What This Fairing Is
This is the rear section of the left-hand side fairing on a Cascadia — the panel that runs behind the cab along the frame rail and closes out the gap ahead of the drive axles. It is a body panel, not a structural part, but it carries a real aerodynamic job and it takes abuse from road spray, ice, and anything the trailer throws forward.
It mounts to the fairing support arms and brackets on the frame. The panel itself is the replacement item here; brackets, arms, hardware, and any trim strips are separate and are reused off the old assembly unless they are bent or cracked. Inspect them before you pull the new panel out of the box.
Left-hand means driver side in North American configuration. There is a matching right-hand piece and the two are not interchangeable — the mounting hole pattern and the contour at the rear edge are mirrored, so a right-hand panel will not hang correctly on the left side.
Why 22-74263-010 Crosses
22-74263-010 is the Freightliner number listed for the same left-hand rear side fairing position. It shares the base sequence with our headline number, 22-74263-000, and the difference in the trailing digits reflects a supplier or revision suffix rather than a different panel shape or a different mounting arrangement.
That is normal on Freightliner body panels. The base number identifies the panel and the side; the suffix tracks the production variant. When you are cross-referencing a fairing, the base sequence and the side callout are what actually determine whether the part hangs on the same brackets.
We list 22-74263-010 for identification only. PartStop is not affiliated with, endorsed by, or authorised by Freightliner or Daimler, and that number is here so you can match what is stamped or tagged on the panel you pulled off the truck.
Check Before You Order
Read the number off the old panel first. On Cascadia fairings the label is usually on the inside face, near an upper mounting flange, and it survives more crashes than you would expect. If the label is gone, take the number off the intact panel on the opposite side and confirm the side callout separately. Verify by VIN through a dealer parts counter if there is any doubt.
A cross-reference is a starting point, not a fitment promise. Cascadia side fairings changed across model runs and wheelbase configurations, and a panel that shares a number family can still sit differently on a truck with a different fairing support setup. Confirm by VIN or by the number on the part in your hand before you commit.

Frequently asked questions
Does 22-74263-000 replace 22-74263-010?
It is listed as a direct replacement for that position. 22-74263-010 is the Freightliner number for the left-hand rear side fairing and shares the same base sequence. Match the number on your old panel and confirm the side before ordering.
Do the brackets and support arms come with the fairing?
No. This is the panel only. Reuse the existing fairing support arms, brackets, and mounting hardware unless they are bent or cracked from the impact that took out the old panel. Straighten or replace bent support arms first, or the new panel will sit proud and flutter at road speed.
How do I tell left-hand from right-hand?
Left-hand is driver side in North American configuration. The panels are mirrored, so the mounting hole pattern and the rear edge contour will not line up if you have the wrong side. Hold the panel against the truck and check the hole spacing against the brackets before you start hanging fasteners.
