DEF Control Tailored for Tough Duty: Ford F-Series Cummins ISB 6.7L
What is it?
The Ford F‑650/F‑750 Cummins ISB 6.7 L DEF Head Unit is an OEM emissions control module designed specifically for medium-duty Ford trucks equipped with Cummins ISB 6.7 L engines. It accurately meters Diesel Exhaust Fluid (DEF) into the exhaust stream to reduce nitrogen oxide (NOx) emissions; integrated sensors continuously monitor fluid level, temperature, and pressure to ensure stable dosing and SCR function.
Why choose the OEM Ford F‑650/F‑750 DEF Head Unit?
Built to match Ford chassis specs and Cummins ECM calibration, this DEF Head Unit ensures plug‑and‑play fitment and eliminates fitment issues or compatibility errors that come with aftermarket options. Its factory-level precision helps prevent SCR fault codes, engine derates, and inconsistency in DEF delivery—ensuring reliable emissions control and vehicle uptime.
Key Benefits
✅ Direct-fit for Ford F‑650 and F‑750 trucks with Cummins ISB 6.7 L engines
✅ Precisely meters DEF to max NOx reduction and emissions compliance
✅ Integrated sensors monitor DEF fluid level, temp, and pressure in real time
✅ Built to resist DEF crystallization, vibration, harsh temps, and contaminants
✅ Minimizes risk of SCR errors, limp-mode activation, and downtime
Applications
Ideal for Ford F‑650/F‑750 chassis used in vocational applications: box trucks, delivery rigs, utility bodies, and emergency support vehicles. This DEF Head Unit ensures that emissions systems remain compliant and functional under frequent idle cycles, stop-and-go workloads, and harsh operating conditions.
Installation Notes
Before servicing, disconnect the battery and relieve pressure in the DEF system. Clean the DEF tank and connector interfaces to remove residue or crystallization. Install the unit with OEM-style connectors and ensure secure fluid and electrical fittings. After installation, clear fault codes and verify DEF dosing flow and sensor data with a diagnostic scan tool.
