BD Diesel E-PAS Positive Air Shut-Off 17-23 GM 6.6L Duramax L5P

Be ready when it matters most with the BD Diesel E-PAS Positive Air Shut-Off for your 2017–2023 GM 6.6L Duramax L5P.

Diesel engine runaways are rare, but when they happen, the consequences can be devastating. BD Diesel’s E-PAS is your insurance policy against uncontrolled overspeed situations caused by external hydrocarbons (like oil from a bad turbo seal). Unlike traditional mechanical shut-off systems, the E-PAS takes advantage of your engine’s existing electronic throttle body, safely shutting off airflow in emergencies, without triggering a Malfunction Indicator Light or codes like P0106. It’s the only Duramax specific system on the market that does this without lighting up your dash. Installation is quick and painless. With factory plug-in connectors and a pre-made wiring harness, you can have the whole system in and running in under 2 hours. That’s a full three hours of labor saved compared to mechanical alternatives. The only part that requires a tool is the switch itself. Once installed, the system automatically resets after shutdown, and if you need to remove it for a lease return or swap, that’s just as easy. It’s also IP67-rated for water and dust resistance, so it’s built to handle real-world conditions.

The E-PAS is a smart, seamless way to add an extra layer of safety to your Duramax, keeping both your truck and your peace of mind intact.
