Fuel Rail Shim Kit for Dodge 6.7 diesel engines. Eliminates unwanted pressure relief of fuel rail when running a high performance tuning device.  H&S Performance programming raises the fuel rail pressure and may cause the fuel rail release valve to open, causing trouble codes P0087 and P1011. The shims will eliminate the valve, allowing ample pressure to the rail and injectors, all without worry of losing rail pressure or trouble codes.
