Cummins X15 SCR 2022-2024: OEM 5507241

Consistent Emissions Treatment for Cummins X15 Engines (2022–2024)

What is it?
The Cummins X15 SCR (Selective Catalytic Reduction) assembly, identified by OEM part number 5507241, is an emissions aftertreatment component used on Cummins X15 diesel engines built from 2022 through 2024. As part of the SCR system, it works with Diesel Exhaust Fluid (DEF) to help convert nitrogen oxides (NOx) in the exhaust into nitrogen and water before the gases exit the system, supporting compliance with emissions regulations.

Why choose this SCR Assembly?
This SCR module is made to Cummins’ original design specifications for the X15 platform, ensuring proper fitment and dependable integration with DEF delivery components, exhaust sensors, and engine control systems. Over time, SCR assemblies can wear or become less efficient due to normal use or contamination. When that happens, NOx conversion effectiveness can diminish and may trigger emissions system alerts. Installing the correct OEM-specified SCR helps sustain stable emissions control and coordinated aftertreatment performance.

Key Benefits
✅ Specifically designed for Cummins X15 aftertreatment systems (2022–2024)
✅ Supports dependable NOx conversion with DEF chemistry
✅ Helps maintain coordinated operation with related emissions parts
✅ Direct-fit replacement — no alterations required
✅ Built for heavy-duty exhaust environments

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 is typically used in long-haul tractors, regional freight rigs, vocational trucks, and other commercial platforms where dependable emissions performance and regulatory compliance are essential.

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

Final Thoughts
If your Cummins X15-equipped vehicle is showing signs of uneven emissions control, NOx-related alerts, or inconsistent aftertreatment behavior, replacing the SCR assembly with the correct OEM-specified component can help restore coordinated exhaust treatment and more reliable exhaust performance. The Cummins X15 SCR (OEM 5507241) plays a central role in maintaining emissions system balance and supports dependable vehicle operation across demanding duty cycles.
