Storm Hy-Road 40, released in 2025, pairs the A1S Pearl cover with a symmetric Inverted Fe2 core. It measures RG 2.52 and differential .058 — medium RG and high flare potential, banded on Storm's published scale. It leaves the factory at Power Edge.
Measured at 16 lb (no 15 lb measurement on record). These are box specs for an undrilled ball — drilling changes them.
The ReRack marketplace opens once enough balls are listed. List yours before it does and it keeps 0% seller commission for as long as it stays listed — the rate is written onto the listing when you create it and is never changed afterwards.

Brand vocabulary, not measurements — no two manufacturers use the same scale, so these never compare across brands.

These specs are factory reference for the model, compiled from manufacturer publications and other sources and provided as is. They may contain errors or describe a different production run, and they say nothing about the condition of any individual used ball — surface prep, resurfacing, plugging, and drilling all change how a ball behaves relative to its published numbers.

The Ball Finder matches your rev rate, speed, and lane condition against these specs. Buy and sell used on ReRack — your payment is held until the ball is delivered.
Closest on the three specs that compare across brands — RG, differential and symmetry. One ball per line, so no other version of the Hy-Road 40 appears here.
