What You're Actually Buying
This is the full mirror assembly - housing, heated glass, power motor for remote adjustment, the whole unit that bolts to the mirror arm. Not just a glass kit. If your motor's dead or the housing's smashed from a loading dock incident, this is the part that fixes it, not a patch job.
Fits Cascadia 2018-2024, but Freightliner made running changes through that span - different camera integration on some trims for the mirror-cam systems, different wiring pigtails depending on options ordered. The base A22-73907-005 covers a lot of trucks but not automatically every single one with a heated power mirror.
Driver side and passenger side are different parts even though the number's similar in format - don't order blind off memory, pull the tag or the number stamped on the mirror base.
How These Cross Numbers Line Up
A22-75160-001 shows up as the headline OEM number because that's what a lot of parts books index this assembly under - same mirror, different catalog era or supplier update. Freightliner's done this before where a running production change gets a new part number but the physical mirror and mounting are unchanged.
The aftermarket crosses - FRCA-1401C-RS32, TR438-FRMCC-R, WA128-0221, UPI43702 - all point back to the same mirror geometry and wiring harness. Where these can bite you is the heater element connector pinout and whether your truck has the camera-mirror option or the plain heated power mirror. Two trucks sitting side by side in the yard can need different mirrors if one's got the surround-view package.
Bottom line - the interchange works because the mounting arm, motor assembly, and glass are common across these numbers, but the connector and any camera provisions are the variable. Match those before you hang it.

Frequently asked questions
Does A22-75160-001 fit my 2021 Cascadia?
Probably, but confirm by VIN or by pulling the number off your current mirror. 2018-2024 Cascadias had option packages - camera mirrors, different heater wiring - that changed what mirror they left the factory with. Give us either number and we'll check it against your truck before you buy.
Is this the same mirror as the WA128-0221?
Same physical assembly, yes - housing, motor, heated glass all cross over. WA128-0221 is one of the aftermarket cross numbers that references this same mirror. Confirm the connector matches your harness, especially if your truck's got a mirror-mounted camera.
Do I need driver or passenger side, and how do I know which one I have?
They're not interchangeable - different mounting angle and wiring routing. Look at the number stamped on your existing mirror base or check your VIN build sheet. If you're not sure, snap a photo of the mirror and bring it in or email it over, we'll match it up.
