What You're Actually Buying
This is the lower hood-mounted mirror on the driver's side, not the upper convex spotter mirror. It's got the heating element built in for winter fog and ice, plus the mounting arm that bolts to the hood bracket. Cascadia's been running this basic mirror design since 2008 with some running changes along the way.
Freightliner made small updates to the mirror housing and wiring harness over the years but kept the mounting points and arm length consistent enough that this part covers a wide production run, 2008 through current 2026 builds. That's why one number works across almost two decades of trucks.
Why All Those Other Numbers Cross
A2275354000 replaced some earlier Freightliner part numbers as they updated the heating element or wiring connector, but the mirror body, arm, and mounting pattern stayed the same. That's why A2273902000 and A22-73566-000 show up as valid cross-refs; Freightliner just renumbered the part when they tweaked something on the inside, not the outside.
Automann's AM56346091 and the 563.46091 number are the aftermarket and Freightliner catalog equivalents built to the same mounting and wiring specs. A22-76915-000 and A22-77791-000 are additional Freightliner service numbers that show up depending on which parts catalog year you're pulling from, and A22-77791-008 is listed as a current OEM reference.
The thing to watch on any hood mirror swap is the wiring connector pin count and the arm mounting bolt pattern. If your truck's got a different connector or the arm holes don't line up with what's on the hood bracket now, you've got a different generation part. Pull the number off your old mirror or run your VIN before you order, because Cascadia went through a few mirror generations and we want you ordering the right one the first time.

Frequently asked questions
Does A2275354000 fit my 2015 Cascadia?
Likely yes, this number covers 2008 through 2026 Cascadias, but confirm by checking the number stamped on your old mirror or giving us your VIN. Freightliner ran a few different mirror generations in there and we want to make sure your wiring connector matches before you order.
Is this the same as the Automann AM56346091?
Yes, that's the Automann aftermarket cross for this same mirror. Same mounting, same heating function, same fit. We just carry it under the Freightliner OEM number for cross-reference purposes.
Will this come with the wiring harness and heater already connected?
Yes, the heating element is built into the mirror glass and the pigtail connector is attached. You'll plug it into your existing hood harness, you're not splicing anything unless your truck's got a non-standard connector, which is rare but happens on some special builds.
