Cummins X15 SCR 2022-2024: OEM 5507242

Reliable NOx Conversion for Cummins X15 Engines (2022–2024)

What is it?
The Cummins X15 SCR (Selective Catalytic Reduction) assembly with OEM part number 5507242 is an emissions aftertreatment component made for Cummins X15 diesel engines built between 2022 and 2024. Working together with Diesel Exhaust Fluid (DEF), this unit helps transform nitrogen oxides (NOx) in the exhaust into nitrogen and water before the gases exit the system, supporting regulated exhaust behavior.

Why choose this SCR Assembly?
This SCR module is engineered to Cummins’ original standards for the X15 platform, delivering accurate fitment and dependable interaction with DEF delivery components, exhaust sensors, and engine control systems. Over time, SCR performance can decline due to wear or contamination, which may reduce NOx conversion effectiveness and trigger emissions system alerts. Installing the correct OEM-specified assembly helps maintain consistent emissions control and coordinated aftertreatment performance.

Key Benefits
✅ Designed specifically for Cummins X15 aftertreatment systems (2022–2024)
✅ Supports steady conversion of NOx through DEF interaction
✅ Helps sustain coordinated operation with related emissions components
✅ Direct-fit replacement — no alterations required
✅ Built to endure demanding exhaust conditions

Applications
This SCR assembly is ideal for medium- and heavy-duty trucks and commercial vehicles equipped with Cummins X15 engines manufactured between 2022 and 2024. It’s commonly used in long-haul tractors, regional freight rigs, vocational work vehicles, and other commercial platforms where reliable emissions behavior and compliance are essential.

Installation Notes
Before servicing, ensure the exhaust and aftertreatment system has fully cooled. Remove the existing SCR module and inspect nearby DEF lines, sensors, and mounting hardware for signs of wear, contamination, or soot buildup. Install the replacement assembly using proper seals and fasteners to achieve a secure, leak-free fit. After installation, clear any stored fault codes and verify correct aftertreatment behavior using diagnostic tools.

Final Thoughts
If your Cummins X15-equipped vehicle is showing NOx-related warnings, fluctuating emissions readings, or inconsistent aftertreatment behavior, replacing the SCR assembly with the correct OEM-specified part can help restore dependable exhaust treatment. The Cummins X15 SCR (OEM 5507242) plays an important role in managing regulated exhaust chemistry and supporting reliable vehicle operation over varied duty cycles.
