The long anticipated addition to the Shift Series has just arrived and promises to go beyond Premier Line standards! Completely reconstructed, the new Gravity Shift sports the reformulated R2X coverstock - an enhanced version of it's predecessor the R2S - which uses special blends of materials to provide outstanding durability and exceptional performance. At the heart of the Gravity Shift is the new Shape-Lock HD (High Density) core. Increasing the density value and lowering the core volume effectively produces superior mid-lane roll and handling. The Gravity Shift produces outstanding performance in the ever-changing modern lane conditions and promises consistent ball reaction.

By the time your opponents' realize the Gravity of their situation...it'll be too late!

Storm Pro Pin Technology


PRO-PIN: A Pro-Pin is where the Pin distance from the CG is 5" - 6 ½” out. Although still categorized as a first quality ball it has limited drill options (see our Pro-Pin Drilling Options) that requires a certain type of bowler. Please consult your pro shop professional before purchasing one of these balls. Anything more than 6 ½” would be termed an X-Blem (second).
