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.

Good product, but...
Color: Dark Black, Size: 1 Pack
Easy to install. Like the product. The holder does not hold the phone position. It flops down alot.

The Perfect Phone Mount.
Color: Dark Black, Size: 1 Pack
It’s the perfect size, easy to install, and works perfectly. I have a 15 pro max iPhone, and it fits perfectly.

Well built and removes cleanly.
Color: Dark Black, Size: 1 Pack
Seems to be very solid and it was a little bit tricky to get it located on the vent blade properly, though that might just be due to the vents shape in my Highlander. I really like that it can be easily moved from one vehicle to another if needed without leaving adhesive residue like my last mount did. The only concern I have is whether the vent blade will support the weight long term. Time will tell I guess. EDIT: This fits all of the vents on my 2011 Highlander great. On my 2022 Highlander it will only attach to the center vents and then just barely hooks on after angling the vent blades enough for the hooks to grab. Even then the mount only makes contact at the very top and bottom of the vent opening. It works, but I wouldn't recommend it as ideal.

Best phone holder I have ever purchased!
Color: Dark Black, Size: 1 Pack
Hands down the best phone holder I have ever purchased. The ones that stick to the windshield always end up coming loose. This attached to your vent and is super sturdy. Very easy to install and uninstall without making a mess on your window.
