The Hy-Road 40 celebrates four decades of Storm innovation by continuing the legacy of one of the most trusted names in bowling. At its core lies the legendary Inverted Fe² Technology—Storm’s most successful weight block design—delivering unmatched energy retention and dynamic hitting power. Wrapped in the successful A1S Pearl coverstock—first debuted on the Equinox and known as one of the fastest oil-absorbing materials in our lineup—the Hy-Road 40 maintains a consistent reaction shot after shot, especially in heavier conditions where oil buildup can compromise performance. The Hy-Road 40 is a tribute to where we’ve been—and a bold step toward where you’re headed.
Inverted Fe2 technology boasts a higher RG and differential like most other balls in the Thunder Line, but with one very important benefit: it lacks the core material that most other balls have. This enables the ball to have a much thicker shell which raises the coefficient of restitution. A higher energy transfer to the pins with less deflection upon impact is what can be expected with this design.
