Cummins X15 SCR 2022-2024: OEM 5507152

Engine-Matched NOx Treatment for Cummins X15 Engines (2022–2024)

What is it?
The Cummins X15 SCR (Selective Catalytic Reduction) assembly with OEM part number 5507152 is a key emissions aftertreatment component for Cummins X15 diesel engines built between 2022 and 2024. Paired with Diesel Exhaust Fluid (DEF), this module supports the chemical conversion of nitrogen oxides (NOx) in the exhaust into nitrogen and water before the gases leave the system, helping the engine remain compliant with emissions standards.

Why choose this SCR Assembly?
This SCR module is manufactured to meet Cummins’ original design specifications for the X15 platform, ensuring the correct fit and dependable interaction with DEF delivery components, emissions sensors, and engine control systems. Over time, SCR units can lose effectiveness due to wear or contamination, which may reduce NOx conversion efficiency and trigger emissions warnings. Installing the correct OEM-specified SCR helps maintain coordinated exhaust treatment and more predictable aftertreatment performance.

Key Benefits
✅ Designed specifically for Cummins X15 aftertreatment systems (2022–2024)
✅ Promotes reliable NOx conversion with DEF chemistry
✅ Supports coordinated operation with emissions sensors and controls
✅ Direct-fit replacement — no modifications required
✅ Built for demanding exhaust conditions and heavy-duty use

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

Installation Notes
Allow the exhaust and aftertreatment system to cool completely before servicing. Remove the existing SCR module and inspect surrounding DEF lines, sensors, and mounting hardware for signs of wear or soot buildup. Install the replacement SCR assembly using appropriate seals and fasteners to ensure a secure, leak-free fit. After installation, clear any stored system codes and verify correct SCR performance using diagnostic tools.

Final Thoughts
If your Cummins X15-equipped vehicle is showing NOx-related warnings, inconsistent emissions readings, or irregular aftertreatment behavior, replacing the SCR assembly with the correct OEM-specified component can help restore smoother emissions control. The Cummins X15 SCR (OEM 5507152) plays an important role in managing regulated exhaust chemistry and supporting dependable vehicle operation across demanding duty cycles.
