ShockerPASS is a purpose-built diesel engine safety system designed to prevent runaway events and protect equipment, operators, and worksites in high-risk environments. Developed as a positive air shutoff solution, ShockerPASS delivers fast, reliable air intake closure when engine overspeed occurs—stopping catastrophic failures before they happen.
Diesel engine runaway can occur without warning and escalate quickly, leading to severe equipment damage, fire risk, or injury. ShockerPASS is designed to intervene at the most critical moment by immediately cutting off the engine’s air supply when unsafe RPM levels are reached. By removing oxygen from the combustion process, the system brings the engine to a controlled stop—regardless of fuel source.
ShockerPASS instantly cuts off the engine air supply during overspeed events, stopping runways before damage or danger occurs.
Designed to perform reliably in extreme conditions, ShockerPASS is built for operations where failure is not an option.
Available in manual and RPM-controlled automatic configurations to suit operator-driven or autonomous equipment.
Machined from Billet 6061 aluminum, ShockerPASS is built for long-term durability, corrosion resistance, and vibration tolerance.
