterns. It is a control specialist for the most demanding conditions.\n\nThe Crown 78U combines a strong reactive-style core with a urethane cover, an unusual and capable mix. The Tiered Hexagon core provides real flare, while the harder 78D urethane cover reads the lane gently and holds a controlled line where a reactive ball would over-hook. The result is a urethane that carries more shape than most, ideal when control matters but you still want some motion.\n\nUnderstanding the Brunswick Tiered Hexagon Core and Brunswick Urethane Solid 78D\n\nBrunswick built the Crown 78U for controlled urethane motion with the flare of a strong core. Specifically, the symmetric Tiered Hexagon Core posts a 2.540 RG and a strong .045 differential for real flare, while the harder 78D Urethane Solid cover at a 1000-grit finish reads the lane gently rather than snapping. As a result, it delivers a controlled, repeatable shape with more motion than most urethane on dry to medium oil. The per-weight specifications are listed below.\n\nA Strong Symmetric Core, Shared With the Crown Line\n\nAt the heart of the Crown 78U is the symmetric Tiered Hexagon Core, the same strong block used across the Crown line. At 15 lb it measures a 2.540 RG and a strong .045 differential, numbers that produce real flare for a controllable, continuous motion. Pairing that strong core with a urethane cover is what gives the Crown 78U more shape than a typical urethane.\n\nBrunswick wraps the Tiered Hexagon core in DynamiCore for added durability and a stronger hitting ball. The strong core provides the flare, while the urethane cover keeps the overall motion controlled and predictable.\n\nA Harder 78D Urethane Cover for Controlled, Predictable Motion\n\nThe Crown 78U wraps that strong core in a harder 78D Urethane Solid coverstock at a 1000-grit finish. Urethane generates less friction than reactive resin, so the ball reads the lane gently and holds a controlled line instead of snapping at the breakpoint. The harder 78D formulation adds even more control and length.\n\nThat combination of a strong core and a controlled urethane cover is what makes the Crown 78U unique: it carries more flare and shape than most urethane, but keeps the predictable, on-line motion that makes urethane so effective on short patterns and broken-down lanes. Take the surface down for a touch more grip, or smooth it up for more length, with surface changes done at your pro shop.\n\nCrown 78U Specs\n\nRG and differential vary by weight. Specifications provided by the manufacturer.\n\nWho This Ball Is Right For\n\n✓Control Players: A controlled urethane reaction with more flare than most, for dry, short, and broken-down lanes\n\n✓Short-Pattern Bowlers: Urethane control with the shape of a strong core for short patterns where a reactive ball over-reacts\n\n✓Urethane Users: A harder 78D urethane that holds its line but carries more motion than a typical urethane\n\n✓Arsenal Builders: A specialty control piece that bridges urethane control and reactive-style flare\n\nGood to Know Before You Buy\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·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 Crown 78U Fits in Your Brunswick Arsenal\n\nWhere It Fits in Your Arsenal\n\nIn the Brunswick lineup, the Crown 78U is a specialty control piece for dry, short, and broken-down lanes. Where your reactive Crown balls hook sharply, the 78D urethane Crown 78U reads smoothly and holds its line, but its strong core gives it more shape than a typical urethane. It is the ball you reach for when you want control with a little extra motion.\n\nSurface Adjustments\n\nThe 1000-grit finish gives the Crown 78U its controlled urethane read with grip. Take the surface lower for more traction on the driest lanes, or smooth it up for more length. Have surface changes done at your pro shop for an even, consistent finish.\n\nCoverstock Care\n\nWipe the urethane cover with an approved ball cleaner after every session. Keeping the cover fresh preserves the controlled, predictable read that makes the Crown 78U such a capable control piece.\n\nEarn points on every Brunswick purchase through the Striking Rewards loyalty program.
