What This Mirror Is and Where It Bolts On
This is the passenger-side hood-mount mirror, heated element built in, made for the 2018+ Cascadia hood-mirror setup Freightliner switched to. It's not the door mirror - it's the smaller one mounted low on the hood corner that gives you a look down the side of the truck for tight docking and curb checks.
Heated element matters in the Northwest more than guys want to admit - fog and frost on that low mirror in October mornings is a real visibility problem, not just a comfort item. This one carries the heat circuit stock, no aftermarket rigging needed.
Freightliner assigns more than one number to this depending on production run and whether it came through parts or as a running-change replacement, which is why you'll see A2275354001 and A227390200/A2273902000 all pointing at the same mirror.
Why These Numbers Cross and What to Check Before You Order
A2273902000 is the headline number we stock this under, and it cross-references to A2275354001 and the OEM A22-77790-008 listing. These aren't different mirrors with similar part numbers - Freightliner updated the number scheme on this bracket/mirror combo at least once without changing form or fit.
Where guys get burned on hood mirrors isn't the mirror head itself, it's the mounting bracket and heater plug connector - Freightliner changed the harness plug on some builds mid-2018. Pull the old mirror and check the plug pin count against what you're ordering, or better yet, read the number stamped on the mirror base or bracket.
If your truck's title or build sheet says 2018 or newer Cascadia and the old mirror is heated with a similar mount, this is very likely your part - but 'likely' isn't 'guaranteed,' so confirm against the VIN or the number off the broken mirror before you commit.

Frequently asked questions
Does A227390200 fit my 2019 Cascadia?
Most likely yes if it's the RH heated hood mirror, but confirm by checking the number on your old mirror or giving us your VIN - Freightliner ran a couple bracket/connector variations across 2018-2019 builds.
Is this the same mirror as the Freightliner OEM A22-77790-008?
Yes, A22-77790-008 is the Freightliner OEM listing for the same mirror this aftermarket part cross-references to. Same mounting and heater function, just sourced through the aftermarket instead of the dealer counter.
How do I know if I need the RH or LH side?
RH is passenger side, LH is driver side - stand behind the truck facing forward to get your bearings. Check the old mirror's number if it's still legible, that's the fastest way to confirm before ordering.
