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

PACCAR components support both Kenworth and Peterbilt trucks with OEM-grade fit and performance.

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.

Pretty Colors to Encourage Me to Walk!
Size: X-Large, Color: (601) Bittersweet Pink / Stone / Stone
Hum. Extra large does not seem extra large. I have a slender but size 10-10.5 foot. Will keep but was hoping for a looser fit. Bought to match an Under Armour walking outfit.

Deliciously Healthy Snack – Chomps Beef Sticks Are a Must-Try
Flavor Name: Original Beef
I recently had the pleasure of trying Chomps Beef Sticks, and I must say, they have quickly become my go-to snack for a variety of reasons. **Taste and Texture:** The taste of Chomps Beef Sticks is simply outstanding. Each bite is packed with a robust, savory flavor that perfectly balances the natural taste of high-quality beef with a blend of spices. The texture is just right – firm yet tender, making it easy to chew without feeling overly processed or tough. Whether you prefer the original flavor or the slightly spicier varieties, there’s a Chomps Beef Stick for every palate. **Ingredients and Nutrition:** What truly sets Chomps apart is their commitment to quality ingredients. These beef sticks are made from 100% grass-fed and finished beef, free from hormones, antibiotics, and artificial preservatives. As someone who is health-conscious, I appreciate that Chomps uses only natural ingredients, ensuring each stick is both nutritious and delicious. Each beef stick is high in protein, making it an excellent choice for a post-workout snack or a midday protein boost. Plus, they are Whole30 Approved, Keto Certified, and Paleo friendly, fitting perfectly into a variety of dietary plans. **Convenience:** Chomps Beef Sticks are incredibly convenient for on-the-go snacking. Their compact size makes them easy to toss into a gym bag, backpack, or purse. I’ve found them to be a perfect snack for hiking, traveling, or just keeping at my desk for a quick, healthy bite during busy workdays. **Sustainability:** Another aspect worth mentioning is Chomps’ dedication to sustainability. By sourcing grass-fed beef and adhering to humane farming practices, they ensure that their products are not only good for you but also better for the environment. This commitment adds an extra layer of satisfaction when enjoying their products. **Overall Experience:** Overall, Chomps Beef Sticks are a standout snack that combines taste, nutrition, and convenience in one package. Whether you’re a fitness enthusiast, a busy professional, or just someone who loves a tasty and healthy snack, Chomps Beef Sticks are worth trying. I highly recommend giving them a try – you won’t be disappointed! **Rating: 5/5** Chomps Beef Sticks have earned a permanent spot in my snack rotation, and I’m sure they will in yours too. Happy snacking!
