The front and rear shocks are direct bolt in pieces utilizing Hyperco springs.  The Hyperco springs eliminate spring sagging and the need to re-adjust ride height and corner weights.  The use of thrust washers will maximize grip by taking the friction out of the springs as they compress.  We reuse the stock, rear lower fork, which threads directly onto the JRi shock body cap.  The JRi Shocks provide the largest range of adjustment on the market.  This adjustment range is ideal for tuning your shocks to the track and any track condition.
