The Release Valve Shim Kit increases the pressure needed to “pop off“ the pressure relief valve (PRV). This means that the available fuel rail pressure remains high during heavy engine loads and reduces the fuel flow through the fuel return system. The PPE Release Valve Shim Kit eliminates low fuel rail pressure DTC codes P1093 or P0087 (low fuel rail pressure during power enrichment) and is recommended for high performance and/or race applications.

Available for:

  • GM Duramax 2004.5 - 2010 LLY/LBZ/LMM
  • Dodge Cummins 2008-2010 6.7

*Note: Legal in California only for racing vehicles which may never be used on the highway.
