PPE Release Valve Shim Kit

2008–2009 Dodge Ram

113072000

Overview:

The PPE Release Valve Shim Kit is a precision-engineered upgrade designed specifically for the 2008–2009 Dodge Ram fuel system. It increases the pressure threshold required to activate the pressure relief valve (PRV), ensuring that fuel rail pressure remains elevated as demanded by the engine computer during full-throttle operation. This enhancement is particularly beneficial for trucks experiencing weakened fuel return springs due to age or wear, which can cause premature valve activation and reduced fuel rail pressure.

By maintaining higher fuel rail pressure, the shim kit helps eliminate common diagnostic trouble codes (DTCs) such as P1093 and P0087, which indicate low fuel rail pressure during power enrichment. This product is ideal for Dodge Ram owners seeking to optimize fuel delivery reliability and engine performance under demanding driving conditions.

Key Features:

The PPE Release Valve Shim Kit offers a straightforward yet effective solution to fuel pressure management issues. Key features include:

• Increases the pressure required to open the pressure relief valve, maintaining optimal fuel rail pressure.
• Reduces excessive fuel flow through the return system caused by weakened factory springs.
• Helps prevent low fuel rail pressure DTC codes P1093 and P0087 related to insufficient PRV spring pressure.
• Recommended installation of two shims for optimal performance and pressure control.
• Precision-manufactured for a perfect fit on 2008–2009 Dodge Ram models.
• Durable materials designed to withstand high fuel system pressures and temperatures.
• Simple installation with no permanent modifications required.
• Improves fuel system consistency during full-throttle and power enrichment conditions.

Construction & Design:

The Release Valve Shim Kit is crafted from high-quality, corrosion-resistant materials engineered to endure the harsh environment of the fuel system. Each shim is precisely manufactured to exact thickness specifications, ensuring consistent and reliable pressure adjustment without compromising the integrity of the pressure relief valve assembly. The design focuses on durability and longevity, providing a stable solution that maintains fuel rail pressure over time despite spring fatigue or wear.

Installation & Fitment:

Installation of the PPE Release Valve Shim Kit is straightforward and requires no permanent modifications to the fuel system. It is designed to fit directly onto the pressure relief valve assembly of 2008–2009 Dodge Ram trucks. For best results, PPE recommends installing two shims to achieve the desired increase in spring pressure. This kit is ideal for professional installers or knowledgeable enthusiasts comfortable with basic fuel system service procedures.

What's Included:

• Two precision-engineered release valve shims
• Installation instructions

Ideal For:

This shim kit is perfect for Dodge Ram owners who experience low fuel rail pressure issues, especially those who frequently operate their trucks at full throttle or under heavy load conditions. It is also an excellent upgrade for vehicles with aging fuel system components where the original pressure relief valve spring has weakened, causing inconsistent fuel delivery and triggering low-pressure fault codes.
