Function of this part

The aftertreatment system treats exhaust gases after they leave the engine using components such as the DOC, DPF, and SCR catalyst. It controls soot and NOx emissions by trapping particulates and converting harmful gases into less harmful compounds.

Why this part matters

These components are central to emissions compliance on modern diesel trucks. Problems in the aftertreatment system can cause frequent regens, power derates, and down-time until the fault is corrected.

About the brand

Cummins engine parts are trusted for reliable power in a variety of heavy-duty truck and equipment applications.

Fitment & usage

Used OEM parts are a smart choice for controlling repair costs while still using original-equipment components. Always match the OEM part number(s) listed to your existing part, and consult your service manual, dealer, or technician if you are unsure about fitment.

Note: Because this is a used component, normal signs of wear such as scratches, discoloration, or light surface corrosion may be present. Refer to the product photos and information on Second Truck Parts for the best representation of the part you will receive.

Sharp suit
Color: Black, Size: X-Small, Color: Black, Size: X-Small
The quality of the suit is very nice. The material feels thick and does not feel cheap at all. My son and I were both very pleased with this three piece suit altogether. We went off of size recommendation and due to personal preference we both agreed if we weren’t already in time crunch we would’ve sized up one size. Still managed to make it work and looked very sharp. He is 5’10” 150lbs - size ordered extra small

Order 1 size larger.
Size: X-Large, Color: Blue White Plaid
Nice shirt. The size is not accurate by any stretch of the imagination. I wear size xl in shirts except for this one. An xl fits like a large. Other than that I like the shirt. I would've given it 5 stars if not for the sizing. I'll give away this one and order an xxl. Just order a size above what you wear and you'll be happy.
