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.

Best one yet
Best tasting Metamucil if you enjoy carbonation. Less sweet than regular (even the no added sugar version felt a bit overly sweet to me). Lemonade is a close second but a bit too expensive. Wish it would come with a scoop but I saved one from a different product and dropped it into the jar here.

Great product, dislike new 43oz size
Works well. Prefer the “fizzy” formula over all others. I recommend adding powder to your cup, fill 30-50% with cold water, then use a small handheld milk frother to blend. It’ll “foam” then settle, add you can add more water. (If you fill the whole cup with water right away it’ll overflow when it foams up.) I prefer to drink it quickly, before it starts to thicken into a heavy gel/paste. 3 star rating for 2 reasons: 1) Strongly dislike the food coloring! 2) They recently changed container size and shape. It used to be a 29oz cylinder, now it’s 43oz and more like a tub. The new format is too large for my kitchen vitamin drawer + too wide and heavy to grab with one hand. (I’ve included side by side pics here - didn’t think to take them until I’d already removed the 43oz label for recycling.) I saved my last 29oz canister and I’ve been decanting powder from the 43oz, keeping the 43oz in pantry storage.

Great product
I have been using Metamucil for a long time! I can tell a difference in using the plain and the vitamin variety. I feel a more energetic. I will not use this variety close to bedtime. It does fizz a lot. Only add a small amount of water to the glass and after the fizz settles down add more water. Great product!

Fantastic product, dont like the texture - mix with food. Still 10/10 💩🎉
Flavor Name: Orange, Size: 15 Ounce (Pack of 1)
Taste: While the product doesn’t taste bad, preparing it as directed results in a very mild orange flavor. -as a drink I would prefer more flavor. Texture: The psyllium husk absorbs water extremely quickly—even in cold or room-temp water—which is just the nature of the ingredient itself. Because it starts to gel so fast, you have to chug it, and even then it can be difficult to get down. (I personally gag at it, but I have sensory issues) If the gel like texture is an issue for you, I found it more palatable mixed into food with water on the side. Texture aside, the product itself is highly effective. Mixability: It doesn’t always mix smoothly and tends to clump. Again nature of the ingredient not the brand. The powder is very fine and non-gritty perfect for other mixings. Side effects: I had uncomfortable bloating the first time (2 scoops/ full glass), I recommend starting with (1 scoop or less/full glass) Dont rush it. Increase it from there as you grow tolerance. You may feel very full. - it helped me eat less!
