What You're Getting
This is the left-hand hood-mounted mirror assembly, chrome housing, with the heating element wired in for winter runs. It bolts to the fender/hood mounting point on the Cascadia, not the door - Freightliner uses both hood mirrors and door mirrors depending on spec, so make sure you're ordering for the right location before you check out.
Freightliner spread this part across almost two decades of Cascadia production, 2008 through current build. Somewhere in there they tweaked wiring harness connectors and a couple mounting details, which is exactly why you see multiple Freightliner part numbers all crossing to the same physical mirror.
Aftermarket versions like this one are built to bolt up the same way and carry the same heating function. We back it with our standard 6+ month warranty, same as everything else we sell.
Why All These Numbers Cross
A2275354000 shares the table with A2273902000, A2273566000, and the Freightliner service numbers A22-73566-002, A22-77791-010, A22-77791-006, and A22-77791-008. These aren't random guesses - Freightliner has reissued this mirror under new part numbers as they made small production changes, but the mounting pattern, arm length, and heater wiring stayed compatible across the range.
Automann's AM56346091 and FleetPro's F-3624-LS32 are aftermarket cross-references built to the same spec. Where you need to pay attention is the wiring connector - some model years switched pin configurations on the heater harness, so even though the mirror itself interchanges, you may need to check your connector before you order if you're not doing a straight swap.
Bottom line: pull the number off your old mirror or the sticker on the mounting bracket, and match it against this list. If your truck's a border-year model (right around a spec change), a VIN check with us is worth the extra two minutes.
Ordering From PartStop
We're in Tacoma and keep this mirror in stock because Cascadias are everywhere on I-5 and the ports - if you're local, same-day pickup or delivery is usually doable if you call ahead.
Ship nationwide too, and mirrors like this move fast enough that we're not sitting on old stock. If it doesn't fit or something's off with the heater wiring, we sort it out - just don't wait three months to reach out.
Confirm by VIN or by the number stamped on your old mirror before ordering. Chrome housing dents easy in shipping if it's mishandled, so inspect it before you toss the old core.

Frequently asked questions
Does A2275354000 fit my 2015 Cascadia?
Most likely yes, but give us your VIN or the number off your current mirror to be sure. Freightliner ran several part numbers across the '08-current Cascadia lineup for this same mirror, and the '15s can go either way depending on options and build date.
Is this the same as the Automann AM56346091?
They cross-reference to the same mirror assembly, mounting point, and heater function. Automann's is their own aftermarket build to that spec - functionally it's the same replacement, just packaged under their part number instead of ours.
My mirror doesn't have a heater plug - will this one still work?
It'll bolt up fine, but if your truck wasn't spec'd with heated mirrors you won't have the connector to plug it into. Check your dash switch for a heated mirror function first, or call us with your VIN before ordering.
