Description

PPE Release Valve Shim Kit

2008–2010 Dodge Ram 6.7L Diesel

Part #: 113072000

The PPE Release Valve Shim Kit is a precision-engineered upgrade designed specifically for the fuel system of 2008 to 2010 Dodge Ram trucks equipped with the 6.7L Cummins diesel engine. This kit increases the pressure threshold required to activate the pressure relief valve (PRV), ensuring the fuel rail pressure remains elevated during demanding driving conditions such as full-throttle acceleration and heavy load operation.

Over time, factory fuel return springs can weaken, causing premature activation of the pressure relief valve and resulting in reduced fuel rail pressure. This can trigger diagnostic trouble codes (DTCs) like P1093 and P0087, which indicate low fuel rail pressure during power enrichment. The PPE shim kit addresses these issues by maintaining consistent fuel pressure, improving fuel delivery reliability and engine performance.

Ideal for Dodge Ram owners who want to optimize their truck’s fuel system performance and prevent common low-pressure faults, this kit offers a simple and effective solution without requiring permanent modifications.

Key Features

The PPE Release Valve Shim Kit provides a straightforward upgrade to enhance fuel rail pressure management. Key features include:

• Increases the pressure required to open the pressure relief valve, maintaining optimal fuel rail pressure under load.
• 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 tension.
• Recommended installation of two shims for optimal pressure control and consistent performance.
• Precision-manufactured for a perfect fit on 2008–2010 Dodge Ram 6.7L diesel models.
• Constructed from durable, corrosion-resistant materials designed to withstand high fuel system pressures and temperatures.
• Simple installation process requiring no permanent modifications to the fuel system.
• 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 demanding environment of the diesel fuel system. Each shim is manufactured to exact thickness specifications, ensuring precise and reliable adjustment of the pressure relief valve’s activation point.

The design focuses on durability and longevity, providing a stable solution that compensates for spring fatigue or wear over time. This ensures the fuel rail pressure remains consistent, supporting optimal engine performance and preventing premature valve activation.

Installation & Fitment

Installation of the PPE Release Valve Shim Kit is straightforward and designed to fit directly onto the pressure relief valve assembly of 2008–2010 Dodge Ram trucks with the 6.7L Cummins diesel engine. No permanent modifications to the fuel system are required, making it a clean and reversible upgrade.

For best results, PPE recommends installing two shims to achieve the desired increase in spring pressure. This kit is suitable 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 6.7L diesel owners experiencing 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.
