Rugged Emissions Control: MI‑Jack Cummins ISB 6.7 L DEF Head Unit
What is it?
The MI‑Jack Cummins ISB 6.7 L DEF Head Unit is a high-performance emissions control module used in MI‑Jack industrial lifting and railcar-moving equipment powered by Cummins ISB 6.7 L engines. It precisely meters Diesel Exhaust Fluid (DEF) into the exhaust stream to neutralize nitrogen oxides (NOx), with built-in sensors monitoring fluid level, temperature, and pressure for reliable SCR system operation—even in demanding industrial environments.
Why choose the MI‑Jack-specific DEF Head Unit?
Engineered for direct compatibility with MI‑Jack chassis and Cummins ISB engine control systems, this OEM-quality module offers plug-and-play integration and factory-aligned calibration. It helps prevent dosing inconsistencies, SCR diagnostic errors, and engine derates common to off-brand components. Built to withstand heavy-duty rail and lifting applications, it delivers emissions control you can trust under tough jobsite conditions.
