Make the switch to Volvik and experience the exceptional performance of the VOLVIK S4 — a four-piece BISMUTH Dual Core Tour Ball engineered specifically for players with high swing speeds. The S4 has been developed to deliver greater precision, a higher ball flight, and increased distance, allowing it to compete with the very best Tour balls on the market. The patented VU-X Urethane cover provides an outstandingly responsive feel at impact and elevated greenside spin, working in perfect harmony with the resilience of the bismuth-enhanced core. If you are a high swing-speed player (95–120 mph) who demands world-class performance from every golf ball, the Volvik S4 is the definitive choice.
At the heart of the Volvik S4 lies its groundbreaking BISMUTH Dual Core technology — a four-piece construction that sets it apart from conventional Tour balls. Bismuth is an exceptionally rare and dense heavy metal; Volvik embeds it into the outer core to dramatically increase energy transfer efficiency at the moment of impact. Unlike normal metals, bismuth expands approximately 3.5% in volume upon impact, providing a unique springlike effect that drives explosive ball speed. This placement toward the outside of the ball also increases the moment of inertia (MOI), generating better lift, greater carry distance, and the shot-shaping control that skilled players demand.
The S4 takes an innovative approach to dual core architecture that is opposite to most Tour-level balls. Rather than transferring inertia from a soft inner core to a solid outer layer, Volvik combines a more solid inner core with a softer outer core layer. This means power is transferred outward from the firm centre through the progressively softer outer core, generating a higher launch angle with reduced driver spin — the ideal performance profile for players who generate high clubhead speeds. The result is a ball that launches high and pierces the air efficiently, adding yards to every tee shot without sacrificing control.
The VU-X Urethane cover is Volvik's proprietary formulation, engineered to deliver the soft, responsive feel demanded by Tour professionals while providing industry-leading durability. A unique coating process optimises spin rates across all shot types, producing low spin off the driver for maximum distance and high spin with short irons and wedges for precise approach play and greenside control. The cover's inherent toughness resists scuffing and maintains its performance characteristics round after round, meaning you can trust your S4 to deliver consistent results throughout an entire season of competitive golf.
Every aspect of the Volvik S4's flight performance has been refined through the patented 336-dimple design. The precisely calculated dimple geometry reduces aerodynamic drag during the initial high-speed phase of flight, then maintains optimal lift throughout the descent to produce a penetrating, consistent ball flight. Whether you are playing in still air or challenging crosswinds, the 336-dimple pattern keeps the S4 on its intended trajectory, shot after shot. The result is a tight dispersion pattern that gives high-swing-speed players the confidence to attack pins even from long distances.
