PPE Release Valve Shim Kit

Fits: 2004.5-2010 Duramax LLY/LBZ/LMM
Our Part # 1130720
PPE Part # PPE1130720
free shipping
The shim kit effectively alters the spring tension in the pressure relief valve (PRV) increasing its “pop off” pressure, reducing fuel flow through the fuel rail return system. Eliminates low fuel rail pressure diagnostic trouble codes (DTC) P1093 or P0087 (low fuel rail pressure during power enrichment). Helps maintain fuel rail pressure during full-throttle driving. Recommended for performance or race applications.

Available for 2004.5-2010 Duramax (LLY/LBZ/LMM).
