Overview

Put the passenger-side mirror arm back in order with this Premium door mirror arm cover in black for the right-hand side of the New Cascadia, the P4 body style built from 2018 through 2025. The curb-side arm cover is the one that meets dock posts, gate frames and low branches, and once it is split or gone the mirror arm and its harness sit exposed to road spray and salt for the rest of the winter. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Small Part, Whole Mirror Saved: The Cascadia RH Arm Cover Advantage

A broken cover is not a broken mirror. When the head, the glass, the heater and the adjustment are all still working, replacing the cover alone is the honest repair, and it costs a fraction of a full assembly. Getting the side right is the only thing to watch: this is the right-hand cover, and it is the black finish rather than chrome. Hold the old cover up against the new one before anything gets thrown away, because the left and right shells look close enough to fool you across a parts counter.

At FleetPro Parts & Tires we would rather ship the twenty-dollar part that ends the problem. This cover is a direct replacement for highly searched industry numbers including Freightliner 22-78606-509 and 22-78606-518, plus Automann 563.46114 and Torque TRM310500BR. It ships new at our Premium Aftermarket level with a 1-Year FleetPro Warranty.
