Stealth Mode: The Benchmark Ball Reborn
Introducing the Track Stealth Mode: The Evolution of a Benchmark Ball
The Track Stealth Mode bowling ball is a highly anticipated release, designed as an evolution of the original Stealth, a ball that was known for its versatility. This new release maintains the original Stealth core, but features an upgraded QR-10 coverstock. The Stealth Mode is intended to be a benchmark-style ball, suitable for a wide range of bowling styles, and strong enough to be a bowler’s first ball out of the bag. The QR-10 coverstock is designed to offer a touch more performance than the original Stealth, making it a new standard in benchmark ball reaction from Track. It is intended to provide bowlers with a strong mid-lane and backend reaction, as well as great versatility on the lanes.
The Track Stealth Mode also incorporates DynamiCore technology, which is an innovation in outer core technology developed by Brunswick Bowling Products. This technology provides a more durable outer material that yields less compression upon impact, increasing hitting power and pin carry. The ball is available in weights from 12 to 16 pounds and is designed for medium to heavy oil lane conditions. The Stealth Mode is set to be released on February 20, 2025. Track has created the Stealth Mode to be a go-to bowling ball for its versatility, while remaining true to the original Stealth design. The Stealth Mode is the ball Track fans have been requesting.
The Core of the Track Stealth Mode: A Legacy of Performance
The Track Stealth Mode bowling ball features the original Stealth core, which is a key element in maintaining the ball’s benchmark-style reaction. Track has chosen to keep the original core to not deviate from the line’s success. The core’s design is intended to provide a consistent and versatile reaction, making it suitable for a wide range of bowling styles. The core is designed to create a strong mid-lane and backend reaction. The RG and differential numbers vary slightly based on the weight of the ball. For example, a 16 lb ball has an RG of 2.498 and a differential of 0.048, while a 15 lb ball has an RG of 2.482 and a differential of 0.056. The core’s design, in combination with the upgraded coverstock, is intended to make the Stealth Mode a reliable and consistent option for bowlers.
The Stealth core, combined with the QR-10 coverstock and DynamiCore technology, contributes to the ball’s overall performance. The core numbers indicate that the Stealth Mode is designed to have a controlled and predictable motion on the lanes. The symmetric core is designed to provide a balance of stability and responsiveness, allowing the ball to maintain its energy through the front part of the lane and react strongly on the backend. The core’s design is a key factor in the ball’s versatility, allowing it to be used effectively on medium to heavy oil lane conditions. The use of the original Stealth core is intended to appeal to bowlers who enjoyed the reaction of the original ball, while the updated coverstock and outer core technology are intended to improve on that performance.

Unleash the QR-10: Enhanced Performance in the Stealth Mode

The Factory Finish of the Track Stealth Mode: Ready to Perform
The Track Stealth Mode bowling ball is finished with a 500, 1500 Siaair Micro Pad at the factory. This finish is designed to provide a balanced reaction straight out of the box, making it suitable for a variety of bowlers. The Siaair Micro Pad is a high-quality abrasive that ensures a consistent surface texture, which is essential for the ball’s overall predictability on the lanes. The factory finish is intended to optimize the ball’s performance for medium to heavy oil lane conditions. This allows bowlers to use the Stealth Mode immediately upon purchase, without needing to make surface adjustments before hitting the lanes, although surface adjustments can still be made for personal preference or to match specific lane conditions.
The factory finish is a crucial element of the Stealth Mode’s overall design, as it works in tandem with the QR-10 coverstock and the original Stealth core to create the ball’s versatile and strong reaction. The 500, 1500 Siaair Micro Pad finish provides a balanced amount of traction in the oil and responsiveness to friction, allowing the ball to perform consistently on various lane conditions. While the ball is designed to perform well with its factory finish, bowlers have the option to alter the surface to better suit their individual style or the specific lane conditions they encounter. The Stealth Mode’s factory finish is intended to provide a reliable and predictable reaction for a wide variety of bowlers.
