What 82750279 Actually Is
This is the passenger-side corner deflector that closes the gap between the bumper end and the fender on a VNL. It is molded plastic, not steel, and it carries an integrated cut-out for the fog lamp. Its job is airflow management around the bumper corner, so air is pushed around the tire and down the side of the tractor instead of tumbling into the wheel well.
It fails in predictable ways. Curb contact and low-speed parking damage snap the lower tab first. Road debris punches through the face. UV and repeated wash-bay heat make older panels chalky and brittle, so a mounting boss shears off when you torque the fastener. Once one tab is gone, wind load works the panel loose and the rest follow within a few thousand miles.
A missing deflector is not just cosmetic. You lose the aerodynamic function you paid for on a highway tractor, the fog lamp loses its surround and support, and the open corner lets spray and grit straight into the wheel arch. Fleets running long linehaul routes notice it on the fuel report before they notice it on the walkaround.
Why These Numbers Cross
Volvo and Mack share cab and hood architecture across several platforms, and body panels that touch no drivetrain component get carried across both parts catalogs under separate numbers. That is why 82750279 and 82750293 describe the same right-hand corner deflector geometry — same mounting pattern, same fog lamp cut-out, same curvature at the bumper end.
The numbers differ because the catalogs differ, not because the panel differs. When a shop pulls a number off a Mack invoice and a Volvo dealer quotes something else, both are pointing at one molding. Cross-reference lists like this exist so you can search either number and land on the same replacement instead of ordering twice.
These numbers are listed for identification only. PartStop is an aftermarket supplier and is not affiliated with, endorsed by, or authorized by Volvo, Mack, or any other manufacturer. Treat the cross as a starting point — it narrows the search, it does not confirm the fit on your specific unit.
Check Before You Order
Confirm side first. This is the RH panel. LH and RH deflectors mirror each other and will not swap. Then confirm the fog lamp cut-out matches what your bumper carries — pull the old panel, or what is left of it, and compare the opening and the tab locations against the photos before you commit.
Verify by VIN or by the number stamped or molded into the back of the original panel. VNL bumper hardware changed through the 2018–2025 run and trim level affects what is fitted at the corner. If the old part is destroyed and you have no number, run the VIN. That is the only way to be certain, and it takes less time than a return.
82750279 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 82750279. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Is 82750293 the same part as 82750279?
They cross to the same right-hand corner bumper air deflector. One number comes off the Mack catalog, one off the Volvo side, but the panel geometry and mounting points are the same. Confirm against your old part or by VIN before ordering.
Can I run the truck without the corner deflector?
Mechanically, yes — nothing safety-critical bolts to it. But you lose the airflow management at the bumper corner, which shows up in highway fuel numbers, and the open corner lets spray and road grit into the wheel arch. The fog lamp also loses its surround and support.
How long does it take to install?
It is a bolt-on plastic panel with basic hand tools, and one person can do it. Budget extra time if the old panel snapped off and left broken tabs or seized fasteners in the bracket. Chase the threads and inspect the mounting bracket before you set the new deflector in place.
