BD Diesel 1036713 Positive Air Shut-Off for 2011-2016 Silverado/Sierra 6.6L Duramax

The BD Diesel Positive Air Shut-Off (PAS) provides critical protection against diesel engine runaway—a rare but dangerous condition where external hydrocarbons are drawn into the engine, causing uncontrolled overspeeding and potentially catastrophic engine failure. This emergency shutdown system safeguards your engine, vehicle, and personal safety by cutting the intake air supply to the cylinders and safely shutting down the engine within seconds.

Key Features:

• Butterfly valve design installs in-line in the air intake system for effective emergency shutdown
• Heavy-duty electrical solenoid trips a locked safety cam to stop the engine immediately
• Compact aluminum and stainless steel construction resists corrosion
• Weatherproof electrical connectors for reliable all-weather operation
• Bead boot lock installation—no welding required
• Includes automatic engine overspeed electronics for hands-free protection
• CAC (Charge Air Cooler) pipes included for complete installation
• Unique locking lever securely holds valve in position

Specifications:

• Application: 2011-2016 Chevrolet Silverado/GMC Sierra 6.6L Duramax diesel engines
• Installation Time: Approximately 3.5 hours
• Warranty: 24 months/24,000 miles on parts
• Emissions Compliance: Legal for sale and use in all 50 states (does not require California EO)

This simplified design reduces the number of components and overall size compared to competitive units, making installation easier while providing the most effective method for emergency engine shutdown—cutting off the air supply that diesel engines require to operate.
