Angled Wedge Shock Pads were originally produced in the 1970s and called RadPads. By mounting your trucks on top of these Angled Risers, you can either increase or decrease how your trucks turn by changing the geometry of the KingPin and Pivot Point. To make your trucks turn MORE, position these Angled Wedge Shock Pads under your trucks with the thick side facing the center of your board.
