BD Diesel Electronic Positive Air Shutdown (E-PAS)

2025 Ram 2500/3500 6.7L Diesel

Part #: 1036766

Overview

The BD Diesel Electronic Positive Air Shutdown (E-PAS) is a critical safety device designed to protect your diesel engine from runaway conditions. Diesel engine runaway occurs when external hydrocarbons enter the engine, causing it to overspeed uncontrollably, which can lead to catastrophic engine failure and serious safety hazards. The E-PAS system acts like an emergency shutoff, cutting the intake air supply to the engine cylinders and safely shutting down the engine to prevent damage and danger.

Specifically engineered for the 2025 Ram 2500 and 3500 equipped with the 6.7L Cummins diesel engine, this unit provides peace of mind for diesel truck owners who demand reliable protection against rare but potentially devastating engine runaway events. Easy to install and designed to integrate seamlessly with the factory electronic throttle body, the BD Diesel E-PAS is an essential safeguard for your investment and safety.
