What This Panel Does
The middle fairing panel is the center segment of the side skirt that runs between the front fairing and the rear fairing on the right-hand side of a Cascadia. It closes the gap between the cab and the drive axles, keeps air attached along the tractor flank, and shields the fuel tank area and frame rail from spray and debris.
It is a molded panel, not a structural member. It hangs on brackets and clips off the frame and the adjacent fairing sections. That means a damaged panel does not put the truck out of service on its own, but a flapping or missing skirt kills fuel economy, throws road grit into the tank straps and steps, and looks rough on a DOT walkaround.
This is the right-hand panel. Left and right are not interchangeable — the mounting hole pattern and the contour are mirrored. Confirm which side you are looking at before you order, and count the fairing sections on the truck so you know you need the middle piece and not the forward or rear one.
How These Panels Fail
Most failures are impact. Curb strikes at loading docks crack the lower edge. A blown trailer tire on the neighbouring lane throws casing into the skirt and splits it along a mounting boss. Once a boss tears out, the panel loses tension, starts to vibrate at highway speed, and works the remaining fasteners loose until the whole section drops on one corner.
The second pattern is fastener and bracket fatigue. Constant flex at 65 mph elongates the mounting holes. Drivers find the panel sitting low or rubbing the tire. Before you order the panel, pull it and inspect every bracket, clip and retainer behind it — replacing the skin onto bent hardware just repeats the failure in a few thousand miles.
Check the mating edges on the front and rear fairing sections too. If the middle panel took a hit hard enough to crack it, the adjoining sections often have stress marks or broken tabs at the overlap that you will not see until the new piece is offered up.
Why These Numbers Cross
22-73738-016 and A22-76266-038 identify the same right-hand middle fairing panel on the Cascadia. Freightliner reissues fairing part numbers when tooling, bracketry or a running production change moves through the line, so the same physical panel can carry more than one number depending on the build date of the truck and which parts catalog the shop is reading from.
The 'A' prefix on A22-76266-038 is a Freightliner assembly-level designator. Trucks built in different windows can show either number on the build sheet while the panel on the frame is dimensionally the same part in the same location. That is why both numbers land on the same aftermarket line.
These interchange numbers are listed for identification only. PartStop is not affiliated with, endorsed by, or authorised by Freightliner or any other OEM. Use the cross-reference as a starting point, then confirm against the number stamped or labelled on the panel you pulled, or against the truck's VIN build record.
22-73738-016 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 22-73738-016. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Will 22-73738-016 fit my Cascadia?
It is a direct replacement for the right-hand middle fairing panel on Cascadias that call for this position. We do not promise fitment from a cross-reference alone. Pull the old panel and read the number on it, or run the VIN against the build record, then match it to 22-73738-016 or A22-76266-038 before you order.
Is A22-76266-038 the same part as 22-73738-016?
Yes — both numbers point to the same right-hand middle fairing panel. Which number a given truck shows depends on build date and the catalog revision in use. If your old panel or build sheet carries either number, this aftermarket panel is the corresponding line.
Do I need to replace the brackets when I change the fairing panel?
Inspect them, and usually yes if the panel was torn loose rather than just cracked. Elongated holes, bent brackets and stretched clips will let the new panel flex and fail the same way. Fairing panels ship as the panel itself, so plan hardware separately if the old set is damaged.
