Master Engine Braking with Cummins 3871711 Solenoid Valve for Jake Brake Systems

Take control of engine braking performance with the Cummins 3871711 Solenoid Valve, distributed by Volgen Power. This essential component supports the Jake Brake system on ISM11, QSM11, and M11 engines, enabling precise braking control in heavy-duty trucks and construction machinery.

Engineered for Control

Weighing approximately 0.3 kg, this solenoid valve is a key actuator in the compression-release engine brake system. It activates the Jake Brake by regulating oil flow to the valve mechanism, allowing the exhaust valves to open at just the right moment for controlled engine deceleration. By reducing dependency on traditional service brakes, it helps prevent overheating and brake fade, critical in long-haul or downhill conditions.

Compatible with Major Cummins Platforms

Built to work seamlessly with Cummins 10.8L inline-6 engines, including:

• ISM11

• QSM11

• M11

These engines are widely used across applications such as:

• Class 8 trucks (e.g., Freightliner, Peterbilt, Kenworth)

• Construction and mining equipment (e.g., Hyundai excavators powered by QSM11)

Product Identification

• OEM Part Number: 3871711

• Alternate Listing: 3871711X (specifically for Jacobs brake systems)

• Function: Solenoid Valve for Jake Brake (engine compression braking system)

It is a direct-fit replacement that maintains the factory-calibrated brake timing and pressure required for dependable engine braking in critical scenarios.

Built for Demanding Environments

The Cummins 3871711 solenoid valve is built to meet OEM specifications, ensuring it delivers consistent performance in high-temperature, high-pressure environments. Whether navigating steep grades or carrying heavy payloads, this valve contributes to smoother deceleration and greater driver control.
