Engineered for Industrial Endurance: Capacity Cummins ISB 6.7 L DEF Head Unit
What is it?
The Capacity Cummins ISB 6.7 L DEF Head Unit is a factory-calibrated emissions control module designed for heavy-duty Capacity-built vehicles powered by Cummins ISB 6.7 L engines. It precisely meters Diesel Exhaust Fluid (DEF) into the exhaust stream to reduce nitrogen oxide (NOx) emissions. Integrated sensors monitor DEF fluid level, temperature, and pressure to ensure dependable SCR system operation in high-demand industrial settings.
Why choose the Capacity-specific DEF Head Unit?
Purpose-built for Capacity chassis and Cummins ISB engine platforms, this OEM-grade module ensures plug-and-play installation with factory ECM programming and harness compatibility. It avoids issues like DEF dosing inconsistencies, SCR diagnostic codes, and engine derates common with aftermarket units. Constructed for reliability in heavy-load, continuous-use environments, it delivers emissions compliance where uptime matters most.
